A 19-year-old woman is brought to the ED by her flatmate after taking an overdose of paracetamol tablets two hours ago. She says she wants to die and is refusing all treatment, wanting to leave the department. How do you manage this situation?

Tips to guide your answer

- Paracetamol overdose is time-critical: N-acetylcysteine (NAC) is most effective within 8 hours

- Mental Capacity Act 2005: capacity is decision-specific, time-specific, and must be assessed formally (understand, retain, weigh up, communicate)

- A patient who has just taken a potentially fatal overdose and is expressing suicidal ideation may lack capacity for the specific decision to refuse life-saving treatment

- If capacity is lacking, treat in best interests under the Mental Capacity Act

How to approach this Emergency Medicine interview question

This ethics question is common in Emergency Medicine NHS interviews because it reveals how you think under interview pressure, not just what facts you can recall. Use "A 19-year-old woman is brought to the ED by her flatmate after taking an overdose of..." as the anchor for a concise answer with a clear opening, a clinical or professional structure, and a reflective close.

What the panel is testing

A strong ethics answer makes the competing duties visible. Name the principle or legal issue, then describe the practical steps you would take in the hospital: gather facts, assess capacity where relevant, seek advice, document, and protect the patient. For emergency medicine, keep the answer time-aware. Panels expect prioritisation, early senior involvement, concise handover, and awareness of department flow without losing sight of the individual patient.

Identify the ethical tension before jumping to a decision: capacity, consent, confidentiality, best interests, or law.
Use local policy and senior advice, and be explicit about safeguarding or immediate patient-safety concerns.
Balance respect for autonomy with professional duties, documentation, and clear communication.

How to structure your answer

For a ethics prompt, aim for a short opening sentence, then two or three evidence-led points, then a final reflection. If you use STAR, keep the result and reflection as strong as the situation. If it is a clinical scenario, say what you would do now, what you would do next, and how you would keep the patient safe while help is coming.

Open by naming the main issue in the question.
Give a structured response rather than a memorised script.
End with escalation, documentation, learning, or follow-up.

Common mistakes to avoid
