A nurse is preparing to administer diazepam 0.3 mg/kg IV bolus to a toddler who weighs 24 lb. Available is diazepam injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the toddler's weight from pounds (lb) to kilograms (kg) using the conversion factor of 2.2 lb/kg. Patient's weight in kg = 24 lb / 2.2 lb/kg = 10.9090 kg. Calculate the dose in milligrams (mg) for the child. Dose (mg) = Ordered dose (mg/kg) × Patient's weight (kg) = 0.3 mg/kg × 10.9090 kg = 3.2727 mg. Available concentration = 5 mg/mL. Calculate the volume in milliliters (mL) to administer per dose. Volume (mL) = Dose (mg) / Available concentration (mg/mL) = 3.2727 mg / 5 mg/mL = 0.6545 mL. Round the answer to the nearest hundredth. = 0.65 mL.
