Final answer:
The nurse monitors for double vision in the right eye in a patient diagnosed with a cataract.
Step-by-step explanation:
Cataracts refer to the clouding of the natural lens in the eye, which leads to a progressive loss of vision. The lens is a clear structure situated behind the iris (colored part of the eye) that helps focus light onto the retina, allowing us to see sharp images. When cataracts develop, the lens becomes opaque or cloudy, affecting the passage of light and causing visual impairment.
The nurse monitors for double vision in the right eye in a patient diagnosed with a cataract. Double vision, also known as diplopia, is a common clinical manifestation of cataracts. The cloudiness in the lens of the eye can cause the light entering the eye to scatter, resulting in vision abnormalities such as double vision.
