Administer heparin 1000 units per hour IV. The pharmacy supplies the heparin infusion as 25.000 units in 500 mL DSW. What will the IV pump be set to? (Include unit of measure with answer).
The Correct Answer is ["20"]
Heparin infusion calculation:
- Heparin dose ordered: 1000 units per hour
- Heparin concentration: 25,000 units in 500 mL
- Conversion: 1 mL = 500 units
Calculations:
- Units per hour = 1000 units
- Units per mL = 25,000 units / 500 mL = 50 units/mL
- mL per hour = 1000 units / 50 units/mL = 20 mL/hr
Answer: The IV pump should be set to 20 mL/hr.
