Answer #1

ANSWER.

* Calculation of ml/hr.

            ml/hr = Volume(ml) / Time(hr).

    Calculation of volume(ml)

          Formula = Desired dose/Dose in hand * Quantity.

   Here

        Desired dose(D) = 800 unis/hour.

        Dose in hand (H) = 25000 units.

            Quantity(Q) = 250 ml.

As per above formula

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

                                                     = 800 / 25000 * 250

                                                     = 0.032 * 250

                                                     = 8 ml.

                            Time(hr) = 1 hr.

                 * ml/hr = 8 ml/hr.
