A nurse is caring for a patient who has a cloudy, opaque area over the lens of one eye. Which of the following visual impairments should the nurse identify this as a symptom of?
Glaucoma.
Diabetic retinopathy.
Macular degeneration.
Cataract.
The Correct Answer is D
Choice A rationale
Glaucoma is a condition that damages the eye’s optic nerve and can result in vision loss and blindness. However, it doesn’t cause a cloudy, opaque area over the lens of the eye.
Choice B rationale
Diabetic retinopathy is a diabetes complication that affects eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). But it doesn’t cause a cloudy, opaque area over the lens of the eye.
Choice C rationale
Macular degeneration is a medical condition which may result in blurred or no vision in the center of the visual field. But it doesn’t cause a cloudy, opaque area over the lens of the eye.
Choice D rationale
A cataract is a clouding of the lens in the eye that affects vision. Cataracts are very common in older people. Symptoms of cataracts include cloudy or blurry vision.
