Answer to Question 1
Answer: A
Age is the greatest single risk factor for cataracts. Environmental and lifestyle factors, such as long-term exposure to sunlight, increase the risk for cataracts; cigarette smoking and heavy alcohol consumption are associated with earlier cataract development. Eye trauma, including injury to the lens capsule by a foreign body, blunt trauma, or exposure to heat or radiation, can precipitate cataract formation. Diabetes mellitus is associated with earlier development of cataracts, especially when the blood glucose level is not carefully controlled at or near normal levels. Certain drugs, such as systemic or inhaled corticosteroids, chlorpromazine (Thorazine), and busulfan (Myleran), also prompt the formation of cataracts. The one assessment finding that would predispose the client to cataract formation is the client's age. The other findings would not.
Answer to Question 2
Answer: B
The nurse should respond that cataracts tend to occur in both eyes and develop at different rates, and one cataract generally matures more rapidly than the other. The nurse should not tell the client that the healthcare provider made an error or that the healthcare provider is the only one who can tell if the client has a cataract in the left eye. The nurse should not tell the client not to worry until vision is lost in the left eye.
