Which of the following is a function of the bones?

Correct Answer: B

Rationale: The correct answer is B: Lending support to body structures. Bones provide structural support for the body, protect vital organs, and allow for movement. They also serve as storage for minerals and production of blood cells. Protecting the body from disease (A) is mainly the function of the immune system. Sending messages throughout the human body (C) is the role of the nervous system. Pumping blood throughout the body (D) is the function of the heart and circulatory system.

Correct Answer: A

Rationale: The correct answer is A because normal age-related changes in the endocrine system often involve a decrease in hormone levels, such as estrogen signaling menopause in women. This is a typical physiological process in aging females. Testosterone levels do not typically increase in males with age, making choice B incorrect. Insulin production may decrease or remain stable with age, but it does not typically increase, so choice C is incorrect. Lastly, the body's ability to handle stress usually decreases with age due to changes in hormone levels and other factors, making choice D incorrect.

Correct Answer: D

Rationale: The correct answer is D: 4. A quad cane has 4 feet for stability and support. Each foot touches the ground independently, providing balance and preventing falls. Choice A (1) is incorrect as a single foot would not provide adequate stability. Choice B (2) is incorrect as that would be a regular cane. Choice C (3) is incorrect as it would be a tri cane, not a quad cane.

Correct Answer: C

Rationale: The correct answer is C because listening to family and friends when they want to talk about their feelings is an essential aspect of providing emotional support during the grieving process. By actively listening, nursing assistants can offer empathy and comfort. Choice A is incorrect because calming upset family members does not address their emotional needs. Choice B is incorrect as asking them not to cry dismisses their emotions. Choice D is incorrect because showing empathy and support are crucial in helping family and friends cope with the resident's death.

Correct Answer: A

Rationale: The correct answer is A: Liability. Liability refers to legal responsibility for causing harm to someone else. In legal terms, it means being accountable for damages or injuries. The other choices are incorrect because: B: Lability is a misspelling and not a valid term in this context. C: Litigious means inclined to engage in lawsuits, not specifically about being responsible for harm. D: Misdemeanor is a criminal offense, not directly related to legal responsibility for harm.
