Psoriasis is best described as:

Explanation: Immunosuppressive medications can weaken the immune system, making the patient more susceptible to infections. It is important for the patient to promptly report any signs of infection or illness to their healthcare provider for appropriate management.

Incorrect choices: b. The administration of immunosuppressive medications is often specific to each medication and should be taken as prescribed by the healthcare provider, with or without food, as indicated.

c. Immunosuppressive medications can increase the risk of infections, but they do not directly increase the risk of sunburn. Patients should, however, be cautious about sun exposure due to potential skin sensitivity.

d. Discontinuing immunosuppressive medications abruptly can be dangerous and should only be done under the guidance of a healthcare provider. Sudden discontinuation can lead to worsening of psoriasis and potential rebound effects.

Explanation: Psoriasis is an autoimmune disorder characterized by an overactive immune system. In psoriasis, the immune system mistakenly triggers inflammation, leading to the rapid growth of skin cells and the formation of plaques.

Incorrect choices: a. Immune system suppresses inflammation and skin cell proliferation: This statement is incorrect. In psoriasis, the immune system does not suppress inflammation but rather promotes it.

b. Immune system responds normally to environmental triggers: This statement is incorrect. In psoriasis, the immune system's response to triggers is abnormal, leading to the characteristic inflammation and skin cell overgrowth.

d. Immune system functions independently of psoriasis development: This statement is incorrect. The immune system plays a central role in psoriasis etiology. The abnormal immune response is the driving force behind the development and progression of psoriasis.
