mg
Explanation & Rationale
Given: Ordered dose of Atropine Sulfate: 0.01 mg/kg Child's weight: 44 pounds Step 1: Convert child's weight from pounds to kilograms: 1 pound (lb) = 0.453592 kilograms (kg) Child's weight in kg = 44 lbs x 0.453592 kg/lb = 19.958 kg Step 2: Calculate the total dose of Atropine Sulfate: Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg) Total dose (mg) = 0.01 mg/kg x 19.958 kg Total dose (mg) = 0.19958 mg Step 3: Round to the nearest tenth: Total dose (mg) ≈ 0.2 mg
