A nurse is preparing to administer a continuous heparin infusion at 1600 units/hr. Available is heparin 25,000 units in dextrose 5% in water (DSW) 500 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
32 mL/hr
Rationale
Calculating (1600 units/hr × 500 mL) / 25,000 units yields 32 mL/hr for effective anticoagulation.
