Correct Answer: C

Rationale: Choice C is the correct answer because clients with chronic renal failure should not skip dialysis sessions. Skipping dialysis can lead to serious complications and worsen the client's condition. It is crucial for clients to understand the importance of adhering to their dialysis schedule for optimal management of chronic renal failure. Choices A, B, and D are incorrect because they demonstrate understanding of fluid restrictions, the need to limit fluid intake to prevent overload, and the importance of medication compliance, respectively. These statements show appropriate knowledge and do not indicate a need for further teaching.

Correct Answer: D

Rationale: The correct answer is 'Increased venous pressure.' In peripheral vascular disease (PVD), impaired blood flow leads to increased venous pressure in the lower extremities, causing fluid to leak out of the blood vessels and accumulate as edema. Choice A, 'Competent venous valves,' is incorrect because in PVD, the venous valves may be incompetent, contributing to venous pooling and edema. Choice B, 'Decreased blood volume,' is incorrect as PVD is associated with impaired blood flow rather than reduced blood volume. Choice C, 'Increase in muscular activity,' is incorrect as it does not directly relate to the development of edema in PVD.

Correct Answer: C

Rationale: The correct answer is C: High levels of low-density lipoprotein (LDL) cholesterol. High levels of LDL cholesterol contribute to the development of atherosclerosis and peripheral vascular disease by being deposited in the blood vessel walls, leading to the formation of plaques that can obstruct blood flow. Choice A is incorrect as a low concentration of triglycerides is not typically associated with an increased risk of atherosclerosis or PVD. Choice B is incorrect as high levels of high-density lipoprotein (HDL) cholesterol are actually considered protective against atherosclerosis as it helps remove cholesterol from arteries. Choice D is incorrect as low levels of LDL cholesterol are not typically considered a risk factor for atherosclerosis or PVD.

Correct Answer: C

Rationale: Before transporting the client for whirlpool therapy to debride the burned area, the nurse should give a prescribed narcotic analgesic agent. This intervention is essential to manage pain effectively during the debridement process. Obtaining supplies to re-dress the burn area (Choice A) is important but not as immediate as providing pain relief. Verifying the client's signed consent form (Choice B) is necessary for procedures but does not address the client's immediate pain needs. Performing active range-of-motion exercises (Choice D) is not indicated before whirlpool therapy for debridement of burns and may cause further discomfort to the client.
