Question

A child is prescribed morphine sulfate at 45.0 mcg/kg/dose. The child weighs 99 lb and the solution is available as an 1.0-

mg/mL vial. How many milliliters should be injected?
Express your answer in milliliters to two significant figures.

Answer 1

2 ml

Step-by-step explanation:

First convert 99 pounds to 45 kg

45 kg * 45 mcg/kg/dose = 2025 mcg/dose = 2.025 mg/dose

2.025 (i'll round to 2 mg)

2 mg / dose / 1.0 mg/ml = 2 ml per dose
