Informed consent and advance directives: the nurse's role
NCLEX-RN topic: Informed consent
- The provider explains the procedure and obtains consent.
- The nurse's witness signature only confirms that the client signed.
- If the client has questions or seems confused, call the provider back.
- Use a trained medical interpreter, never a family member.
- A DNR covers CPR only; family cannot override the client's DNR.
Key facts
- Valid informed consent is voluntary, given by a client with decision-making capacity who understands the terms, with no coercion.
- The provider explains the condition, the procedure, its risks and benefits, the alternatives, and the client's right to refuse or withdraw consent.
- The nurse's signature as witness confirms that the client signed the form; it does not mean the nurse explained the procedure.

- If the client has questions or does not understand, the nurse notifies the provider before the form is signed.
- Consent is not needed in an emergency when delay would cause harm; for a minor or a client who lacks capacity, a parent, guardian or surrogate decides.
- A living will lists treatments a client wants or refuses if incapacitated; a health care power of attorney names a person to decide, and it covers health care, not money.
- A DNR order is a provider's medical order about CPR only; the client may change their mind, and family cannot override a DNR the client requested.
Quick check1 question · 2 more at the end
The surgeon has explained a laparoscopic cholecystectomy to a client and asks the nurse to witness the consent form. Before signing, the client says, "I'm still not sure why they need to take my gallbladder out or what else I could do." What is the nurse's best action?
Correct answer: D.
Consent is valid only when the client understands the reason for the procedure, its risks and benefits, and the alternatives. Explaining the procedure is the provider's responsibility. When a client voices questions or a lack of understanding, the nurse advocates by holding the signing and asking the provider to return.
A Incorrect: explaining the procedure, its purpose and alternatives belongs to the provider, not the witnessing nurse.
B Incorrect: a prior explanation does not make consent informed if the client still does not understand it.
C Incorrect: this client is alert and able to decide; a family member signs only when the client lacks capacity or is a minor.
D Correct: the client does not yet understand the procedure or alternatives, so the provider must clarify before consent is signed.
Full lesson
Each part starts with its main idea. Open a part when you want the details.
The short answer: The provider explains a procedure and obtains informed consent: the condition, the procedure, risks, benefits and alternatives. The nurse often witnesses that the client signed, and calls the provider back if the client has questions or seems confused. Advance directives (a living will, a health care power of attorney) guide care only when the client can no longer decide.
1 What makes informed consent valid?Informed consent is valid only when a capable client agrees freely after real understanding. 1 min
Informed consent is valid only when a capable client agrees freely after real understanding. It protects the client's right to self-determination, meaning the right to accept or refuse care.
The provider must cover these points before the client decides:
- The health problem and the reason for the treatment
- What will happen during the procedure
- The risks, how likely they are, and the expected benefits
- Other options, including what happens if the client waits or declines
- The right to refuse or withdraw consent
Surgery, many complex procedures, and blood transfusions need written consent. Everyday nursing care, such as giving a bath or a medication, also needs the client's verbal or written agreement.
2 Who does what in the consent process?The provider explains and obtains consent, and the nurse witnesses and advocates. 1 min
The provider explains and obtains consent, and the nurse witnesses and advocates. Keep the two roles separate.
| Task | Who does it |
|---|---|
| Explain the procedure, risks, benefits and alternatives | Provider |
| Obtain consent for a medical procedure | Provider |
| Witness that the client signed the form | Often the nurse |
| Notice questions or confusion and call the provider back | Nurse |
| Check that a signed consent is on the chart before the procedure | Nurse |
The nurse's witness signature confirms only that this client signed the form. If the client asks basic questions or seems unsure, the nurse does not fill in the gaps. The nurse stops and asks the provider to return.
3 When can someone else consent, or no one at all?A surrogate consents when the client cannot, and an emergency can waive consent. 1 min
A surrogate consents when the client cannot, and an emergency can waive consent. For a minor or a client found to lack capacity, a parent, legal guardian or named health care agent signs.
In a true emergency, when delay would cause harm, treatment can go ahead without consent. For a client who speaks another language, use a trained medical interpreter. Family members should not translate, because terms may be lost or bad news held back.
4 How can a nurse spot a capacity problem?Formal capacity decisions belong to providers, but the nurse can raise the alarm. 1 min
Formal capacity decisions belong to providers, but the nurse can raise the alarm. Capacity is the ability to make a specific medical decision, and it can be temporary.
Cues that should make the nurse question capacity include:
- Cannot state a decision, or accepts or refuses everything without discussion
- Asks no questions about the treatment, or gives shifting reasons for refusing
- Hallucinations, agitation, swinging emotions, or intoxication
- A new inability to do activities of daily living
5 What are advance directives?Advance directives are written instructions that guide care once the client cannot speak for themselves. 1 min
Advance directives are written instructions that guide care once the client cannot speak for themselves. A federal law, the Patient Self-Determination Act, covers hospitals and long-term care facilities. They must tell adults about their right to accept or refuse treatment and to make advance directives.
- A living will lists treatments the client wants or refuses, such as CPR, a ventilator or tube feeding.
- A durable power of attorney for health care names an agent who decides as the client would have. It covers health care, not money.
- A do-not-resuscitate (DNR) order is a medical order the provider writes. It covers CPR only, not pain relief or other care.
No attorney is needed to make an advance directive, and the client can change it at any time. Family cannot override a DNR the client asked for.
6 What the nurse doesThe nurse asks about advance directives, documents the client's wishes and makes sure they shape the plan. 1 min
The nurse asks about advance directives, documents the client's wishes and makes sure they shape the plan. Before any procedure, the nurse confirms a signed consent is on the chart, watches for capacity cues and calls the provider for unanswered questions. When a client wants to make a directive, the nurse can refer them to a social worker or chaplain.
Common mistakes
The traps students fall into most. Read these before you practice.
Watch out: When the client has questions, the nurse calls the provider back, not explains the procedure personally.
Watch out: A health care power of attorney makes health care decisions, not financial ones.
Watch out: An advance directive takes effect when the client cannot decide, not while the client can still speak for themselves.
Watch out: A DNR order covers CPR only, not other treatments such as pain medicine, other medicines or nutrition.
Watch out: Use a trained medical interpreter for consent discussions, not a family member.
How to remember it
Memory hook: "Provider explains, nurse witnesses, client decides." Every consent question fits one of those three roles.
Self-check:
- List the five points a provider must cover before consent.
- Say what your witness signature does and does not mean.
- Explain how a living will differs from a health care power of attorney.
