Question

Insulin comes in 10 cubic centimeter (cc) vials labeled in the numbers of units of insulin per cubic centimeter of fluid. A vial marked U40 has 40 units of insulin per cubic centimeter of fluid. If a patient needs 24 units of insulin, how much fluid should be drawn into the syringe from the U40 vial?

The amount of fluid containing 24 units of insulin is __CC.

a) 2.4 CC
b) 4.8 CC
c) 6.0 CC
d) 9.6 CC

Answer 1

To get 24 units of insulin from a U40 vial, the calculation 24 units * 1 cc / 40 units = 0.6 cc shows that 0.6 cubic centimeters of fluid should be drawn into the syringe.

Step-by-step explanation:

If a patient needs 24 units of insulin and the vial is U40 (meaning it has 40 units of insulin per cubic centimeter of fluid), we calculate the amount of fluid needed using a simple proportion. Since one cc contains 40 units, we set up the following ratio: 40 units / 1 cc = 24 units / X cc. Solving for X gives us X = (24 units * 1 cc) / 40 units = 0.6 cc.

Therefore, to get 24 units of insulin from a U40 insulin vial, 0.6 cubic centimeters of fluid should be drawn into the syringe. The correct answer is: The amount of fluid containing 24 units of insulin is 0.6 CC.

To find the amount of fluid containing 24 units of insulin, you can use the relationship given by the concentration of the insulin solution. In this case, the U40 vial has 40 units of insulin per cubic centimeter of fluid.
