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: A

Rationale: Corrected Rationale: The correct strategy for the nurse to encourage the postoperative client to ambulate is to explain the benefits of ambulation for recovery. Educating the client on how ambulation aids in preventing complications and promotes faster recovery can motivate their participation. Choice B is incorrect because waiting for the client to request to walk may lead to delays in mobilization. Choice C is incorrect as it may induce unnecessary fear in the client. Choice D is incorrect as offering pain medication before walking does not address the client's reluctance to ambulate.

Correct Answer: D

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

Correct Answer: A

Rationale: A follow-up with a healthcare provider is necessary to assess and manage the newly identified hypertension. While dietary changes and exercise are important for managing high blood pressure, immediate lifestyle modifications without further evaluation by a healthcare provider may not be safe or effective. Option A is the most appropriate initial step to ensure proper assessment and management of the client's blood pressure. Therefore, choices B and C are incorrect in this scenario. Option D is also incorrect because not all options should be implemented without proper medical guidance.

Correct Answer: B

Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
