Correct Answer: C

Rationale: Upon noticing phlebitis at the IV site, the nurse should remove the IV catheter and restart it in another location. Phlebitis is inflammation of the vein, and leaving the IV catheter in place can lead to further complications such as infection. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider immediately (Choice B) is important, but the immediate action to prevent complications is to remove the IV catheter. Monitoring the site for signs of infection (Choice D) is necessary, but the priority action is to remove and reinsert the IV catheter to prevent worsening of the phlebitis.

Correct Answer: A

Rationale: The correct teaching point for a client with left-leg weakness learning to use a cane is to maintain two points of support on the ground at all times. This ensures stability and helps prevent falls. Choice B, using the cane on the weak side of the body, may lead to imbalance and decreased support. Choice C, advancing the cane a specific distance with each step, is not as crucial as maintaining two points of support. Choice D, advancing the cane and the strong leg simultaneously, may also compromise stability and support for the weak leg.

Correct Answer: D

Rationale: The correct answer is to replace the NG tube with a new one. When a client with an NG tube experiences nausea and decreased gastric secretions, it indicates a possible problem with the tube itself. Replacing the tube ensures proper functioning and can alleviate the symptoms. Increasing the suction pressure (Choice A) can worsen the client's condition. Turning the client onto their side (Choice B) may be helpful in some situations but does not address the underlying issue. Irrigating the NG tube with sterile water (Choice C) is not the priority and may not resolve the problem.

Correct Answer: B

Rationale: The correct answer is to check the client's capillary blood glucose level every 4 hours. Clients receiving TPN are at risk for hyperglycemia, so regular monitoring of blood glucose levels is essential to detect and manage hyperglycemia promptly. Administering TPN through a peripheral IV catheter (Choice A) is incorrect as TPN should be given through a central venous catheter to prevent complications. Heating the TPN solution to room temperature (Choice C) is unnecessary and not a standard practice. Weighing the client every 3 days (Choice D) is important for monitoring fluid status but is not the priority action when caring for a client receiving TPN.

Correct Answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This action helps stimulate voiding post-catheterization by promoting relaxation and providing sensory input. Assessing for bladder distention after 6 hours (Choice A) is important but not the immediate intervention needed for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not effectively address the issue of post-catheterization voiding difficulty. Restricting the client's intake of oral fluids (Choice C) is not appropriate and can lead to dehydration, which is not helpful in promoting voiding.
