Correct Answer: A

Rationale: Increased urinary output is a common finding in clients with diabetes mellitus due to hyperglycemia and osmotic diuresis. This results in the body trying to eliminate excess glucose through urine, leading to increased urinary frequency and volume. Weight gain is not typically associated with diabetes mellitus but may occur in poorly controlled cases due to increased calorie intake. Blurred vision is more commonly associated with acute complications like hyperglycemia or hypoglycemia. Diaphoresis, or excessive sweating, is not a typical finding in diabetes mellitus but can be seen in conditions like hypoglycemia.

Correct Answer: B

Rationale: An elevated WBC count 48 hours postoperatively may indicate an infection and should be reported to the provider. Choice A, a heart rate of 90/min, is within normal limits and not a concerning finding postoperatively. Choice C, urinary output of 75 mL in the past 4 hours, may indicate decreased renal perfusion, but an elevated WBC count is a more urgent finding. Choice D, a temperature of 37.8°C (100°F), which is slightly elevated, could be indicative of the body's normal response to surgery and is not as alarming as an elevated WBC count.

Correct Answer: D

Rationale: Verifying the client's tube placement is the priority before administering any enteral feeding. This step ensures that the tube is correctly positioned in the stomach or intestines, minimizing the risk of complications such as aspiration. Checking the residual volume, elevating the head of the bed, and flushing the tube are important steps but should occur after confirming the tube placement to ensure the feeding is delivered safely and effectively.

Correct Answer: A

Rationale: The correct answer is A. Taking omeprazole before meals is important as it improves the medication's effectiveness in reducing gastric acid production. Option B is incorrect as omeprazole should not be taken with antacids as it can interfere with its absorption. Option C is incorrect because omeprazole is usually recommended to be taken before breakfast, not at bedtime. Option D is incorrect as omeprazole is generally taken on an empty stomach, at least 1 hour before a meal.

Correct Answer: B

Rationale: Administering a PRN dose of morphine is the most appropriate action to manage postoperative pain in a client following a colon resection. Morphine is a potent analgesic commonly used to relieve moderate to severe pain, especially in postoperative settings. While assisting the client to change positions in bed, encouraging relaxation techniques, and offering a back massage can provide comfort and support, they may not be sufficient in managing the pain following a major surgical procedure like a colon resection. Therefore, the priority intervention for acute postoperative pain control in this scenario is to administer medication like morphine.
