Final answer:
The nurse should administer preoperative medications as ordered, confirm important details during the time out and sign in, and avoid inappropriate actions like encouraging a high-fat meal, stopping medications without guidance, or withholding information.
Step-by-step explanation:
The nurse at a provider's office must take several steps when preparing a client for surgery, and the correct action among the options provided is: a) Administer preoperative medications as ordered. This includes administering prophylactic antibiotics within 60 minutes before the incision is made if necessary, based on the surgeon, nurse, and anesthesia professional's review. Before surgery, a time out is conducted by the entire team to confirm the patient's identity, surgical site, and procedure, review critical events, and ensure that all team members have been introduced by name and role. Before the induction of anesthesia, during what is known as the sign in, the nurse and an anesthesia professional confirm that essential elements such as patient identity, surgical site, and allergies are verified, and that the patient's consent is confirmed.
Encouraging a high-fat meal before surgery, advising the client to stop all medications immediately, and withholding information about the surgical procedure are not appropriate actions and could be detrimental to the patient's health and surgical outcome.
