Question
The nurse is discussing the underlying mechanism of psoriasis with a client recently diagnosed with the condition. The nurse explains that psoriasis is primarily associated withA. overactivity of the immune system targeting healthy skin cells.B. deficiency of T lymphocytes leading to skin inflammation.C. impaired production of melanocytes causing skin discoloration.D. excessive sebum production resulting in follicular plugging.
Solution
Psoriasis is primarily associated with overactivity of the immune system targeting healthy skin cells.
Here's a step-by-step explanation:
-
Psoriasis is a chronic skin condition that speeds up the life cycle of skin cells. This causes cells to build up rapidly on the surface of the skin, forming scales and red patches that are sometimes painful.
-
This process is driven by the immune system. In people with psoriasis, T cells (a type of white blood cell that fights off viruses and bacteria) mistakenly attack healthy skin cells.
-
In response to this attack, the body starts to produce new skin cells more quickly than they can be shed. This leads to a buildup of skin cells on the surface of the skin, which is what causes the characteristic plaques of psoriasis.
-
So, the primary underlying mechanism of psoriasis is an overactive immune system that targets healthy skin cells. This is different from a deficiency of T lymphocytes, impaired production of melanocytes, or excessive sebum production, which are associated with other skin conditions.

The information in the passage suggests that which characteristic of atopic dermatitis is mediated by B-lymphocytes?A.Joint painB.Prevalence within familiesC.Involvement of both the epidermis and dermisD.Inflammation away from the site of allergen contact
Atopic dermatitis (AD) and contact dermatitis (CD) are two types of inflammatory skin diseases that differ in key characteristics. AD is a chronic condition that commonly affects the skin covering several joints, both exposed to environmental allergens as well as covered by clothing, whereas CD is usually confined to skin that comes into contact with allergens or irritants. AD typically involves the epidermal layer of the skin whereas CD may involve both the epidermis and dermis. Skin affected by AD oozes before becoming chronically dry and scaly; inflammation associated with CD typically resolves within days.Although no cures exist for either AD or CD, management of skin inflammation can be achieved through treatments that suppress inflammation. Multiple factors are thought to contribute to the origin of inflammatory skin diseases, including genetic, immune, and environmental causes. Inflammatory skin disease tends to run in families, a phenomenon that may be related to protein defects. For example, an inherited defect in a structural protein synthesized by keratin-producing epithelial cells is thought to be a key driver of AD.Some research suggests that inflammatory skin disease may be related to a hyperactive immune response. Normally, immune cells discriminate between harmful pathogens and harmless substances. If a harmless molecule that commonly touches the skin causes a response as though the molecule were harmful, further contact may produce an inflammatory response.The hypothesis that modern hygiene plays a role in the development of inflammatory skin disease has also been advanced. For example, frequent hand-washing with soap and water may remove skin oils, leaving the skin more sensitive to common irritants. Question 34Scientists have developed an experimental treatment for inflammatory skin diseases that modifies the activity of certain T-lymphocytes. One function of T-lymphocytes is to:A.present foreign antigen fragments on cell membranes.B.promote a distinct innate immune system response to a specific pathogen.C.secrete signaling molecules that activate other immune cells.D.engulf foreign substances and cellular debris.
