2 If a nursing assistant is not sure what information to share at the care conference, she should

Correct Answer: A

Rationale: The correct answer is A because talking to the nurse before the meeting allows the nursing assistant to clarify what information is relevant to share during the care conference. This step ensures that the assistant is well-prepared and can contribute valuable insights during the meeting. Option B is incorrect as avoiding the meeting does not address the issue of uncertainty and misses the opportunity to seek clarification. Option C is also incorrect as attending the meeting without sharing any information defeats the purpose of active participation. Option D is incorrect because relying on other team members to determine what information to share may not align with the assistant's responsibilities and expertise.

Correct Answer: A

Rationale: Rationale for correct answer (A): Covering the mouth when sneezing helps prevent the spread of infectious respiratory droplets, reducing the risk of transmission. This action directly addresses the portal of exit in the chain of infection by containing potential pathogens. Summary: B (Keeping surfaces clean and dry) does not specifically target the portal of exit, focusing more on the mode of transmission. C (Getting a vaccine for a particular disease) is related to prevention but does not directly address the portal of exit. D (Handwashing) is crucial for infection prevention but is more aligned with breaking the chain of transmission rather than specifically targeting the portal of exit.

Correct Answer: D

Rationale: Step 1: Checking water temperature before giving a bath or shower ensures it is not too hot, preventing burns. Step 2: This practice aligns with safety guidelines to prevent scalds and burns. Step 3: It demonstrates a proactive approach to protecting individuals from harm. Step 4: Other choices are incorrect as they involve risky behaviors that can lead to burns or scalds. Summary: Choice D is correct as it promotes safety by preventing burns through proactive measures. Choices A, B, and C are incorrect as they encourage unsafe practices that can increase the risk of burns and scalds.

Correct Answer: D

Rationale: The correct answer is D. When poisoning is suspected, a nursing assistant should look for a container to find out what the resident ingested. This step is crucial in determining the specific poison and assisting medical professionals in providing appropriate treatment. Choice A is incorrect because inducing vomiting can worsen the situation. Choice B is incorrect as feeding crackers or bread may not address the poisoning. Choice C is incorrect because giving medication without knowing the poison can be harmful. Overall, choice D is the best course of action as it helps identify the poison and guides proper medical intervention.

Correct Answer: C

Rationale: The circadian rhythm is the 24-hour cycle that regulates our sleep-wake pattern, hormone release, body temperature, and other physiological processes. It is governed by the body's internal clock. Choice A is incorrect as it oversimplifies the circadian rhythm. Choice B is incorrect as deep sleep is just one part of the sleep cycle, not the circadian rhythm itself. Choice D is incorrect as the circadian rhythm goes beyond just the day-night cycle, encompassing all bodily functions over a 24-hour period. Therefore, the correct answer is C, the 24-hour cycle that influences various biological processes.
