Answer 1

ANSWER.

* Calculation of haloperidol dose.

       * Ordered dose = 1.2 mg/kg.

      * Patient body weight = 198 pounds.

Convert pound value to kg for calculation.

             1 pound = 0.454 kg.

So

      Patient body weight in kg = 198 * 0.454

                                               = 89.8 kg.

      Dose required for patient weight 198 pounds = 1.2 * 89.8

                                                                           = 107.76 mg.

                                                                           = 108 mg.

          * Inj.Haloperidol.

                  * Dose = 108 mg.

                  * Route = Intramuscular (IV).

                  * Frequency = Once every month.
