Correct Answer is C

Explanation

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.

A. "I will moisturize my skin regularly to prevent dryness and scaling." B. "I will avoid using fragranced soaps and lotions on my skin." C. "I will apply sunscreen before going outside to protect my skin from UV rays." D. "I will take long, hot baths to soften the psoriatic plaques for easier removal."

Correct Answer is D

Explanation

Explanation: Taking long, hot baths can actually worsen psoriasis by drying out the skin and triggering flare-ups. Instead, patients with psoriasis should take short, lukewarm baths or showers to avoid exacerbating the condition.

Incorrect choices: a. Moisturizing the skin regularly is an essential part of psoriasis management to prevent dryness and scaling.

b. Avoiding fragranced soaps and lotions can help minimize skin irritation and sensitivity, which is beneficial for patients with psoriasis.

c. Applying sunscreen before going outside is important, as exposure to UV rays can trigger or worsen psoriasis. Sun protection helps prevent further skin damage.
