Sergio [31]

Answer:

<em>8.25 cc fluid should be drawn into the syringe from the U40 vial.</em>

Step-by-step explanation:

The amount of a U40 vial insulin fluid is 10 cc.

A vial marked U40 has 40 units of insulin per cubic centimeter of fluid.

Suppose, if a patient needs 33 units of insulin, then x cc fluid should be drawn.

So, <u>according to the ratio of "cubic centimeter" to "the units of insulin"</u>, the equation will be.........

\frac{x}{33}=\frac{10}{40}\\ \\40x=330\\ \\ x=\frac{330}{40}=8.25

So, 8.25 cc fluid should be drawn into the syringe from the U40 vial.
