What is a critical step to prevent medication misadministration when preparing intrathecal chemotherapy?

• A. Use drugs clearly labeled for intrathecal use; prepare separately from IV meds; implement double-check of route, patient identity, and label.
• B. Rely on memory to confirm route.
• C. Mix intrathecal meds with IV meds.
• D. Use unlabeled vials.

Answer: (C)

A vital practice to prevent misadministration during intrathecal chemotherapy is to keep intrathecal drugs clearly separated from IV meds and to verify every step of the process. Drugs meant for intrathecal use must be specifically labeled for that route and prepared in a dedicated area, with a thorough double-check that confirms the route, the patient, and the label match before administration. This careful verification is essential because intrathecal administration delivers chemotherapy directly into the cerebrospinal fluid, and an error can cause immediate and severe harm. Mixing intrathecal meds with IV meds is dangerous and must be avoided, as it can lead to wrong-route administration, improper dosing, and dangerous interactions. Additional safeguards include independent checks by two licensed professionals, using dedicated, clearly labeled intrathecal syringes, and ensuring the label accompanies the drug from preparation through administration.
