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.

Answer and Explanation

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 A

Explanation

This helps increase the oxygen-carrying capacity of the blood and corrects anemia.

Choice B is wrong because erythropoietin is not given to all people with anemia. It is only used for certain types of anemia, such as those caused by chronic kidney disease or chemotherapy.

Choice C is wrong because erythropoietin is not given for iron deficiency anemia. Iron deficiency anemia is treated with iron supplements and dietary changes.

Choice D is wrong because erythropoietin does not stimulate bone marrow production of white blood cells. White blood cells are involved in immune responses and are produced by different growth factors.

Question 22.

A. Keep call bell within the client’s reach. B. Keep a dim light on at night. C. Keep unnecessary furniture out of the way. D. Keep all side rails up at all times. E. Keep all lights off at night.

Correct Answer is ["A","B","C"]

Explanation

These actions ensure the safety of the client by reducing the risk of falls, confusion and injury.

Keeping a call bell within the client’s reach allows them to ask for help when needed.

Keeping a dim light on at night helps them orient themselves and see their surroundings.

Keeping unnecessary furniture out of the way prevents tripping and cluttering. Choice D is wrong because keeping all side rails up at all times can be considered a form of physical restraint, which is associated with many professional, legal and ethical challenges. Physical restraint should only be used as a last resort when other alternatives have failed or are not feasible. Keeping all side rails up can also increase the risk of injury if the client tries to climb over them.

Choice E is wrong because keeping all lights off at night can increase the risk of falls and confusion for the client.

Older adults may have impaired vision and cognition, and they may need to use the bathroom frequently at night. Keeping all lights off can make it difficult for them to find their way and increase their anxiety.
