1. Which of the following best describes the role of insulin in the body?

Correct answer: B

Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.

2. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?

Correct answer: A

Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.

3. After a hip replacement surgery, a client is instructed to use an abduction pillow while in bed. What is the primary purpose of this device?

Correct answer: B

Rationale: The primary purpose of using an abduction pillow after hip replacement surgery is to prevent hip dislocation. The abduction pillow keeps the legs separated, which reduces the risk of hip dislocation by preventing excessive internal rotation and adduction of the hip joint. Choices A, C, and D are incorrect as the main goal of using the abduction pillow is to maintain proper positioning and stability of the hip joint to prevent dislocation, rather than addressing blood clots, circulation, or pain relief.

4. While turning and positioning a bedfast client, the PN observes that the client is dyspneic. Which action should the PN take first?

Correct answer: C

Rationale: Notifying the charge nurse promptly is the priority when a bedfast client is dyspneic. Dyspnea can indicate a serious problem that requires immediate assessment and intervention. Contacting the charge nurse ensures timely assistance and appropriate actions to address the client's condition. Applying a pulse oximeter or measuring blood pressure may provide valuable data, but the priority is prompt communication with the charge nurse to ensure quick intervention. Observing pressure areas, while important for overall client care, is not the most immediate action needed when a client is experiencing dyspnea.

5. After a laparoscopic cholecystectomy, what is the most important instruction the nurse should give the client regarding post-operative care at home?

Correct answer: C

Rationale: Monitoring the incision sites for signs of infection is crucial after a laparoscopic cholecystectomy. Infections can lead to serious complications if not detected early. While avoiding heavy lifting and following a low-fat diet are important aspects of recovery, monitoring for infection takes precedence as it directly impacts the client's immediate post-operative well-being. Therefore, option C is the correct answer as it addresses the most critical aspect of post-operative care.
