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 D
Explanation
This is because a fall risk wristband alerts the staff and other caregivers that the client is at risk of falling and needs extra precautions and supervision. A walker, a cane, or a chair on either side of the bed are not priority interventions for a fall risk client, as they do not address the root cause of the problem or prevent potential falls.
Choice A is wrong because a walker may not be appropriate for the client’s condition or mobility level, and it may pose a tripping hazard if not used correctly.
Choice B is wrong because placing a chair on either side of the bed may limit the client’s access to the bed or the bathroom, and it may also create clutter and obstruction in the room.
Choice C is wrong because a cane may not provide enough stability or support for the client, and it may also be difficult to use in narrow spaces or on slippery surfaces.
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.
