Systemic lupus erythematosus is an example of which type of hypersensitivity reaction?

A. "The antibiotic I have been taking doesn't work as well as it used to."
This statement shows awareness of decreased effectiveness, which can occur due to drug resistance. Bacteria can become resistant to antibiotics, leading to reduced efficacy of the medication over time.

B. "The bacteria in my body have become resilient."
This statement correctly attributes resistance to the bacteria. Resilience in this context means that bacteria have developed mechanisms to survive the effects of antibiotics, making the treatment less effective.

C. "Over time, an organism that had once been highly sensitive to an antibiotic may become less susceptible, or it may lose drug sensitivity entirely."
This statement accurately describes the concept of drug resistance. Bacteria can lose sensitivity to antibiotics, rendering the drugs ineffective against them.

D. "My body has become resistant to the antibiotic."
This statement is incorrect. It's the bacteria that develop resistance, not the patient's body. Patients don't become resistant to antibiotics; instead, bacteria evolve and adapt, making the drugs less effective against them.

A. Cushing's Syndrome: This is a condition caused by prolonged exposure to high levels of cortisol, a hormone produced by the adrenal glands. It is not related to kidney transplant or immunosuppressive therapy.

B. Hypersensitivity Reaction Type I: Also known as an immediate hypersensitivity reaction or an allergy, this type of reaction involves the immune system's exaggerated response to an allergen. Symptoms can range from mild to severe and occur quickly after exposure to the allergen. While allergies can cause various symptoms, they do not specifically represent rejection of a transplanted organ.

C. Chronic Graft Versus Host Rejection: This term is commonly associated with bone marrow or stem cell transplants. It occurs when immune cells from the donated tissue recognize the recipient's body as foreign and attack various organs or tissues. This process typically happens over a more extended period and is not directly related to the scenario described.

D. Acute Host Versus Graft Rejection: This occurs when the recipient's immune system recognizes the transplanted organ as foreign and launches an immune response against it. It can happen shortly after transplantation if the recipient's immune system is not adequately suppressed. In this case, stopping immunosuppressive therapy can trigger acute rejection, leading to the failure of the transplanted organ.
