Answer 1

ANSWER.

24) Calculation of Volume(ml) of drug required per dose.

               Volume(ml) = Desired dose/Dose in hand * Quantity.

        Here

              Desired dose(D) = 20,000000 unit per day.

              Dose in hand(H) = 1000000 unit.

                  Quantity(Q) = 1ml.

     As per formula

         Volume(ml) of drug required = D/H * Q

                                                       = 20000000 / 1000000 * 1

                                                       = 20 ml per day (4 divided doses)

         So

             Volume(ml) of drug required per dose = 20/4

                                                                          = 5 ml per dose.

25) Calculation of flow rate (ml/hr).

            Formula

                  Flow rate = Total volume(ml) / Time(hr)

       Here

             Volume(ml) = 100 ml.

             Time(hr) = 0.5 hr (30 min)

      As per above formula

            Flow rate (ml/hr) = 100 / 0.5

                                       = 200 ml/hr.
