A nurse is reinforcing teaching with a client about dietary intake to promote wound healing.
Which of the following vitamins should the nurse recommend?
Vitamin C.
Thiamine.
Niacin.
Vitamin D.
The Correct Answer is A
Choice A rationale
Vitamin C is crucial for collagen synthesis, which is necessary for tissue repair and wound healing. It also enhances the immune response and promotes iron absorption, supporting the overall healing process.
Choice B rationale
Thiamine, a B-vitamin, facilitates carbohydrate metabolism and neural function. While essential, it does not have a direct role in wound healing or tissue regeneration.
Choice C rationale
Niacin supports energy production and DNA repair but lacks a specific role in promoting collagen synthesis or wound healing, making it less critical for this purpose.
Choice D rationale
Vitamin D maintains calcium-phosphorus homeostasis and bone health. While important for skeletal support, it does not directly enhance wound healing mechanisms.

Correct Answer is D
Explanation
Choice A rationale
Removing personal protective equipment outside the client’s room increases the risk of environmental contamination with pathogens. Contact precautions require careful containment of contaminants within the room to prevent the spread of infectious agents to other areas of the healthcare facility, thus making this action inappropriate.
Choice B rationale
An N95 mask is not required for contact precautions but is designated for airborne precautions, such as for tuberculosis or measles. Contact precautions focus on minimizing the spread of infections via touch or contact with bodily fluids, requiring gowns and gloves rather than high-filtration masks.
Choice C rationale
Using an alcohol swab to clean the temperature probe before removing it from the room may not eliminate all pathogens. Probes that contact mucous membranes or bodily fluids should undergo high-level disinfection or sterilization. Ensuring single-patient use of equipment is more effective in preventing cross-contamination in this context.
Choice D rationale
Assigning a dedicated stethoscope for the client during their hospital stay minimizes the risk of transmitting pathogens to other clients. Equipment designated for single-client use remains in the client’s room, reducing the chance of contamination and maintaining infection control measures effectively, aligning with best practices for contact precautions.
Correct Answer is ["119"]
Explanation
Step 1 is to convert the client's weight from pounds to kilograms: 175 lb ÷ 2.2 = 79.545 kg.
Step 2 is to calculate the dose: 1.5 mg × 79.545 kg = 119.3175 mg.
Step 3 is to round the answer to the nearest whole number: 119 mg. Final answer: 119 mg.
