Free USMLE Step 1 Ethics and Communication practice questions

Valid research consent must be voluntary, free of coercion and undue influence. A physician who is both a patient's long-term clinician and the study investigator holds a dual role, and this patient's words show that she fears losing her physician's goodwill or care if she declines. Agreement given under that pressure is not truly voluntary. The appropriate step is to reduce the influence of the therapeutic relationship: have a research coordinator or other team member who is not involved in her care present the study, give her the consent form to read, allow time (including taking it home and talking with family), and make clear that declining will not affect her care in any way. Many IRBs require exactly this separation when investigators recruit their own patients.

A. Her agreement reflects a wish to please her physician, not an informed, voluntary decision; she has not even read the consent form. B. Appealing to altruism adds pressure and does not address her stated fear; consent discussions should be balanced, not persuasive. C. Calling an investigational drug safe misstates uncertainty (the purpose of the trial is to evaluate safety and efficacy), and pressing for a signature before she leaves undermines voluntariness. E. Excluding her without discussion is paternalistic and denies an eligible patient the chance to make her own choice; the fix is to remove the pressure, not the option.

Most angry patients can be helped with calm listening and acknowledgment of their frustration, but once a patient makes a threat of harm and shows threatening body language (standing, clenched fists, moving toward the clinician), the physician's personal safety comes first. The appropriate action is to leave the room, which she can do because she is next to the open door, and summon hospital security or follow the institution's behavioral emergency procedure. Occupational safety guidance for health care workers emphasizes keeping an exit path open, not being alone with a threatening person, and using trained staff for de-escalation. After safety is assured, the team can reassess the patient (including intoxication, withdrawal, or psychiatric illness), document the event, and continue to offer appropriate care.

A is wrong because verbal de-escalation is appropriate for an upset patient, but continuing a face-to-face discussion after an explicit threat and approach puts the physician at risk. B is wrong because giving an unindicated controlled substance in response to intimidation rewards threats and is not good medical care. D is wrong because closing the door isolates the physician with a threatening patient and blocks her exit. E is wrong because touching an agitated, threatening person can be perceived as aggression and can provoke violence.

Whole-body CT screening in asymptomatic people has no proven benefit for reducing mortality, and no professional society recommends it. Its harms are real: ionizing radiation exposure, and frequent incidental findings (small renal, adrenal, liver, lung, and thyroid lesions) that are usually benign but lead to anxiety, further imaging, biopsies, and complications (overdiagnosis and a cascade of testing). Physicians are not required to order tests that are not indicated, even when a patient will pay. The best response takes his worry seriously, explains the balance of harms and benefits in plain language, and redirects him to evidence-based screening that he is actually due for, such as colorectal cancer screening, which the USPSTF recommends starting at age 45.

B is wrong because who pays does not change whether a test is medically appropriate or whether it can harm him. C is wrong because low-dose chest CT is recommended only for adults aged 50 to 80 with a significant smoking history, and he has never smoked. D is wrong because screening abdominal ultrasound in an average-risk 45-year-old is also not indicated (ultrasound screening for abdominal aortic aneurysm applies to men aged 65 to 75 who have ever smoked) and can still produce incidental findings. E is wrong because sending him elsewhere avoids the counseling the physician owes him.

The emergency exception allows treatment without consent when a patient lacks capacity, delay would cause serious harm, and no surrogate is available. Its justification is implied consent: the assumption that the patient would want lifesaving care. That assumption does not hold when the patient has already made her wishes clear. A specific, recent, signed refusal made by an adult while she had capacity is an advance directive and must be honored even when she can no longer speak for herself. This woman's card explicitly refuses all blood products even at the risk of death, so transfusion should be withheld. She should still receive every other indicated treatment: surgical control of bleeding, crystalloid, hemostatic agents, tranexamic acid, cell-saving strategies if acceptable to her, and minimizing blood loss from sampling. The decision and the document should be recorded carefully, and the family contacted when possible.

A. The emergency exception applies only when the patient's wishes are unknown; it does not override a known, valid refusal.

C. An advance refusal does not have to be completed in a hospital to be valid; a signed, witnessed card stating a specific refusal is a clear expression of her wishes.

D. Courts may be asked to authorize transfusion for minors, but not to override a capable adult's clearly documented refusal.

E. Transfusing while waiting for family would violate the refusal she already made; family cannot add to or revoke it in the meantime.

Confidentiality protects the patient's diagnosis, but it is not absolute when an identifiable third party faces a serious, preventable risk of harm. His wife is a known person at ongoing risk of HIV acquisition, and she cannot protect herself without knowing.

The ethically preferred sequence is to first counsel the patient and encourage him to disclose, offering help, which the physician has already done. When he still refuses, the physician should use the public health route. HIV infection is reportable in every US state, and health department partner services notify exposed partners that they may have been exposed and should be tested, without naming the index patient. This protects the wife while limiting the breach to the minimum necessary. Many states also permit, but do not require, the physician to notify a spouse directly after telling the patient of the intent to do so; the health department route remains the standard, lawful first choice. The physician should tell the patient what will happen and continue his care.

A is wrong because silence leaves an identifiable person at continuing risk. C is wrong because disclosing to a relative is an unnecessary breach to someone with no role in protecting the wife or in public health. D is wrong because treatment cannot be made conditional on disclosure; therapy that suppresses his viral load also lowers transmission risk. E is wrong because HIV exposure is a public health matter, not a police matter, and involving law enforcement is an excessive disclosure.

