Answer 1

a. Order was Streptomycin 0.25gm = 250 mg

b. The available medication is in a concentration of 400mg/2ml

c. The required volume of medication = required dose $\times$ available volume $\div$ available dose

                                                       = 250 $\times$ 2 $\div$ 400

                                                       = 1.25 or 1.3 (rounded)

We must administer 1.3 ml of reconstituted streptomycin which contains 0.25gm or 250mg dose.
