The nurse is reviewing the following equivalent measurements. Which of the following is a household to metric measurement?
Household Measurements
3 tsp = 1 tbsp
6 tsp = 2 tbsp
2 tbsp = 1 oz
1 tbsp = 15 mL
6 tsp = 2 tbsp
3 tsp = 1 tbsp
1 tbsp = 15 mL
2 tbsp = 1 oz
The Correct Answer is C
A. 6 tsp = 2 tbsp: This is a household-to-household conversion, converting teaspoons to tablespoons, both of which are household measurements.
B. 3 tsp = 1 tbsp: This also converts between two household units (teaspoon to tablespoon) and does not involve metric measurements.
C. 1 tbsp = 15 mL: This converts a household measurement (tablespoon) to a metric measurement (milliliters), making it a household-to-metric conversion.
D. 2 tbsp = 1 oz: Both tablespoons and ounces are household measurements, so this conversion does not involve the metric system.

Correct Answer is B
Explanation
Calculation:
The conversion factor is 1 kilogram (kg) = 1,000 grams (g).
- Convert 3 grams (g) to kilograms (kg).
Conversion (kg) = (Measurement in g / Conversion factor)
= (3 g / 1,000 g/kg)
= 0.003 kg.
Correct Answer is C
Explanation
Calculation:
Ordered Dose (D) = 15,000 units
Available Dose (H) = 40,000 units
Quantity (Q) = 1 mL
Volume (mL) = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q)
= (15,000 units / 40,000 units) x 1 mL
= 0.375 x 1 mL
= 0.375 mL
