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: 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: C

Rationale: In a patient with multiple rib fractures, severe pulmonary contusions, and possible acute Respiratory Distress Syndrome (ARDS), tachypnea (rapid breathing) with dyspnea (shortness of breath) is a critical sign of respiratory distress that warrants immediate intervention by the nurse. Tachypnea and dyspnea indicate inadequate oxygenation and ventilation, which can lead to respiratory failure if not addressed promptly. The other options, such as apical pulse rate, core body temperature, and bruises over the chest area, are important assessments but do not directly indicate the immediate need for intervention in a patient with respiratory distress.

Correct Answer: B

Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.

Correct Answer: C

Rationale: The correct answer is C. Decreasing the number of cigarettes smoked per day is not sufficient for CAD prevention. Smoking cessation is crucial in reducing the risk of CAD. While increasing physical activity, eating a low-fat diet, and monitoring blood pressure regularly are all positive behaviors for CAD prevention, quitting smoking should be emphasized due to its significant impact on cardiovascular health.
