Medical Ethics OSCE Stations: 6 Practice Scenarios + 60 Free MCQs
Medical ethics OSCE stations rarely test whether you can recite ethical principles. They test whether you can recognise a professional dilemma, choose the safest next action, and communicate that decision clearly under pressure.
A patient refuses treatment. A relative asks for confidential information. A colleague appears unsafe to practise. What should you do first — and what would you actually say?
• 60 original scenario-based questions • Answers, reasoning, traps and OSCE transfer prompts
Scope: This revision resource is based primarily on current GMC professional guidance and the MLA framework. Specific legal rules can differ across England and Wales, Scotland and Northern Ireland; follow the legal framework and local guidance relevant to your course and placement.

What Makes a Medical Ethics OSCE Station Different?
A medical ethics OSCE station usually centres on a professional conflict or decision boundary: what the patient wants, what is clinically appropriate, what professional guidance permits, and what you should do next.
Unlike a station dominated by examination technique or diagnostic recall, ethics stations often make several actions look reasonable. The challenge is to identify the priority action for this patient, at this moment, in your role.
The core task: recognise the dilemma → protect safety → identify who can decide → apply the relevant duty → choose the next step → communicate it professionally.
If you are new to station structure, use our broader OSCE Stations guide for the parent framework, then return here for ethics-specific practice.
How Are Medical Ethics Actually Tested in OSCE Stations?
Ethics is rarely tested as a definition exercise. You are more likely to meet a patient refusing treatment, a family member requesting information, a young person asking for confidential care, or a colleague whose behaviour may place a patient at risk.
The current MLA Content Map explicitly includes medical ethics and law within professional knowledge, including ethical duties in Good medical practice and the legal duties that apply to practitioners. The map also emphasises communication, safeguarding, risk management and knowing when to escalate concerns.
Knowledge
What rule or duty applies?
Consent, capacity, confidentiality, safeguarding, candour, professional boundaries, fairness or patient safety.
Judgement
What should happen next?
Several actions may eventually be appropriate. The exam often tests priority, timing, proportionality and escalation.
Communication
What would you actually say?
OSCE performance makes your reasoning visible through respectful explanation, checking understanding and appropriate escalation.
Role
What are you responsible for?
An FY1, student, GP and consultant may share principles but differ in authority, escalation routes and procedural responsibility.
A 2026 peer-reviewed evaluation of a professionalism and ethics OSCE found that realistic rehearsal improved preparedness, while assessors identified difficulty articulating procedural next steps in ethically challenging situations. That is why this resource does not stop at naming a principle: every question asks you to decide what to do and then translate the decision into OSCE behaviour.
Why Students Find Ethics OSCE Stations Difficult
1. More than one answer can sound reasonable
After a medication error you may need to assess the patient, inform a senior, explain what happened, apologise, document it and submit an incident report. All may be appropriate eventually.
The exam question is often: Which action is correct now?
2. Ethical and professional duties can conflict
Autonomy may conflict with beneficence. Confidentiality may conflict with preventing serious harm. Parental wishes may conflict with a child’s welfare. The task is not to recite every principle; it is to decide what matters most in the actual scenario.
3. One fact can change the decision
A patient who refuses treatment but understands and weighs the consequences is very different from a patient whose acute delirium prevents meaningful decision-making. Capacity is not a label attached to a diagnosis; it is assessed for a particular decision at a particular time.
Primary guidance: GMC — Seven principles of decision making and consent.
4. Knowing the rule is not the same as performing it
In an OSCE, you must make reasoning visible: explain risk without coercion, listen to the patient, check understanding, escalate appropriately and maintain trust. For a broader performance structure, see the OSCE Template for medical students.
The OSCE.ai Ethics Decision Framework
This is a revision framework, not a clinical guideline. Use it to organise your thinking before applying the specific GMC, legal and local guidance relevant to the scenario.
1. SafetyIs anyone in immediate danger?
2. Decision-makerWho has authority for this decision?
3. PerspectiveWhat does the patient understand, want or fear?
4. DutyConsent, confidentiality, safeguarding, candour, fairness?
5. Next actionWhat must happen now rather than later?
6. CommunicateWhat should you say, escalate and document?
Check for immediate danger
If a patient is at immediate risk, safety may need to be addressed before the longer ethical discussion or reporting process.
Identify who is making the decision
Adult or child? Does the patient have capacity for this decision? Is another person legally authorised, or are relatives being consulted about the patient’s wishes?
Understand the patient’s perspective
What do they understand? What matters to them? Why are they making this choice? Is there coercion, fear or a communication barrier?
Identify the relevant duty
Consent, confidentiality, safeguarding, candour, professional boundaries, equality, patient safety or escalation?
Choose the next action
Separate the immediate priority from actions that are also correct but belong later in the sequence.
Communicate, escalate and document
Use clear patient-centred language, appropriate senior support, safety-netting and accurate documentation.
