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 C
Explanation
Choice A rationale
Pitting edema of the hands and fingers is not a typical finding in clients with systemic lupus erythematosus (SLE). Edema can occur in SLE, but it is more commonly associated with renal involvement and not specifically pitting edema of the hands and fingers.
Choice B rationale
Subcutaneous nodules on the ulnar side of the arm are more commonly associated with rheumatoid arthritis rather than SLE. SLE does not typically present with subcutaneous nodules.
Choice C rationale
A dry, red rash across the bridge of the nose and on the cheeks, known as a “butterfly rash,” is a classic sign of SLE. This rash is caused by inflammation of the small blood vessels in the skin and is often exacerbated by sun exposure.
Choice D rationale
A grey-colored, non-purpuric papular rash is not characteristic of SLE. The typical rash in SLE is the butterfly rash, which is dry, red, and raised.
Correct Answer is ["B","D","F"]
Explanation
Choice A rationale
Avoiding the use of insect repellent on the skin and clothing is not recommended. Insect repellents containing DEET are effective in preventing tick bites, which can transmit Lyme disease. The toxicity of DEET is minimal when used as directed.
Choice B rationale
Avoiding heavily wooded areas and areas with thick underbrush is recommended to reduce the risk of tick exposure. Ticks that carry Lyme disease are commonly found in these environments.
Choice C rationale
Wearing dark clothing is not recommended as it makes it harder to spot ticks. Light-colored clothing is preferable as it allows for easier detection of ticks.
Choice D rationale
Wearing long-sleeved tops and long pants with closed shoes is recommended to minimize skin exposure and reduce the risk of tick bites.
Choice E rationale
Reporting to the primary health care provider immediately for a blood test if a tick is found is not necessary. The presence of a tick does not immediately indicate Lyme disease. Instead, the tick should be removed promptly, and the area should be monitored for signs of infection.
Choice F rationale
Bathing after being in an infested area and inspecting the body carefully for ticks is recommended. This helps in early detection and removal of ticks, reducing the risk of Lyme disease.
