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: A

Rationale: The correct answer is to encourage early ambulation and leg exercises. By promoting early ambulation and leg exercises, blood flow is enhanced, reducing the risk of venous thromboembolism (VTE) in postoperative patients. Choice B, applying compression stockings, helps prevent VTE but is not as effective as early ambulation and exercises. Choice C, administering anticoagulants, is important in VTE prevention but does not directly address improving circulation through physical activity. Choice D, elevating the patient's legs, may be beneficial for circulation in specific cases but is not as effective in preventing VTE as early ambulation and leg exercises.

Correct Answer: B

Rationale: The correct first step for the nurse manager is to notify the hospital's safety committee. This action is crucial to ensure that the appropriate measures are taken promptly to address the non-compliance with safety protocols. Confronting the nurse directly may not be the best initial approach as involving the safety committee can provide a systematic and comprehensive response to the issue. Documenting the observation without addressing it or following up at a later time may delay the necessary actions to maintain a safe environment, making these choices less effective as the first course of action.

Correct Answer: B

Rationale: The correct answer is to recheck the blood pressure before calling for help. When caring for a client with unstable blood pressure, the nurse's priority is to ensure an accurate assessment. Rechecking the blood pressure will confirm the instability and guide further actions. Asking the charge nurse for assistance (Choice A) is important but should come after assessing the situation. Monitoring the client's blood pressure closely (Choice C) is essential, but the immediate action should be to recheck and confirm the current status. Administering antihypertensive medication immediately (Choice D) without a confirmed assessment can be dangerous and is not the initial priority.

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.
