Question 1 of 5
A nurse is preparing to administer heparin at 1,000 units/hr via continuous IV infusion to a client who had a coronary artery bypass graft. Available is heparin 25,000 units in dextrose 5% in water in 250 mL. The nurse should set the IV pump to deliver how many mL/hr?
Correct Answer: 10
Rationale: The correct answer is 10 mL/hr.
To calculate this, first determine the total units in the bag (25,000 units).
Then, divide this by the desired dose rate (1,000 units/hr) to get 25 hours. Next, divide the total volume of the bag (250 mL) by the total time in hours to get 10 mL/hr. This ensures the client receives the correct dose of heparin over the specified time. Other choices are incorrect because they do not follow the correct calculation method or do not result in the precise dosage required for the client's condition.
