Correct Answer: B

Rationale: The correct answer is B because a red, swollen 3-day-old wound in an older person indicates delayed wound healing, which is abnormal. The skin's ability to heal slows down with age due to decreased collagen production and compromised immune response. Thinner and more fragile skin (choice A) are typical changes in older individuals but not necessarily abnormal. Greater number of freckles (choice C) is a common age-related change due to accumulated sun exposure. Loss of hair on the extremities (choice D) can occur with aging but is not necessarily abnormal unless it is sudden and widespread.

Correct Answer: C

Rationale: The correct answer is C because a decrease in alveolar elasticity is not a physical change that directly leads to an increasing incidence of hypertension in the older adult. Arterial stiffening and loss of elasticity (choice A) can lead to increased blood pressure. Changes in renal regulation of sodium and water (choice B) can impact fluid balance and blood pressure. Increasing body weight (choice D) can contribute to hypertension through increased strain on the cardiovascular system. Therefore, a decrease in alveolar elasticity is not directly related to hypertension in the same way as the other choices.

Correct Answer: D

Rationale: The correct answer is D because assisting residents with ambulation to meals promotes physical activity, which is known to reduce the risk of Alzheimer's disease. Physical activity increases blood flow to the brain, reduces inflammation, and promotes the growth of new brain cells. Keeping curtains open (choice A) may offer natural light but does not directly reduce the risk of AD. Offering beads for stringing (choice B) and showing movies (choice C) may provide cognitive stimulation but do not address the physical activity needed to decrease the risk of AD.

Correct Answer: B

Rationale: The correct answer is B: administer the lowest dose of 2 mg. In older adults, especially the elderly, it is essential to start with the lowest effective dose of medication to minimize the risk of adverse effects. This approach follows the principle of "start low and go slow" when administering medications to older adults due to age-related changes in drug metabolism and increased sensitivity to medications. Administering the lowest effective dose helps to reduce the risk of potential complications such as respiratory depression, sedation, and falls. Choice A (administer the highest dose of 6 mg) is incorrect because starting with the highest dose can increase the risk of adverse effects in older adults. Choice C (avoid the narcotic because of the risk of addiction) is incorrect as it is important to manage pain effectively in post-operative patients, and opioids can be safely used under proper supervision. Choice D (administer the dose only when the client asks for the medication 2 times) is incorrect as pain management should be

Correct Answer: B

Rationale: The correct answer is B: Increasing protein intake. Protein is crucial for maintaining muscle mass and strength in older adults, aiding in the prevention and management of malnutrition. Protein also supports immune function and wound healing. Reducing calorie intake (A) can exacerbate malnutrition, as older adults need adequate nutrition. Avoiding all fats (C) is not recommended as healthy fats are essential for brain health and nutrient absorption. Limiting hydration (D) can lead to dehydration and worsen malnutrition. In summary, increasing protein intake is the most important factor in managing malnutrition in older adults due to its vital role in maintaining overall health and preventing muscle loss.
