The nurse is caring for a patient with psoriasis who is prescribed a topical retinoid. Which instruction should the nurse provide to the patient regarding the use of topical retinoids?
"Apply the topical retinoid directly to wet skin after bathing."
"Use the topical retinoid only on affected areas of psoriasis plaques."
"You may experience immediate relief of itching and redness after applying the retinoid."
"Avoid sun exposure and use sunscreen when using topical retinoids."
The Correct Answer is D
Explanation: Topical retinoids can increase the skin's sensitivity to sunlight and may cause sunburn. Patients should avoid excessive sun exposure and use sunscreen to protect their skin when using topical retinoids.
Incorrect choices: a. Topical retinoids should be applied to dry skin, not wet skin, to ensure proper absorption and effectiveness.
b. Topical retinoids are typically applied to the entire affected area, not just individual psoriasis plaques. They work best when applied consistently to the entire affected area.
c. Topical retinoids may take several weeks to show significant improvement in psoriasis symptoms, and immediate relief is not typical.

Correct Answer is B
Explanation
Explanation: Psoriasis is an autoimmune skin disorder where the immune system mistakenly attacks healthy skin cells, leading to the rapid buildup of skin cells and the formation of red, scaly patches on the skin's surface.
Incorrect choices: a. A contagious bacterial skin infection - Psoriasis is not caused by bacteria, and it is not contagious.
c. A fungal infection causing itching and rash - Psoriasis is not caused by a fungus; it is an autoimmune condition.
d. A viral skin condition resulting in fluid-filled blisters - Psoriasis does not result in fluid-filled blisters; it presents as red, scaly patches instead.
Correct Answer is C
Explanation
Explanation: The primary etiological factor in psoriasis is a genetic predisposition. Psoriasis has a strong hereditary component, and individuals with a family history of the condition are at a higher risk of developing it. While environmental triggers can exacerbate psoriasis symptoms, the condition itself is primarily influenced by genetic factors.
Incorrect choices: a. Bacterial infection: Psoriasis is not caused by a bacterial infection. It is an autoimmune condition characterized by an overactive immune response, leading to inflammation and skin cell overproduction.
b. Fungal overgrowth: Fungal overgrowth is not a cause of psoriasis. Psoriasis is not related to fungal infections and has a different underlying mechanism.
d. Allergic reaction: While certain allergens may exacerbate psoriasis symptoms in some individuals, an allergic reaction is not the primary cause of psoriasis. The condition's pathophysiology is rooted in immune system dysfunction rather than allergic responses.
