A nurse is preparing to administer insulin glargine to a child who has type 1 diabetes mellitus. The client is to receive 10 units subcutaneous once daily at bedtime. Reading the label on the unopened vial, the nurse should determine that the vial contains how many doses of this medication? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["100"]

To determine the number of doses in the vial, we can use the information provided on the label. The vial contains 10 mL of insulin glargine, and each mL has a concentration of 100 units.

Number of units in the vial = Concentration * Volume

Number of units in the vial = 100 units/mL * 10 mL

Number of units in the vial = 1000 units

Therefore, the vial contains 1000 units of insulin glargine. Since the client is to receive 10 units per dose, we can calculate the number of doses:

Number of doses = Total units in the vial / Units per dose

Number of doses = 1000 units / 10 units/dose

Number of doses = 100 doses

So, the vial contains 100 doses of insulin glargine.
