Question 1
Which of the following patients is most likely to benefit from transportation of thymic
tissue or major histocompatibility complex ( MHC) – compatible bone marrow?
A 12-year
old girl with a history of epilepsy and low IgG levels secondary to phenytoin use
A 7-year old boy whose blood work indicates decreased IgA and IgG with increased IgM
A 6-year-old boy whose pre-B cells are incapable of translation to normal B cells
A 9-year-old girl who has a diagnosis of IgA deficiency
Question 2
As part of his diagnostic workup, a 77 yo man nurse practitioner has ordered blood work
that includes ferritin levels. The man is very interested in the details of his health care is
unfamiliar with ferritin and it’s role. Which of the following explanations by the nurse
practitioner is most accurate?
“Ferritin is the activated and usable form of iron that your red blood cells can use to
transport oxygen.”
“Ferritin is a stored form of iron that indirectly shows me whether you would benefit
from iron pills.”
“Ferritin is a protein-iron complex that allows your red blood cells to make use of the
iron that you consume in your diet.”
“Ferritin is the form of iron that is transported in your blood plasma to the red blood
cells that need it.”
Question 3
, The blood work of a 44 yo male with a diagnosis of liver disease secondary to alcohol
abuse indicates low levels of albumin. Which of the following phenomena would a
clinician be most justified in anticipating?
Impaired immune function
Acid–base imbalances
Impaired thermoregulation
Fluid imbalances
Question 4
A 14 yo boy has been diagnosed with infectious Mono.Which of the following
pathophysiological phenomena is most responsible for his symptoms?
The Epstein-Barr virus (EBV) is lysing many of the boy’s neutrophils.
Viruses are killing some of his B cells and becoming incorporated into the genome of
others.
The EBV inhibits the maturation of white cells within his peripheral lymph nodes.
The virus responsible for mononucleosis inhibits the maturation of myeloblasts into
promyelocytes.
Question 5
Which of the following phenome would be least likely to result in activation of the
complement system?
Recognition of an antibody bound to the surface of a microbe
Increase in tissue blood flow and capillary permeability, so fluids/proteins can leak into
the area
Activation of toll-like receptors (TLRs) on complement proteins
Direct recognition of microbial proteins
