A nurse generally cannot obtain informed consent for a medical procedure that a physician or surgeon will perform. That duty belongs to the practitioner doing the procedure, and courts have treated it as personal to that practitioner rather than something that can be handed off. Nurses do obtain their own consent for nursing interventions they perform, and nurse practitioners working independently obtain consent the same way a physician would. So the honest answer to whether a nurse can obtain informed consent is: it depends on who is performing the procedure and what the nurse’s role in it actually is.
Why the Duty Belongs to the Treating Practitioner
Informed consent is a conversation, not a signature. The physician, surgeon, or other licensed independent practitioner who will perform the procedure is the person who has to explain the diagnosis, the nature and purpose of the treatment, its risks and expected benefits, the available alternatives (including doing nothing), and the likely outcome without treatment. The AMA’s ethics guidance frames the process as a communication between the physician and the patient that ends in the patient’s authorization for a specific intervention.1AMA Code of Medical Ethics. Informed Consent
Courts have enforced this sharply. One state supreme court held that “a physician may not delegate to others his or her obligation to provide sufficient information in order to obtain a patient’s informed consent” and that the process “requires direct communication between physician and patient” involving “a back-and-forth, face-to-face exchange.”2Justia Law. Shinal v Toms MD That decision overturned earlier precedent that had allowed the disclosure to happen through intermediaries. It is one state’s ruling, but the principle it reinforces runs through informed consent law generally: the person about to intervene on the patient is the one who has to explain the intervention.
Three elements have to be present for the consent that results to be valid. Disclosure, covered above. Capacity, meaning the patient can understand the information, appreciate how it applies to their situation, and reason through the decision. And voluntariness, meaning the patient decides freely, without pressure or manipulation. A nurse cannot supply any of these elements on the physician’s behalf, because the nurse is not the one who will perform the procedure and does not carry the practitioner’s disclosure duty.
What Nurses Actually Do in the Consent Process
Calling the nurse’s role “supportive” undersells it. Nurses often catch the problems the physician’s conversation missed, and their formal and informal tasks in the consent process are what keep bad consents from turning into procedures.
The formal tasks include witnessing the patient’s signature on the consent form, which involves verifying the patient’s identity, confirming that the procedure listed matches what was discussed, and confirming the form bears the correct provider’s name. Nurses also document that the consent process occurred.3AORN. Important Considerations When Obtaining Informed Consent – Section: The Nurse’s Role in Informed Consent
The more consequential work is advocacy. In preoperative interviews, nurses often ask patients to describe in their own words what procedure they are scheduled for. It’s a comprehension check. If the patient hesitates, gives a vague answer, or describes something different from what is on the form, the nurse has found a gap that has to be closed before anyone picks up an instrument.3AORN. Important Considerations When Obtaining Informed Consent – Section: The Nurse’s Role in Informed Consent Nurses may reinforce or clarify what the physician already explained, but they do not introduce new clinical information about the procedure, and they do not substitute for the physician’s disclosure.
The critical obligation is knowing when to stop. If a nurse identifies that a patient doesn’t understand the procedure, still has unanswered questions, or appears to be consenting under pressure, the nurse has to notify the physician and hold the process until those concerns are resolved. The ANA’s Code of Ethics frames this as “partnering with patients to determine agreement or refusal in all care encounters” and requires nurses to be “attuned to relational consent in all contexts.”4American Nurses Association. Code of Ethics for Nurses Provision 3.2 Witnessing a signature while knowing the patient is confused or coerced does not fulfill that duty, regardless of what the physician says.
Where Nurses Get Into Trouble
Nurses sometimes assume that because they didn’t obtain consent, they carry no legal risk. That isn’t quite right. A nurse is typically expected to verify that a valid, signed consent form exists before a procedure begins. Letting a procedure move forward without that verification, or witnessing a signature when the patient clearly lacks understanding, can create liability for the nurse individually and for the facility.
The Joint Commission requires that informed consent discussions include specific disclosures — such as informing the patient when students or other practitioners may be involved in their care — and that these disclosures be documented.5Joint Commission. Informed Consent – Other Practitioners or Students Performing Procedures Nurses verifying consent are part of the safety net that catches gaps before they become lawsuits. The safer practice is always to pause and contact the physician when something seems off, even under time pressure. This is where most consent-related problems for nurses actually originate: not from doing something wrong, but from letting something incomplete slide.
Consent Nurses Do Obtain on Their Own
While nurses don’t obtain medical informed consent for procedures another practitioner performs, they obtain consent for nursing interventions constantly. Much of it is implied. When a patient extends an arm for a blood pressure reading or opens their mouth for oral medication, they are consenting through cooperation. No separate form or verbal exchange is needed for those routine interactions.
Explicit consent becomes important for more invasive nursing procedures. Inserting a nasogastric tube, performing wound care with specialized products, starting an IV line, or administering an enema all involve enough discomfort or risk that the nurse should explain what will happen, why it’s needed, what the alternatives are, and what the patient might feel. Nurses review potential risks and benefits of specific wound care products and discuss practical alternatives, including the consequences of refusing treatment.4American Nurses Association. Code of Ethics for Nurses Provision 3.2 The consent may be verbal or written depending on facility policy, but the conversation itself matters more than the documentation format.
