Which routes are listed for Ondansetron use in pediatric nausea/vomiting?

• A. ODT/IM/IV/IO
• B. PO only
• C. IV only
• D. IM only

Answer: (A)

Ondansetron in pediatric nausea and vomiting is designed to be flexible across different patient situations, so multiple administration routes are listed. The dissolving oral tablet (ODT) lets a child receive the medicine quickly without needing water or a swallow, which is helpful when vomiting is present or swallowing is difficult. If rapid effect is needed or the child cannot take anything by mouth, intramuscular injection offers a viable alternative. When rapid onset is essential and IV access is available, the intravenous route delivers the medicine fastest. In urgent cases where IV access is challenging or not yet obtained, intraosseous delivery provides another quick option. Because the protocol supports all these routes, the answer that includes ODT, IM, IV, and IO is the best fit. Options that restrict administration to a single route don’t reflect the practical flexibility used in pediatric care.
