Calculation
A nurse is preparing to administer atropine 0.02 mg/kg via IV bolus to a school-age child who weighs 30 kg. Available is 0.4 mg/mL. How many mL should the nurse administer? (Round your answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero).
mL
Explanation & Rationale
Calculation: Calculate the total dose in milligrams (mg). Ordered dose: 0.02 mg/kg Patient weight: 30 kg Total dose (mg) = 0.02 mg/kg x 30 kg = 0.6 mg. Calculate the volume to administer in milliliters (mL). Total dose: 0.6 mg Available concentration: 0.4 mg/mL Volume (mL) = Total Dose (mg) / Available Concentration (mg/mL) = 0.6 mg / 0.4 mg/mL = 1.5 mL.