To understand how visible behaviours can translate into marks, see our OSCE Mark Schemes guide.
Eight High-Yield Medical Ethics OSCE Scenarios
1
Consent & treatment refusal
A patient refuses an investigation, admission or treatment. Check capacity, understanding, voluntariness, alternatives and safety-netting.
2
Capacity assessment
A confused or cognitively impaired patient makes a high-stakes decision. Capacity is decision-specific and time-specific.
3
Confidentiality
A relative requests information the patient has not agreed to share. Decide whether disclosure is justified, lawful and proportionate.
4
Children & young people
Confidential contraception, adolescent consent, parental disagreement and safeguarding may all appear.
5
Safeguarding
Recognise a reasonable concern and act through the appropriate safeguarding pathway; certainty is not always required before escalation.
6
Duty of candour
Protect the patient, assess harm, be open, apologise appropriately, report and support learning.
7
Professionalism & concerns
Unsafe colleagues, working beyond competence, bullying, digital professionalism and boundaries test patient-safety judgement.
8
End-of-life decisions
DNACPR, advance decisions and clinically inappropriate treatment require careful, individualised reasoning and communication.
Test Yourself: 6 Medical Ethics OSCE Practice Questions
Commit to one answer before opening the explanation. The point is not to recognise the rationale after you see it; it is to decide what should happen next from the information in the stem.
Scenario 1 — Treatment refusal
A 68-year-old man with pneumonia is advised to remain in hospital for intravenous treatment. He wants to go home. He accurately explains his diagnosis, the recommended treatment and the possibility that he could become seriously unwell if he leaves. There is no evidence of delirium, intoxication or coercion.
What is the most appropriate next step?
Show answer
Best answer: C
Why this is best: A medically risky or unwise choice does not itself establish incapacity. The patient demonstrates understanding of the relevant decision and consequences and there is no evidence that his choice is involuntary. Respect the decision, reduce avoidable risk, document and safety-net.
Principle tested: Capacity · autonomy · treatment refusal
Tempting distractor: B. “Unsafe decision” does not mean “incapable patient.”
What would change the answer? Acute delirium or another impairment preventing him from understanding, retaining, using/weighing or communicating the decision.
OSCE transfer: How would you check understanding without trying to pressure him into staying?
Primary guidance: GMC — Decision making and consent.
Scenario 2 — Relative asking for information
A competent patient has specifically asked the team not to discuss her cancer diagnosis with her daughter. The daughter asks: “Please, just tell me whether Mum has cancer.”
What is the best response?
Show answer
Best answer: B
Why this is best: A family relationship does not create an automatic right to confidential clinical information. You may listen to what the daughter wants to tell you and offer general support without revealing information the patient has asked you not to disclose.
Principle tested: Confidentiality · autonomy
Tempting distractor: A. “Close relative” does not equal “permission to disclose.”
What would change the answer? The patient explicitly authorising relevant information to be shared, or a separate legal/public-interest justification for disclosure.
OSCE transfer: How could you remain compassionate without confirming or denying the diagnosis?
Primary guidance: GMC — Confidentiality: main principles.
Scenario 3 — Medication error
You discover that a patient accidentally received twice the intended dose of a medication. The patient currently appears well.
What should you do first?
Show answer
Best answer: B
Why this is best: The immediate priority is the patient’s clinical safety. Reporting and candour matter, but neither should delay assessment and treatment of possible harm.
Principle tested: Patient safety · candour · prioritisation
Tempting distractor: A. Incident reporting is appropriate, but it is not the first action while patient harm may still need assessment.
What would change the answer? Once immediate clinical safety has been addressed, escalation, disclosure, documentation and incident reporting become priorities.
OSCE transfer: How would you explain the error openly to the patient after assessing them?
Primary guidance: GMC — Professional duty of candour.
Scenario 4 — Unsafe colleague
An FY1 notices that a registrar smells strongly of alcohol, appears unsteady and is about to perform an invasive procedure.
What should the FY1 do?
Show answer
Best answer: C
Why this is best: A credible immediate risk to patient safety requires prompt action. Professional hierarchy does not justify allowing a potentially impaired clinician to proceed while a patient may be harmed.
Principle tested: Patient safety · raising concerns · professionalism
Tempting distractor: A. Waiting preserves hierarchy but exposes the patient to the risk you are obliged to address.
What would change the answer? Without an immediate patient-facing risk, escalation may still be required, but the urgency and exact pathway could differ.
OSCE transfer: What exactly could you say to pause the procedure without making an unsupported public accusation?
Primary guidance: GMC — Raising a concern.
Scenario 5 — Young person seeking contraception
A mature 15-year-old asks for contraception and does not want her parents informed. She understands the advice and implications, is likely to continue sexual activity regardless, and there are no indicators of exploitation or abuse.
What is the most appropriate action?
