A nurse is planning teaching for a client who has multiple sclerosis. Which of the following instructions should the nurse plan to include?

- Rationale for Choice A: Pulmonary hygiene is important for preventing pneumonia, especially in bedridden clients. However, it is not specific to the care of a client with leukemia unless they have a respiratory complication which necessitates such an intervention.
- Rationale for Choice B: Airborne precautions are typically used for clients who have infections that can be transmitted through the air, such as tuberculosis. Leukemia does not require airborne precautions unless the client has a coexisting airborne infection.
- Rationale for Choice C: Regular turning of the client can help prevent pressure ulcers and is a good practice for any bedridden patient. However, the use of powder is controversial as it can cake and lead to skin breakdown, and is not specifically indicated for leukemia care.
- Rationale for Choice D: Assessing the client's urine for odor and cloudiness is an important part of care for clients with leukemia. They are at increased risk for urinary tract infections due to immunosuppression, and changes in urine can indicate an infection that needs prompt treatment.

Choice A rationale:

A balanced diet that includes fruits and vegetables is important for overall health, but it is not specifically related to the timing of sexual intercourse for conception.

Choice B rationale:

Using a lubricant during sexual intercourse can sometimes interfere with sperm motility and decrease the chances of conception.

Choice C rationale:

Having sexual intercourse 2 days following ovulation can increase the chances of fertilization since sperm can survive in the female reproductive tract for several days, and the egg is viable for a shorter period.

Choice D rationale:

While the type of underwear worn by the partner can influence testicular temperature, there is limited evidence to support the claim that tight-fitting underwear significantly affects fertility.
