A nurse is helping an assistive personnel with documenting a client's fluid intake in the medical record. Which of the following values should the nurse identify as a metric unit?
8 Tbsp
4 oz
120 mL
0.5 cup
The Correct Answer is C
A. 8 Tbsp: Tablespoons are household units commonly used in cooking and informal settings. They are not part of the metric system used in clinical documentation.
B. 4 oz: Ounces are part of the imperial system, not the metric system. While fluid ounces are often used in the U.S., they are not classified as metric units.
C. 120 mL: Milliliters (mL) are metric units of volume and are the standard for documenting fluid intake in healthcare settings. 120 mL is a precise metric measurement.
D. 0.5 cup: Cups are household measurements and not part of the metric system. While commonly used in dietary references, they must be converted to mL for clinical documentation.

Correct Answer is ["0.1"]
Explanation
Calculation:
Desired dose = 100 mcg.
Available concentration = 1,000 mcg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 100 mcg / 1,000 mcg/mL
= 0.1 mL.
Rounded to the nearest tenth: 0.1.
Correct Answer is ["50"]
Explanation
Calculation:
Identify the total daily dose.
Total daily dose = 200 mg.
Determine the frequency of doses per day.
Doses per day = 24 hours / 6 hours/dose
= 4 doses.
Calculate the dose per administration.
Dose per administration = Total daily dose / Doses per day
= 200 mg / 4 doses
= 50 mg.
Rounded to the nearest whole number: 50.
