The nurse is caring for a school-age child with crusting and swollen eyelids, purulent drainage, and inflamed conjunctiva. The child receives a prescription for an ophthalmic antiinfective ointment. Which instruction should the nurse provide the child's caregivers during discharge education?

A. Discontinue the ointment once drainage resolves. The ophthalmic antiinfective ointment should be used for the full prescribed duration, even if symptoms improve, to ensure the infection is completely treated and to prevent recurrence or resistance. B. Remove secretions by wiping toward the opposite eye. Secretions should be removed by wiping away from the eye, from the inner canthus (near the nose) outward, to prevent spreading infection to the unaffected eye. C. Use a disposable moist wipe to remove eye crusts. While it is important to keep the eye clean, the primary discharge instruction in this context should focus on the expected side effect of blurry vision. D. Prepare child for blurry vision after ointment application: Ophthalmic antiinfective ointments can cause temporary blurry vision due to their consistency. Caregivers should be informed about this expected effect and reassured that it is temporary. This helps manage expectations and ensures adherence to the treatment plan.
