If a patient requires 20 mL of codeine oral solution, how many teaspoons should be administered?

To determine the correct number of teaspoons for 20 mL of codeine oral solution, it’s important to know the conversion between milliliters and teaspoons.

1 teaspoon is equivalent to approximately 5 milliliters. To convert milliliters to teaspoons, you divide the number of milliliters by the number of milliliters in one teaspoon.

So, for 20 mL:

• You take 20 mL and divide it by 5 mL/tsp, which equals 4 teaspoons.

This calculation aligns with the requirement for the patient and confirms that 20 mL corresponds to 4 teaspoons. Therefore, administering 4 teaspoons is accurate and supports proper dosing of the medication.
