What does the term "gtt" represent in medication dosage?

The term "gtt" is a Latin abbreviation for "gutta," which means "drop." In the context of medication dosage, it specifically refers to drops of liquid medication. This unit of measurement is often used in ophthalmology for eye drops, where precise dosing is crucial for patient care. Health professionals frequently communicate dosages in terms of drops, especially when dealing with liquid medications that need to be administered in small amounts.

The other options represent different units of measurement that are not applicable in this context. For instance, "gram" is a unit used for measuring weight, "tablet" refers to a solid dosage form of medication, and "ounce" is a volume measure that is not typically used for the precise dosing of liquid medications like eye drops. Understanding that "gtt" means drop reinforces the need for accuracy in the administration of medications, particularly in the sensitive field of ophthalmology.
