A nurse is providing care for a patient who has deep vein thrombosis.
The patient is prescribed heparin, which is to be administered via continuous IV infusion at a rate of 1,200 units/hr. If the available heparin is 25,000 units in 500 mL DSW, how many mL/hr should the IV pump be set to deliver?
(Round your answer to the nearest tenth or whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["24"]
Step 1 is: To find out how many mL/hr the IV pump should be set to deliver, we need to set up a proportion with the prescribed units of heparin on one side and the available units of heparin on the other side. So, the calculation is: (1,200 units/hr ÷ 25,000 units) × 500 mL = 24 mL/hr.
Therefore, the IV pump should be set to deliver 24 mL/hr.
