Correct Answer: B

Rationale: The correct answer is B: Administer a prescription for gabapentin. Gabapentin is used to treat phantom limb pain, which is common after amputations. Encouraging discussion about feelings of limb loss (choice A) is important for emotional support but does not address the physical pain. Teaching the client how to wrap the stump with an elastic bandage (choice C) is not indicated for aching in the 'right foot' as described. Offering assistance to move to a quiet room to relax (choice D) may provide comfort but does not address the underlying issue of phantom limb pain.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen via nasal cannula. Oxygen therapy is the priority intervention for a client with COPD experiencing increasing shortness of breath. It helps improve oxygenation and relieve respiratory distress. Choice B is not the priority as oxygenation needs to be addressed first. Choice C, chest physiotherapy, may be beneficial but is not the immediate priority in this situation. Choice D, encouraging the client to cough and deep breathe, is not the priority intervention when oxygenation is compromised.

Correct Answer: C

Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.

Correct Answer: B

Rationale: Phenytoin can cause gingival hyperplasia, so good oral hygiene is important to prevent complications.

Correct Answer: B

Rationale: The client with antisocial behavior being yelled at by peers may escalate the situation, potentially leading to violence or self-harm. Addressing the situation quickly helps prevent harm and de-escalates the conflict. Choices A, C, and D do not present immediate risks that require urgent intervention compared to the potential danger of a conflict escalating to violence with the client exhibiting antisocial behavior.
