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: A

Rationale: The correct answer is A: 'Has everyone at home already had varicella?' Herpes zoster (shingles) is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. By knowing if others at home had varicella (chickenpox), the nurse can assess the risk of transmission and provide appropriate guidance. Choice B is incorrect because antifungal creams are not effective for herpes zoster, which is a viral infection. Choice C is irrelevant to herpes zoster as it pertains to sharing personal items that may transmit head lice or certain skin infections. Choice D is also unrelated as it focuses on dry patches, not typical manifestations of herpes zoster which presents as a painful rash.

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: B

Rationale: The correct answer is B: High Fowler's position. High Fowler's position is the most appropriate for a client with chronic heart failure experiencing dyspnea and low oxygen saturation. This position helps improve lung expansion and oxygenation by maximizing chest expansion and allowing better ventilation. Choice A, supine with legs elevated, may worsen dyspnea by reducing lung expansion. Choice C, prone with pillows under the chest, is not suitable for a client experiencing dyspnea as it may further compromise breathing. Choice D, side-lying with head flat, does not facilitate optimal lung expansion and is not the best choice for improving oxygenation in this scenario.

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.
