What is the correct distance a nurse should hold an ophthalmic solution above the lower conjunctival sac for administration?

The correct distance for administering an ophthalmic solution above the lower conjunctival sac is typically 2 cm. This specific distance is recommended to ensure that the medication is delivered effectively into the conjunctival sac without causing discomfort or improper administration.

Holding the dropper at this distance allows for the drop of the medication to fall accurately into the sac, which helps to promote optimal absorption of the medication into the eye. If the dropper is held too close, there is a risk of the medication not being instilled properly or the dropper touching the eye, which can lead to contamination. Conversely, holding it too far away may result in the drop missing the conjunctival sac altogether, thereby reducing the effectiveness of the treatment.

This technique is critical in nursing practice and ensures that eye medications are administered safely and effectively, maximizing therapeutic benefit for the patient.
