Adoctor order calls for you to administer 0.1 mg of epinephrine in stock is a 1ml ampule that contains1 mg of epinephrine caculate the volume needed for this injection

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.

Let x be the number of ml you need.

Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg

(1 ml)/(1 mg) = (x ml)/(0.1 mg)

Cross multiply.

1 * x = 1 * 0.1

x = 0.1

0.1 ml

the correct answer is d

hope this
