A child who weighs 30 kg is experiencing a grand mal seizure. The healthcare provider prescribes diazepam 0.3 mg/kg/dose intravenous (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).

Step 1: Calculate the total dose of diazepam for this child by multiplying the child’s weight (30 kg) by the prescribed dose (0.3 mg/kg). This calculation gives a total dose of 9 mg (30 kg × 0.3 mg/kg = 9 mg). Step 2: Divide the total dose (9 mg) by the concentration of the medication (5 mg/mL) to determine the volume to be administered. This calculation gives a volume of 1.8 mL (9 mg ÷ 5 mg/mL = 1.8 mL).
