Informed Consent

The surgeon explains the procedure, but the nurse witnesses the signature — if the client seems confused about what they agreed to, your next action determines whether that consent is legally valid.

Informed consent is a legal and ethical requirement before any invasive procedure, surgery, or high-risk treatment. The provider who will perform the procedure is responsible for explaining the diagnosis, proposed intervention, risks, benefits, alternatives, and consequences of refusal. The nurse's role is specific: verify that the consent form is signed, confirm the client understands what was explained, and witness the signature — not explain the procedure itself. Consent must be obtained while the client is competent, alert, and free from impairment. If the client has received sedating medications (opioids, benzodiazepines), consent obtained afterward is invalid. The client must be of legal age (18 in most jurisdictions) or an emancipated minor. Consent can be withdrawn at any time, even after signing, even in the OR holding area. In a true life-threatening emergency where the client cannot consent, implied consent allows treatment to proceed. If the client expresses uncertainty or asks new questions about the procedure, the nurse stops the process and notifies the provider to return and clarify — never re-explain risks or benefits on the provider's behalf.

Key Distinctions

The nurse witnesses consent; the provider obtains it. Students confuse these roles — if a client asks 'What are the risks?' the nurse contacts the provider, not answers independently. Don't confuse implied consent (unconscious trauma patient) with informed consent (alert, competent client). Consent signed after preoperative sedation is legally invalid, even if the client seems oriented.

Clinical Pearl

Think of the nurse as a notary, not a translator. You verify understanding and witness the signature — you never substitute for the provider's explanation.
