Core Ethical Principles
1. A 28-year-old pregnant woman with fetal distress on monitoring. The physician recommends an emergency C-section, but the patient declines and insists on vaginal delivery. What ethical principle supports her right to refuse the procedure?
➔ Autonomy
- Note: 1st Core ethical principle
Autonomy – Respect for a patient’s right to make their own decisions. Includes: - Informed consent
- Right to refuse treatment (even if it leads to death, unless public health is at risk)
- Maternal autonomy (pregnant patient can refuse C-section even if mother or child is in danger)
2. A 72-year-old man with end-stage cancer is given high-dose opioids for severe pain, which may hasten death. What ethical principle supports this action?
➔ Principle of double effect
- Note: Principle of double effect – Prioritizing comfort over side effects (e.g., opioid use for terminal patients).
- Beneficence: acting in the patient’s best interest
3. A 55-year-old man with severe aortic stenosis is denied surgery due to an 80% predicted intraoperative mortality rate. What principle supports this decision?
➔ Nonmaleficence
- Note: 3rd Core ethical principle
Nonmaleficence – “Do no harm.” - Weigh risk vs. benefit of any treatment.
- Example: Avoiding surgery if intraoperative mortality is high.
4. During the COVID-19 pandemic, limited ICU beds were given to patients with the highest chance of survival. What ethical principle guides this decision?
➔ Justice
- Note: 4th Core ethical principle
Justice – Fair treatment and resource distribution. - Example: Triage decisions in an emergency room.
Decision-making capacity and Informed Consent
5. A 67-year-old man with metastatic cancer refuses chemotherapy. He understands the diagnosis, can describe risks and benefits, and expresses the same choice across multiple discussions. What’s the next step?
➔ Respect his decision
- Note: A patient has decision-making capacity if:
- Understands his condition and options.
- Appreciates the consequences of choices.
- Reasons and weighs options rationally.
- Expresses a choice consistently.
Important scenarios: - Psychiatric patients can have decision-making capacity if intact.
- Suicidal patients automatically lack capacity.
- Patients can lose capacity but still have autonomy (e.g., dementia, Down syndrome).

6. A 45-year-old woman needs a central line for emergent hemodialysis. Who should talk with the patient and her family regarding the informed consent?
➔ The surgeon who inserts the CV line
- Note: Informed consent: For moderate to high-risk procedures. For things like IV catheter placement that are low risk, verbal consent is enough. The highest-ranking person in the team with the most experience should talk to the patient and explain these key elements:
- Benefits of the procedure
- Risks of the procedure
- Alternative treatments
- Indications/Nature of procedure
7. An unconscious 22-year-old man is brought to the ER after an accident. He is bleeding profusely and requires an urgent blood transfusion. No family members are present. What to do next?
➔ Proceed with blood transfusion (in an emergency situation, consent is applied unless proved otherwise)
- Note: Exceptions to Informed Consent (WIPE mnemonic):
- Waiver – Patient voluntarily waives consent.
- Incompetence – Decision by legal surrogate.
- Privilege (Therapeutic) – If disclosure would cause severe harm.
- Emergency – Implied consent for life-saving treatment.
8. A 16-year-old girl seeks treatment for a sexually transmitted infection and requests not to tell her parents. What’s the next step?
➔ Proceed with the treatment
- Note: Consent for minors: (General rule: Parents provide consent.)
Exceptions where minors can consent themselves (without parents): - STIs, contraception, pregnancy (not abortion in all states)
- Substance use treatment
- Legal emancipation (married, military, self-supporting)
- Emergency treatment (Will treat the minor even if the parents do not consent.)
9. A 35-year-old Jehovah’s Witness with a bleeding gastric ulcer refuses blood transfusion. He is alert, oriented, and understands the consequences. What is the appropriate next step?
➔ Respect the patient’s decision and do not administer the transfusion
- Note: Refusal of Treatment
- Competent adults can refuse treatment, even if life-threatening.
- Parents can refuse treatment for children unless:
- Emergency treatment is needed (e.g., blood transfusion for a child with trauma).
- A court order is obtained for vaccines or serious interventions.
- Note: Jehovah’s Witnesses always refuse transfusion of blood. Two common scenarios for the USMLE:
1. If patient is adult and refuses transfusion: Respect their decision.
2. If patient is minor and the parents refuse transfusion to the kid: Proceed with the transfusion;
10. A 58-year-old man hospitalized for pneumonia insists on leaving the hospital against medical advice. What should the physician do?
➔ Assess capacity, explain risks, and document the informed refusal
- Note: Leave Against Medical Advice (AMA)
- Assess capacity before discharge.
- Document the risks of leaving AMA and ensure informed refusal.
- Reassess AMA patients regularly (they may return for care).
- Tell the patient he can come back anytime if he changes his decision.
11. A 29-year-old man tells his psychiatrist that he is planning to harm his coworker the next day. What is the physician’s legal obligation?
➔ Warn the potential victim (Tarasoff duty)
- Note: Patient information is confidential, unless (WAIT A SEC Mnemonic):
1. Wounds (gunshot/knife wounds – must notify the police)
2. Automobile-driving impairment
3. Infectious disease (TB, STIs, COVID-19)
4. Tarasoff Duty (duty to warn potential victims of harm)
5. Abuse (child, elder, or prisoner)
6. Suicide risk
7. Elder abuse/neglect
8. Child abuse
12. A 70-year-old man is hospitalized without an advance directive or designated medical power of attorney. Patient is in a coma. Who should be consulted to make medical decisions on his behalf?
