A nurse is preparing to administer acetaminophen 10/mg/kg PO to a preschool child for fever. The child weighs 22 lb . Available is acetaminophen liquid 160mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Given: Ordered dose of acetaminophen: 10 mg/kg Child's weight: 22 lb Concentration of acetaminophen liquid: 160 mg/5 mL Step 1: Convert child's weight from pounds to kilograms: 1 pound (lb) = 0.453592 kilograms (kg) Child's weight in kg = 22 lbs x 0.453592 kg/lb = 9.976824 kg Step 2: Calculate the total dose of acetaminophen: Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg) Total dose (mg) = 10 mg/kg x 9.976824 kg Total dose (mg) = 99.76824 mg Step 3: Calculate the volume to be administered: Volume (mL) = Total dose (mg) / Concentration (mg/mL) Volume (mL) = 99.76824 mg / 160 mg/5 mL Volume (mL) = 99.76824 mg x (5 mL / 160 mg) Volume (mL) = 3.1177575 mL Step 4: Round to the nearest tenth: Volume (mL) ≈ 3.1 mL
