Final answer:
A medical assistant should use a sterile, single-use applicator to apply the medication for conjunctivitis. Tap water should be avoided, and the medication should be applied to the lower conjunctival sac.
Step-by-step explanation:
When performing an eye installation for a patient with conjunctivitis, a medical assistant should:
- Use a sterile, single-use applicator to apply the medication. This helps prevent the spread of infection and ensures cleanliness.
- Avoid irrigating the eye with tap water as it can introduce more bacteria and irritants.
- Apply the medication to the lower conjunctival sac by gently pulling the lower eyelid down and putting the drops or ointment in the space between the eyelid and the eye.