➔ His spouse
- Note: Advance Directives (in order)
- Written Advance Directive (Living Will) – Outlines treatments a patient wants or refuses.
- Medical Power of Attorney – Designates a decision-maker.
- Oral Advance Directive – Must be specific, repeated, and informed.
- Hierarchy of Decision Makers (Surrogates):
1. A durable power of attorney (if designated).
2. Spouse > Adult children > Parents > Siblings > Other relatives.
They should consider what the patient would have wanted if he/she had capacity.
13. A patient with metastatic cancer is admitted to the ICU for pneumonia. He has a valid Do Not Resuscitate (DNR) order in place. What to do next?
➔ Proceed with antibiotics
- Note: Do Not Resuscitate (DNR) / Do Not Intubate (DNI) ≠ “Do not treat”
- Patients may still receive palliative care, dialysis, or blood transfusions.
- High-Yield Scenario: We perform CPR and intubate a patient. One hour later, we find out the patient has a DNR and DNI (do not intubate) order. We have to extubate the patient and continue other palliative treatments, even if this means that the patient dies. Not intubating from the start = Extubating as soon as we learn about the DNI.

Hospice care and alternative therapies
14. A 68-year-old man with metastatic pancreatic cancer refuses chemotherapy. His prognosis is less than 6 months. What type of care is most appropriate?
➔ Hospice care
- Note: Hospice Care: A form of palliative care for patients with ≤6 months prognosis when curative/life-prolonging treatment is no longer beneficial. Medication for pain relief is ethical even if it shortens life.
15. A 45-year-old woman with breast cancer asks about using herbal remedies in addition to chemotherapy. The physician has not heard about the herb before. What is the physician’s most appropriate response?
➔ Explore her beliefs and tell her he’ll look into the herb until her next appointment
- Note: Alternate Therapies
- Physicians should explore why a patient requests alternative therapies before dismissing them.
- Ethical obligation: Discuss benefits/risks without dismissing the patient’s beliefs.
- If a patient insists on nonstandard therapies, close follow-up is necessary to monitor for toxicity.
16. A patient requests a full-body CT scan “just to be sure” despite no clinical indication. What should the physician do?
➔ Decline the request and educate the patient on risks and the lack of benefit
- Note: Avoid unnecessary testing and procedures.
- Use evidence-based guidance to maintain trust.
Sexual Assault
17. A 23-year-old woman presents after sexual assault. She is emotionally distraught but alert. What’s the next step?
➔ Offer postexposure prophylaxis for HIV, chlamydia, gonorrhea, and trichomoniasis
- Note: Sexual Assault
- High risk for PTSD, depression, and suicidality.
- Evaluation: physical examination, forensic evidence collection, and psychological assessment.
- Postexposure prophylaxis for chlamydia, gonorrhea, trichomoniasis, and HIV.
- If the patient doesn’t want you to call the police, respect her decision.
- Make sure she has somewhere safe to go after discharge.
Special situations
18. A 14-year-old boy with perinatally acquired HIV is nonadherent to treatment. He doesn’t know he has HIV. What should the physician do?
➔ Inform the adolescent of his HIV status to promote adherence and reduce transmission risk
- Note: Disclosure of HIV status in children should occur in adolescence to promote adherence and prevent transmission.
Note: If a kid has HIV and is adherent to treatment, we can wait till they’re adolescent to disclose the condition.
19. A 35-year-old man with schizophrenia becomes increasingly agitated in the ER, clenching his fists and shouting. What is the most appropriate initial step?
➔ Maintain a safe distance and use verbal de-escalation techniques. (Choices like restraining or antipsychotics are almost always incorrect, unless we have already tried non-confrontational strategies)
- Note: Violent Patient Management
- Risk factors: psychiatric illness, substance use, and previous violent behavior.
- Warning signs: include loud speech, clenched fists, and pacing.
- Management: Maintain physical distance, de-escalate verbally, offer food and drink, and use non-confrontational approaches.
- Chemical and physical restraints should be a last resort.
20. A physician frequently arrives late to work, gives inappropriate orders, and smells of alcohol. What is the physician colleague’s responsibility?
➔ Report the physician to the Physician Health Program (PHP)
- Note: Physician Impairment: impaired ability to practice medicine due to psychiatric illness, medical conditions, or substance use.
Keywords: lateness, slurred speech, conflicts with staff, and inappropriate orders.
Reporting to a Physician Health Program (PHP) is required; refusal may lead to reporting to the state medical board.
Note: If a physician is drunk while visiting patients, make sure he stops visiting right away. Report as soon as possible to find a replacement for that shift.
21. A man with end-stage pancreatic cancer requests that you give him “something to end it quickly.” What is your response?
➔ Refuse to assist in physician-assisted suicide
- Note: Physician-assisted suicide is illegal in most U.S. states
- Providing medication to relieve suffering (e.g., opioids) is ethically and legally acceptable, even if it unintentionally shortens life.
- Intent = symptom relief → acceptable, Intent = cause death → not acceptable.
22. A 30-year-old female patient expresses romantic interest in her physician and asks him out on a date. What should be the physician’s response?
➔ The physician should politely decline
- Note: The physician must respectfully decline and, if necessary, transfer care
- Romantic or sexual relationships with current patients are unethical and unprofessional, even if the patient initiates or consents.
23. A patient becomes angry in the waiting room after a long delay and raises their voice at the front desk. What is the most appropriate initial response by the physician?
➔ Acknowledge the frustration and apologize for the wait “I understand this wait has been frustrating. I’m sorry for the delay”
- Note: If behavior escalates to impending violence, offer food or a drink.
