Answer 1

ANSWER.

5) Calculation of amount required.

        Formula = Desired dose/Dose in hand * Quantity.

     Here

         Desired dose(D) = 1 mg.

         Dose in hand (H) = 10 mg.

             Quantity(Q) = 1 ml.

As per above formula

     Amount of drug required = D/H * Q

                                             = 1/10 * 1
                                             = 0.1 ml.

* Safe dose = 0.5 to 1 mg/dose.

      Weight of the patient = 4 kg.

    Safe dose for a child with 4 kg = 0.5 * 4 - 1* 4

                                                       = 2 mg - 4 mg.

    * Ordered dose(1mg) is safe for this child.

6) Calculation of amount of medication required.

           Formula = Desired dose/Dose in hand * Quantity.

       Here

           Desired dose(D) = 10 mg.

           Dose in hand (H) = 20 mg.

               Quantity(Q) = 5 ml.

    As per formula

         Amount of drug required = D/H * Q

                                                 = 10/20 * 5

                                                 = 0.5 * 5

                                                 = 2.5 ml.

* Safe dose = 10-40 mg.

    Weight of the infant = 6.7 kg.

    Safe dose for a infant with 6.7 kg = 10* 6.7 - 40 * 6.7

                                                          = 67mg - 268mg.

    * Ordered dose (10mg) is safe for this infant.

7) Calculation of amount of drug required.

             Formula = Desired dose/Dose in hand * Quantity.     

     Here

         Desired dose(D) = 100 mg.

         Dose in hand (H) = 80 mg.

                Quantity(Q) = 2 ml.

As per above formula

     Amount of drug required = D/H * Q

                                             = 100/80 * 2

                                             = 1.25 * 2

                                             = 2.5 ml.

*Safe dose = 6-7.5 mg/kg/day Q8hr.

    Weight of the child = 40 kg.

   Safe dose required for a child with 40 kg = 6*40 - 7.5 *40

                                                                     = 240 mg - 300 mg.

* Ordered dose(100mg) is safe for this child.
