Correct Answer: A

Rationale: Corrected Rationale: Monitoring daily weight is the most accurate method to assess fluid balance in patients receiving diuretics. Changes in weight reflect changes in fluid balance, making it a sensitive indicator. Monitoring intake and output (choice B) is important but may not provide a complete picture of overall fluid balance. Checking for edema (choice C) is a late sign of fluid imbalance and may not be sensitive enough to detect subtle changes. Monitoring blood pressure (choice D) is relevant but may not directly reflect fluid balance as it can be influenced by various other factors.

Correct Answer: C

Rationale: The correct answer is C. Clients with type 1 diabetes should rotate injection sites within the same anatomical region to prevent lipodystrophy. Choice A is incorrect because blood glucose levels should be checked regularly, not only when feeling sick. Choice B is incorrect as injecting insulin in the same spot each time can lead to lipodystrophy. Choice D is incorrect as insulin injections are usually required based on meal schedules and blood glucose levels, not just when levels are above 200 mg/dL.

Correct Answer: A

Rationale: Checking for skin turgor is a reliable method to assess dehydration in patients. Skin turgor refers to the skin's elasticity and hydration status. When a healthcare professional gently pinches the skin on the back of the patient's hand or forearm, dehydration is indicated by the skin not snapping back immediately. Monitoring blood pressure (choice B) is important but is more indicative of cardiovascular status rather than dehydration specifically. Checking for dry mucous membranes (choice C) can be a sign of dehydration, but skin turgor is a more direct assessment. Monitoring urine output (choice D) is also essential but may not provide immediate feedback on hydration status as skin turgor does.

Correct Answer: C

Rationale: The correct answer is C: 'Wear compression stockings daily.' Wearing compression stockings is essential after knee surgery to prevent venous stasis and reduce the risk of blood clots. Choice A is incorrect as crossing legs when sitting can increase the risk of blood clots. Choice B is incorrect because performing range-of-motion exercises every 4 hours may not be suitable for all clients post total knee arthroplasty. Choice D is incorrect as applying heat to the incision site can increase the risk of infection.

Correct Answer: C

Rationale: The correct initial action when a patient presents with chest pain is to obtain an ECG. This helps assess the heart's electrical activity and determine the cause of chest pain. Administering aspirin or oxygen therapy may be necessary later based on the ECG findings, but obtaining an ECG is the priority to evaluate the cardiac status. Surgery preparation is not the initial action for chest pain and should only be considered after a thorough assessment.