24. An 82-year-old woman with dementia is brought by her son. She has bruises on her arms and appears fearful. She avoids eye contact and gives vague answers. What is the next best step?
➔ Interview the patient alone
- Note: Always interview the patient separately when abuse is suspected
- Look for inconsistent history, poor hygiene, bruises, fear
- Elder abuse must be reported to Adult Protective Services (APS)
25. A 6-year-old girl comes to the ER with a spiral femur fracture. Her parents report she “fell off the bed.” On exam, you see multiple healed bruises. What is the next best step?
➔ Report to Child Protective Services (CPS)
- Note: Suspicious signs: spiral fractures, inconsistent stories, multiple bruises, burns, fear of caregiver
- Physicians are mandated reporters. Reporting does not require proof, just reasonable suspicion
26. A 28-year-old woman comes for a routine check-up. She has facial bruises and says she “fell down.” You ask if she feels safe at home, and she begins to cry. What is the most appropriate next step?
➔ Ensure safety and offer resources
- Note: Screen privately and directly: “Do you feel safe at home?”
- Provide resources, such as IPV hotlines and shelters. Do not force reporting.
- Respect her autonomy; offer follow-up and support
27. A 58-year-old man with hypertension has persistently high blood pressure despite multiple prescriptions. He later admits he hasn’t been taking his medications. What is the most appropriate initial response?
➔ Ask why he is not taking the medications
- Note: First step = nonjudgmental, open-ended questions. Let the patient explain in their own words:
○ “Can you tell me what’s been going on with your medications?” - Common reasons: [Side effects, Cost, Misunderstanding, and Cultural beliefs]
- Once the barrier is identified, tailor the solution, and build a shared decision-making.
28. A 45-year-old man is declared brain dead after trauma. The family refuses to allow withdrawal of life support, claiming “he moved his foot, he’s still alive.” What should the physician do?
➔ Explain brain death as legal death and proceed with withdrawal of support
- Note: Brain death = legal death in all U.S. states. support can be withdrawn despite objection.
- Explain clearly:
○ Brain death = irreversible loss of all brain and brainstem activity
○ Spinal (peripheral) reflexes (e.g., toe movement) can persist, do not mean brain function - Family may need time, support, and a clear, compassionate explanation.
- Common signs of brain death:
○ No pupillary, corneal, oculocephalic, or gag reflexes
○ No spontaneous respiration (apnea test positive)
○ Coma and absence of cerebral activity
29. A 63-year-old man is admitted with new-onset cancer. His adult children ask for details about his diagnosis and prognosis. What should you do?
➔ Respect the patient’s wishes and withhold information
- Note: Confidentiality applies even within families. You must not share details without explicit permission. They can talk directly to the patient.
- Exceptions:
○ The patient lacks capacity
○ Legal surrogate requests information
○ Emergency involving an immediate threat to others.
30. A patient brings a hand-knit scarf to her doctor as a holiday gift. What should the physician do?
➔ Accept the gift if it is of modest value and does not influence care
- Note: Accepting Gifts from Patients
- Avoid large or expensive gifts.
- Small tokens (cards, baked goods) may be acceptable.
- If accepting a gift could influence care, it must be declined.
Doctor-Patient Professional Boundaries - Intimate relationships with current patients are unethical.
- For psychiatrists, an intimate relationship even with a previous patient is unethical.
31. A 59-year-old Spanish-speaking man is admitted with chest pain. His adult daughter offers to interpret for him. What is the most appropriate next step?
➔ Use a professional medical interpreter
- Note: Interpreters
- Use qualified medical interpreters (not family members).
- Address the patient directly, not the interpreter.

- Note: Institutional Review Board (IRB): Required for all projects with human subjects.
Informed Consent for inclusion in research is required. Exceptions: - Studies using secondary data (e.g., medical charts).
- Studies without patient identification.
35. A clinical trial compares a hypertension drug with a placebo to manage emergency hypertension. What is the ethical concern in this context?
➔ Using a placebo is unethical because it withholds proven lifesaving therapy and exposes patients to unacceptable risk
- Note: Ethical Considerations for Randomized Controlled Trials (RCTs)
- Equipoise: The intervention must not be proven superior.
- Control Groups: Control must not pose unacceptable risks.
- Stopping Trials: Trials must stop if interim data shows highly significant harm/benefit.

- Purpose: Reduce cognitive overload and diagnostic errors, especially in busy or complex settings.
- Effective in combating cognitive biases and improving the quality of care.
46. A hospital identifies a physician with a significantly higher cesarean delivery rate compared to peers. What is the most effective method to reduce unnecessary procedures?
➔ Provide data-driven feedback comparing the physician’s performance to peers
- Note: Practice Variation & Feedback in Quality Improvement
- High Variation in Care → Often reflects overuse of services & lower quality/value of care.
- Main Cause → Differences in provider practice styles.
- Effective Intervention → is data-driven feedback comparing individual performance to Peers and Evidence-based benchmarks
47. A physician orders routine daily labs for a stable hospitalized patient without clinical indication. What principle of high-value care is being violated?
➔ Resource stewardship — labs should be ordered based on clinical need to avoid unnecessary cost and waste
- Note: High-Value Care & Resource Stewardship
- Value = Quality ÷ Cost
- Quality Components: Outcomes, Safety, Patient experience (satisfaction, wait times)
- Cost Components: Total cost across the entire care episode
- Resource Stewardship:
○ Avoids unnecessary tests/interventions
○ Promotes evidence-based, cost-effective care
48. A patient undergoes surgery on the wrong site. The team did not confirm identity or site before incision. What step was missed?
