Question

A physician orders FRAGMIN 7,500 units subcutaneously stat and daily. Available in stock are 9-mL vials of FRAGMIN (DALTEPARIN) 10,000 international units/mL. How many mL should be administered per dose?

a. 3.8

b. 0.75

c. 0.38

d. 7.5

Answer 1

Solution.

we have given 9 ml  vials in which FRAGMIN is 10,000 units/ml

that is, 10,000 units of FRAGMIN in 1ml

now we need to find for 7500 units of FRAGMIN how many ml of liquid(available in the vial) we need to give

or 7500 ml of FRAGMIN is available in how many ml.

10,000 units in 1ml

7500 units in = 7500 x( 1/10,000) ml =0.75 ml

hence, we need to give 0.75 ml per dose.
