Which principle is most important for maintaining medical asepsis in a healthcare setting?

Correct Answer: D

Rationale: The correct answer is D: Clean hands thoroughly before and after patient contact. Hand hygiene is crucial for maintaining medical asepsis in a healthcare setting as it helps prevent the spread of infections between patients and healthcare workers. Choice A is incorrect because instruments should be sterilized regularly, not just when visibly contaminated. Choice B is incorrect as sterile gloves are not required for all patient interactions, only for specific procedures. Choice C is incorrect because patient areas should be disinfected regularly throughout the day, not just at the end of the day.

Correct Answer: B

Rationale: The most appropriate instruction to prevent falls at home is to remove loose rugs and install grab bars in high-risk areas like the bathroom. This helps eliminate tripping hazards and provides stability for the patient. Keeping the living space well-lit (Choice A) is important but may not directly address fall prevention. Using furniture for support (Choice C) can lead to accidents if the furniture is not stable. Wearing socks without shoes (Choice D) increases the risk of slipping rather than preventing falls.

Correct Answer: B

Rationale: The correct answer is B because ensuring two nurses double-check medications before administration is a crucial step in minimizing the risk of medication errors. This practice helps in verifying the accuracy of medication orders and reducing the chances of mistakes. Choice A may not necessarily prevent errors as preparing medications ahead of time does not guarantee accuracy. Choice C, administering medications at the same time each day, is important for consistency but does not directly address the risk of errors. Choice D, relying on memory, is highly discouraged as it increases the likelihood of errors due to human forgetfulness.

Correct Answer: A

Rationale: The correct answer is A because advancing the walker too far ahead increases the risk of falls, indicating a need for further teaching. Choice B is correct as using the walker to assist in standing is a proper use. Choice C is correct as maintaining balance while using the walker shows proper technique. Choice D is incorrect as walking with the back hunched over is a posture issue, not directly related to walker use.

Correct Answer: B

Rationale: Checking the placement of the NG tube before each feeding is crucial to ensure it is correctly positioned and safe to use. Option A is incorrect as routine suctioning can lead to complications and should only be done as needed. Option C is not necessary unless there are specific instructions for flushing. Option D is incorrect as the NG tube should only be removed by healthcare professionals based on medical criteria, not solely based on the patient's comfort.
