A nurse is preparing to administer epinephrine 0.01 mg/kg subcutaneous to a school-age child who weighs 66 lb. Available is epinephrine injection 1 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the child's weight from pounds (lbs) to kilograms (kg): Formula: Weight in kg = Weight in lbs / 2.2 lbs/kg = 66 lbs / 2.2 lbs/kg = 30 kg Calculate the total dose of epinephrine needed in milligrams: Ordered dose: 0.01 mg/kg Child's weight in kg: 30 kg Formula: Total dose (mg) = Ordered dose (mg/kg) × Child's weight (kg) = 0.01 mg/kg × 30 kg = 0.3 mg Determine the concentration of the available epinephrine injection: Available concentration: 1 mg/mL Calculate the volume of epinephrine to administer: Formula: Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL) = 0.3 mg / 1 mg/mL = 0.3 mL
