Final answer:
Before administering eye drops to a child with conjunctivitis, the nurse should cleanse the eye to remove any exudate.
Step-by-step explanation:
When caring for a 6-year-old client with conjunctivitis, it is essential for the nurse to cleanse the eye with warm water, removing any exudate, before administering eye drops. This practice is vital as it ensures the medication can be administered effectively and reduces the risk of further irritation or infection. It is generally not appropriate for the child to instill his own eyedrops due to the risk of improper administration, and while a mother can assist, it is the responsibility of the nurse to ensure the medication is given correctly. Holding the medication merely because the eye appears clear is not advisable, as conjunctivitis can present with varying symptoms, and treatment should follow the prescribed schedule unless a doctor advises otherwise.
