17. Order: Humulin R 100 units IVPB in 500 mL NS infuse at 0.1 unit/kg/h stat. The patient weighs 46 kg. How long will it take for the infusion of
this U-100 insulin to complete?

17) Calculation of time required for the infusion to complete.

            Rate(ml/hr) = Total volume(ml) / Time(hr).

               Time(hr) = Total volume(ml) / Rate(ml/hr).

        Calculation of volume(ml).

                 Formula = Desired dose/Dose in hand *Quantity.

       Ordered dose = 0.1 unit/kg/hr.

        Weight of the patient = 46 kg.

      Desired dose(D) for this patient = 0.1 * 46

                                                                      = 4.6 unit / hr.

                   Dose in hand(H) = 100 unit

                          Quantity(Q) = 500 ml.

    As per above formula

              Volume required = 4.6 / 100 * 500

                                          = 0.046 * 500

                                          = 23 ml.

            Rate = 23 ml /hr.

            Time(hr) = Total volume(ml) / Rate(ml/hr)

                           = 500/ 23

                           = 21.7

                           = 22 hr (Time required to complete the infusion).

Hope this helps... . *brainliest please?*
