Correct Answer: D

Rationale: The correct answer is D: Circulatory problems related to age and a chronic illness. Severe edema, hair loss on the legs, and foot ulcerations are indicative of poor circulation, often seen in conditions like peripheral artery disease. Age and chronic illnesses can contribute to circulatory issues. A diet low in protein (choice A) would not directly cause these symptoms. Exposure to cold (choice B) would not explain the specific symptoms mentioned. Frequent falls (choice C) do not align with the symptoms provided.

Correct Answer: B

Rationale: The correct answer is B: Malnutrition and dehydration. Malnutrition and dehydration are major risk factors for pressure ulcers in older adults because they can lead to poor skin integrity, reduced tissue resilience, and impaired wound healing. Lack of sleep (choice A) may contribute to overall health issues but is not a direct risk factor for pressure ulcers. Excessive physical activity (choice C) can increase the risk of injury but does not directly cause pressure ulcers. High blood pressure (choice D) is a risk factor for cardiovascular issues but is not specifically linked to the development of pressure ulcers.

Correct Answer: C

Rationale: The most appropriate interview question for assessing a client's respiratory function is C: "Have you ever worked in a job where you were exposed to dust, fumes, smoke, or other pollutants?" This question directly relates to potential occupational exposures that could impact respiratory health. It helps gather specific information relevant to respiratory assessment. Choice A is unrelated to respiratory function assessment. Choice B focuses on familial history, which is important but not as direct as occupational exposure. Choice D is too general and does not specifically address respiratory issues. Therefore, C is the most appropriate choice for assessing respiratory function.

Correct Answer: A

Rationale: The correct answer is A: Free radical theory. Vitamin C is thought to prevent aging by combatting free radicals, which are highly reactive molecules that can damage cells and contribute to aging. Vitamin C acts as an antioxidant, neutralizing free radicals and protecting cells from oxidative damage. Immunological theory (B) focuses on the role of the immune system in aging. Oxidative stress theory (C) is related to free radical theory but does not specifically address the role of vitamin C. Telomere theory (D) pertains to the shortening of telomeres, which are protective structures at the end of chromosomes, but is not directly related to the role of vitamin C in preventing aging.

Correct Answer: A

Rationale: The correct answer is A: Promoting wellness. Providing information about diet and exercise for a healthy diabetic client falls under promoting wellness because it focuses on proactive measures to maintain health and prevent complications. It aims to empower the client to make healthy lifestyle choices. B: Preventing illness is not the best description as the client is already diabetic, so the focus is on managing the condition rather than solely preventing it. C: Treating disease is not accurate because the client is already diabetic and the goal is not to treat the disease, but rather manage it effectively. D: Restoring health is not applicable in this scenario as the client is not in a state of compromised health that needs to be restored.
