How does informed consent differ for minors or incapacitated patients in anesthesia?

• A. A parent or legal guardian or court-appointed surrogate provides consent; if the patient lacks capacity, surrogate decision-making applies.
• B. The patient must consent regardless of capacity.
• C. The consent is not required if anesthesia is routine.
• D. Only the nurse needs to obtain consent.

Answer: (A)

The main idea is that when someone is not able to make their own medical decisions, someone else must give the consent. For minors, a parent or legal guardian provides consent. For an incapacitated adult, a court-appointed surrogate or a designated decision-maker (such as a durable power of attorney for healthcare) step in to decide. If the patient has previously expressed their wishes or has an advance directive, the surrogate should follow those preferences; if not known, the surrogate should act in the patient’s best interests or use substituted judgment if possible. The anesthesia provider must ensure the surrogate understands the risks, benefits, alternatives, and potential consequences, and document the consent. In emergencies, consent may be implied to treat and prevent harm, but this is an exception rather than the rule.
