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
Headaches and blurred vision are not specific to stage I Lyme disease. These symptoms can occur in many other conditions and are not the primary indicators of early Lyme disease.
Choice B rationale
Tremors and weakness are not typical early signs of Lyme disease. These symptoms are more associated with neurological involvement, which occurs in later stages of the disease.
Choice C rationale
Rash symptoms, specifically erythema migrans (a bull’s-eye rash), are the hallmark of stage I Lyme disease. This rash appears at the site of the tick bite and is a key diagnostic feature.
Choice D rationale
Painful joints are more commonly seen in later stages of Lyme disease when the infection has spread and caused more systemic involvement.
