Correct Answer: B

Rationale: The correct answer is B: Discontinue the IV line. When a client reports pain and burning around the peripheral IV site, it indicates possible phlebitis, which is inflammation of the vein. The priority action is to discontinue the IV line to prevent further complications such as infection or thrombosis. Applying a warm compress (Choice A) may worsen the inflammation. Increasing the IV flow rate (Choice C) can exacerbate the symptoms and elevate the risk of complications. Elevating the limb (Choice D) may provide comfort, but it does not address the underlying issue of phlebitis. Therefore, the priority action is to discontinue the IV line.

Correct Answer: B

Rationale: The correct answer is to apply a moisture-retentive dressing. This promotes a moist wound environment, which is crucial for wound healing in clients with diabetes. Encouraging a high-protein diet may support overall health but is not directly related to wound healing. Daily wound irrigation can disrupt the wound healing process by removing necessary growth factors and cells. Applying an ice pack to the wound is contraindicated as it can impair circulation and delay wound healing.

Correct Answer: C

Rationale: The correct action for the nurse to take when administering medications through an NG tube is to dissolve each medication separately and flush with water between medications. This practice helps prevent interactions between medications and ensures that each medication is delivered effectively. Option A is incorrect as mixing all medications together can lead to chemical interactions or alter the effectiveness of the medications. Option B is incorrect because flushing the NG tube with air is not recommended and may cause harm. Option D is incorrect as administering all medications at the same time does not allow for proper absorption and interaction control.

Correct Answer: C

Rationale: In clients with dementia and difficulty communicating, using behavioral indicators such as agitation and restlessness is more reliable for assessing pain than relying on verbal self-report, pain scales, or observing facial expressions. Verbal self-report may not be possible due to communication challenges, pain scales may be difficult for the client to comprehend, and observing facial expressions alone may not provide a comprehensive assessment of pain in individuals with dementia.

Correct Answer: C

Rationale: The correct instruction for a client using a metered-dose inhaler (MDI) is to hold the inhaler 1-2 inches from the mouth. This distance allows for the proper delivery of the medication into the lungs. Choice A is incorrect because the duration of inhalation can vary depending on the medication, and 1 second may not be adequate. Choice B is incorrect as shaking the inhaler vigorously is not necessary for all MDIs and can lead to inaccurate dosing. Choice D is incorrect as the client should hold their breath for about 10 seconds after inhalation to allow the medication to deposit in the lungs.
