Histamine release

T-lymphocyte memory cells

Immunosuppression

Antigen/antibody interaction

Answer and Explanation

The Correct Answer is B

Histamine release: Histamine release is characteristic of Type I hypersensitivity reactions (immediate hypersensitivity) rather than Type IV.

T-lymphocyte memory cells: Type IV hypersensitivity is a delayed response mediated by T-lymphocytes, not antibodies.

Immunosuppression: Immunosuppression is not directly related to hypersensitivity reactions.

Antigen/antibody interaction: This is characteristic of Types I, II, and III hypersensitivity reactions, not Type IV.

Correct Answer is B

Explanation

A. "You need to stay on antibiotics for the rest of your life."Lifelong antibiotic therapy is not standard post-transplant care, though immunosuppressants are required.
B. "You should avoid people that are sick to decrease the risk of you getting an infection." Immunosuppressive medications used post-transplant increase the risk of infections.
C. "You need to stay on antihistamines the rest of your life."Antihistamines are not a routine part of post-transplant care.
D. "You can drink as much alcohol as you want."Alcohol should be strictly avoided to protect the transplanted liver.

Correct Answer is B

Explanation

A. A CD4 count 300/μL: Although this may indicate immunosuppression, it is not consistent with AIDS, which requires a CD4 count below 200/μL.
B. A CD4 count 100/μL: This count is indicative of advanced AIDS, where patients are highly susceptible to opportunistic infections.
C. A CD4 count of 800/μL: This is within the normal range for a healthy individual.
D. A CD4 count of 600/μL: This is still within the normal range and does not indicate AIDS.
