Question 1:

Which of the following is an example of an immune system disorder?

Explanation: Asthma is an example of an immune system disorder. Asthma is a chronic inflammatory condition that affects the airways, leading to wheezing, shortness of breath, and coughing. Diabetes mellitus, hypertension, and osteoarthritis are not primarily immune system disorders. Therefore, option D is correct.

Question 2:

Which of the following is a treatment option for immune system disorders?

Explanation: Immunosuppressive drugs are a treatment option for immune system disorders. These drugs help suppress the overactive immune response that occurs in immune system disorders, such as autoimmune diseases. Antibiotics are used to treat bacterial infections, vaccines are used to prevent infectious diseases, and physical therapy is a rehabilitation treatment for certain musculoskeletal conditions. Therefore, option C is correct.

Question 3:

Which of the following is a potential complication of immunosuppressive therapy?

Explanation: Infection is a potential complication of immunosuppressive therapy. Immunosuppressive drugs weaken the immune system's ability to fight off infections, making individuals more susceptible to bacterial, viral, and fungal infections. Allergic reactions, muscle strains, and vision problems are not directly related to immunosuppressive therapy. Therefore, option B is correct.

Question 4:

Which of the following is an example of an immune system disorder characterized by excessive immune activity?

Explanation: Rheumatoid arthritis is an example of an immune system disorder characterized by excessive immune activity. Rheumatoid arthritis is an autoimmune disease in which the immune system mistakenly attacks the body's own joint tissues, leading to inflammation, pain, and joint damage. Lupus, primary immunodeficiency, and multiple sclerosis involve immune system abnormalities but are not primarily characterized by excessive immune activity. Therefore, option A is correct.

Question 5:

What is the goal of immunotherapy?

Explanation: The goal of immunotherapy is to boost the immune response. Immunotherapy involves using treatments that enhance the body's natural defense mechanisms to fight diseases such as cancer and autoimmune disorders. Suppressing the immune response is the goal in certain immune system disorders, but not in the context of immunotherapy. Eliminating the pathogen causing the disease is more relevant to antimicrobial treatments. Modifying the genetic makeup of cells is not a direct goal of immunotherapy. Therefore, option A is correct.