Show answer
Best answer: C
Why this is best: Under current GMC guidance, contraceptive advice and treatment can be provided to a person under 16 without parental knowledge when the relevant understanding, welfare and best-interest criteria are satisfied and there is no separate safeguarding reason to disclose.
Principle tested: Young-person competence · confidentiality
Tempting distractor: B. “Under 16” does not automatically mean “parent must decide.”
What would change the answer? Evidence of coercion, exploitation, abuse, significant safeguarding risk or inability to understand the implications.
OSCE transfer: How would you encourage involvement of a trusted adult without making it a condition of care?
Primary guidance: GMC — Contraception, abortion and STIs.
Scenario 6 — DNACPR
A patient has a valid DNACPR decision. A junior colleague proposes stopping antibiotics, oxygen and analgesia because: “The patient is DNACPR.”
What is the correct response?
Show answer
Best answer: B
Why this is best: A DNACPR decision applies to cardiopulmonary resuscitation. It does not, by itself, mean that other clinically appropriate treatments or supportive care should be withheld.
Principle tested: End-of-life care · proportionality · treatment limitation
Tempting distractor: A. DNACPR does not mean “do not treat.”
What would change the answer? Another treatment could independently be judged inappropriate or not of overall benefit, but that requires its own decision.
OSCE transfer: How would you explain DNACPR to a relative who believes the team is “giving up”?
Primary guidance: GMC — Cardiopulmonary resuscitation.
From MCQ to OSCE Station
MCQs train one part of clinical ethics particularly well: deciding what should happen. An OSCE asks you to make that decision visible in a real interaction.
Stage 1Choose the best actionWhat should happen next?
Stage 2Explain whyWhy is it better than the closest alternative?
Stage 3Find the decision boundaryWhat fact would change the answer?
Stage 4Speak it aloudWhat would you actually say or do in the station?
For example, an SBA may establish that a capacitous patient’s informed refusal should be respected. The OSCE then tests whether you can explore why the patient wants to leave, explain the diagnosis and risk, check understanding and voluntariness, avoid coercion, safety-net, document and escalate appropriately.
After every ethics MCQ, ask: “What would I actually say next?”

How to Practise Ethics OSCE Stations Effectively
Attempt the decision before reading the explanation
Commit to one answer first. This distinguishes “I recognise the explanation” from “I can independently make the decision.”
Pay attention when two answers seem correct
Ask which action is correct now, which belongs later, and what additional fact would make the alternative correct. This is where much of the reasoning value lies.
Speak your answer aloud
Knowing “respect the patient’s informed refusal” is not enough. Practise saying it in patient-centred language, checking understanding, discussing risk without coercion and safety-netting.
Practise the difficult conversation, not just the rule
Rehearse telling a relative you cannot disclose information, explaining an error, challenging an unsafe senior, discussing DNACPR, or responding to treatment refusal.
Use the mark scheme after the attempt
Perform first, then compare your behaviour with the assessment criteria. This prevents passive checklist memorisation and makes feedback more diagnostic.

Frequently Asked Questions
What are common medical ethics OSCE stations?
Common scenarios involve consent, capacity, treatment refusal, confidentiality, safeguarding, children and young people, end-of-life decisions, duty of candour, professional boundaries and concerns about unsafe practice. The underlying task is usually to identify the professional problem, choose a safe next action and communicate appropriately.
How do you answer an ethics OSCE station?
Start with immediate safety. Then establish who can make the decision, understand the patient’s perspective, identify the relevant ethical or professional duty, decide what needs to happen next, and communicate, escalate and document appropriately.
How is capacity assessed in an OSCE?
Capacity relates to the specific decision at the specific time. Explore whether the patient can understand the relevant information, retain it sufficiently, use or weigh it when making the decision, and communicate their choice. Do not infer incapacity from diagnosis alone.
Can a patient refuse life-saving treatment in an OSCE scenario?
A competent adult can generally refuse offered treatment even when clinicians strongly recommend it and the consequences may be serious. In the station, demonstrate that the decision is informed and voluntary and that capacity has been appropriately considered rather than simply saying “autonomy.”
When can confidentiality be broken in an OSCE scenario?
Confidentiality is a strong professional duty but is not absolute. Disclosure may sometimes be required by law or justified by safeguarding or sufficiently serious risk of harm. The exact circumstances, purpose and minimum necessary disclosure matter.
Are medical ethics and law relevant to the MLA?
Yes. The current MLA Content Map explicitly includes medical ethics and law within areas of professional knowledge and links this to ethical duties in Good medical practice, detailed GMC guidance and legal responsibilities.
What is the best way to practise medical ethics for OSCEs?
Combine MCQs to decide what should happen, scenario rehearsal to practise what you would actually say, and timed OSCE station practice to make your reasoning visible under pressure. Review the rationale after committing to an answer, not before.
Put the Decision Into Practice
Ethics revision should not end when you identify the correct answer.
Could you recognise the dilemma, choose the safest next action and communicate it professionally with a real patient?
