Question 2 of 5
A client is prescribed heparin 2,000 units SC q8 hours. The pharmacy sends heparin 5,000 units/mL. How many mL should the nurse administer every 24 hours?

Correct Answer: 10.7 mL/hr.
Rationale: Concentration: 20,000 units/250 mL = 80 units/mL. Rate: 854 units/hr ÷ 80 units/mL = 10.675 mL/hr, rounded to 10.7 mL/hr.
