In the United States, informed consent is a fundamental ethical and legal requirement for medical care. While physicians traditionally lead the consent process, nurses often play a critical role in ensuring patients understand their options and rights. The ability of a nurse to obtain informed consent depends on state law, the nurse’s scope of practice, supervision arrangements, and the clinical context. This article explores who can obtain informed consent, the nurse’s responsibilities, and best practices to protect patient autonomy and safety.
Who Can Obtain Informed Consent?
The primary responsibility for obtaining informed consent typically lies with the physician or other qualified practitioner who is performing a procedure or administering treatment. In many cases, a physician must discuss the nature of the procedure, risks, benefits, alternatives, and potential outcomes with the patient. However, a nurse may participate in the process by providing information, answering questions, clarifying misunderstandings, and confirming the patient’s comprehension. In some states, advanced practice registered nurses (APRNs) or physician assistants can obtain consent for their own procedures under defined supervision or independent authority.
Role of Nurses in the Consent Process
Nurses often serve as patient advocates and educators during informed consent. Their responsibilities include:
- Assessing the patient’s decisional capacity and confirming consent is voluntary.
- Providing clear, jargon-free explanations of the procedure, risks, benefits, and alternatives.
- Identifying and addressing language barriers, cultural considerations, and health literacy issues.
- Ensuring the patient has adequate time to deliberate and ask questions.
- Documenting the consent discussion and any questions or concerns raised by the patient.
- Communicating any changes in the procedure or new information to the patient and the care team.
Key takeaway: Nurses support informed consent without substituting for the primary consent authorizing clinician.
Legal and Ethical Considerations
Legal standards for informed consent vary by state but share core elements: disclosure of information, patient capacity, voluntary decision-making, and patient understanding. Ethically, respect for patient autonomy requires that a patient willingly agrees to or declines a treatment after being informed. Risks of improper consent include litigation, professional discipline, and compromised patient safety. Nurses must recognize and respect scope-of-practice boundaries and follow institutional policies, which may mandate that only specific professionals obtain consent for particular procedures.
When Nurses May Obtain Consent
Under certain circumstances, nurses may assist with or obtain informed consent, including:
- Delegated consent under a formal protocol or standing orders that authorize specific procedures.
- Consent for routine, non-invasive procedures where the physician has provided the core information and the nurse reinforces understanding.
- Emergencies where delaying treatment could harm the patient and there is no time to obtain a physician’s direct consent.
- When the nurse is a licensed practitioner (e.g., APRN) who has prescriptive authority or the ability to perform the procedure within their scope.
In all cases, the patient’s decisional capacity and voluntariness must be established, and documentation should reflect who provided the information and who obtained consent.
Documentation and Best Practices
Clear documentation is essential to demonstrate that informed consent was obtained properly. Best practices include:
- Recording the date, time, location, and persons present during the consent discussion.
- Summarizing the information provided, including risks, benefits, alternatives, and potential complications.
- Noting the patient’s questions and the nurse’s or clinician’s responses.
- Documenting the patient’s decisional capacity assessment and any use of interpreters or assistive devices.
- Storing consent forms in the medical record and ensuring they are legible and complete.
- Reassessing consent if new information arises or if the patient’s decision-making capacity changes.
Tip: When a nurse is involved, attach a brief note indicating their role in the discussion and the information they conveyed to support patient understanding.
Common Scenarios and Practical Considerations
Several everyday situations illustrate how consent may unfold in practice:
- A patient undergoing a minor surgical procedure with a physician performing the operation and the nurse supporting with explanations and verifying comprehension.
- An emergency where time-sensitive actions are needed; the clinician may proceed under presumed consent if immediate care is required and no surrogate is available.
- A patient with limited health literacy; the nurse uses teach-back strategies to confirm understanding before the physician proceeds with consent.
- A nurse practitioner performing a procedure under a protocol that explicitly authorizes consent and treatment without separate physician approval for that process.
In all instances, respect for patient autonomy, accurate information exchange, and proper documentation are essential.
Risks and Limitations
Missteps in the consent process can lead to legal exposure and patient harm. Risks include:
- Consent obtained without adequate understanding or for coercive reasons.
- Inadequate disclosure of risks, alternatives, or potential complications.
- Failure to recognize or document decisional incapacity.
- Breaches of confidentiality during the discussion.
To mitigate these risks, healthcare teams should review policies, ensure ongoing education about consent, and use interpreters or patient advocates when needed.
Practical Summary for Clinicians
For nurses and other clinicians, a practical framework can help ensure compliant and patient-centered consent:
- Know your state’s scope-of-practice laws and institutional policies regarding who can obtain consent for specific procedures.
- Always verify patient capacity and voluntariness before proceeding.
- Provide clear, unbiased information and check for understanding using teach-back techniques.
- Document comprehensively and promptly, including who conveyed information and who obtained consent.
- Coordinate with the supervising clinician to ensure the consent aligns with the planned intervention.
Bottom line: Nurses play a vital, permissible role in informed consent when aligned with legal frameworks, policy, and clinical context, always prioritizing patient autonomy and safety.
