A nurse is caring for a client who has a new diagnosis of systemic lupus erythematosus (SLE) and asks where this disease originates within the body. The nurse should tell the client that SLE originates in which of the following locations in the body?

A.

Connective tissue.

B.

Peripheral vascular system.

C.

Lymphatic system.

D.

Skeletal tissue.

Answer and Explanation

The Correct Answer is A

Choice A rationale

 

Systemic lupus erythematosus (SLE) is an autoimmune disease that primarily affects connective tissue. The immune system mistakenly attacks healthy tissue, leading to inflammation and damage.

 

Choice B rationale

 

SLE does not originate in the peripheral vascular system, although it can cause complications in blood vessels.

 

Choice C rationale

 

While the lymphatic system is involved in immune responses, SLE primarily targets connective tissue.

 

Choice D rationale

 

SLE does not originate in skeletal tissue, though it can cause joint pain and arthritis.

Correct Answer is A

Explanation

Choice A rationale

Cataracts cause the lens of the eye to become cloudy, leading to a decreased ability to perceive colors. This is due to the scattering of light as it passes through the cloudy lens, which reduces the clarity and vibrancy of colors.

Choice B rationale

Loss of peripheral vision is more commonly associated with glaucoma, a condition where increased intraocular pressure damages the optic nerve.

Choice C rationale

Seeing bright flashes of light and floaters is typically a symptom of retinal detachment, a serious condition where the retina pulls away from its normal position.

Choice D rationale

Loss of central vision is often linked to macular degeneration, a condition that affects the central part of the retina responsible for sharp, detailed vision.

Correct Answer is B

Explanation

Choice A rationale

Electrical cords placed along the walls are generally not a safety risk as long as they are secured and not in the walking path. This placement can actually reduce tripping hazards.

Choice B rationale

Scatter rugs are a significant safety risk for older adults with decreased vision. They can easily cause tripping and falls, which can lead to serious injuries.

Choice C rationale

Handrails in the bathroom are a safety feature that helps prevent falls and provides support for individuals with decreased vision or mobility issues.

Choice D rationale

Using a microwave for cooking is generally safe for older adults with decreased vision as it reduces the risk of burns and accidents associated with stovetop cooking.
