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 ["75"]
Explanation
The medication label for amoxicillin powder provides the instructions for reconstituting the oral suspension. The nurse should follow these steps:
- Tap the bottle until all the powder is loose.
- Add about 17 mL of water to the bottle (one-third of the total amount of 51 mL).
- Shake the bottle well to mix the powder and water.
- Add the remaining 34 mL of water to the bottle and shake again.
- Check that the final volume of the oral suspension is 75 mL.
The nurse should expect the bottle to contain 75 mL of oral suspension after reconstitution.
This is because each 5 mL of oral suspension contains 400 mg of amoxicillin, and the net contents of the powder are equivalent to 6 grams (6000 mg) of amoxicillin.
Therefore, 6000 mg / 400 mg = 15, which means that 15 doses of 5 mL each are needed to use up all the powder. Multiplying 15 by 5 mL gives 75 mL, which is the final volume of the oral suspension.
Correct Answer is ["1.8"]
Explanation
To calculate the correct dosage of gentamicin for a client who weighs 154 lb, the nurse needs to perform the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2. 154 lb / 2.2 = 70 kg.
- Multiply the client's weight in kilograms by the prescribed dose of 1 mg/kg. 70 kg x 1 mg/kg = 70 mg.
- Divide the total dose in milligrams by the concentration of the gentamicin solution, which is 40 mg/mL. 70 mg / 40 mg/mL = 1.75 mL.
Round the final answer to the nearest tenth of a milliliter. The nurse should administer 1.8 mL of gentamicin IM to the client.
