Calculation
The nurse is preparing a heparin drip for a client who weighs 242 lb. The available heparin is infusion 25,000 units in 500 ml 0.9% sodium chloride. The order is to deliver a bolus then initiate a drip at 14 units/kg/hr. What will the nurse program the infusion pump to deliver? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL/hr
Explanation & Rationale
Rationale: Step 1: Convert weight from pounds to kilograms: 242 lb ÷ 2.2 = 110 kg Step 2: Calculate the dose in units/hr: 14 units/kg/hr × 110 kg = 1540 units/hr Step 3: Determine the concentration of heparin: 25,000 units ÷ 500 mL = 50 units/mL Step 4: Calculate mL/hr to deliver the ordered units: 1540 units/hr ÷ 50 units/mL = 30.8 mL/hr Final Answer: 30.8 mL/hr
