When converting 3 ounces of medication to milliliters, what is the correct conversion?

Rationale:
A. Divide by 1000: To convert milliliters (mL) to liters (L), the value in milliliters is divided by 1000 because 1 liter equals 1000 milliliters. Therefore, 1500 mL ÷ 1000 = 1.5 L, which provides the correct volume in liters.

B. Multiply by 1000: Multiplying by 1000 would convert liters to milliliters, not the other way around.

C. Divide by 100: Dividing by 100 converts centiliters to liters, not milliliters.

D. Multiply by 100: Multiplying by 100 is used for converting from liters to centiliters, not for converting milliliters to liters.

Rationale:
A. ts: "Ts" is not a standard abbreviation for teaspoon in the household system and may cause confusion with other measurements. Using incorrect abbreviations increases the risk of dosing errors.

B. tbl: "Tbl" typically represents tablespoon, which is a larger volume than a teaspoon. Confusing these units could lead to a significant dosing error.

C. tsp: "Tsp" is the standard abbreviation for teaspoon in the household measurement system. It ensures clarity when measuring small volumes of medication or ingredients, promoting accurate administration.

D. t: Using "t" alone is ambiguous and not a recommended abbreviation for teaspoon. Standardized abbreviations like "tsp" prevent misinterpretation and ensure patient safety.
