Calculation
A nurse is preparing to administer heparin 1,000 units/hr via continuous IV infusion to a client. Available is heparin 25,000 units in 0.9% sodium chloride 250 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.)
mL/hr
Explanation & Rationale
mL/h r= Ordered dose/ Available concentration Given: Ordered Units/hr = 1,000 units/hr Concentration = 25,000 units / 250 mL = 100 units/mL mL/hr = (1,000 units/hr)/100 units/mL =10 mL/hr The IV pump should be set to deliver 10 mL/hr.
