A 7-year-old child is newly diagnosed with acute lymphoblastic leukemia (ALL). The nurse is preparing the family for the treatment plan. Which of the following nursing interventions is most important for the nurse to include in the plan of care for this child during the induction phase of chemotherapy?

A. Administering pain medications to relieve headache and muscle aches is important for comfort, but it is not the highest priority during the induction phase. B. Monitoring for signs of infection due to neutropenia is correct because induction chemotherapy causes profound bone marrow suppression, leading to neutropenia. Neutropenia significantly increases the risk of infection, which can become life-threatening. Early detection of fever, chills, or other infection signs is critical for timely intervention, making infection prevention and monitoring the top priority during this phase. C. Recommending home-schooling to minimize exposure to other children is supportive and helpful for infection prevention but is secondary to direct monitoring and management of neutropenia. D. Encouraging a high-protein diet to promote growth is beneficial for overall health and recovery but is not the primary concern during the induction phase, when preventing infection is life-saving.
