Nursing Elites

1. What is the primary action of insulin in the body?

• A. To lower blood pressure.
• B. To promote the absorption of glucose into cells.
• C. To increase blood glucose levels.
• D. To decrease blood glucose levels.

Correct answer: B

Rationale: The correct answer is B: To promote the absorption of glucose into cells. Insulin facilitates the uptake of glucose by cells, thereby decreasing blood glucose levels. Choice A is incorrect as insulin does not directly affect blood pressure. Choice C is inaccurate as insulin works to lower, not increase, blood glucose levels. Choice D is incorrect because insulin's primary role is to lower, not increase, blood glucose levels by promoting glucose uptake into cells.

2. The client with chronic renal failure is receiving education on managing fluid intake. Which of the following statements by the client indicates a need for further teaching?

• A. I can drink as much water as I want.
• B. I should increase my intake of high-sodium foods.
• C. I can skip a dialysis session if I feel tired.
• D. I can eat whatever I want as long as I take my medications.

Correct answer: C

Rationale: Choice C is the correct answer. Clients with chronic renal failure should not skip dialysis sessions, as this can lead to serious complications. Dialysis is crucial for managing fluid and electrolyte balance in these clients. Choice A is incorrect because clients with renal failure often have fluid restrictions. Choice B is incorrect as high-sodium foods can worsen fluid retention in clients with renal failure. Choice D is incorrect because dietary restrictions are important in managing chronic renal failure, and eating whatever one wants can lead to further complications.

3. A client with Diabetes Insipidus (DI) is being cared for by a nurse. Which data warrants the most immediate intervention by the nurse?

• A. Serum sodium of 185 mEq/L (185 mmol/L)
• B. Dry skin with poor skin turgor
• C. Apical rate of 110 beats per minute
• D. Polyuria and excessive thirst

Correct answer: A

Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.

4. To help minimize the risk of postoperative respiratory complications after a hypophysectomy, during preoperative teaching, the nurse should instruct the client how to:

• A. Use incentive spirometry.
• B. Turn in bed.
• C. Take deep breaths.
• D. Cough.

Correct answer: C

Rationale: The correct answer is to instruct the client on how to take deep breaths. Deep breathing exercises are essential in preventing postoperative respiratory complications like atelectasis by promoting lung expansion. Using incentive spirometry is a more specific and advanced method of promoting deep breathing and lung expansion, making it a better choice than just turning in bed. While turning in bed may help with overall comfort and positioning, it is not as directly related to respiratory complications as deep breathing exercises. Coughing, although important for clearing secretions, is not as effective in preventing atelectasis as deep breathing exercises.

5. The nurse is caring for a client who is postoperative for a femoral head fracture repair. Which intervention(s) should the nurse plan to administer for deep vein thrombosis prophylaxis?

• A. Pneumatic compression devices
• B. Incentive spirometry
• C. Assisted ambulation
• D. Calf-pump exercises

Correct answer: A

Rationale: The correct intervention for deep vein thrombosis prophylaxis in a postoperative client with a femoral head fracture repair is the use of pneumatic compression devices. These devices help prevent stasis in the lower extremities by promoting venous return through intermittent compression. Incentive spirometry is used to prevent respiratory complications by promoting lung expansion and clearing secretions, not for DVT prophylaxis. Assisted ambulation and calf-pump exercises are beneficial for promoting circulation and preventing DVT, but pneumatic compression devices are more effective in this specific postoperative scenario.
