If a prescription calls for 45 mL, what is the equivalent amount in tablespoons?

To determine the equivalent amount of 45 mL in tablespoons, we can use the conversion factor that 1 tablespoon is approximately equal to 15 mL. By dividing 45 mL by 15 mL/tablespoon, we find that 45 mL is equivalent to 3 tablespoons.

This conversion is significant in pharmacy since accurate dosing often requires converting measurements between different units, such as milliliters, teaspoons, and tablespoons. Understanding these conversions is critical for a pharmacy technician when preparing medications for patients, ensuring proper dosage and efficacy.

Other measurements in the question do not align with the correct conversion. For instance, 1 tsp is approximately 5 mL, making it too small; 2 tsp would equal about 10 mL, which is still insufficient; and 4 tbsp would translate to 60 mL, exceeding the required amount. Therefore, the calculation confirming that 3 tablespoons is equivalent to 45 mL reinforces the accuracy required in medication dispensing and underscores the importance of being familiar with measurement conversions.
