Correct Answer: D

Rationale: Corrected Question: When a client with heart failure is prescribed enalapril, monitoring for hyperkalemia is essential. Enalapril is an angiotensin-converting enzyme (ACE) inhibitor that can lead to an increase in potassium levels in the blood. This adverse effect can be serious and potentially life-threatening. Choices A, B, and C are incorrect because enalapril does not typically cause hypertension, hypokalemia, or hyperglycemia as adverse effects. It's essential for healthcare providers to be vigilant in monitoring potassium levels when clients are on ACE inhibitors like enalapril.

Correct Answer: D

Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.

Correct Answer: D

Rationale: The correct answer is D. Complications of diabetes mellitus that a nurse should monitor for include nephropathy and cardiovascular disease, in addition to diabetic ketoacidosis, hyperosmolar hyperglycemic state, neuropathy, and retinopathy. While choices A and C mention some complications of diabetes, they do not cover all the complications that a nurse should monitor for. Choice B is incorrect as it suggests selecting all options, which is not accurate.

Correct Answer: B

Rationale: The correct nursing interventions for a patient with pneumonia include monitoring lung sounds and respiratory rate to assess the effectiveness of treatment and the patient's respiratory status. Providing fluids and rest (Choice A) can be supportive measures but are not specific nursing interventions for pneumonia. Encouraging coughing and deep breathing exercises (Choice C) can be helpful for airway clearance but may not be appropriate for all patients with pneumonia. Administering antibiotics and providing oxygen therapy (Choice D) are medical interventions rather than nursing interventions.

Correct Answer: C

Rationale: The correct instruction the nurse should include is to advise the client to drink four to five glasses of water daily. Increasing water intake helps alleviate constipation by softening stool and increasing bowel movements. Choice A, increasing dietary intake of raw vegetables, can be helpful in preventing constipation but may not be sufficient as the sole intervention for someone already experiencing constipation. Choice B, limiting activity, can worsen constipation as physical activity helps stimulate bowel movements. Choice D, bearing down hard when defecating, can lead to other issues like hemorrhoids and should be avoided.
