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

Correct Answer: A

Rationale: Rationale: A is correct because talking to the nurse before the meeting allows the nursing assistant to clarify what information is relevant and ensure alignment with the care plan. By communicating with the nurse beforehand, the nursing assistant can contribute effectively during the care conference. Summary of other choices: B: Not attending the meeting would result in missed opportunities to provide valuable input. C: Attending the meeting but not saying anything defeats the purpose of participation and collaboration. D: Asking other team members at the meeting what they need to know may lead to inconsistency and lack of clarity in the information shared.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. The portal of exit is where the infectious agent leaves the reservoir host. 2. Covering the mouth when sneezing helps prevent the spread of respiratory infections through droplets. 3. By covering the mouth, the risk of releasing infectious droplets into the environment decreases, thus reducing transmission. 4. This practice is a direct way to prevent the exit of infectious agents from the reservoir host. Summary of why other choices are incorrect: - B: Keeping surfaces clean and dry is related to the mode of transmission or reservoir, not specifically to the portal of exit. - C: Getting a vaccine for a particular disease is a preventive measure but not directly related to the portal of exit. - D: Handwashing is important for infection prevention but is more related to breaking the chain at the mode of transmission stage, not at the portal of exit.

Correct Answer: D

Rationale: The correct answer is D: Check water temperature before giving a bath or shower. This is important to prevent burns and scalds as water that is too hot can cause serious injuries. By checking the water temperature beforehand, you can ensure it is safe for the individual. Placing hot drinks on the edges of tables (A) can increase the risk of spills and burns. Serving drinks while standing (B) does not directly address the issue of water temperature. Leaving warm water applications on for 30 minutes (C) is not recommended as it can also lead to burns. It is crucial to always check water temperature to prevent burns and scalds.

Correct Answer: D

Rationale: The correct answer is D because looking for a container that will help identify what the resident took or ate can provide crucial information to healthcare providers. By identifying the source of poisoning, appropriate treatment can be administered promptly. Explanation: - A (inducing vomiting) can be dangerous as it may worsen the situation by causing further harm. - B (feeding crackers or bread) is not recommended as it may interfere with medical treatment and delay proper care. - C (giving medication without knowing the exact poison) can be harmful and may worsen the resident's condition. In summary, option D is the most appropriate as it focuses on gathering essential information to assist healthcare professionals in providing effective treatment.

Correct Answer: C

Rationale: The circadian rhythm is the 24-hour biological cycle that regulates various physiological processes such as sleep-wake cycles, hormone production, and body temperature. It is synchronized with the day-night cycle. Choice A and B are incorrect as they focus solely on rest and sleep, not the full range of biological processes regulated by the circadian rhythm. Choice D is incorrect as it specifically refers to the day-night cycle, which is just one aspect of the circadian rhythm. The correct answer, C, encompasses the comprehensive definition of the circadian rhythm as a 24-hour biological cycle.
