Final answer:
To fulfill the medication order of 10 units of regular insulin per hour with a concentration of 100 units in 250 mL, the IV pump should be programmed to deliver 25 mL/hr.
Step-by-step explanation:
The subject of the student's question is related to calculating the rate at which an IV pump should be programmed to deliver a specific dosage of regular insulin. The specific scenario given is to program an IV pump to deliver 10 units of insulin per hour, with a concentration of 100 units of regular insulin in 250 mL of solution. To determine the rate at which the IV pump should be programmed, you would use the formula:
Required Insulin Dosage (units/hr) × Volume of Solution (mL) / Total Insulin Units in Solution = IV Pump Rate (mL/hr)
For this case:
10 units/hr × 250 mL / 100 units = 25 mL/hr
The IV pump should be programmed to administer 25 mL of the insulin solution per hour to deliver a medication order of 10 units of insulin per hour.
