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

Correct Answer is C
Explanation
Splenomegaly and jaundice are signs of hemolytic anemia, a disorder in which red blood cells are destroyed faster than they are made.
Splenomegaly is an enlargement of the spleen, which may trap and destroy healthy red blood cells. Jaundice is a yellowing of the skin and eyes caused by the buildup of bilirubin, a waste product of hemoglobin breakdown. Choice A is wrong because red, sore tongue is a sign of vitamin B12 deficiency anemia, not hemolytic anemia.
Choice B is wrong because pica is a craving for nonfood items, such as ice, dirt, or starch. It is a sign of iron deficiency anemia, not hemolytic anemia. Choice D is wrong because paresthesias are sensations of tingling, numbness, or prickling in the hands or feet. They are a sign of pernicious anemia, a type of vitamin B12 deficiency anemia, not hemolytic anemia.
Normal ranges for red blood cell count are 4.5 to 5.9 million cells per microliter for men and 4.1 to 5.1 million cells per microliter for women. Normal ranges for hemoglobin are 13.5 to 17.5 grams per deciliter for men and 12.0 to 15.5 gramsper deciliter for women. Normal ranges for bilirubin are 0.1 to 1.2 milligrams per deciliter for adults.

Choice C. Justice is the ethical principle of treating clients fairly and equally.
It means that the nurse should distribute resources and services based on the client’s needs and not on personal biases.
Choice D. Autonomy is the ethical principle of respecting a client’s right to make their own decisions.
