What is the IV dose for morphine sulfate?

• A. 0.05 mg/kg IV
• B. 0.1 mg/kg IV
• C. 0.2 mg/kg IV
• D. 0.4 mg/kg IV

Answer: (B)

Weight-based dosing is used for IV morphine to achieve analgesia while minimizing respiratory risk. The standard starting IV dose is 0.1 mg per kilogram, given as a bolus and then titrated to effect with careful monitoring. Doses as small as 0.05 mg/kg may be used in some situations, but 0.1 mg/kg is the most common starting point in many pediatric/ED protocols. Higher doses like 0.2 mg/kg or 0.4 mg/kg greatly increase the risk of oversedation and respiratory depression. Always monitor respirations and oxygenation after administration and be prepared to intervene if needed.