This is the same logic that puts the physician in charge of surgical consent, applied to nursing work. The person performing the intervention is the person who explains it and obtains agreement. When the nurse is performing the intervention, the nurse is the right person for that job.
Nurse Practitioners as the Treating Practitioner
Nurse practitioners working in full practice authority states can diagnose, treat, and prescribe independently without physician oversight. In that role, the NP is the treating practitioner, and the informed consent duty belongs to them the same way it belongs to a physician performing a procedure. They aren’t assisting someone else’s consent process; they’re conducting their own.
In states that require physician collaboration or supervision for NPs, the picture gets murkier. The NP may perform procedures within their scope, but the supervising physician may retain ultimate responsibility for the consent process depending on state law and facility policy. Court rulings have emphasized that the personal interaction between the practitioner and the patient is essential for meeting the legal standard, which limits how far the consent duty can travel through a supervisory chain.2Justia Law. Shinal v Toms MD NPs practicing in any model should confirm their state’s rules on this point, because the answer genuinely varies.
Situations That Change Who Consents, Not Who Obtains It
Several common scenarios shift the question of who provides consent for the patient, but they do not shift who has the duty to obtain it. Nurses often see these first, so the distinction matters.
Emergencies
When a patient is unconscious or incapacitated and faces a life-threatening emergency, the law presumes consent under the theory of implied consent, on the reasoning that a reasonable person would want emergency treatment if they could ask. This allows physicians, nurses, and other providers to deliver stabilizing care without a signed form. The exception applies only when no one authorized to consent is available and the situation meets the jurisdiction’s definition of an emergency. It disappears entirely if the patient previously refused treatment through an advance directive or a clear verbal refusal before losing consciousness. Once the patient regains capacity or a surrogate becomes available, the normal consent process resumes for any ongoing or elective treatment.
Patients Who Cannot Decide for Themselves
When an adult patient lacks decision-making capacity and no advance directive names a healthcare proxy, most states default to next of kin in a statutory priority order — typically spouse or domestic partner, then adult child, parent, sibling, and sometimes others. For most treatment of a minor, a parent or legal guardian provides consent, though many states carve out exceptions for reproductive health, mental health, and substance abuse care, and some recognize a “mature minor” standard. The lists vary by state, and nurses and physicians should know their jurisdiction’s rules. In all of these situations the surrogate is the one who consents; the treating practitioner still has the duty to obtain that consent.
Refusal and Withdrawal
Informed consent includes the right to say no. A competent adult can refuse any treatment, even life-saving treatment, for any reason. The ANA’s Code of Ethics explicitly requires nurses to respect that right as part of the consent process.4American Nurses Association. Code of Ethics for Nurses Provision 3.2 When a patient refuses, the nurse should confirm the patient understands the consequences, document the refusal and the information provided, and notify the treating physician.
Consent can also be withdrawn after it has been given, including during a procedure, if the patient is conscious and has capacity. Someone who consented to surgery in the pre-op area can revoke that consent in the operating room. This puts nurses in a difficult position when a surgeon is ready to proceed and the patient suddenly expresses doubt. The correct response is to stop and address the concern, not to proceed on the theory that the form was already signed. A signed form reflects a moment in time; it does not override a conscious patient’s current refusal.
Language Access
Consent is meaningless if the patient can’t understand the language being spoken. Federal rules implementing Section 1557 of the Affordable Care Act require covered healthcare entities to provide qualified interpreters free of charge to patients with limited English proficiency, and to do so accurately, in a timely manner, and in a way that protects privacy and independent decision-making. The guidance specifically addresses treatment decisions: the interpreter must convey information so the patient fully understands the consequences of both consenting to and rejecting the proposed treatment, and must be able to interpret effectively, accurately, and impartially.6Department of Health and Human Services. Language Access Provisions of the Final Rule Implementing Section 1557 of the Affordable Care Act Using a family member or an untrained bilingual staff member does not meet this standard, even when it feels more convenient. Nurses who notice a language barrier during the consent process should arrange qualified interpreter services before the patient signs anything.
Telehealth
Telehealth visits add consent requirements on top of the standard elements. The provider typically has to explain how the virtual visit works, describe the limitations of remote care such as the inability to perform a physical examination, address how patient privacy will be maintained during the call, and document that the patient agrees to receive care virtually.7HHS Telehealth. Obtaining Informed Consent for Telebehavioral Health Many states require telehealth-specific consent to be obtained and documented separately from general treatment consent, though the exact rules vary. If another person will join the visit, that additional participant must also consent.
What Happens When Consent Fails
For the treating practitioner, getting consent wrong is a legal exposure in its own right, separate from the quality of the care delivered. Performing a procedure with no consent, or a procedure substantially different from what the patient agreed to, can support a battery claim. Obtaining a signature but failing to disclose material risks or alternatives is treated as negligence, and it can succeed even when the medical care itself was flawless. Documentation of the consent conversation, not just the signed form, is what protects the practitioner.
For nurses, the exposure looks different. The risk is less about obtaining consent improperly and more about failing to act when the process breaks down. Proceeding with a procedure after noticing that a patient seems confused, pressured, or uninformed shifts some responsibility onto the nurse. That is why the small procedural habits — verifying the form, checking the patient’s understanding, stopping when something is off, calling the physician back into the room — carry more weight than they look like they should.
