A nurse is preparing to administer 0/9% sodium chloride (0.9% NaCl) 20ml/kg IV tp infuse over 6 hr to a school-age child who weighs 55 lbs. The nurse should set the IV pump to deliver how many ml/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Ordered dose of 0.9% Sodium Chloride: 20 mL/kg Child's weight: 55 lbs Infusion time: 6 hours 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 volume of 0.9% Sodium Chloride: Total volume (mL) = Ordered dose (mL/kg) x Child's weight (kg) Total volume (mL) = 20 mL/kg x 24.94756 kg Total volume (mL) = 498.9512 mL Step 3: Calculate the infusion rate in mL/hr: Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr) Infusion rate (mL/hr) = 498.9512 mL / 6 hr Infusion rate (mL/hr) = 83.15853333 mL/hr Step 4: Round to the nearest whole number: Infusion rate (mL/hr) ≈ 83 mL/hr
