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: B

Rationale: The correct answer is to reduce caffeine and alcohol intake for a client with hypertension. Caffeine and alcohol can increase blood pressure, so reducing their intake can help manage hypertension. Increasing sodium intake (Choice A) is not recommended for hypertension as it can lead to fluid retention and increased blood pressure. Eating carbohydrate-rich meals (Choice C) is also not ideal as excessive carbohydrates can contribute to weight gain, which can worsen hypertension. Similarly, increasing protein intake (Choice D) is not a primary focus for managing hypertension unless a specific protein deficiency is present.

Correct Answer: C

Rationale: The correct answer is to keep oxygen tanks upright at all times. This is essential for safety as it prevents the tanks from falling and causing injury. Allowing the client to smoke in designated outdoor areas (Choice A) is unsafe as smoking near oxygen equipment can lead to a fire. Placing the oxygen equipment 10 feet away from any open flames (Choice B) is important to prevent fire hazards, but keeping the tanks upright is more directly related to preventing injuries. Restricting fluid intake while using oxygen (Choice D) is not necessary for safety in home oxygen therapy.

Correct Answer: C

Rationale: Irritability is an early indicator that suctioning is needed for a client with a tracheostomy because it can signal discomfort or difficulty breathing due to mucus accumulation, prompting the need for suctioning to clear the airway. Bradycardia (Choice A) and hypotension (Choice B) are not typically early indicators of the need for suctioning in a client with a tracheostomy. Confusion (Choice D) is also not a direct early indicator of the need for suctioning in this context.

Correct Answer: B

Rationale: The correct answer is B. Changing the TPN tubing every 24 hours is crucial in preventing infection by reducing the risk of bacterial contamination. Monitoring electrolyte levels (choice A) is essential but not directly related to preventing TPN-related infections. Monitoring blood glucose levels (choice C) is important for clients receiving TPN, but it is more related to glycemic control than infection prevention. Administering insulin as prescribed (choice D) is necessary for clients with diabetes but is not directly linked to preventing TPN-related infections.
