8 Medical Ethics Scenarios for Australian Practice

Practise 8 medical ethics scenarios with prompts, answer structures and the Australian guidance to name in exams and clinical interviews.

· updated

You’re on call, the registrar has just asked for a fast ethics opinion, and the room is already full of tension. A patient is refusing treatment, a family wants “everything done”, or a colleague is unsure whether a disclosure must be made. In medical ethics scenarios, strong answers do more than name autonomy, beneficence, non-maleficence and justice. They start with the facts, check capacity and risk, communicate respectfully, consult the right people, document the plan, and name the Australian guidance or local policy that applies.

That method matters because the legal and policy position can vary by state, territory and even by hospital network. A good answer shows that you know the general ethical principle, and also that you would verify the current jurisdiction-specific position before acting. In Australia that matters most where ethics meets consent, guardianship, reporting duties, open disclosure and research governance.

The national reference point for most of what follows is the Medical Board of Australia’s Good medical practice: a code of conduct for doctors in Australia. Section numbers below refer to that code.

The scenarios are written for practice, not memorisation. Use them to build a repeatable structure you can apply under pressure, whether you’re answering aloud in an interview, writing a short case response, or preparing for an objective structured clinical examination (OSCE — a circuit of timed, separately marked stations) style station.

1. Jehovah’s Witness Blood Transfusion Refusal

A refusal of blood in a life-threatening bleed is one of the clearest medical ethics scenarios because the conflict is immediate. The patient may be frightened, family members may be distressed, and the team may feel torn between preserving life and respecting refusal.

The first task is to confirm the refusal is informed and current. Ask what the patient understands about the likely consequences, what treatments they will accept, and whether they have a documented advance care directive or refusal card. The case usually turns on whether the patient has decision-making capacity at the time, and on what the hospital’s own patient blood management protocol offers as alternatives.

Practical rule: respect the refusal, but never treat it as a shortcut. Confirm capacity, confirm understanding, and confirm exactly which products or procedures the patient accepts.

A concise answer should cover these points:

In an obstetric or perioperative case the same structure applies, but the stakes can feel higher because more than one life may be in view. The key point is that you don’t abandon autonomy because the situation is dramatic, and you don’t stop thinking clinically either. If time permits, involve the hospital ethics service and follow the local blood management protocol, because practice varies between services.

2. Capacity Assessment and Refusal of Care

A refusal of care becomes an ethics problem in the formal sense when capacity is in doubt or the refusal appears unsafe. It comes up most often when mental illness, delirium, intoxication or cognitive decline may be affecting decision-making.

Start by separating diagnosis from capacity. A person with dementia, psychosis or intoxication may still have capacity for a specific decision, and a person without a psychiatric diagnosis may still lack it if they cannot understand or weigh the options. Describe a structured capacity assessment and what you would ask.

A clear framework for the answer

Australian capacity tests are set in state and territory law, but they share a common four-part shape. Victoria’s Medical Treatment Planning and Decisions Act 2016, for example, presumes an adult has capacity unless there is evidence otherwise, and asks whether the person can:

Name the Act that applies where you are working, because the wording and the substitute decision-making rules differ between jurisdictions.

An elderly patient with recurrent falls who refuses admission, or a young person with first-episode psychosis who refuses antipsychotic medication, shouldn’t be labelled “incapable” just because the team disagrees with them. The question is whether the decision meets the capacity test, not whether it’s convenient.

Document the trigger for concern, not just the conclusion. Show why capacity was questioned, what was assessed, and who was involved.

Family and carers can help with background, but they can’t override a competent adult’s decision. If capacity is uncertain, involve psychiatry, geriatric medicine or another senior clinician early, and check the guardianship law in your jurisdiction. For interview practice, clinical scenario question strategies are useful because this kind of station rewards structure as much as knowledge.

3. Confidentiality and Disclosure to Prevent Harm

A patient tells you they have a specific plan to seriously injure a named person, and asks you to keep it secret. Another patient discloses ongoing child abuse, while a third refuses to share contact details after testing positive for tuberculosis. Each scenario involves confidentiality, but the lawful response may differ.

Confidentiality supports trust, but it has limits. The code of conduct asks doctors to treat patient information as confidential and to share it consistent with privacy laws (section 4.4), and recognises release of information where it is required or permitted by law (section 4.2.3). Start by clarifying exactly what the patient said, then assess the risk rather than treating every alarming statement as equivalent. Ask about a target, method, timing, access to means, previous behaviour and the safety of any vulnerable person.

