A nurse is reinforcing teaching with a newly hired nurse about documentation in the medical record. Which of the following abbreviations should the newly hired nurse identify as a metric unit of weight?
ML
OZ
mcg
Lb
The Correct Answer is C
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.

Correct Answer is ["2"]
Explanation
The nurse should administer 2 mL of diazepam injection
Here's the calculation:
Desired dose: 10 mg
Concentration of available diazepam: 5 mg/mL
We can find the volume to administer by dividing the desired dose by the concentration and rounding to the nearest whole number:
Volume to administer (rounded) = Dose / Concentration
= 10 mg / (5 mg/mL)
= 2 mL (rounded to nearest whole number)
Therefore, the nurse should administer 2 mL of the diazepam injection.
Correct Answer is ["3.00"]
Explanation
The nurse should administer 3 tablets of calcium carbonate per dose.
Here's the breakdown:
Daily dose: 3.9 g
Dose frequency: Every 12 hours (meaning two doses per day)
Tablet strength: 650 mg per tablet
Step 1: Convert daily dose to milligrams
Since tablets are typically measured in milligrams (mg), we need to convert the daily dose from grams (g) to milligrams (mg). There are 1000 milligrams in one gram:
Daily dose (mg) = 3.9 g x 1000 mg/g
= 3900 mg
Step 2: Calculate the dose per administration
Since the total daily dose is given to be administered in equally divided doses every 12 hours, we need to find the amount to be administered per dose
Dose per administration = Daily dose / Number of doses per day
= 3900 mg / 2 doses/day
= 1950 mg
Step 3: Find the number of tablets per dose
Now, we can determine how many tablets are needed to deliver the calculated dose per administration.
We can divide the dose per administration by the strength of each tablet (rounding to the nearest whole number):
Number of tablets (rounded) = Dose per administration / Tablet strength
= 1950 mg / 650 mg/tablet
= 3.00 tablets (round to 3)
