A nurse is caring for a client who has a cloudy, opaque area over the lens of one eye.
The nurse should identify that this is a manifestation of which of the following visual impairments?
Cataracts.
Diabetic retinopathy.
Glaucoma.
Macular degeneration.
The Correct Answer is A
The correct answer is choice A. Cataracts are a cloudy, opaque area over the lens of one eye that can impair vision
Choice B is wrong because diabetic retinopathy is a condition that affects the blood vessels of the retina, not the lens. It can cause blurred vision, floaters, or vision loss
Choice C is wrong because glaucoma is a condition that damages the optic nerve due to high pressure in the eye. It can cause blind spots, halos around lights, or vision loss
Choice D is wrong because macular degeneration is a condition that damages the macula, the central part of the retina. It can cause blurred or no vision in the center of the visual field

These are signs of anemia, which is a condition in which the blood lacks enough healthy red blood cells to carry adequate oxygen to the body’s tissues.
Anemia can cause fatigue, weakness, pale skin, cold hands and feet, dizziness, reduced immunity and shortness of breath.
Choice A is wrong because bradypnea is abnormally slow breathing, which is not a sign of anemia. Anemia can cause tachypnea, which is abnormally fast breathing.
Choice E is wrong because flushed skin is not a sign of anemia. Anemia can cause pallor, which is pale or yellowish skin.
Flushed skin can be a sign of other conditions, such as fever, infection or allergic reaction.

Explanation
Hypothermia is a condition where the body temperature drops below 35°C (95°F) and affects the normal functioning of the body. Elderly people are more at risk for hypothermia because they have a lower muscle mass, a decreased
shiver reflex, and lower immunity. They also tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness.
Choice B. Normothermia is wrong because it means having a normal body temperature, which is around 37°C (98.6°F).
Choice C. Hyperthermia is wrong because it means having a high body temperature, which is above 37.5°C (99.5°F).
Hyperthermia can be caused by heat exposure, infection, inflammation, or certain medications.
Choice D. Malignant hyperthermia is wrong because it is a rare genetic disorder that causes a severe reaction to certain anesthetics or muscle relaxants.
It is not related to thermoregulation in elderly people.
