Before a patient is to receive intrathecal chemotherapy, which precaution is essential?

• A. Ensure developmentally appropriate patient teaching is completed
• B. Verify the patient's white blood cell count
• C. Ensure other chemo agents are available to administer
• D. Apply LMX cream between L5-L7

Answer: (A)

Before intrathecal chemotherapy, making sure the patient and family receive developmentally appropriate teaching is essential. This procedure carries specific risks and requires informed consent, so explaining what will happen, why it’s done, potential side effects, and what to monitor afterward helps the patient and guardians understand and participate in safety decisions. Tailoring the information to the child’s or caregiver’s developmental level reduces fear, improves cooperation during the procedure, and supports proper post-procedure care.

While laboratory checks like a white blood cell count are important for overall chemotherapy safety, and other administrative steps or topical anesthetics may be considered in some contexts, the fundamental precaution tied to this moment is ensuring clear, age-appropriate education and consent.
