A nurse is assisting in the care of a client who has cancer and has a white blood cell count of 4,000/mm. Which of the following actions should the nurse take?

This scenario involves a cancer client with mild leukopenia, as the white blood cell count is 4000/mm, which is at the lower limit of the normal range of 5000 to 10000/mm. Knowledge of infection prevention and neutropenic precautions must be applied to minimize pathogen exposure. Choice A rationale Unpasteurized dairy products contain live bacteria, such as Listeria monocytogenes, which pose an infection risk. Immunocompromised clients must consume only pasteurized foods to avoid foodborne illness from opportunistic pathogens. Choice B rationale Decreasing protein intake hinders tissue healing, cellular repair, and the synthesis of immunoglobulins. Cancer clients require adequate or increased protein intake to support immune function and maintain lean muscle mass during therapy. Choice C rationale Cleansing the toothbrush with hydrogen peroxide kills resident bacteria and prevents microbial proliferation on the bristles. This reduces the risk of introducing opportunistic oral pathogens into the oral cavity during daily hygiene. Choice D rationale Disposable razors pose a high risk of skin nicks and microabrasions, creating a portal of entry for pathogens. Clients with low blood counts should use an electric shaver to minimize skin trauma.