➔ Time-out (Universal Protocol)
- Note: Universal Protocol
- Goal: Prevent wrong-patient, wrong-site, wrong-procedure errors
- Key Steps:
– Pre-op verification (patient ID, procedure, site) → using medical records and patient input
– Site marking by provider
– Time-out: A final pause by the entire surgical team immediately before incision → to confirm patient identity, procedure, and site)
49. A hospital has persistently low hand hygiene compliance despite adding more sinks and dispensers. What is the next best step to improve adherence?

– Build hand hygiene into evaluations - Culture Interventions:
– Form safety teams
– Provide real-time feedback
50. A hospital introduces simulation drills for cardiac arrest and airway emergencies using mannequins and video feedback. What is the primary purpose of this intervention?
➔ Improve provider performance and patient safety through simulation-based training
- Note: Simulation Training
- Rehearses high-risk scenarios in a safe environment
- Improves team communication and emergency response
- Reduces errors by identifying system gaps
- Commonly used for ACLS, trauma, OB, and neonatal codes
51. A physician is treating a patient from a different cultural background who relies on family to make decisions. What is the most appropriate next step?
➔ Respect the patient’s cultural norms and involve family in shared decision-making
- Note: Cross-Cultural Care
- Goal: Improve outcomes and communication, especially in minority populations.
- Key Principles:
○ Patient-centered care: Align with patient’s values and preferences.
○ Cultural sensitivity: Respect sociocultural beliefs; avoid stereotyping.
○ Effective communication: Use professional interpreters, adjust style to patient norms (e.g., eye contact, family involvement).
52. An 80-year-old woman is admitted after a fall resulting in a hip fracture. She is on multiple medications including benzodiazepines and anticholinergics. What strategy can reduce her risk of future falls and adverse drug events?
➔ Review medications using Beers Criteria and start fall prevention
- Note: Beers Criteria: List of medications potentially inappropriate for elderly due to higher risk of side effects.
- Elderly Care: Falls & Polypharmacy
○ Falls are a leading cause of morbidity in elderly → assess gait, vision, environment
○ Polypharmacy increases risk of adverse drug events and falls
○ Use Beers Criteria to identify potentially inappropriate meds (e.g., benzodiazepines, anticholinergics, NSAIDs)
○ Multidisciplinary care and physical therapy reduce fall risk
53. A hospitalized patient develops sustained tachypnea and new-onset arrhythmia. What is the most appropriate next step to reduce risk of deterioration?
➔ Activate the Rapid Response Team (RRT)
- Note: Rapid Response Teams
- Purpose: Early intervention in clinical deterioration to prevent cardiac arrest and reduce mortality.
- Team: Multidisciplinary (e.g., nurse, physician, respiratory therapist).

- Impact: Improves outcomes; supports frontline providers in high-risk situations.
Medical errors
54. A nurse has prepared a double dose of insulin. She is caught just before administering the drug. How is this classified?
➔ Near miss—an error that was intercepted before causing harm
- Note: Types of Medical Errors
- Near Miss: Error caught before reaching the patient (e.g., wrong insulin dose detected before injection)
- Active Error: Occur at the point of care (e.g., administering the wrong IV medication)
- Latent Error: System flaws that enable errors (e.g., similar packaging for different meds)
- Never Evens: Serious, preventable errors (e.g., surgery on the wrong site)
55. A hospitalized patient undergoes surgery on the wrong limb. The hospital initiates an immediate investigation and reports the event to national safety authorities. What type of event is this?
➔ Sentinel event
- Note: It is an unexpected death or serious harm
- It requires immediate investigation and reporting
- Examples:
– Wrong-site surgery
– In-hospital suicide
– Retained surgical item
56. A patient develops a nerve injury after surgery. The complication is non-preventable and was recognized during the procedure. What is the most appropriate next step?
➔ Disclose the complication to the patient
- Note: Disclosure of Medical Errors
- Duty of Disclosure: Physicians must disclose all significant complications, whether preventable or not.
- Responsibility:
– Ideally, the physician directly involved should lead the discussion.
– If unavailable, a covering physician should provide an honest preliminary explanation and follow up - Team-Based Disclosure: When multiple providers are involved, a collaborative approach is recommended.
57. A 78-year-old woman with multiple chronic conditions is admitted for taking the wrong doses of her drugs. During discharge, what strategy can help prevent the next adverse drug event?
➔ Teach Back method to confirm her understanding
- Note: Adverse Drug Events:
Risk factors: polypharmacy, frequent provider changes, and communication issues.
Best practices for prevention: - Use plain-language instructions (e.g., “take in the morning and at bedtime”)
- Clearly specify intervals (e.g., ‘wait 1 hour before the second dose’).
- Use the Teach Back method: ask the patient to explain how they will take their medications to ensure understanding
58. A physician discovers that a colleague may have ordered an incorrect HIV test without proper consent. What is the most appropriate next step?
➔ Speak privately with the colleague to understand what occurred
- Note: Peer Error: If another provider may have made an error:
- Speak privately and nonjudgmentally with the colleague.
- Obtain patient consent before sharing PHI if no current patient-provider relationship exists.
- The physician in charge must ultimately inform the patient once facts are confirmed.
59. A patient is transferred for imaging, and afterward, telemetry alarms fail to trigger during an arrhythmia. The patient was improperly reconnected to the monitor. What is the most likely cause?
