What medication and dose should be used for mild/moderate pain in a pediatric patient?

• A. Acetaminophen 15 mg/kg IV/IO; maximum single dose 1 g slow IVP over 2 mins
• B. Fentanyl 1 mcg/kg IN/IM/IV/IO; max 100 mcg
• C. Morphine 0.1 mg/kg IM/IV/IO; max 10 mg
• D. Ketamine 1 mg/kg IV/IO

Answer: (A)

For mild to moderate pain in a pediatric patient, non-opioid analgesia is preferred first because it provides effective relief with a lower risk of serious side effects. Acetaminophen at 15 mg/kg per dose is the standard weight-based amount, with a maximum single dose of 1 gram. Giving it via IV or IO when access is already in place allows rapid onset, and delivering it slowly over about 2 minutes helps keep the infusion gentle and well tolerated. This approach minimizes the need for opioids, which carry greater risks of respiratory depression and oversedation in children. If pain remains uncontrolled after acetaminophen, clinicians would consider other options with careful monitoring, but for mild to moderate pain, acetaminophen is the best initial choice. Ketamine, while useful in certain situations, is not the first-line option for mild/moderate pain due to its potential side effects and the need for specific indications; opioids like fentanyl or morphine are more appropriate when pain is moderate to severe or when non-opioid analgesia is insufficient.
