Correct Answer: D

Rationale: The correct answer is D. A left extremity capillary refill greater than 5 seconds indicates poor blood flow to the extremity, which is a sign of compromised circulation. This finding requires immediate intervention by the nurse to prevent complications such as tissue damage or necrosis. Choices A, B, and C are important assessments but do not indicate an immediate need for intervention like the delayed capillary refill in choice D.

Correct Answer: D

Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.

Correct Answer: A

Rationale: The correct answer is A: 'Smokes 1.5 packs of cigarettes daily.' Smoking is a significant risk factor for peripheral arterial disease, a condition that can lead to intermittent claudication. The nicotine and other chemicals in cigarettes can damage blood vessels, leading to reduced blood flow and increased risk of developing circulation problems. Choices B, C, and D are less significant in the context of intermittent claudication. Regular exercise, a high-fat diet, and daily alcohol consumption may have health implications, but they are not as directly linked to the development of intermittent claudication in the presence of obesity, diabetes, and smoking.

Correct Answer: A

Rationale: The correct answer is A: Pain. The pain caused by Herpes Zoster (shingles) can disrupt sleep patterns. It is a common symptom of shingles and can lead to difficulty falling asleep or staying asleep. Nocturia (B), dyspnea (C), and frequent cough (D) are not typically associated with shingles and would not directly cause difficulty sleeping in this scenario.

Correct Answer: C

Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.
