Final answer:
The nurse should invite the surgeon to explain the risks and benefits of the surgery to the client before they sign the informed consent, ensuring that the client is fully informed and acknowledges understanding the procedure.
Step-by-step explanation:
Before witnessing the client's signing of the informed consent, the nurse should take action b. ask the surgeon to speak to the client for clarification. This is because providing a detailed explanation of the risks and benefits of the surgery is the responsibility of the surgeon, who has the comprehensive knowledge required to fully inform the patient.
The nurse plays an important role in facilitating this communication and ensuring that the patient feels confident in understanding the procedure before giving consent. It is essential that all team members, including the surgeon, anesthesia staff, and nursing staff, orally confirm critical elements of the patient's care and procedure details before the surgery begins.
