Multiple organ dysfunction syndrome (MODS)
Give this one a try later!
Progressive impairment of two or more organ systems resulting from an
uncontrolled inflammatory response to a severe illness or injury.
True or false: folate deficiency is the most common cause of macrocytic anemia.
,Give this one a try later!
True; the body only stores a 4-5 month supply of folate.
How does viral meningitis develop?
Give this one a try later!
A virus penetrates into the CNS via blood or travels along the nerve root.
Develops over several days and may not necessarily need hospitalization.
State lab findings seen in B12 deficiency
Give this one a try later!
MCV > 100 fl., low reticulocyte count, low B12 (< 200), possible (+) intrinsic
factor antibody (pernicious anemia), elevated methylmalonic acid (MMA),
and normal homocysteine.
Macrocytic anemia
Give this one a try later!
An underproduction anemia that arises commonly from abnormalities that
hinder the maturation of erythroid precursors in the bone marrow. Typically
B12 or folate deficiency. MCV > 100 fl.
, Subarachnoid hemorrhage (SAH)
Give this one a try later!
Bleeding into the subarachnoid space surrounding the brain tissue. Causes:
trauma, aneurysmal, dissection, neoplastic.
Cerebellar herniation
Give this one a try later!
Dislocation of the cerebellum downward through the cerebellar tonsils,
resulting in sudden respiratory arrest.
State lab findings seen in Sickle cell anemia
Give this one a try later!
Normal iron studies, elevated reticulocyte count, elevated MCV, elevated
unconjugated bili and LDH, and low haptoglobin.
Central herniation
Give this one a try later!
Frontal or parietal tissue exerts a downward force and compresses the
midbrain and may stop blood flow to the brain, resulting in brain death. S/s:
