To diagnose someone with HIV, what do they look for in the blood?
You have a patient who has been injured by a rusty nail. As a precaution, you vaccinate her against tetanus.
In response to the vaccine, how does her body produce antibodies against C. tetani and prevent future illness due to tetanus?
A)B cells that produce an appropriate antibody undergo genomic rearrangement in order to produce other cells that secrete the same antibody.
B)Every cell in her immune system produces antibodies against C. tetani.
C)B cells with an appropriate antibody are stimulated to divide, producing plasma cells that make antibodies to C. tetani, and memory cells that "remember" C. tetani.
D)Every B cell in her body produces antibodies against C. tetani.
When a nurse takes your blood, why must the
collection tube be heparinized?
A) To prevent the blood from
agglutinating.
B) To keep the blood fresh so the
components don't break down before
the diagnostic tests can be run.
C) To prevent the blood from clotting after
collection.
D) To prepare the blood for a specific
diagnostic test that is going to be
performed.

These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following: A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other. B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same. C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement.
