Which statement accurately defines psoriasis?
Psoriasis is an autoimmune disease that primarily affects the respiratory system.
Psoriasis is a bacterial skin infection caused by Streptococcus bacteria.
Psoriasis is a chronic inflammatory skin condition characterized by red, scaly patches.
Psoriasis is a type of skin cancer that arises from melanocytes.
The Correct Answer is C
Explanation: Psoriasis is a chronic skin disorder that results from an overactive immune response, leading to the rapid growth of skin cells. This causes red, raised, and scaly patches to form on the skin, which can be itchy and painful.
Incorrect choices: a. Psoriasis is not primarily an autoimmune disease affecting the respiratory system. It is primarily a skin condition, although it may be associated with certain autoimmune factors.
b. Psoriasis is not caused by a bacterial infection. It is a non-infectious skin disorder with an underlying immune-mediated mechanism.
d. Psoriasis is not a type of skin cancer. It is a benign skin condition that does not involve the malignant transformation of melanocytes.

Correct Answer is C
Explanation
Explanation: The typical clinical manifestations of psoriasis include red, raised, and scaly patches on the skin. These patches are often itchy and may be associated with discomfort.
Incorrect choices: a. Purulent discharge is not a characteristic feature of psoriasis. Psoriasis lesions typically do not contain pus.
b. Psoriasis lesions are not smooth and painless. They are raised and may be painful or itchy.
d. Ulcerated and bleeding skin sores are not typical of psoriasis. Psoriasis lesions are characterized by dry, scaly plaques rather than open sores.
Correct Answer is C
Explanation
Explanation: Genetic predisposition in psoriasis contributes to the development of the condition by causing abnormal functioning of the immune system. Certain genes involved in the immune response are associated with psoriasis, leading to an overactive immune system that triggers inflammation and skin cell overproduction.
Incorrect choices: a. Genetic factors increase skin sensitivity to environmental irritants: While some environmental triggers can worsen psoriasis symptoms, genetic predisposition primarily influences the immune system's response, not skin sensitivity to irritants.
b. Genetic factors cause an allergic reaction to certain foods: Psoriasis is not primarily an allergic reaction, and genetic factors do not cause allergic reactions to specific foods in this context.
d. Genetic factors impair the skin's barrier function: Psoriasis is not caused by a skin barrier dysfunction. The condition is characterized by immune system dysregulation and the subsequent inflammation and rapid skin cell turnover.
