A nurse is collecting a blood pressure reading from a client who is sitting in a chair. The nurse determines that the client's BP is 158/96 mmHg. Which of the following actions should the nurse take?

Correct Answer: C

Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.

Correct Answer: D

Rationale: The correct action is to change the TPN bag every 24 hours to reduce the risk of infection. Changing the TPN tubing every 72 hours (Choice B) may increase the risk of contamination. Monitoring the client's blood glucose level every 4 hours (Choice A) is important but not specific to TPN administration. Weighing the client daily (Choice C) is essential for monitoring fluid status but is not directly related to TPN administration.

Correct Answer: A

Rationale: The correct action for the nurse to take when a client has a new prescription for wrist restraints is to pad the client's wrists before applying the restraints. This is important to prevent skin breakdown and injury. Tying the restraints to the side rails of the bed (Choice B) is unsafe and can lead to potential harm for the client. Similarly, securing the restraints to the bed frame (Choice C) is not appropriate as it can restrict the client's movement and cause discomfort. Using a quick-release knot to tie the restraints (Choice D) is also incorrect as it may compromise the effectiveness of the restraints in ensuring client safety.

Correct Answer: B

Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.

Correct Answer: A

Rationale: The correct answer is A. Nasogastric suctioning can lead to hypovolemia due to the loss of gastric fluids. Chronic constipation and syndrome of inappropriate antidiuretic hormone (SIADH) are not typically associated with hypovolemia. A toxic dose of sodium bicarbonate antacids may lead to metabolic alkalosis, not hypovolemia.
