Which education would the nurse provide to parents of a preschool-aged child with leukemia undergoing chemotherapy?

The education that would be most beneficial for parents of a preschool-aged child with leukemia undergoing chemotherapy includes the importance of maintaining proper hygiene in the perianal area, especially after each bowel movement. Chemotherapy can significantly weaken the immune system, making children more susceptible to infections. Ensuring that the perianal area is cleaned thoroughly after bowel movements helps prevent irritation and potential infections, which is crucial for a child undergoing such treatment.

In this context, encouraging proper hygiene practices contributes to the overall health and well-being of the child during a time when they are particularly vulnerable. This preventive measure reduces the risk of complications associated with skin breakdown or infections, which can be more severe in immunocompromised children.

Other options do not address the key concerns regarding infection prevention and skin care for a child undergoing chemotherapy. Therefore, emphasizing the cleaning of the perianal area after bowel movements is the most appropriate and health-promoting education for the parents.
