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.

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.
