Choice A rationale:

"I will keep my walker at the end of my bed." This statement indicates that the client understands the importance of having the walker within reach. Placing the walker at the end of the bed ensures that the client can use it immediately upon getting up, providing support and stability, thus reducing the risk of falls.

Choice B rationale:

"I will keep the fluorescent ceiling light on in my room at night." While having adequate lighting is important, using a fluorescent ceiling light throughout the night might disrupt the client's sleep. Additionally, a nightlight or a bedside lamp with a low-wattage bulb can provide sufficient illumination without disturbing sleep.

Choice C rationale:

"I will place an area rug at the entry of my bathroom." This statement indicates a lack of understanding. Area rugs can be tripping hazards, especially in areas prone to moisture like bathrooms. It is advisable to remove rugs and ensure non-slip flooring to prevent slips and falls.

Choice D rationale:

"I will place a bath seat in my shower to use when I bathe." While using a bath seat is a good safety measure, it does not address the client's risk of falling outside the shower area. Installing grab bars and non-slip mats in the bathroom, along with removing potential hazards, would be more comprehensive in ensuring the client's safety. .

Tuberculosis (TB) is an airborne disease, and healthcare workers need to wear an N95 respirator to protect themselves from inhaling the bacteria.

Choice D rationale:

Scarlet fever is spread through respiratory droplets, but it does not require airborne precautions. Standard precautions are usually enough.
