A nurse is preparing to administer a continuous heparin infusion at 1600 units/hr. Available is heparin 25.000 units in dextrose 5% in water (DSW) 500 mL The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["32"]
1. Determine the concentration of heparin in the solution:
- There are 25,000 units of heparin in 500 mL of D5W.
- Concentration = 25,000 units / 500 mL = 50 units/mL.
2. Calculate the required mL/hr for the desired infusion rate:
- The order is for 1600 units/hr.
- To find the mL/hr:
ML/HR=desired units/hr divided by unts/ml
=1600/50
=32ml/hr