➔ Failure at the patient-device interface
- Note: Telemetry Errors
- Failure at the level of the device-human interface is the most common cause of inpatient telemetry-related errors:
– Example: disconnection of the patient from or improper connection of the patient to the telemetry device - Other causes are equipment malfunction, communication breakdown, and alarm fatigue.
- Prevention Strategies:
– Checklists & standardized handoffs for patient transfers
– Routine telemetry equipment checks
– Forcing functions (e.g., volume-limited alarms not allowed)
60. A 28-year-old man with a history of anxiety presents with chest pain. Based on his history, the physician diagnoses a panic attack and does not order an ECG, even after the patient reports worsening pain and shortness of breath. What type of cognitive error occurred?
➔ Anchoring bias
- Note: Anchoring bias is fixating on an initial diagnosis despite new conflicting data VS confirmation bias involves actively seeking information that supports the initial diagnosis and dismissing contradictory evidence
| Bias | Definition | Example |
|---|---|---|
| Anchoring | Fixating on initial impression despite conflicting data | Diagnosing GERD despite red flags like weight loss |
| Availability | Overemphasizing recent or memorable diagnoses | Diagnosing flu during flu season when actual cause is PE |
| Confirmation | Seeking data that supports initial diagnosis; ignoring contradictory evidence | Presuming pneumonia in a patient with cough and fever; the physician orders only a chest X-ray and ignores signs pointing to pulmonary embolism. |
| Framing | Influenced by how info is presented or by context | Opioid withdrawal assumed due to “drug-seeking” label—actual cause is SBO |
61. A young man with chest pain is described by paramedics as “having a panic attack.” In the emergency department, the physician reassures the patient without performing an ECG. The patient later develops cardiac arrest. What type of cognitive error occurred?
➔ Framing bias – Clinical judgment is influenced by how a case is presented or labeled, rather than objective evaluation
62. A physician unintentionally assumes a Black patient is exaggerating pain and delays offering adequate analgesia. What is the most likely explanation for this behavior?
➔ Implicit bias
- Note: Implicit Bias
- Definition: Subconscious, nondeliberate stereotypes or attitudes toward a group (e.g., race, gender).
- Effect: Influences clinical judgment and contributes to health disparities (e.g., undertreatment of pain).
- Management:
○ Self-reflection and group debriefing.
○ Metacognitive strategies to recognize and challenge biased thinking
63. During rounds, a resident pauses to critically reflect on their differential before finalizing a diagnosis in a complex patient. What cognitive strategy is being used to reduce diagnostic error?
➔ Metacognition – It is the process of reflecting on and monitoring one’s own thinking to identify potential cognitive errors or biases
64. A hospital adopts overlapping safety protocols, such as barcode scanning and two-person medication verification, to reduce errors. What error prevention model is being used?
➔ Systems approach (Swiss cheese model)
- Note: Systems Approach to Error Prevention
- Definition: Focuses on organizational and team-based solutions rather than blaming individuals.
- Example: Swiss cheese model: Multiple system layers prevent error progression despite occasional failures in each (“holes”).
- Zero human error is unrealistic. The realistic and safety-focused goal is zero preventable harm (no adverse events).

65. A hospital installs syringe pumps that only accept matching cartridges. What human factors engineering strategy is this?
➔ Forcing function
- Note: Most Reliable Human Factors Engineering
- Forcing Functions (Most reliable error-prevention method):
– Hard stops in design to eliminate incorrect use
– Examples include:
– Anesthesia gas connectors that only fit correct ports
– OR equipment that won’t power on without safety checks
– EHR requiring weight entry before dosing heparin - Computerized Automation: Automated processes to reduce human effort and error variation (e.g., automated vital signs monitoring).
- Environment & Physical Layout: Optimizing workspace design to minimize errors (e.g., storing look-alike drugs in different locations).
66. While entering medication orders, a physician is interrupted by a nonurgent question from a nurse. What is the most appropriate action to ensure patient safety?
➔ Finish the current task before addressing the interruption
- Note: Minimizing Interruptions
- Interruptions during critical tasks (eg, order entry, medication reconciliation) are a known source of preventable medical errors.
- Best practice: Complete the current uninterrupted task before responding to nonemergency interruptions.
- Timeouts before tasks like surgical counts improve situational awareness, reduce interruptions, and enhance team vigilance.
67. During interdisciplinary rounds, a pharmacist notices a medication discrepancy and speaks up, preventing a potential error. Which communication strategy does this scenario best illustrate?
➔ Interdisciplinary rounds
- Note: Interdisciplinary rounds are team-based meetings where healthcare professionals collaboratively plan and coordinate patient care.
- The most common root causes of sentinel events involve failures in communication and teamwork
Top Communication Strategies for Patient Safety
| Strategy | Key Purpose | HY Benefit |
|---|---|---|
| Standardized Handoff | Structured info exchange | Prevents omissions & errors |
| Closed-Loop | Confirming the message via repeat-back | Reduces miscommunication or pronunciation errors |
| Interdisciplinary Rounds | Multidisciplinary patient review | Enhances safety, shared oversight |
68. During a shift handoff, the outgoing resident gives a rushed verbal report without written notes and omits a pending CT scan on a critically ill patient. What communication strategy could best reduce this type of error?
➔ Use a structured handoff template with written and oral communication
- Note: Reducing Errors in Patient Handoffs
- Use a structured template (eg,checklist), (the most effective intervention to improve signout safety).
- Combine oral + written communication
- Emphasize to-do items (read-back when needed)
- Give anticipatory guidance (eg, “If BP drops, give fluids”)
- Encourage questions to clarify care plan
69. A hospital launches a new error reporting system but notices that staff are rarely submitting reports about near misses. Which of the following most likely explains this underreporting?
