Correct Answer: D

Rationale: The correct answer is to monitor the patient's protein intake closely. In patients with chronic kidney disease on a low-protein diet, monitoring protein intake is crucial to prevent complications such as malnutrition or inadequate nutrient intake. Encouraging small, frequent meals (Choice A) can be beneficial but is not the priority over monitoring protein intake. Monitoring intake and output (Choice B) is important but does not directly address the specific focus on protein intake. Educating the patient on the benefits of a low-protein diet (Choice C) is essential but not as immediate as monitoring the actual protein intake.

Correct Answer: B

Rationale: Before administering medications through a nasogastric tube, the nurse should administer them one after the other without flushing. Flushing the tube with water should be done before and after each medication to prevent any interactions and ensure each medication is delivered effectively. The correct answer is not to administer all medications at once (choice A) as this can lead to potential drug interactions. Crushing all medications and mixing them together (choice C) is incorrect as each medication should be given separately to maintain their individual efficacy. Administering medications in liquid form only (choice D) is limiting and may not be suitable for all types of medications that need to be administered.

Correct Answer: B

Rationale: In the case of a client with unstable blood pressure, the priority action for the nurse is to continuously monitor the client's vital signs. This allows for immediate detection of any fluctuations in blood pressure and timely intervention if necessary. Choice A, monitoring every two hours, may not provide real-time information needed for prompt intervention. Choices C and D suggest waiting for instructions from the healthcare provider, which could cause a delay in addressing the unstable blood pressure, potentially leading to adverse outcomes. Therefore, the most appropriate initial action is to continuously monitor the client's vital signs.

Correct Answer: C

Rationale: The correct answer is C. According to the gate control theory, meditation helps relieve pain by blocking pain impulses from coming through the gate in the central nervous system. Choice A is incorrect as meditation does not directly alter the chemical composition of pain neuroregulators. Choice B is incorrect because meditation does not stop the occurrence of pain stimuli. Choice D is incorrect as meditation does not open the gate but rather closes it to block pain impulses.

Correct Answer: C

Rationale: The correct answer is C: Teach the patient how to administer insulin. This action is crucial in promoting self-management and control of diabetes. By educating the patient on administering insulin, they can actively participate in their treatment plan. Monitoring blood sugar levels (choice A) is important but doesn't empower the patient to take direct action. Encouraging a diabetic meal plan (choice B) is beneficial but may not directly address the need for insulin administration. Teaching about the complications of diabetes (choice D) is essential but may not be as immediately impactful as teaching insulin administration for day-to-day management.
