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.)

The label on the vial indicates that the insulin glargine has a concentration of 100 units per milliliter (U-100) and the total volume of the vial is 10 mL. To calculate the total number of units in the vial, you multiply the volume by the concentration: Total units = Volume × Concentration = 10 mL×100 units/mL = 1000 units Then, to find out how many doses of 10 units each are in the vial, you divide the total number of units by the number of units per dose: Number of doses = Total units/ Units per dose ​ = 1000 units /10 units per dose ​ = 100 doses So, the vial contains 100 doses of this medication when administered at 10 units per dose
