Infection prevention for the portal of exit link in the chain of infection could include

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: 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.

Correct Answer: D

Rationale: The correct answer is D because positioning the resident's hips at the very back of the chair helps distribute their weight evenly, preventing the wheelchair from tipping forward. This ensures stability and reduces the risk of falls or accidents. Choice A is incorrect because going down a ramp forward could lead to loss of control. Choice B is wrong as leaving the wheels unlocked is unsafe and may cause the wheelchair to move unexpectedly. Choice C is irrelevant to the guideline for wheelchair safety.

Correct Answer: A

Rationale: The correct answer is A because dressing the weak side first allows for better support and easier movement during the dressing process. By putting clothing on the weak side first, the resident can use the stronger side to assist in dressing the weaker side, promoting independence and safety. This approach also minimizes strain on the weak side and reduces the risk of injury. Choices B, C, and D are incorrect because putting clothing on the strong side first may cause imbalance, referring to the weak side as the bad side is disrespectful and stigmatizing, and stating that it does not matter which side clothing is put on first neglects the importance of considering the resident's needs and safety.
