Final answer:
Seeing flashing lights and floaters post-cataract surgery could indicate a risk of retinal detachment, which is an emergency situation. Cataracts, a cause of blindness due to lens clouding, can be corrected with surgery and prevented with UV protection sunglasses.
Step-by-step explanation:
If a client who has previously undergone cataract surgery reports seeing flashing lights and floaters in the eye, the nurse may interpret that the client is at risk of a retinal detachment. This is because the symptoms described are classic signs that can indicate a tear or detachment of the retina, which can occur after the type of surgery they have had. This is a medical emergency and should be assessed by an ophthalmologist immediately. Cataracts, which are caused by a clouding of the lens of the eye, can lead to blindness if untreated but can be corrected by replacing the lens with a plastic one. Wearing UV protection sunglasses, especially those made of plastic, is also important for preventing the formation of cataracts.