Adolescents are much more likely to disclose sensitive information, such as mood, substance use, sexual activity, safety at home and online, and suicidal thoughts, when they are interviewed alone. Professional guidelines recommend that from early adolescence (about age 11 to 12), part of every visit be spent with the adolescent without the parent present, using a structured psychosocial history such as HEEADSSS (home, education, eating, activities, drugs, sexuality, suicide and depression, safety).

The best way to do this is to normalize it: tell the parent that this is routine practice for all adolescents, invite the parent back at the end, and explain the rules of confidentiality to both of them together. The adolescent should hear that what she says will stay private unless there is a risk of serious harm to her or to others, or suspected abuse. Framing it as a standard part of care rather than a reaction to the mother's behavior preserves the parent's trust.

A is wrong because adolescents commonly withhold sensitive information in a parent's presence, so key risks would be missed. B is wrong because screening is a core part of adolescent preventive care and should not be deferred. C is wrong because a questionnaire completed next to the parent is not private. D is wrong because a parent's report is not a reliable substitute for the adolescent's own history on sensitive topics, and the question bypasses the patient.

Motivational interviewing is a patient centered counseling style that helps patients resolve ambivalence about behavior change. This patient is in the contemplation stage: she recognizes the harms and has a reason to change (her grandchildren) but also perceives a benefit of smoking (stress relief). The core skills are open ended questions, affirmations, reflective listening, and summaries (OARS). A double sided reflection restates both sides of her ambivalence, which shows empathy and invites her to elaborate on her own reasons for change (change talk). Patients are more likely to change when the arguments for change come from them rather than from the clinician.

A is wrong because confrontational warnings provoke defensiveness and resistance, the opposite of the collaborative MI spirit. B is wrong because it minimizes her experience and offers premature reassurance rather than exploring her concerns. C is wrong because it moves directly to action (pharmacotherapy and a quit date) before she has resolved her ambivalence; this fits the preparation stage, and pushing ahead risks disengagement, although pharmacotherapy should be offered when she is ready. E is wrong because "why" questions with an implied criticism sound judgmental and make patients defend the status quo.

Every adult is presumed to have decision-making capacity unless an assessment shows otherwise, and an intellectual disability or genetic diagnosis does not by itself remove the right to decide. Capacity is judged for the specific decision, and physicians should support the patient's decision-making with simple language, visual aids and extra time. This man, using such supports, communicates a clear choice, understands what the procedure involves and its risks, appreciates that it applies to his toe, and gives a sensible reason. He has capacity for this decision. Because no court has appointed a guardian, his mother has no legal authority to consent on his behalf; parents of adult children are not automatic decision-makers. The physician should obtain consent from the patient himself, and with his permission, his mother can stay involved as a support person.

A. Next of kin become surrogates only when a patient lacks capacity; he has capacity for this decision.

B. Consent from a capable adult does not require a co-signer, and requiring one would undermine his autonomy.

C. Guardianship is not needed for a capable adult and would be inappropriate to pursue in this setting.

D. An IQ score does not determine capacity; the assessment focuses on his abilities regarding this decision.

A DNR order is not automatically suspended when a patient goes to the operating room. Professional guidance from anesthesiology and surgical societies calls for required reconsideration: before surgery, the surgeon and anesthesiologist meet with the patient (or surrogate) to review the DNR order in light of the procedure. Many interventions that would count as resuscitation on the ward, such as intubation, vasopressors, and fluid boluses, are routine parts of anesthesia, and arrests caused by anesthesia are often rapidly reversible.

The options include keeping the DNR order as written, suspending it fully for the perioperative period, or a goal-directed or procedure-directed approach (for example, accepting airway management and vasopressors but declining chest compressions, or accepting treatment of reversible anesthesia-related events). Whatever she decides should be documented and communicated to the whole team, along with when the original order resumes. This respects her autonomy and avoids both overtreatment and undertreatment.

A is wrong because automatic suspension ignores her wishes and is no longer accepted practice. B is wrong because patients with DNR orders can benefit from palliative surgery, and a DNR order is not a reason to deny it. C is wrong because she has capacity, so she decides her own code status. D is wrong because the order may be interpreted inconsistently in the operating room unless its meaning for anesthetic care is clarified with her.

When a physician discovers a possible error by another clinician, the patient is still owed honest information. The physician should answer his direct question truthfully with the facts she knows: the earlier radiograph shows a small nodule in the same place. At the same time, she should avoid speculation or blame, because she may not know the full context (image quality, the clinical question, or what was communicated).

Current guidance recommends that the physician gather the facts and talk with the other clinician (or that facility's quality or risk office) so that, ideally, the clinician involved can participate in a full disclosure and the facility can review its process. The primary aim is to make sure the patient learns what happened, by one route or another, while the physician focuses on his urgent diagnostic workup.

A is wrong because it is a lie and violates the duty of honesty. B is wrong because labeling the care negligent is premature, unfair to the colleague, and outside her role; whether care fell below the standard requires review. C is wrong because withholding information until the patient retains a lawyer is evasive and harms trust. D is wrong because a blanket refusal to discuss another clinician's care leaves the patient uninformed about something that matters to him.
