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.)

Step 1: Identify the given information: Concentration of insulin glargine: 100 units/mL Volume of the vial: 10 mL Step 2: Calculate the total number of units in the vial: Total units = Concentration (units/mL) x Volume (mL) Step 3: Substitute the values: Total units = 100 units/mL x 10 mL Step 4: Calculate the result: Total units = 1000 units Step 5: Calculate the number of doses: Number of doses = Total units / Dose per dose Step 6: Substitute the values: Number of doses = 1000 units / 10 units/dose Step 7: Calculate the result: Number of doses = 100 doses
