Correct Answer: A

Rationale: The correct answer is A: 'Two to three soft bowel movements per day.' Lactulose is prescribed to produce soft, regular bowel movements to reduce ammonia levels in clients with cirrhosis. This helps in preventing hepatic encephalopathy. Option B is incorrect because increased serum ammonia levels would indicate that lactulose is not effectively reducing ammonia levels. Option C is incorrect because lactulose does not directly affect white blood cell counts. Option D is incorrect because soft, formed stools twice a day may not be frequent enough to effectively reduce ammonia levels in clients with cirrhosis.

Correct Answer: A

Rationale: In a client post-op with low urinary output, the first action the nurse should take is to assess the client's vital signs. Vital signs can provide valuable information about the client's overall condition, fluid status, and potential complications. Assessing the vital signs can help the nurse to determine if the low urine output is indicative of a larger issue that needs immediate attention. Irrigating the catheter with normal saline may be necessary but should not be the first action without assessing the client. Notifying the healthcare provider should follow assessment if there are concerns. Replacing the catheter with a larger size is not indicated solely based on low urinary output and should not be the first action taken.

Correct Answer: C

Rationale: A weight gain of 2 pounds in 24 hours is concerning as it indicates fluid retention, a potential complication of TPN leading to fluid overload. Elevated blood glucose levels (Choice A) are expected in TPN, serum potassium levels (Choice B) are within the normal range, and a white blood cell count (Choice D) of 7000/mm3 is also normal. Therefore, the correct answer is C, as it suggests a complication related to TPN.

Correct Answer: A

Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.
