Which assessment alerts the nurse to the possible presence of a cataract in a client?
a. Loss of central vision
b. Loss of peripheral vision
c. Dull aching in the eye and brow areas
d. Blurred vision and reduced color percep-tion
D
As the lens becomes opaque and less able to refract light appropriately, the client experiences blurred vision and a reduced ability to distinguish among different colors. The development of a cataract does not typically cause loss of peripheral or central vision, nor does it result in aching in the brow area.
