Rationale: The correct answer is C, nail polish remover, because it contains volatile solvents like acetone, making it highly flammable. Water (A) is not flammable.

Correct Answer: A

Rationale: The correct answer is A. By putting oneself in the resident's shoes, the nursing assistant can empathize with their feelings and provide personalized support. This approach shows understanding and compassion, fostering trust and comfort. B: This choice is incorrect because it may create anxiety or guilt in the resident, leading to a negative adjustment experience. C: Covering up mistakes can erode trust and credibility, causing the resident to feel insecure and uneasy about the care provided. D: Forcing the resident to participate in activities goes against their autonomy and may result in resistance or resentment, hindering the adjustment process.

Correct Answer: A

Rationale: The correct answer is A: An alternating pressure mattress. This type of mattress helps reduce pressure on specific areas of the body by alternating pressure points, which can prevent pressure injuries. The other choices, B: A bariatric bed, C: An electric bed, and D: A closed bed, do not directly address the prevention of pressure injuries. Bariatric beds are designed for heavier individuals, electric beds assist with adjusting positions, and closed beds do not offer the necessary pressure relief for someone at risk of pressure injuries. Therefore, A is the most appropriate choice for addressing the specific needs of a resident at risk for pressure injuries.

Correct Answer: B

Rationale: The correct answer is B: Wash from cleanest to dirtiest. This approach helps prevent spreading dirt and bacteria from dirty areas to cleaner ones, reducing the risk of infections. It also maintains hygiene standards and promotes overall cleanliness. Choice A is incorrect as it can lead to cross-contamination. Choice C is not ideal as it may not prioritize effective cleaning. Choice D is incorrect as it disregards the resident's preferences and can be unhygienic.
