How does sarcopenia impact functional independence in older adults?

Correct Answer: D

Rationale: The correct answer is D because sarcopenia, which is the age-related loss of muscle mass and strength, directly impacts balance and mobility in older adults. Muscle weakness from sarcopenia reduces stability and coordination, increasing the risk of falls. This affects functional independence as it limits the ability to perform daily activities safely. Choices A, B, and C are incorrect as sarcopenia primarily affects muscle mass and strength, not body fat, lung capacity, or joint stiffness.

Correct Answer: B

Rationale: The correct answer is B: Thyroid gland. The thyroid gland produces hormones that regulate metabolism. In older adults, decreased thyroid function, known as hypothyroidism, can lead to a decrease in metabolism. This can result in symptoms such as fatigue, weight gain, and slowed heart rate. A: Kidney - While the kidneys play a role in filtering waste and maintaining fluid balance, decreased kidney function typically does not directly impact metabolism. C: Brain - The brain plays a crucial role in regulating various bodily functions, but it does not directly control metabolism. D: Skeleton - The skeleton provides structural support and protects organs but does not directly influence metabolism.

Correct Answer: C

Rationale: The correct answer is C because assigning female nurses to older women who are Islamic respects their cultural and religious beliefs, promoting holistic care. This approach considers the older adult's physical, emotional, social, and spiritual needs, aligning with the principles of holistic nursing care. Choice A is incorrect because performing glucose testing during a weekly worship service does not necessarily address the older adult's holistic needs. Choice B is incorrect as simply wheeling ambulatory adults to exercise when running late does not encompass a holistic approach. Choice D is incorrect as allowing older adults in a nursing home to eat meals alone may neglect their social and emotional well-being.

Correct Answer: A

Rationale: The correct answer is A: Genetic research. Telomere shortening is primarily based on the theory of cellular senescence, which is related to genetic research. Telomeres are protective caps at the end of chromosomes that shorten with each cell division. Genetic research has shown that telomere shortening is associated with aging and age-related diseases. Caloric restriction, oxidative stress, and cross-link theories of aging are not directly linked to telomere shortening. Caloric restriction focuses on extending lifespan by reducing calorie intake, oxidative stress theory suggests that aging is caused by cumulative damage from reactive oxygen species, and cross-link theory emphasizes the accumulation of non-reversible bonds between molecules as a cause of aging.

Correct Answer: B, E, F

Rationale: The correct answers are B, E, and F. B is correct because understanding what treatment can improve the condition is essential for culturally sensitive care. E is correct as it helps understand the patient's beliefs about the cause of the illness. F is correct to assess the impact of the illness on the patient's life. A is incorrect as it focuses more on negotiation rather than understanding the patient's perspective. C is incorrect as it assumes the nurse's plan is superior without considering the patient's beliefs. D is incorrect as it only focuses on the duration of the problem rather than the patient's explanatory model.
