Correct Answer: A

Rationale: Regular monitoring of blood glucose levels is crucial in managing diabetes and preventing complications. This allows the client and healthcare team to make timely adjustments to the treatment plan. While maintaining a low-fat diet, exercising regularly, and taking medication as prescribed are all important aspects of diabetes management, monitoring blood glucose levels takes precedence as it provides real-time information about the client's condition and helps prevent acute complications.

Correct Answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client's acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

Correct Answer: D

Rationale: Prompt and appropriate management of urinary retention prevents complications like infection and bladder damage.

Correct Answer: A

Rationale: In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.

Correct Answer: C

Rationale: The correct answer is to discontinue the IV infusion (Choice C). Pain and swelling at the IV site can indicate infiltration or phlebitis, which are serious complications that require immediate action. Slowing the rate of infusion (Choice A) may not address the underlying issue and can potentially worsen the condition. Applying a warm compress (Choice B) may provide temporary relief but does not address the need to discontinue the infusion. Elevating the affected arm (Choice D) is not the priority in this situation; discontinuing the infusion takes precedence to prevent further harm.
