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 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.

Correct Answer is ["0.7"]
Explanation
To calculate the dosage of diphenhydramine injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 35 mg, H is 50 mg/mL, and Q is 1 mL.
Plugging these values into the formula, we get:
35 mg / 50 mg/mL x 1 mL = 0.7 mL
Therefore, the nurse should administer 0.7 mL of diphenhydramine injection.
Correct Answer is ["2"]
Explanation
To calculate the number of tablets needed to administer promethazine 25 mg PO, the nurse should use the following formula:
(number of tablets) = (desired dose) / (available dose)
Substituting the values given in the question, we get:
(number of tablets) = (25 mg) / (12.5 mg)
Simplifying, we get:
(number of tablets) = 2
Therefore, the nurse should administer 2 tablets of promethazine 12.5 mg to the client.
