What is the metric equivalent of 1 tablespoon?
15 mL
5 mL
10 mL
30 mL
The Correct Answer is A
A. 15 mL: One tablespoon is equivalent to 15 milliliters in the metric system, which is the standard conversion used in clinical practice for accurate measurement of liquid medications.
B. 5 mL: This volume corresponds to one teaspoon, not a tablespoon, and using it would underdose the patient if a tablespoon is required.
C. 10 mL: Ten milliliters does not equal a tablespoon. Administering this amount would result in an insufficient dose.
D. 30 mL: Thirty milliliters corresponds to approximately 2 tablespoons or 1 fluid ounce, which would double the intended dose if used incorrectly.

Correct Answer is C
Explanation
A. Each small line indicates 5 units of insulin: This is inaccurate because a U-100 insulin syringe has smaller graduations for precise dosing, and 5-unit increments would not allow accurate measurement of single-unit doses.
B. Each small line indicates 2 units of insulin: While closer, most U-100 syringes are marked in single-unit increments, making 2-unit interpretation insufficiently precise for safe insulin administration.
C. Each small line indicates 1 unit of insulin: Each small line represents 1 unit, allowing precise measurement of insulin doses. This accuracy is crucial for patient safety, especially when administering doses that are not multiples of five.
D. Each small line indicates 0.5 units of insulin: U-100 syringes are not typically marked in half-unit increments. Using this interpretation could lead to under- or overdosing, particularly in standard adult dosing.
Correct Answer is B
Explanation
A. It is based on units of 10: The metric system, not the apothecary system, is based on units of 10. This allows for easy conversion between units like grams, liters, and meters.
B. It uses Roman numerals and fractions: The apothecary system often uses Roman numerals and fractional notation (e.g., ℥ for ounces, ℨ for dram) to indicate quantities. This differs from the metric system’s decimal-based, standardized measurements and is less commonly used today due to complexity.
C. It is the most commonly used system in healthcare today: The metric system is the standard in modern healthcare for medication dosing and measurements. The apothecary system is largely historical and rarely used.
D. It measures exclusively in milliliters: Measuring exclusively in milliliters is a feature of the metric system, not the apothecary system. Apothecary measurements include units like grains, drams, and ounces rather than standardized metric volumes.
