Which of the following statements is true regarding the distribution of psoriasis lesions on the body?
Psoriasis lesions are evenly distributed across the body.
Psoriasis lesions are typically limited to the face and neck.
Psoriasis lesions are more commonly found on the left side of the body.
Psoriasis lesions are often symmetrical, affecting corresponding areas on both sides of the body.
The Correct Answer is D
Explanation: Psoriasis lesions commonly appear in a symmetrical pattern, affecting similar areas on both sides of the body. For example, if a plaque is present on the right elbow, there is a high likelihood of a corresponding plaque on the left elbow.
Incorrect choices: a. Psoriasis lesions are evenly distributed across the body: Psoriasis lesions are not evenly distributed and tend to cluster in certain areas, such as elbows, knees, scalp, and lower back.
b. Psoriasis lesions are typically limited to the face and neck: While psoriasis can occur on the face and neck, it is more commonly found on extensor surfaces (elbows and knees) and the scalp.
c. Psoriasis lesions are more commonly found on the left side of the body: There is no evidence to support a preference for the left side of the body in psoriasis distribution. The symmetrical pattern is a more characteristic feature.

Correct Answer is A
Explanation
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.
Correct Answer is A
Explanation
Explanation: Psoriasis has a strong genetic component, and individuals with a family history of the condition are more likely to develop it. Specific genetic factors are involved in the immune response and skin cell growth regulation, leading to psoriasis.
Incorrect choices: b. While exposure to certain chemicals and irritants can exacerbate psoriasis symptoms, they are not the primary factor contributing to its development.
c. Psoriasis is not caused by a bacterial infection. It is a non-infectious inflammatory skin disorder.
d. Sun exposure can affect psoriasis, but it is not the primary factor contributing to its development. In some cases, moderate sunlight exposure may even improve psoriasis symptoms.
