A nurse is contributing to the plan of care for an older adult client who has a WBC of 2000/mm3 after three rounds of chemotherapy. Which of the following interventions should the nurse include in the plan?

Rationale: A. A WBC of 2,000/mm³ indicates leukopenia, which increases the risk of infection. Serving cooked fruits instead of raw fruits reduces exposure to bacteria and pathogens, as cooking kills microorganisms. This is a key infection-prevention measure for immunocompromised clients. B. Negative-pressure rooms are used for clients with airborne infections (e.g., tuberculosis) to contain pathogens, not to protect an immunocompromised client. For a client with neutropenia, a protective isolation or positive-pressure environment is preferred to reduce exposure to pathogens. C. Using an incentive spirometer helps prevent atelectasis and pneumonia, which is generally beneficial, but it does not directly prevent infections caused by neutropenia. It is not the priority infection-control intervention for a client with a WBC of 2,000/mm³. D. Any elevated temperature in a neutropenic client is a medical emergency and should be reported immediately, even if lower than 39.5°C, because infection can progress rapidly. Waiting for 4 hours or for a very high fever could delay critical intervention.
