The patient has atropine gr 1/120 ordered. The label reads atropine 400mcg/ml. How many ml will you give?

    1/120 g = .008333 g = 8.3 mg
    1 mg = 1000 mcg
    So you want 8333 mcg / 400 = 20.833
    21 is closest whole number, 20 is the closest round number.
    20 * 400 = 8000 mcg = 8 mg = 1/125 g, slightly less than the stated dose.
