Client Rights, Advocacy and Informed Consent

Principles and Roles in Informed Consent

Informed consent represents the voluntary agreement of a competent individual to undergo a proposed treatment, surgery, or invasive procedure. At its foundation, this process honors the ethical principle of autonomy, which establishes each individual's right of self-determination in making personal healthcare decisions. A signed consent document is legally void if it is procured through coercion, duress, or misrepresentation by clinical staff or family members. Furthermore, signing a preprinted form is not the only way consent may be formally documented in clinical practice.

The provider obtaining informed consent, often the clinician performing the procedure, must provide the required clinical disclosures; the nurse has separate responsibilities to assess apparent capacity and understanding and to raise concerns before the procedure. This clinician must explain the procedure's indications, anticipated benefits, material risks, expected complications, and viable alternative therapies. The nurse must never provide the primary detailed explanation of surgical risks or alternative options to obtain consent. The nurse witnesses the client's signature and assesses for apparent decision-making capacity and signs of coercion or misunderstanding; witnessing does not certify legal competence or establish that the provider's consent discussion was adequate.

Nurses frequently encounter situations where a client voices uncertainty right before a procedure. If a client expresses lingering questions, confusion, or a lack of understanding regarding the planned intervention, the nurse must withhold the form and immediately notify the performing provider before the client signs. Additionally, the nurse must ensure that valid informed consent is obtained prior to administering any procedure-related medications that could impair cognitive abilities, such as sedating premedications. Notably, recent substance use or prescribed medications do not automatically invalidate consent; rather, the client's decision-making capacity must be carefully evaluated at the exact time consent is given.

When an individual withdraws consent, the nurse must act decisively. A client with decision-making capacity may withdraw consent before an intervention and may also withdraw it after an intervention begins, to the extent the withdrawal can be honored safely. If a client withdraws consent, the nurse should pause the planned intervention or further preparations, protect the client's safety, and promptly notify the performing provider; if an intervention has begun, the team must respond to the withdrawal as safely as possible.