➔ Lack of clear criteria for what should be reported
- Note: Error Reporting Systems (ERS)
- Staff report errors & near misses (eg, med error)
- Most effective when hospitals:
○ Investigate reports systematically
○ Provide feedback to reporters
○ Promote a nonpunitive culture (confidential, no retribution)
○ Include all frontline staff
○ Use clear criteria for what to report
○ Ensure reporting is quick & easy
70. During morning rounds in the ICU, a nurse reminds the team that a patient’s antibiotics were not reordered. The team acknowledges the oversight and updates the orders immediately. What key feature of an effective health care team is demonstrated in this scenario?
➔ Responsiveness
- Note: Features of Effective Teams
- Responsiveness: Acting promptly on feedback
- Psychological safety: Team members feel safe to speak up
- Collaboration: Coordinated teamwork across roles
- Transparency: Disclosure of errors or risks
- Safety culture: Organizational focus on safety systems
71. A medical student observes a complex surgical procedure and notices a potential sterility breach but hesitates to speak up due to fear of being wrong or reprimanded. Which intervention is most likely to improve the student’s future willingness to voice safety concerns?
➔ Team safety debriefings
- Note: Team Debriefings & Psychological Safety
- Team safety debriefings (before/after events) promote open communication and continuous learning
- Improve psychological safety: comfort in speaking up without fear of blame
- Encourages junior team members to participate in safety discussions
72. A physician becomes emotionally withdrawn after several patient deaths in the ICU. Which of the following interventions is most appropriate to help mitigate burnout and support physician well-being?
➔ Interdisciplinary debriefing sessions
- Note: Debriefing for Physician Well-being
- Interdisciplinary debriefings focus on psychosocial aspects of care
- Associated with reduced burnout and improved team support
73. A resident writes a medication order for “5.0 mg” morphine. The patient receives 50 mg due to misreading. What prescribing principle was violated?
➔ Avoid trailing zeros when writing medication doses
- Note: Safe Prescribing Practices
- No trailing zeros: Write “5 mg” not “5.0 mg”
- Use leading zeros: Write “0.5 mg” not “.5 mg”
- Clearly write units: Use “mcg” or “mg” — avoid abbreviations like “U” for units
- Use computerized order entry when possible
74. A surgeon caring for a patient fails to follow standard protocol during surgery, causing permanent nerve damage. Which element of malpractice does this represent?
➔ Deviation from the standard of care (breach)
- Note: Medical malpractice requires:
- Duty: Established physician-patient relationship (implied by surgeon responsible for care)
- Deviation from standard (Breach): Failure to follow accepted standard of care
- Direct Causation: Direct link between breach and patient harm
- Damages: Actual injury or disability caused by the breach
75. A physician orders a CT scan for a patient with low-risk abdominal pain, primarily to avoid missing a rare diagnosis and potential legal consequences. The scan is not clinically indicated. What practice is this an example of?
➔ Defensive medicine
- Note: Defensive medicine: Ordering tests or treatments mainly to avoid liability, not to benefit the patient.
- Leads to overuse, higher costs, and possible harm (e.g., radiation).
- Clinical pathways/guidelines: Evidence-based tools that help standardize care and reduce liability when followed.

| Medicare | – Age ≥ 65 – OR permanent disability (≥24 months on SSDI) – OR ESRD – OR ALS |
| Medicaid | – Low income + limited assets |
77. A 45-year-old uninsured man presents to the ED with severe chest pain. The triage nurse mentions he has no insurance. What is the most appropriate next step?
➔ Perform a medical screening exam and provide stabilizing treatment
- Note: EMTALA (Emergency Medical Treatment and Labor Act)
- Federal law requires EDs to evaluate and treat anyone with a possible emergency, regardless of insurance or ability to pay.
- Provides:
– Medical screening exam
– Stabilizing treatment
– Appropriate transfer if needed
78. A patient with health insurance must pay 20% of the cost of services after meeting their deductible. What is this type of patient cost-sharing called?
➔ Coinsurance

Core Ethical Principles
1. Autonomy – Respect for a patient’s right to make their own decisions. Includes:
- Informed consent
- Right to refuse treatment (even if it leads to death unless public health is at risk)
- Maternal autonomy (pregnant patient can refuse C-section)
2. Beneficence – Act in the best interest of the patient.
- May conflict with autonomy (e.g., adult Jehovah’s Witness refusing transfusion).
- Principle of double effect – Prioritizing comfort over side effects (e.g., opioid use for terminal patients).
3. Nonmaleficence – “Do no harm.”
- Weigh risk vs. benefit of any treatment.
- Example: Avoiding surgery if intraoperative mortality is high.
4. Justice – Fair treatment and resource distribution.
- Example: Triage decisions in an emergency room.
Decision Making Capacity
A patient must be able to:
- Understand their condition and options.
- Appreciate the consequences of choices.
- Reason and weigh options rationally.
- Express a choice consistently.
In the exam:
- Psychiatric patients can have decision-making capacity if intact.
- Suicidal patients automatically lack capacity.
- Patients can lose capacity but still have autonomy (e.g., dementia).
Disclosure and Informed Consent
Full Disclosure: Patients have the right to know about their medical condition and treatment options, as well as the legal right to access their medical records within a specified timeframe. Therapeutic Privilege: Doctors may withhold information if disclosure would cause severe harm (e.g., suicide risk).
