When instructed to 'instill', what is the common method of administration?

The term 'instill' refers to the method of administering a liquid substance, typically in the form of drops, into a specific area of the body. This is commonly done with medications in the form of eye drops, ear drops, or nose drops. The objective is to deliver the medication directly into the targeted area, allowing for effective absorption where it is needed most.

In contrast, the other methods listed involve different routes of administration. Taking something orally means ingesting it, which is not aligned with the precision intended by instillation. Inhaling refers to administering a substance into the lungs, while topical application involves spreading or applying a substance onto the skin. Both of these routes differ significantly from the direct drop-based method used in instillation.
