The nurse is teaching a patient about psoriasis. Which statement by the patient indicates a need for further education?
"Psoriasis is a chronic skin condition that causes red, scaly patches on the skin."
"Psoriasis is an autoimmune disease that occurs when the body attacks healthy skin cells."
"Psoriasis is contagious and can be spread through direct contact with affected individuals."
"Treatment for psoriasis aims to reduce inflammation and slow down the rapid skin cell growth."
The Correct Answer is C
Explanation: Psoriasis is not contagious and cannot be spread through direct contact with affected individuals. It is an autoimmune disease where the immune system mistakenly attacks healthy skin cells, leading to the characteristic red, scaly patches on the skin.
Incorrect choices: a. This statement is correct. Psoriasis is a chronic skin condition that causes red, scaly patches on the skin.
b. This statement is correct. Psoriasis is indeed an autoimmune disease where the body's immune system attacks healthy skin cells.
d. This statement is correct. Treatment for psoriasis aims to reduce inflammation and slow down the rapid skin cell growth to manage the symptoms of the condition.

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.
Correct Answer is B
Explanation
Explanation: Psoriasis is characterized by the presence of itchy, raised, red patches on the skin with silvery scales. These patches are known as plaques and are a hallmark feature of psoriasis.
Incorrect choices: a. Painful, deep ulcers on the skin: This description does not align with psoriasis. Psoriasis plaques are not typically painful or ulcerated.
c. Small, fluid-filled blisters on the palms and soles: This description is more characteristic of a condition called palmoplantar pustulosis, not psoriasis.
d. Thickened, hardened skin with deep cracks: This description is more typical of a condition called lichenified eczema or chronic contact dermatitis, not psoriasis.
