A nurse knows teaching has been effective when the client states the following:
A) "If my sensitivity to glare decreases and my contrast sensitivity increases, I will be evaluated for cataracts."
B) "I wear sunglasses and a wide-brimmed hat when I am in the sun to protect my eyes and prevent the development of cataracts."
C) "Having Alzheimer disease increases one's risk of developing macular degeneration."
D) "If I take ototoxic medications, this will increase my risk for developing cataracts."
Ans: B
Protecting one's eyes from sunlight is a health promotion intervention for preventing cataracts. Cataract symptoms include increased sensitivity to glare and decreased contrast sensitivity. Individuals with Alzheimer disease may have impaired contrast sensitivity and other visual impairments, but not an increased risk of developing macular degeneration. Ototoxic drugs will damage the auditory nerve; they do not affect the optic nerve or vision.
