Answer 1

ANSWER

1.Calculation of amount(ml) of Amoxicillin will be needed.

        Formula = Desired dose / Dose in hand * Quantity.

           Here

               Desired dose (D) = 50 mg.

             Dose in hand (H) = 125 mg.

                      Quantity (Q) = 5 ml.

            As per formula

                Amount (ml) of Amoxicillin needed = D / H * Q

                                                                           = 50 / 125 * 5

                                                                           = 0.4 * 5

                                                                           = 2 ml.

2. Calculation of amount(ml) of phenobarbital needed.

        Formula = Desired dose / Dose in hand * Quantity.

       Here   

                Desired dose(D) = 5 mg.

                Dose in hand (H) = 20 mg.

                      Quantity (Q)   = 5 ml.

     As per formula

         Amount of Phenobarbital needed = D / H * Q

                                                            = 5 / 20 * 5

                                                              = 0.25 * 5

                                                                = 1.25 ml.

3. Calculation of amount(ml) of EES needed.

         Formula = Desired dose / Dose in hand * Quantity.

           Here

                Desired dose(D) = 400 mg.

                Dose in hand(H) = 125 mg.

                   Quantity(Q) = 5 ml.

      As per formula

           Amount (ml) of EES required = D / H * Q

                                                             = 400 / 125 * 5

                                                         = 3.2 * 5

                                                           = 16 ml.

4. Calculation of amount(ml) of Aminophylline required.

          Formula = Desired dose / Dose in hand * Quantity.

            Here

                   Desired dose (D) = 50 mg.

                   Dose in hand (H) = 250 mg.

                          Quantity (Q) = 10 ml.

        As per formula

           Amount(ml) of Aminophylline required = D / H * Q

                                                                             = 50 / 250 * 10

                                                                       = 0.2 * 10

                                                                       = 2 ml.

5. Calculation of amount(ml) of Amoxicillin required.

        Formula = Desired dose / Dose in hand * Quantity.

             Desired dose (D) = 200 mg.

             Dose in hand (H) = 250 ml.

                     Quantity(Q) = 5 ml.

As per formula

               Amount (ml) of Amoxicillin required = D / H * Q

                                                                = 200 / 250 * 5

                                                                = 0.8 * 5

                                                                  = 4 ml.

6. Calculation of amount(ml) of solumetrol required.

         Formula = Desired dose / Dose in hand * Quantity.

           Here

           Desired dose (D) = 3mg/kg

                  Patient weight = 20 kg.

          So

             Desired dose (D) = 3 * 20

                                          = 60 mg.

             Dose in hand (H) = 25 mg.

                 Quantity (Q) = 2 ml.

    As per formula

            Amount(ml) of solumetrol required = D / H * Q

                                                                  = 60 / 25 * 2

                                                                      = 2.4 * 2

                                                                      = 4.8 ml.
