Correct Answer: B

Rationale: Administering morphine for pain relief is crucial for postoperative clients following a cholecystectomy to manage pain effectively. Placing the client in a supine position may not be ideal as it can cause discomfort and hinder breathing. Applying a warm compress to the incision site can increase the risk of infection. Placing a pillow under the client's knees is not a priority intervention compared to pain management.

Correct Answer: B

Rationale: Administering an intermittent enteral feeding through a gastrostomy tube requires flushing the tube with 10 mL of sterile water before feeding. This action helps ensure patency and prevents clogging. Choice A is incorrect because flushing after feeding does not address the need for pre-feeding tube flushing. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height of the feeding bag above the abdomen is typically regulated by healthcare facility policies and is not a universal standard.

Correct Answer: C

Rationale: The correct answer is C: Tachypnea. When caring for a client with pneumonia, the nurse should expect tachypnea, which is rapid breathing. This occurs due to decreased oxygenation and lung function. Bradycardia (A) is not typically associated with pneumonia; instead, tachycardia may be present. Hypertension (B) is not a common manifestation of pneumonia; instead, hypotension may occur due to sepsis. Hypothermia (D) is not a typical finding in pneumonia; fever or an elevated temperature is more common.

Correct Answer: C

Rationale: The correct action the nurse should include in the care plan for a client receiving nitroprusside for severe hypertension is to limit light exposure to the infusion. Nitroprusside is light-sensitive, so it should be protected from light exposure to prevent degradation. Administering calcium gluconate at the bedside is not directly related to nitroprusside administration. Monitoring blood pressure every 2 hours is a good practice but is not specifically related to the administration of nitroprusside. Keeping the client on NPO status is not necessary solely based on receiving nitroprusside.

Correct Answer: B

Rationale: The correct answer is B. The client reporting feeling less anxious is a positive indication of effective treatment for a pulmonary embolism. This suggests that the client's condition is improving psychologically. Option A is incorrect because increased density in all lung fields on a chest x-ray may indicate unresolved issues related to the embolism. Option C is incorrect as diminished breath sounds bilaterally suggest a complication or worsening of the condition. Option D is incorrect as ABG results within normal range do not necessarily indicate effective treatment for a pulmonary embolism, as other complications may still be present.
