For which preparation is an oral dropper typically used?

An oral dropper is typically used for liquid medications up to 5ml because it allows for precise measurement and dosing of small amounts of liquid. This is particularly important when administering medications that require careful dosing, such as those for children or when the dosage is measured in milliliters.

Using a dropper ensures that the correct amount is delivered, which is crucial for efficacy and safety. Liquid medications are often formulated to be taken directly by mouth, and a dropper enables users to easily administer these medications without spilling or over-dosing.

The other options do not align with the primary purpose of an oral dropper. Solid medications, such as tablets or capsules, cannot be measured or administered effectively with a dropper. Therefore, the use of an oral dropper is specifically suited for liquid medications, especially those in smaller volumes.
