Nursing Elites

1. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

2. A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?

• A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
• B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
• C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
• D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.

Correct answer: D

Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.

3. After hospitalization for SIADH, a client develops pontine myelinolysis. Which intervention should the nurse implement first?

• A. Reorient the client to the room
• B. Place an eye patch on one eye
• C. Evaluate the client's ability to swallow
• D. Perform range of motion exercises

Correct answer: C

Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.

4. A client with a history of hypertension is admitted with a blood pressure of 220/120 mm Hg. What is the priority nursing action?

• A. Administer antihypertensive medication as prescribed.
• B. Place the client in a supine position.
• C. Obtain a detailed health history.
• D. Monitor urine output.

Correct answer: A

Rationale: Administering antihypertensive medication is the priority nursing action in this situation. The extremely high blood pressure of 220/120 mm Hg puts the client at risk of severe complications such as stroke, heart attack, or kidney damage. Lowering the blood pressure promptly is crucial to prevent these complications. Placing the client in a supine position or obtaining a detailed health history are not immediate actions needed to address the hypertensive crisis. Monitoring urine output, although important, is not the priority when the client's blood pressure is critically high.

5. In planning care for a postoperative client with hypovolemic shock, which problem is most important to include in the plan of care?

• A. Risk for infection.
• B. Risk for falls.
• C. Impaired skin integrity.
• D. Activity intolerance.

Correct answer: B

Rationale: The correct answer is B: Risk for falls. In a postoperative client with hypovolemic shock, the most crucial problem to address is the risk for falls. Hypovolemic shock can result in dizziness and weakness, making the client prone to falling. Preventing falls is essential to avoid further injury or complications. Choices A, C, and D are not the top priority in this scenario. While infection, impaired skin integrity, and activity intolerance are important concerns, preventing falls takes precedence due to the immediate risk of injury associated with hypovolemic shock.
