    Calculation

    The healthcare provider prescribes epinephrine 0.01 mg/kg intramuscularly (IM) for a child with asthma who weighs 55 pounds. The available medication is labeled, "1 mg/mL." Based on the child's weight, how many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest hundredth.)

    mL

    Explanation & Rationale

    Given: Ordered dose of Epinephrine: 0.01 mg/kg Child's weight: 55 pounds Concentration of Epinephrine: 1 mg/mL Step 1: Convert child's weight from pounds to kilograms: 1 pound (lb) = 0.453592 kilograms (kg) Child's weight in kg = 55 lbs x 0.453592 kg/lb = 24.94756 kg Step 2: Calculate the total dose of Epinephrine: Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg) Total dose (mg) = 0.01 mg/kg x 24.94756 kg Total dose (mg) = 0.2494756 mg Step 3: Calculate the volume to be administered: Volume (mL) = Total dose (mg) / Concentration (mg/mL) Volume (mL) = 0.2494756 mg / 1 mg/mL Volume (mL) = 0.2494756 mL Step 4: Round to the nearest hundredth: Volume (mL) ≈ 0.25 mL
