Answer to Question 2
ANS: 3
Eye drops should be instilled into the lower conjunctival sac. The conjunctival sac normally holds 1 or 2 drops and provides even distribution of medication across the eye. The cornea is very sen-sitive. If drops were instilled onto the cornea it would stimulate the blink reflex. The outer can-thus would not hold the eye drop, medication would be wasted, and it would not be distributed evenly across the eye. The opening of the lacrimal duct is not the correct site for eye drops to be instilled. It would not provide even distribution of drops across the eye, and medication would most likely be wasted because this area could not contain the drops.
