Verified step by step guidance

Understand the importance of preoperative instructions: Before surgery, specific instructions are given to ensure the safety and effectiveness of the procedure. These instructions often include dietary restrictions, medication guidelines, and activity limitations.

Identify the common preoperative instruction related to eating and drinking: Patients are typically advised to refrain from eating or drinking for a certain period before surgery. This is known as fasting and is crucial to prevent complications such as aspiration during anesthesia.

Consider the rationale behind fasting: Fasting reduces the risk of stomach contents entering the lungs during surgery, which can cause serious complications. It is a standard practice to ensure the patient's stomach is empty.

Evaluate the other options: Consuming a high-protein meal, engaging in vigorous exercise, or taking a double dose of medications are not standard preoperative instructions and could potentially lead to complications or interfere with the surgery.

Conclude with the most likely instruction: Based on the standard preoperative practices, the nurse is most likely to instruct the client to refrain from eating or drinking for a specified period before the procedure to ensure safety during surgery.
