Correct Answer: B

Rationale: The correct answer is B: 'Increase physical activity to 150 minutes per week.' Increasing physical activity is essential for clients with CAD as it helps reduce the risk of cardiovascular events. Choice A is incorrect as red meat is high in saturated fats, which can be detrimental for CAD. Choice C is incorrect as foods high in fiber, such as fruits, vegetables, and whole grains, are beneficial for heart health. Choice D is incorrect as increasing sodium intake can lead to hypertension and worsen CAD.

Correct Answer: B

Rationale: The correct answer is B because inhaling deeply and slowly elevates the cylinder on the spirometer, promoting lung expansion. Choice A is incorrect as exhaling deeply before inhaling is not the correct technique for using an incentive spirometer. Choice C is incorrect as inhaling quickly through the spirometer does not promote optimal lung expansion. Choice D is incorrect as inhaling several short breaths does not facilitate the proper use of an incentive spirometer.

Correct Answer: A

Rationale: The correct answer is A. Viral infections typically last longer than bacterial infections. This is because viral infections often require the body's immune system to fight off the virus, leading to a longer duration of illness. Bacterial infections, on the other hand, often cause a rapid onset of symptoms due to the toxins produced by bacteria. Choice B is incorrect because not all bacterial infections cause high fever. Choice C is incorrect because rashes can be caused by both bacterial and viral infections, but not always. Choice D is incorrect because while some viral infections may cause a sudden onset of symptoms, it is not a key distinguishing factor between viral and bacterial infections.

Correct Answer: A

Rationale: Correct answer: The most appropriate management for a patient with congestive heart failure is to administer diuretics to help remove excess fluid and monitor fluid balance. Diuretics help reduce the workload on the heart and alleviate symptoms of fluid overload. Choice B is incorrect because patients with congestive heart failure are usually advised to limit sodium intake and carefully monitor fluid intake. Choice C is incorrect because although oxygen therapy may be necessary in certain cases, it is not the primary management for congestive heart failure. Pain relief is not a primary intervention for this condition. Choice D is incorrect because bronchodilators are not the first-line treatment for congestive heart failure. Encouraging mobility is important, but administering diuretics and monitoring fluid balance take precedence in managing this condition.

Correct Answer: A

Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.
