Correct Answer: B

Rationale: The correct answer is to instruct the client to sit quietly for 5 minutes before taking their blood pressure. This is important because sitting quietly helps stabilize the heart rate, leading to a more accurate reading. Choice A is incorrect because taking blood pressure after eating can affect the readings. Choice C is wrong because using a blood pressure cuff that is too small can provide inaccurate readings. Choice D is also incorrect as blood pressure should be taken in a seated position for accurate results.

Correct Answer: B

Rationale: The priority when managing a client with a chest tube postoperatively is to check for air leaks and ensure the proper functioning of the chest tube. This is crucial to prevent complications such as pneumothorax or hemothorax. Clamping the chest tube intermittently can lead to a buildup of pressure in the pleural space and should not be done without a specific medical indication. Encouraging deep breathing and coughing helps with lung expansion but is not the priority over ensuring the chest tube's proper function. Encouraging frequent coughing may increase the risk of dislodging the chest tube or causing complications.

Correct Answer: B

Rationale: The correct first action for a client with a tracheostomy exhibiting signs of respiratory distress is to suction the tracheostomy. This helps clear the airway and improve breathing. Increasing the suction setting on the ventilator is not appropriate as the issue may be related to secretions that need to be directly removed. Notifying the physician should come after providing immediate nursing interventions. Encouraging deep breathing exercises is not suitable when the client is in respiratory distress and needs prompt intervention.

Correct Answer: D

Rationale: Checking the client's neurovascular status is the priority when caring for a client with severe pain after a leg fracture. This assessment is crucial to identify any signs of vascular compromise or nerve damage, such as compartment syndrome. Administering pain medication can help alleviate the pain but should only be done after ensuring the client's neurovascular status is stable. Repositioning or elevating the leg may worsen the condition if there are underlying vascular issues, making these options lower in priority than assessing neurovascular status.

Correct Answer: C

Rationale: When dealing with a physically assaultive client, the initial priority is to focus on restoring the client's self-control and preventing further escalation. Restricting the client to the room (choice A) may escalate the situation and is not the initial priority. Placing the client under one-to-one supervision (choice B) is important but comes after ensuring the client's self-control. Clearing the immediate area of other clients (choice D) is essential for safety but is not the initial priority when compared to restoring the client's self-control.
