Which statement about administering eye ointment is true?

The statement that administering eye ointment should be instilled in the lower conjunctival sac is accurate and reflects proper technique for applying eye medications. The lower conjunctival sac is the space between the lower eyelid and the eyeball where medication can be inserted with minimal risk of irritation or injury to the eye itself. By applying the ointment there, it allows for better absorption and reduces the risk of contaminating the surface of the eye.

Administering ointment into the lower conjunctival sac also helps the medication stay in contact with the eye longer, allowing for a more effective treatment while minimizing potential discomfort. It's important for patients to understand this method to ensure that they are applying the medication correctly for optimal benefit and safety.
