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?

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.

Explanation: Psoriasis is characterized by red and raised skin patches covered with silver or white scales. These patches are often itchy and can be found on various parts of the body, such as the scalp, elbows, knees, and lower back.

Incorrect choices: a. Clear and smooth skin without any changes is not consistent with psoriasis, which is marked by visible skin changes like red, raised patches.

c. Skin rash with fluid-filled blisters may indicate conditions such as contact dermatitis or eczema but is not typical of psoriasis.

d. Purple or red lumps under the skin are more suggestive of other conditions, such as nodules or hematomas, rather than psoriasis.
