The diabetic patient is put on an insulin drip to manage his blood glucose levels. He is currently receiving 6 units/hour. Pharmacy sends Humulin R 200 units in 500 ml Normal Saline. The infusion pump should be set at how many ml/hr

1 answer

To determine the rate at which the insulin drip should be infused, we can first calculate the number of units of insulin in each milliliter of the infusion solution.

Humulin R 200 units in 500 ml means there are 0.4 units of insulin in each milliliter of solution (200 units / 500 ml = 0.4 units/ml).

Since the patient is currently receiving 6 units/hour, we can calculate the rate of infusion by dividing the desired dosage by the concentration of insulin in the solution.

6 units/hour / 0.4 units/ml = 15 ml/hr

Therefore, the infusion pump should be set at 15 ml/hr to deliver 6 units/hour of Humulin R to the patient.
