Question

1. Your client weighs 75 kg. Mix 250 units of Humulin regular insulin in 500 mL of 0.9% NS. 2) Begin continuous Humulin regular insulin infusion at 0.1 units/kg/hour IV. 3) Calculate _____units = _____mL/hr            

Answer 1

ANSWER.

* Order = 0.1 unit/kg/hour.

   Formula = Desired dose / Dose in hand * Quantity.

       Weight of the patient = 75 kg.

     So

       Desired dose(D) = 75 * 0.1

                             = 7.5 units.

       Dose in hand (H) = 250 unit.

            Quantity (Q) = 500 ml.

As per formula

        Amount (units) of insulin needed = D/H * Q

                                                             = 7.5/250 * 500

                                                             = 0.03 * 500

                                                             = 15 ml

      Amount required as ml/hr = 15 ml/hr.

      So

               * 7.5 units = 15 ml/hr.