Your answer should cover three areas:

A parent’s admission of child abuse may trigger mandatory reporting. The exact duty depends on the jurisdiction and the concern involved, so name the relevant state or territory legislation rather than claiming one national rule. A tuberculosis case may instead involve public health requirements, isolation and contact tracing. Do not collapse that pathway into a violence-risk response.

A strong answer sounds like this: “I would explain the limits of confidentiality, assess urgency, seek consent to share information where safe, and disclose only what is necessary if protection or reporting requires it.” If warning the patient could increase danger, seek senior advice and act without delay. Involve the consultant, hospital legal service or ethics support when time allows.

Document the patient’s words, your risk assessment, the information shared, the people contacted and the timing. The final response should acknowledge that local policy may alter the process while keeping patient and public safety central.

4. Withdrawal and Withholding of Life-Sustaining Treatment

A patient with advanced cancer says, “I do not want more chemotherapy.” Their family insists that treatment must continue, while the clinical team questions whether it offers meaningful benefit. A good answer clarifies goals, capacity, treatment burden and lawful authority before recommending a plan.

The College of Intensive Care Medicine (CICM) and the Australian and New Zealand Intensive Care Society (ANZICS) state in their joint Statement on Withholding and Withdrawing Treatment (IC-14, last reviewed 2021) that withholding and withdrawing treatment are legally and ethically equivalent, and that decisions to withhold should follow the same principles and processes as decisions to withdraw. The ethical focus is whether treatment remains appropriate for this patient, not whether it has already begun.

Start with the patient’s wishes, prognosis and treatment goals. Ask whether the treatment is still achieving its intended purpose, whether its burdens now outweigh its benefits, and whether the patient has decision-making capacity. Check for an advance care directive and identify the appropriate substitute decision-maker if the patient cannot decide. The code of conduct is explicit that there is no duty to prolong life at all cost, and that patients have the right to refuse treatment or ask for it to be withdrawn (sections 4.13.4 and 4.13.5).

These questions apply to advanced dementia with family disagreement about resuscitation, motor neurone disease with possible future ventilation, and requests to continue life support when the treating team considers further intervention to be of no benefit. Explain the clinical reasoning in plain language, acknowledge uncertainty, and offer comfort-focused care where appropriate.

A strong response covers:

Advance care directive frameworks and substitute decision-making rules are set by each state and territory, so confirm the ones that apply, along with local policy. Palliative care, senior nursing staff, social work and, where relevant, chaplaincy can support the discussion. Genuine unresolved conflict may need an ethics committee, a senior clinician, the hospital legal service or a local dispute-resolution pathway.

Withdrawing treatment is not assisting suicide. The same CICM and ANZICS statement records that when death follows withholding or withdrawal in line with its principles, the cause of death is the underlying medical condition. Symptom relief, nursing care and humane support continue. Document the reasoning, participants, decisions and review plan. OSCE-style practice helps you rehearse a calm explanation rather than relying on a dramatic conclusion.

5. Conflicts of Interest and Professional Boundaries

A surgeon receives speaker fees from an implant manufacturer and recommends that company’s device to a patient. The recommendation may be clinically defensible, yet the financial relationship still creates a conflict. Directing referrals to a family member’s business raises the same concern. The question tests whether you can recognise divided loyalty and protect independent, patient-centred judgement.

The code of conduct (section 10.12) asks doctors to recognise potential conflicts, act in patients’ best interests when referring, tell patients when they have an interest that could affect their care, and decline inducements of more than trivial value. A strong answer covers:

Use these distinctions in your reasoning:

Disclosure alone does not make every arrangement acceptable. The patient needs enough information to make an informed choice, and consent must be free from pressure. A patient may reasonably prefer another surgeon if a device recommendation is linked to industry payments.

Boundary concerns are different, and stricter. A romantic or sexual relationship with a current patient is not a conflict to be disclosed and managed: the Medical Board of Australia’s Sexual boundaries in the doctor-patient relationship guidelines (issued December 2018) state that it is never appropriate. Where a doctor notices warning signs, the guidelines direct them to seek advice from an experienced colleague or their indemnity insurer and, if objectivity could be compromised, to transfer the patient’s care to another doctor.

A concise viva answer on a financial conflict could be:

If the patient might reasonably doubt my independence, I would disclose the conflict, document it, and consider an independent clinician or stepping aside.

6. Allocating Scarce Resources

Two patients need the last available intensive care unit (ICU) bed. One has greater immediate urgency; the other has a better predicted chance of recovery. Your task is not to invent a personal rule under pressure. It is to explain how a fair decision should be made and who has authority to make it.

Resource allocation tests justice because demand may exceed available beds, medication, theatre time or staff. First identify the decision level. A bedside choice, such as ICU admission, differs from an institutional policy about rationing theatre capacity or an expensive treatment. Clinicians should apply the approved process and seek senior or ethics support when the policy is unclear.

