Answer 1

ANSWER.

1) a) Calculation of mg of drug required.

                Ordered dose = 350 mg bid

         bid is two times a day

    So

       mg of drug required per day = 350 * 2

                                                    = 700 mg per day.

2) Calculation of volume(ml) of drug required.

        Volume(ml) = Desired dose(D)/D0se in hand(H) * Quantity(Q).

    Here

       Desired dose(D) = 350 mg.

       Dose in hand(H) = 250 mg.

            Quantity(Q) = 5 ml

As per above formula

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

                                                   = 350/250 * 5

                                                   = 1.4 * 5

                                                   = 7 ml bid.

3) Calculation of volume(ml) of drug required.

         Volume(ml) = Desired dose(D)/Dose in hand(H) * Quantity(Q)

    Here

         Desired dose(D) = 0.5 mg.

         Dose in hand(H) = 0.1 mg.

              Quantity(Q) = 1 ml

As per above formula

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

                                                      = 0.5/0.1 * 1

                                                      = 5 * 1

                                                      = 5 ml.

4) Calculation of ml of drug required.

            Volume(ml) = Desired dose(D)/Dose in hand(H) * Quantity(Q)

      Here

          Desired dose(D) = 80 mEq.

          Dose in hand(H) = 40 mEq.

               Quantity(Q) = 30 ml

As per above formula

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

                                                    = 80/40 * 30

                                                    = 2 * 30

                                                    = 60 ml.
