Final answer:
To administer heparin at a rate of 1,300 units per hour, the IV pump should be programmed to deliver 13 mL of heparin per hour.
Step-by-step explanation:
The IV pump would need to be programmed to deliver a certain amount of milliliters per hour in order to administer the heparin at a rate of 1,300 units per hour. To calculate the mL per hour, you can use the volume ratio formula:
Volume Ratio = (Ordered Units / Available Units) x Available Volume
Substituting the given values, the calculation would be:
(1,300 units / 25,000 units) x 250 mL = 13 mL
Therefore, the IV pump should be programmed to deliver 13 mL of heparin per hour.