Use the ethical frameworks as lenses rather than competing scripts:

Then state the practical safeguard: decisions should use clinical criteria, including prognosis, reversibility, urgency and likely benefit, rather than protected attributes. Age alone, disability alone or perceived social worth should not determine access. If an older patient has a poorer prognosis and a younger patient a greater predicted benefit, age is not the complete analysis. The team must apply the relevant criteria consistently and avoid assumptions about either patient.

A clear explanation matters to patients, families and staff. The health service should be able to describe the criteria and review pathway without implying that an individual clinician has unlimited discretion. The exact process differs between states, territories, hospitals and clinical services, so check the local policy, escalation pathway and documentation requirements.

Resource scarcity can also signal a system problem. Clinicians should raise repeated pressures through the appropriate service or governance channel.

A concise viva response is:

I would follow the approved policy, compare both patients using the same clinical criteria, escalate uncertainty to the senior team or ethics service, explain the reasoning, and document the decision.

That structure shows fairness, accountability and practical reasoning without pretending that one ethical theory resolves every case.

7. Disclosure of Error and Management of Adverse Events

An error that isn’t disclosed properly can become a bigger ethical problem than the original mistake. Open disclosure, patient safety and professional honesty are all in play.

The first step is to separate the event from the person. A wrong-dose medication error, an incorrect implant, a missed cancer on imaging or a communication failure all need prompt review. The code of conduct (section 4.11) asks doctors to recognise what has happened, explain it to the patient as promptly and fully as possible, acknowledge the patient’s distress and provide support, and follow the relevant open disclosure, review and reporting processes. Concealment usually deepens harm, because patients often feel betrayed once the truth comes out.

What a strong answer includes

A useful distinction is between error and misconduct. Not every error means a report to the regulator is required, but serious conduct or reportable events may trigger further obligations. Name the local open disclosure policy that applies.

If the issue arose from a system failure, say so. If a note was inaccurate or misleading, acknowledge that too. Patients respond better to transparent explanation than to polished excuses. Clinicians sometimes fear that disclosure automatically means punishment, but ethical practice is about accountability and repair, not self-protection.

Practical rule: if you’re tempted to wait because the patient “doesn’t need to know yet”, pause. Delayed disclosure usually increases distress and damages trust.

The best answers end with a commitment to safe follow-up and a review of how the same mistake can be prevented.

Research recruitment is different from treatment, and that difference has to be clear, especially when the participant is vulnerable or when a clinician is both doctor and investigator.

The ethical centre is informed, voluntary consent. A patient offered an experimental oncology therapy may assume the study is guaranteed to help them, but that’s therapeutic misconception, not understanding. The correct response is to explain that the study is research, not a treatment chosen purely for that person’s benefit.

A clean answer structure

Start with the governance question, then move to the consent question.

If the study involves a patient with impaired decision-making capacity, mention substitute decision-making or other approved safeguards, depending on the protocol and jurisdiction. If the project involves sensitive topics such as sexual health or psychiatric symptoms, privacy and data handling need explicit attention.

A good interviewer will also listen for whether you can separate clinical care from research recruitment. If the treating doctor is also the researcher, that relationship can create pressure, even if unintended. Acknowledge the conflict and describe how the patient’s right to decline would be protected.

The core sentence is simple.

This is a research study, not treatment specifically chosen for you.

That line directly addresses the misconception without sounding cold or legalistic.

Turn Each Scenario Into a Repeatable Answer

The fastest way to improve with medical ethics scenarios is to use the same structure every time. First, identify the immediate clinical risk. Then clarify the patient’s wishes, capacity and the relevant facts. Next, name the competing duties, communicate with empathy, consider less restrictive and safer alternatives, seek senior or multidisciplinary input, follow current Australian and local policy, and document the decision clearly.

That sequence works because it shows more than a named principle. It shows you can judge risk, recognise uncertainty, protect the patient and work within the system.

A useful revision routine is to practise aloud with timed prompts. Take one scenario, give yourself a minute to think, then answer in a short, structured way. After each attempt, check whether you covered the facts, the ethical conflict, the capacity or consent issue, the immediate safety step, the escalation pathway and the documentation plan. If you can do that consistently, you’ll sound more composed even when the details change.

Australian variation matters throughout. Consent rules, guardianship pathways, reporting obligations and end-of-life processes differ by state, territory and hospital network, so the best candidates never pretend there’s one universal answer. They show they know the general principle, then name the local check they’d make before acting. If you’re preparing for a selection interview rather than an exam, the format differs by college and by year; our guide to specialty selection interviews in Australia sets out who interviews and how.
