A client recovering from a total hip replacement has developed a deep vein thrombosis. The health-care provider has ordered a continuous infusion of heparin, an anticoagulant, to infuse at 1,200 units per hour. The bag comes with 20,000 units of heparin in 500 mL of 0.9% normal saline. At what rate should the nurse set the pump?
Correct answer
30
Rationale
Concentration: 20,000 units ├À 500 mL = 40 units/mL. Rate: 1200 units/hr ├À 40 units/mL = 30 mL/hr.
