Answer #1

ANSWER.

* Calculation of amount(ml) of drug required.

       Formula = Desired dose/Dose in hand * Quantity.

     Here

         Desired dose (D) = 0.24 mg.

     Convert mg to mcg for calculation

                    1mg = 1000 mcg.

      So

               Desired dose (D) = 0.24 * 1000

                                            = 240 mcg.

         Dose in hand (H) = 50 mcg.

               Quantity (Q) = 1 ml.

As per above formula

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

                                                   = 240 / 50 * 1

                                                   = 4.8 ml.