Key elements (BRAIN mnemonic):
- Benefits
- Risks
- Alternatives
- Indications/Nature of procedure
Exceptions to Informed Consent (WIPE mnemonic)
- Waiver – Patient voluntarily waives consent.
- Incompetence – Decision by legal surrogate.
- Privilege (Therapeutic) – If disclosure would cause severe harm.
- Emergency – Implied consent for life-saving treatment.
Consent for minors: (General rule: Parents provide consent.) Exceptions where minors can consent themselves (without parents):
- STIs, contraception, pregnancy (not abortion in all states)
- Substance use treatment
- Legal emancipation (married, military, self-supporting)
- Emergency treatment (Will treat the minor even if the parents do not consent.)
Vaccination & Public Health
Routine vaccines: Parental refusal is tolerated (except in outbreaks). Tetanus prophylaxis is urgent and should be given regardless of parental refusal.
Refusal of Treatment
- Competent adults can refuse treatment, even if life-threatening.
- Parents can refuse treatment for children unless:
○ Emergency treatment is needed (e.g., blood transfusion for a child with trauma).
○ A court order is obtained for vaccines or serious interventions.
- Leave Against Medical Advice (AMA)
○ Assess capacity before discharge.
○ Document risks of leaving AMA and ensure informed refusal.
○ Reassess AMA patients regularly (they may return for care).
Confidentiality
General Rule: Patient information is confidential. Exceptions (WAIT A SEC Mnemonic):
- W Wounds (gunshot/knife wounds – must notify the police)
- A Automobile-driving impairment
- I Infectious disease (TB, STIs, COVID-19)
- T Tarasoff Duty (duty to warn potential victims of harm)
- A Abuse (child, elder, or prisoner)
- S Suicide risk
- E Elder abuse/neglect
- C Child abuse
End of Life Issues
Advance Directives
- Oral Advance Directive – Must be specific, repeated, and informed.
- Written Advance Directive (Living Will) – Outlines treatments a patient wants or refuses.
- Medical Power of Attorney – Designates a decision-maker.
- Do Not Resuscitate (DNR) Order – Prohibits CPR.
- Hierarchy of Decision Makers (Surrogates):
- A durable power of attorney (if designated).
- Spouse > Adult children > Parents > Siblings > Other relatives.
They should consider what the patient would have wanted if he/she had capacity.
Do Not Resuscitate (DNR) / Do Not Intubate (DNI) ≠ “Do not treat”
- Patients may still receive palliative care, dialysis, or blood transfusions.
- If the physician finds out about the DNR after intubating the patient, they should extubate.
Withdrawal of Life-Sustaining Treatment
- Competent patients can refuse life-sustaining treatment.
- No psychiatric evaluation is needed if the patient has capacity.
- Withdrawal ≠ euthanasia. It is an ethical cessation of non-beneficial treatment.
Palliative and Hospice Care
- Palliative Care: Comfort-focused medical care, regardless of prognosis.
- Hospice Care: Form of palliative care for patients with ≤6 months prognosis when curative/life-prolonging treatment is no longer beneficial. Medication for pain relief is ethical even if it shortens life.
Note: The physician should not provide futile treatment, even if the patient insists.
Alternate Therapies
- Physicians should explore why a patient requests alternative therapies before dismissing them.
- Ethical obligation: Discuss benefits/risks without dismissing the patient’s beliefs.
- If a patient insists on nonstandard therapies, close follow-up is necessary to monitor for toxicity.
Doctor Patient Professional Boundaries
- Sexual relationships with current patients are always unethical.
- No clear guidelines for relationships after termination of care.
Accepting Gifts from Patients
- Avoid large or expensive gifts.
- Small tokens (cards, baked goods) may be acceptable.
- If accepting a gift could influence care, it must be declined.
Use of Interpreters
- Use qualified medical interpreters (not family members).
- Address the patient directly, not the interpreter.
Key USMLE Scenarios
- A patient with decision-making capacity refuses life-saving treatment.
→ Respect their autonomy. - A Jehovah’s Witness parent refuses a blood transfusion for their child.
→ Override their refusal if it’s life-saving. - A minor wants STI treatment without parental consent.
→ Provide treatment. - A patient has a living will refusing ventilatory support but is now unconscious.
→ Follow the advance directive. - A suicidal patient refuses hospitalization.
→ Hospitalize involuntarily (loss of capacity). - A patient with tuberculosis refuses treatment.
→ Treat involuntarily (public health risk). - Patient refuses to take medication
→ Identify barriers and educate. - Family asks you not to disclose prognosis
→ Explain that patient autonomy prevails. - Physician colleague is impaired at work
→ Report to a supervisor.
Handling Difficult Patient Scenarios
- Refusal of treatment → Assess capacity and provide education.
- Requests for unnecessary procedures → Educate about risks vs. benefits.
- Disruptive family members → Maintain professional boundaries.
- Physician Relationships:
○ Romantic relationships with current patients are always unethical.
○ Termination of care before engaging in a relationship is required.
○ Romantic relationships with current or previous psychiatry patients are always unethical.
Adverse Drug Events
Preventable adverse drug events are associated with factors such as polypharmacy, frequent provider changes, and communication issues. Best practices for prevention:
- Use plain-language instructions (e.g., ‘morning and before bed’).
- Clearly specify intervals (e.g., ‘wait 1 hour before the second dose’).
- Ask patients to explain how they’re supposed to take their medications (Teach Back method).
- Ensure multiple team members independently verify medication reconciliation.
Sexual Assault
- Patients who experience sexual assault are at high risk for PTSD, depression, and suicidality.
- Evaluation includes physical examination, forensic evidence collection, and psychological assessment.
