Correct Answer: D

Rationale: The correct answer is D: 'Use diaphragmatic breathing to achieve better exhalation.' Diaphragmatic breathing is an essential intervention for clients with COPD as it helps improve exhalation and lung function, ultimately reducing symptoms over the long term. Option A is incorrect because high-flow oxygen during sleep is more relevant for clients with conditions like sleep apnea rather than COPD. Option B, 'Reduce risk factors for infection,' is important but not as specific to the long-term management of COPD as diaphragmatic breathing. Option C, 'Limit fluid intake to reduce secretions,' is not a recommended intervention for clients with COPD, as adequate hydration is crucial for maintaining respiratory health.

Correct Answer: B

Rationale: Correct! In right-sided congestive heart failure, jugular vein distention is a common finding due to the backup of blood in the systemic circulation. This results in increased venous pressure, leading to jugular vein distention. Choices A, C, and D are incorrect because decreased urinary output, pleural effusion, and bibasilar crackles are more commonly associated with other conditions such as kidney dysfunction, lung issues, and pulmonary edema.

Correct Answer: A

Rationale: An increase in urine output is a positive sign that the client's hydration status is improving. It indicates that the kidneys are functioning well and that fluid therapy is effective. Increased urine output helps to eliminate excess fluid and waste products from the body. Choices B, C, and D are incorrect. Feeling more thirsty (choice B) is a sign of dehydration, not improvement. A decrease in blood pressure (choice C) and an increase in heart rate (choice D) are not typically indicative of improving fluid status during IV fluid therapy for dehydration.

Correct Answer: B

Rationale: The correct answer is B. Using nitroglycerin as needed, every 5 minutes, up to 3 doses, is the appropriate management for angina at rest. This helps dilate blood vessels, improving blood flow to the heart. Choice A is incorrect because chest pain that persists at rest should be addressed immediately, not waiting for 30 minutes. Choice C is incorrect as avoiding physical activity is not a recommended approach during an angina episode. Choice D is incorrect because nitroglycerin should be used during chest pain episodes, not as a preventive measure before physical activity.

Correct Answer: A

Rationale: The correct answer is A: Limit sodium intake to reduce fluid retention. Limiting sodium intake is crucial for managing congestive heart failure (CHF) as it helps reduce fluid retention. Excess fluid retention can worsen CHF by increasing the workload on the heart. Choice B is incorrect because while protein is essential for overall health, it is not directly related to managing CHF. Choice C is incorrect because potassium, although important, is not the primary focus in managing CHF. Choice D is incorrect because increasing fluid intake can exacerbate fluid retention in CHF patients.
