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.

Correct Answer is ["A","B","C","D"]

Explanation

Choice A rationale

A nagging cough is one of the seven warning signs of cancer. Persistent coughing or hoarseness can indicate lung cancer or other cancers affecting the respiratory system. It is important to investigate any chronic cough that does not resolve with standard treatment.

Choice B rationale

A non-healing sore is another warning sign of cancer. Sores that do not heal, especially in the mouth or on the skin, can be indicative of skin cancer or oral cancer. These sores may bleed, ooze, or become crusty and should be evaluated by a healthcare provider.

Choice C rationale

A change in moles is a significant warning sign of skin cancer, particularly melanoma. Changes in size, shape, color, or texture of a mole, or the appearance of new moles, should be assessed by a healthcare provider. Early detection of skin changes can lead to prompt treatment and better outcomes.

Choice D rationale

A change in bowel pattern is a warning sign of colorectal cancer. Symptoms such as persistent diarrhea, constipation, or changes in stool consistency or color can indicate an underlying malignancy in the digestive tract. It is important to seek medical evaluation for any unexplained changes in bowel habits.

Choice E rationale

Bloating is not typically included in the seven warning signs of cancer. While bloating can be a symptom of various conditions, including ovarian cancer, it is not one of the primary warning signs used to identify cancer. The focus should be on the more specific signs listed above.

Correct Answer is B

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.
