A nurse is planning care for a child who has neutropenia due to leukemia. Which of the following interventions should the nurse include in the plan of care?

Neutropenia significantly increases the risk of infection; screening visitors for active infections is critical to protect the immunocompromised child. Platelet transfusion is indicated for thrombocytopenia (low platelets), not neutropenia. A high-protein diet (not low) supports immune function and tissue repair. Monitoring for bleeding is associated with thrombocytopenia, not neutropenia.
