d. Cataracts may form as a result of exposure to ultraviolet light over time.

Answer 1

Cataracts may form from continuous exposure to ultraviolet light and are common with aging, but can be prevented by wearing UV-blocking sunglasses.

Step-by-step explanation:

The nurse should respond that cataracts may form as a result of exposure to ultraviolet light over time. Cataracts are a clouding of the lens in the eye, which can lead to a decrease in vision. This condition can also be related to aging, with a significant percentage of individuals between 65 and 74 years old developing cataracts. Nutrients such as vitamins A and C are believed to provide some protection against cataract formation.

Additionally, wearing sunglasses that block UV rays, especially plastic sunglasses, can be an effective preventive measure against cataracts. Cataracts are characterized by clouding in the eye's lens and a loss of vision. Prevention is important, and eye protection from UV is more effective with plastic sunglasses than those made of glass.
