Consent

NCLEX items rarely ask you to define consent; they hand you a scenario and make you pick who does what. The trap answer is the nurse explaining the surgery — wrong, because disclosing the procedure, risks, and alternatives is the provider’s non-delegable duty (a nurse may help get the form signed, but cannot supply the explanation). The highest-yield “tell” is consent that is invalid: a sedated or premedicated client cannot give valid consent (give the pre-op opioid or benzodiazepine after the form is signed, never before), and a minor or cognitively incapacitated client needs a surrogate. In a true emergency, treatment may proceed under implied consent when delay threatens life or limb and the client cannot consent.

Do not confuse consent with autonomy — the underlying right of a competent client to decide, including informed refusal — or with advance directives, which activate only once the client cannot decide. A signed form is documentation, not the duty; your advocacy role is to halt the case the moment understanding is missing.
