In what area is an 'ophthalmic use only' medication administered?
Correct answer
B
Rationale
The correct answer is B: Conjunctival sac. Ophthalmic medications are administered into the conjunctival sac, which is the space between the lower eyelid and the eyeball. This route allows for direct absorption into the eye tissues. Administering medication into the tear duct (A) may cause systemic absorption. The sclera (C) is the white outer layer of the eye and not a typical site for medication administration. The canthus (D) is the corner of the eye where the upper and lower eyelids meet, not a location for medication administration.
