Answer 1

ANSWER.

2) a) Weight of the patient in kg.

            Weight of the patient in lbs = 92 lbs.

      Convert lbs to kg

               1 lbs = 0.454 kg

So

     Weight of the patient in kg = 92 * 0.454

                                                = 41.7 kg.

b) Safe dose range.= 2-5 mg/kg/dose.

c) is order safe.

          Safe dose range = 2 to 5 mg/kg/dose.

         Weight of the patient = 41.7 kg.

     Safe dose recommended for a patient weight 41.7 kg = 2 * 41.7 to 5 * 41.7

                                                            = 83.4 mg to 208.5 mg per dose.

         Ordered dose = 70 mg bid or twice a day.

                                = 70 mg per dose.

    So

        The ordered dose (70 mg) is low or underdose when compared to the recommended

        safe dose (83.4 mg to 208.5 mg).
