A nurse is preparing to administer furosemide 1 mg/kg IV bolus to a preschooler who weighs 36 lb. Available is furosemide injection 10 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the preschooler's weight from pounds (lb) to kilograms (kg) using the conversion factor of 2.2 lb/kg. Patient's weight in kg = 36 lb / 2.2 lb/kg = 16.3636 kg. Calculate the dose in milligrams (mg) for the child. Dose (mg) = Ordered dose (mg/kg) × Patient's weight (kg) = 1 mg/kg × 16.3636 kg = 16.3636 mg. Available concentration = 10 mg/mL. Calculate the volume in milliliters (mL) to administer per dose. Volume (mL) = Dose (mg) / Available concentration (mg/mL) = 16.3636 mg / 10 mg/mL = 1.63636 mL. Round the answer to the nearest tenth. = 1.6 mL.