- Postexposure prophylaxis includes treatment for chlamydia, gonorrhea, trichomoniasis, and HIV.
Special Occasions
Pregnancy
- Informed consent during prenatal care should include cesarean delivery discussions (Preventive Ethics).
- A pregnant woman with capacity has the right to refuse treatment, even if it risks the unborn child.
- Physicians uncomfortable with cesarean deliveries should refer the patient to another provider.
Adolescence
- Disclosure of HIV status in children should occur in adolescence to promote adherence and prevent transmission.
- Collaboration with parents is necessary, but the child’s autonomy should be respected.
- Drug testing adolescents without consent is inappropriate; parents should be educated about limitations.
Violent Patient Management
- Risk factors include psychiatric illness, substance use, and previous violent behavior.
- Warning signs include loud speech, clenched fists, and pacing.
- Management: Maintain physical distance, de-escalate verbally, offer food and drink, and use non-confrontational approaches.
- Chemical and physical restraints should be a last resort.
Physician Impairment
- Defined as impaired ability to practice medicine due to psychiatric illness, medical conditions, or substance use.
- Signs include lateness, slurred speech, conflicts with staff, and inappropriate orders.
- Reporting to a Physician Health Program (PHP) is required; refusal may lead to reporting to the state medical board.
Key USMLE Scenarios
- A patient refuses treatment for a serious condition.
→ Assess decision-making capacity and provide education on risks and benefits. - A patient requests an unnecessary MRI for mild back pain.
→ Explain risks, lack of benefit, and potential harm from overuse of medical imaging. - You want to discharge an elderly patient hospitalized for an adverse drug reaction.
→ Use the Teach Back method to prevent future errors. - A pregnant woman refuses a C-section despite fetal distress.
→ Respect maternal autonomy while ensuring she is fully informed of risks. - A patient becomes violent in the hospital.
→ Use de-escalation techniques at first, not physical restraints.
Clinical Research Ethics
Key Principles (Based on the Declaration of Helsinki & Geneva)
- Patient well-being takes priority over research goals.
- Informed consent is required before enrollment.
- No undue compensation (only out-of-pocket costs can be covered).
- Confidentiality must be maintained.
- Vulnerable populations (e.g., incarcerated patients and minors) require extra protection.
- Must obtain guardian consent for children.
Note: Subjects may withdraw at any time without penalty.
Conflict of Interest (COI) in Research
- Increases risk of bias, especially in industry-funded research.
- Physicians should disclose conflicts (e.g., financial ties to pharmaceutical companies).
- No large or promotional gifts should be accepted.
- Small educational materials and meals at academic meetings are acceptable.
- Implement independent oversight of the research process.
Institutional Review Board (IRB)
Protects human subjects by approving or rejecting research protocols. Exemptions from Informed Consent for inclusion in research:
- Studies using secondary data (e.g., medical charts).
- Studies without patient identification.
Ethical Considerations for Randomized Controlled Trials (RCTs)
- Equipoise: The intervention must not be proven superior.
- Control Groups: Control must not pose unacceptable risks.
- Stopping Trials: Trials must stop if interim data shows highly significant harm/benefit.
Key USMLE Scenarios
- A research physician is found to have financial ties to a drug company sponsoring a study. → Disclose conflicts of interest and ensure independent oversight of the research.
- A clinical trial finds significant harm in the experimental group. → Stop the trial immediately and notify participants.
Hospital Readmissions and Quality Metrics
- Preventable Readmissions: Addressed via improved communication and follow-up.
- Multidisciplinary Clinics: Team-based approach for chronic disease management.
- Primary Care Follow-Up: Within 4 weeks of discharge to prevent readmissions.
Patient Centered Care
- Shared Decision-Making: Align treatments with patient values.
- Cultural Sensitivity: Address beliefs and sociocultural factors.
- Improving Health Literacy:
○ Use plain language.
○ Implement visual aids.
○ Encourage “teach-back” methods.
Cognitive Errors
Swiss Cheese Model: Errors occur when multiple layers of defense fail.
- Anchoring Bias: Sticking to initial diagnosis despite new evidence.
- Availability Bias: Overweighting recent/memorable cases.
- Confirmation Bias: Selectively focusing on supporting evidence.
Types of Medical Errors
- Active Errors: Occur at frontline (e.g., wrong IV dose).
- Latent Errors: System-level errors leading to patient harm.
- Never Events: Preventable serious errors (e.g., retained surgical sponge).
- Near Misses: Events that could cause harm but are caught before occurrence.
Medical Error Analysis Root Cause Analysis:
- Retrospective: Investigates why a failure occurred.
- Uses fishbone diagrams, 5-whys approach.
Created by ChatGPT.com
Failure Mode and Effects Analysis (FMEA):
- Prospective: Identifies potential failures before implementation.
- Prioritizes failures based on likelihood and impact.
Most Reliable Human Factors Engineering
- Forcing Functions: Hard stops in design to eliminate incorrect use (e.g., anesthesia gas fits only one compatible socket).
- Computerized Automation: Automated processes to reduce human effort and error variation (e.g., automated vital signs monitoring).
- Environment & Physical Layout: Optimizing workspace design to minimize errors (e.g., storing look-alike drugs in different locations).
Healthcare Communication
Error Reporting Systems (ERS):
- Encourages structured mechanisms for reporting incidents.
- Uses systematic investigation and feedback for process improvement.
- Reducing Errors in Handoffs:
- Use standardized sign-out templates.
- Encourage read-back verification.
- Limit interruptions during transitions.
