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?
Connective tissue.
Peripheral vascular system.
Lymphatic system.
Skeletal tissue.
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.

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.
