pls show all work, tu

Answer 1

Prescribed Lanoxin 0.4 mg intramuscular

Available on hand is Lanoxin 500 mcg/ 2ml

500 mcg = 0.5 mg (divide mcg with 1000 to get mg)

Required volume = required dose $\times$ availabe volume $\div$ available dose

                            = 0.4 mg $\times$ 2 ml $\div$ 0.5 mg

                            = 1.6 ml

The nurse should administer 1.6 ml of Lanoxin intramuscularly.
