A client undergoing surgery is being taught about the use of a patient-controlled analgesia (PCA) pump by a nurse. Which statement by the client indicates an understanding of the teaching?

Correct Answer: D

Rationale: The correct answer is D because clients should press the button on the PCA pump when they feel pain to receive controlled doses of medication. Option A is incorrect as the client should be the one to self-administer the medication through the PCA pump. Option B is incorrect as the primary purpose of the PCA pump is to manage pain, not to keep the client comfortable. Option C is incorrect because the client should not adjust the dosage themselves; instead, they should communicate any pain concerns to the healthcare provider.

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes that fit properly.' In peripheral arterial disease (PAD), it is crucial to wear shoes that fit well to prevent foot injuries. Choice A is incorrect because applying lotion between the toes can increase the risk of infection. Choice C is incorrect since walking barefoot at home can lead to injuries, especially in individuals with PAD. Choice D is incorrect as applying ice to the feet daily can further reduce blood flow to the extremities, worsening the condition in PAD.

Correct Answer: B

Rationale: Corrected Rationale: Monitoring blood glucose levels is crucial in clients receiving TPN because the solution has a high glucose content. This monitoring helps prevent hyperglycemia and allows for timely adjustments in the TPN formulation if needed. Monitoring the client's temperature (Choice A) is not directly related to TPN administration. Administering insulin (Choice C) should be based on blood glucose levels and the healthcare provider's orders; it is not a standard intervention for all clients on TPN. Monitoring daily fluid intake (Choice D) is important for overall fluid balance but is not as critical as monitoring blood glucose levels specifically for clients on TPN.

Correct Answer: C

Rationale: The correct answer is to instruct the client to use a soft toothbrush. Using a soft toothbrush helps prevent bleeding in clients receiving chemotherapy, who are at risk for mucositis. Encouraging the client to eat high-protein foods (Choice A) is important for overall health but not directly related to preventing infection. Encouraging the client to drink 2 liters of fluid daily (Choice B) is essential for hydration but does not specifically prevent infection. Instructing the client to use a mouthwash containing alcohol (Choice D) is contraindicated as alcohol-containing mouthwashes can cause irritation and dryness in the oral mucosa, increasing the risk of infection.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Stop exercising if pain occurs.' In peripheral arterial disease (PAD), it is crucial to avoid exercising to the point of pain as this may worsen the condition and lead to complications. Exercising to the point of pain can result in inadequate blood flow to the extremities, causing further damage. By stopping exercise if pain occurs, the client can prevent exacerbating their condition. Choices A, C, and D are incorrect because exercising to the point of pain, limiting exercise to once per week, and avoiding walking altogether are not recommended strategies for managing PAD and could potentially harm the client.
