Correct Answer: B

Rationale: The correct answer is B because chest physiotherapy (CPT) helps reduce respiratory infections by loosening mucus in the lungs. Choice A is incorrect because coughing may temporarily increase during CPT treatments as mucus is being cleared. Choice C is incorrect because postural drainage is typically performed before meals. Choice D is incorrect because while CPT can help manage symptoms and improve lung function in COPD, it does not cure the disease.

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: The correct answer is D. Prednisone should never be stopped abruptly; it must be tapered down. Stopping it suddenly can lead to adrenal insufficiency. Choices A, B, and C are all potential side effects or considerations when taking prednisone and do not indicate a need for further teaching.

Correct Answer: B

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient presenting with chest pain as it helps dilate blood vessels, reduce chest pain, and improve oxygen supply to the heart. Obtaining a detailed medical history, conducting an ECG, or administering morphine sulfate are important steps in the assessment and treatment process but are secondary to the immediate need to address chest pain and potential cardiac ischemia.

Correct Answer: D

Rationale: The correct answer is D: Dysrhythmias. Straining while defecating can lead to dysrhythmias due to increased vagal stimulation. Choices A, B, and C are incorrect. Straining while defecating is not typically associated with causing diarrhea, gastric ulcers, or dilated pupils.
