A child who weighs 30 kg is experiencing a grand mal seizure. The healthcare provider prescribes diazepam 0.3 mg/kg/dose IV STAT. The medication is available in 5 mg/mL. vials. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth).

Calculation: Identify the desired dose based on the patient's weight. Desired dose (mg) = Patient weight (kg) x Ordered dose (mg/kg/dose) = 30 kg x 0.3 mg/kg = 9 mg. Available concentration = 5 mg/mL. Calculate the volume to administer in milliliters (mL). Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 9 mg / 5 mg/mL = 1.8 mL.
