Question

The provider orders a Heparin infusion of 900 units/hr. Your IV medication on hand has 25,000 units of Heparin in 500 mL of D5W. How many mL/hr will you infuse?

Answer 1

To administer a Heparin infusion of 900 units/hr using the medication on hand (25,000 units in 500 mL), the infusion rate should be set to 18 mL/hr.

Step-by-step explanation:

To determine the mL/hr infusion rate, we need to calculate how many mL of Heparin is in 900 units. The question involves calculating the infusion rate in mL/hr for a Heparin IV. The provider has ordered a Heparin infusion at a dosage of 900 units/hr, and the medication on hand is 25,000 units of Heparin in 500 mL of D5W. The formula to calculate the IV flow rate is:

Infusion rate (mL/hr) = (Ordered amount (units/hr) × Volume of IV fluid (mL)) / Total amount of medication (units)

Using this formula, the calculation will be:

Infusion rate (mL/hr) = (900 units/hr × 500 mL) / 25,000 units = 18 mL/hr

Therefore, you will set the IV pump to infuse at 18 mL/hr to administer the ordered dosage of Heparin.
