Correct Answer: D

Rationale: The correct answer is to remove the restraint (Choice D). Cyanosis of the toes, indicated by a light blue color, suggests impaired circulation. The priority action is to ensure proper circulation by removing the restraint to prevent further compromise. Choices A and B are not the immediate actions needed for cyanosis related to impaired circulation. Choice C, placing a blanket over the feet, does not address the underlying issue of impaired circulation and could delay appropriate intervention.

Correct Answer: B

Rationale: The correct answer is B: Check the tube placement before administering any medication. Before administering medication through a nasogastric tube, the nurse must first verify the tube's correct placement to ensure the medication reaches the stomach and to prevent complications such as aspiration. Options A, C, and D are incorrect because administering medication without confirming proper tube placement can lead to serious consequences for the client.

Correct Answer: B

Rationale: The correct answer is B because the patient with oxygen and a lighter on the bedside table is at immediate risk of fire. Oxygen promotes combustion, and having a lighter nearby poses a serious safety hazard. This situation requires urgent attention to prevent a potential disaster. Choices A, C, and D do not present immediate life-threatening risks compared to the patient with oxygen and a lighter nearby.

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.

Correct Answer: B

Rationale: The correct answer is to assess the patient's respiratory rate. When a patient is receiving opioids, it is crucial to monitor their respiratory rate as opioids can depress the respiratory system, leading to respiratory depression and potential respiratory failure. Monitoring blood pressure, oxygen saturation, and heart rate are important assessments as well, but the priority lies in assessing respiratory rate due to the risk of respiratory depression associated with opioid use.
