Which of the following statements is true of a living will?

Correct Answer: C

Rationale: Step 1: A living will is a legal document that outlines a person's preferences for medical treatment in case they are unable to communicate their wishes. Step 2: Choice C states that a living will states the medical care a resident wants or does not want if they become unable to make decisions, which aligns with the definition. Step 3: Choice A is incorrect because a living will does not pertain to the distribution of a large estate upon death. Step 4: Choice B is incorrect as a living will is not related to a resident's inheritance wishes but rather their medical care preferences. Step 5: Choice D is incorrect as a living will does not address financial affairs but focuses solely on medical treatment preferences. Summary: The correct answer, Choice C, accurately describes the purpose of a living will in outlining medical care preferences, making it distinct from the other choices that are unrelated to its intended use.

Correct Answer: A

Rationale: The correct answer is A: Social development. School-age children's development includes forming relationships, understanding social norms, and developing communication skills. This is crucial for their emotional well-being and success in school. Pregnancy (B) is not relevant to school-age children. Learning to walk correctly (C) is typically achieved during infancy. Controlling bowels and bladders (D) is part of early childhood development, not specific to school-age children. Thus, A is the correct answer.

Correct Answer: D

Rationale: The correct answer is D: Vaccine. A vaccine is specifically designed to produce immunity to a particular disease by stimulating the body's immune system to recognize and respond to the disease-causing agent. Vaccines contain weakened or inactivated forms of the pathogen, allowing the immune system to develop memory cells for future protection. Rationale: A: Vesicle is a small blister-like structure and is not used to produce immunity. B: Vector is an organism that transmits a pathogen but is not directly involved in producing immunity. C: Vacuum is a space entirely devoid of matter and is not related to immunity or disease prevention.

Correct Answer: B

Rationale: The correct answer is B: The NA should not measure blood pressure on an arm with an IV. This is because measuring blood pressure on an arm with an IV can disrupt the IV line, leading to potential complications such as infiltration or dislodgment. It is important to avoid applying pressure or constricting the area around the IV site to ensure proper flow of fluids and medication. Explanation of other choices: A: The NA should not disconnect the IV line when the bag is empty as this can lead to air entering the line, causing air embolism. C: The NA should avoid getting the IV site wet during the resident's bath to prevent infection or dislodgment of the IV catheter. D: Lowering the IV bag below the site for short intervals is not recommended as it can cause an uneven flow rate and compromise the effectiveness of IV therapy.

Correct Answer: B

Rationale: The correct answer is B: The side rail should be raised on the far side of the bed (side farther away from the NA). This is because it ensures the resident's safety and prevents falls while allowing the nursing assistant easy access to make the bed without obstructing the resident. Raising both side rails (choice A) unnecessarily restricts the resident's movement. Raising the near side rail (choice C) may hinder the nursing assistant's ability to efficiently make the bed. Lowering both side rails (choice D) compromises the resident's safety.
