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.

Correct Answer is ["B","C","D","F"]
Explanation
Choice A rationale
Increased awareness is not a manifestation of anaphylactic shock. Anaphylactic shock typically causes confusion or loss of consciousness due to decreased blood flow to the brain.
Choice B rationale
Chest pain can occur during anaphylactic shock due to the body’s severe allergic reaction and the strain it places on the cardiovascular system.
Choice C rationale
Dyspnea, or difficulty breathing, is a common manifestation of anaphylactic shock. The airways can become constricted, making it hard to breathe.
Choice D rationale
Angioedema, or swelling of the deeper layers of the skin, often occurs during anaphylactic shock. It can affect the face, throat, and other areas.
Choice E rationale
Hypertension, or high blood pressure, is not a typical manifestation of anaphylactic shock. Anaphylactic shock usually causes hypotension, or low blood pressure.
Choice F rationale
Urticaria, or hives, is a common skin reaction during anaphylactic shock. It presents as red, itchy welts on the skin.
Correct Answer is C
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.
