Fentanyl - Pediatric (ALS): If a 10 kg child is given 0.5 mcg/kg IV fentanyl, how many micrograms is that dose?

• A. 5 mcg
• B. 10 mcg
• C. 2 mcg
• D. 1 mcg

Answer: (A)

Weight-based dosing is how pediatric fentanyl doses are calculated. To find the total dose, multiply the dose per kilogram by the child’s weight in kilograms. Here, 0.5 mcg/kg × 10 kg = 5 mcg, so the total dose is 5 micrograms. This illustrates the straightforward rule: dose (mcg) = dose per kg (mcg/kg) × weight (kg).
