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"]
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

Correct Answer is ["1.6"]
Explanation
Given:
Ordered dose: 480 mcg filgrastim
Available concentration: 300 mcg/mL
To find:
Volume to administer (mL)
Calculation:
We need to find the volume that contains 480 mcg of filgrastim.
We can achieve this by dividing the ordered dose (480 mcg) by the concentration (300 mcg/mL).
Volume (mL) = Ordered dose (mcg) / Concentration (mcg/mL)
Volume (mL) = 480 mcg / 300 mcg/mL
Round the answer to the nearest tenth:
Volume (mL) = 1.6 mL (rounded)
Answer:
The nurse should administer 1.6 mL of filgrastim injection per dose.
Correct Answer is C
Explanation
A) ML: This abbreviation stands for milliliters, which is a metric unit of volume used to measure liquids, not weight. It is essential for the newly hired nurse to distinguish between units of volume and weight to ensure accurate documentation in the medical record.
B) OZ: This abbreviation stands for ounces, which is a unit of weight commonly used in the imperial system, not in the metric system. Understanding this difference is crucial for accurate documentation of weights, especially in contexts where metric units are required.
C) mcg: This abbreviation stands for micrograms, which is a metric unit of weight used to measure very small amounts of substances, such as medications. Recognizing this abbreviation is important for precise medication administration and documentation.
D) Lb: This abbreviation stands for pounds, which is a unit of weight commonly used in the imperial system, not typically considered a metric unit of weight. Differentiating between imperial and metric units ensures proper documentation and compliance with healthcare standards.
