What is true about informed consent for a client with suspected mental illness?

• A. The nurse should obtain consent from the family if the patient is mentally ill.
• B. The patient retains the right to refuse treatment until competence is legally determined.
• C. Primary care providers can proceed without consent in emergencies.
• D. Informed consent is not required for experimental treatments.

Answer: (B)

Decision-making capacity is the key to understanding informed consent in mental health. Informed consent means the patient must be able to understand the treatment, its risks and benefits, alternatives, and make a voluntary choice. When a client is suspected to have a mental illness, capacity is considered on a decision-by-decision basis and is not automatically assumed to be absent.

The important point is that until a court legally determines incompetence, the patient retains the right to refuse treatment. If the patient is found incompetent, a legally authorized representative or guardian may give consent instead. This respects the patient’s autonomy while recognizing that a formal determination of capacity has been made.

In emergencies, there are provisions that permit treatment without consent if the patient cannot participate in decision-making and delaying treatment would cause harm, but this is a separate, specific exception and not the general rule for everyday care. Also, experimental treatments always require informed consent because they involve risks and uncertainties beyond standard care.

So, the statement that the patient retains the right to refuse treatment until competence is legally determined best reflects how consent and capacity are handled with suspected mental illness.
