Correct Answer: A

Rationale: The correct answer is to change the ostomy pouch every 4 to 7 days. This practice helps prevent skin irritation and leakage by maintaining a clean and secure seal around the stoma. Option B is incorrect because it is more important to change the pouch regularly rather than emptying it when half full. Option C is incorrect as applying a skin barrier is typically done during the initial application of the pouch, not during regular changes. Option D is incorrect because alcohol can be too harsh for the peristomal skin and can cause irritation.

Correct Answer: B

Rationale: The correct intervention for a client with pneumonia is to perform chest percussion every 4 hours. Chest percussion helps loosen secretions and improve airway clearance in clients with pneumonia. Placing the client in the supine position can worsen breathing, so it is incorrect. Administering oxygen via nasal cannula is a common intervention for clients with respiratory issues but is not specific to pneumonia. Limiting fluid intake to 1,500 mL/day may not be appropriate as pneumonia can lead to dehydration, so it is not the priority intervention.

Correct Answer: A

Rationale: The best dietary recommendation for a patient with chronic liver disease is a low protein diet. In liver disease, the liver may have difficulty processing protein, leading to the accumulation of toxins like ammonia in the body. A low protein diet helps reduce the burden on the liver and minimizes the production of these harmful substances. High protein diets can exacerbate the condition by increasing the workload on the liver. A low sodium diet (Choice C) is also important for liver disease patients as excess sodium can contribute to fluid retention and swelling, but reducing protein intake is the primary focus in these cases.

Correct Answer: A

Rationale: The most important nursing action when a patient has a central line is to monitor for infection. Central line-associated bloodstream infections are a serious complication that can lead to severe outcomes. Monitoring for infection involves assessing the patient for signs and symptoms such as fever, chills, and hypotension. While monitoring the central line dressing, redness, and swelling are also important aspects of care, they are secondary to monitoring for infection as the primary focus should be on preventing serious complications.

Correct Answer: A

Rationale: The correct answer is A: Educate the patient on the importance of medication. Providing education to the patient is crucial in promoting understanding of the condition and the necessity of medication. By enhancing the patient's knowledge, healthcare providers can empower them to make informed decisions regarding their health. Choice B, respecting the patient's decision, may not be appropriate in this scenario as untreated hypertension can lead to serious complications. Choice C, informing the healthcare provider, is important but should be done after attempting to educate the patient. Choice D, exploring alternative treatment options, may be considered if the patient has concerns or side effects related to the medication, but initially, educating the patient about the importance of medication is key.
