Final answer:
The nurse's signature on a surgical consent form has legal implications including confirming voluntary informed consent, documenting compliance, and providing legal protection.
Step-by-step explanation:
When a nurse signs a surgical consent form as a witness after a client has signed it, there are several legal implications. First, the nurse's signature confirms that the client voluntarily gave informed consent for the surgery, meaning they understand the risks and benefits of the procedure. Second, the nurse's signature serves as documentation that the consent process was conducted in compliance with legal and ethical standards. Finally, the nurse's signature may provide legal protection to both the client and the healthcare facility in case of any legal disputes related to the surgery.
