A nurse is reviewing a client's instructions for their prescribed medications. The nurse should identify that which of the following instructions contains household units?
Take 250 mg by mouth twice daily.
Mix powder with 1 L of water and drink throughout the day.
Dissolve one packet in 120 mL and drink twice daily.
Take 1 Tbsp by mouth after every meal.
The Correct Answer is D
A. Take 250 mg by mouth twice daily: This instruction uses metric units (milligrams) to describe the medication dosage, not household measurement units.
B. Mix powder with 1 L of water and drink throughout the day: Liters are part of the metric system, commonly used in clinical settings, and do not represent household measurement units.
C. Dissolve one packet in 120 mL and drink twice daily: Milliliters are metric units. Although they may be converted for home use, they are not considered standard household units.
D. Take 1 Tbsp by mouth after every meal: This instruction uses a household unit—tablespoon (Tbsp)—which is commonly used everyday in medication instructions at home. One tablespoon is equal to 15 mL, making it a recognizable and practical measure for clients managing their medications outside of clinical settings.

Identify the desired dose.
Desired dose = 480 mcg.
Identify the available concentration.
Available concentration = 300 mcg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 480 mcg / 300 mcg/mL
