what is a classic sign of all anemias? - ✔✔reduced oxygen carrying capacity
Ferritin levels in both ACD and IDA - ✔✔ACD has high ferritin and IDA has low
what are oral symptoms of IDA? - ✔✔tongue atrophy and glossitis
Is IDA micro or macro cytic? - ✔✔microcytic
is b12 and folate micro or macro cyctic? - ✔✔macrocytic
common theme between IDa, b12, and folate - ✔✔reticulopenia
what cells does b12 attack? - ✔✔gastric cells
if a baby is born with spina bifida, what means that the mother has what type of anemia? - ✔✔folate
deficiency anemia
what late symptom can b12 cause? - ✔✔neurological issues
acute blood loss anemia causes hemodilution because of what? - ✔✔fluid moving from the intracellular
space into intravascular space
what crisis does sickle cell disease cause? - ✔✔vaco-occlusive
, T/F: infants with HbF show signs of sickle cell before 6 months? - ✔✔false

marrow expansion
In blood smear, hemolytic anemia shows what type of cells? - ✔✔shistocytes
in the oxyhemoglobin dissociation curve, a shift to the RIGHT means what? - ✔✔decreased affinity, low

On spirogram, obstructive curve is: - ✔✔Prolonged expiration. curve is lower to the 1s
Define DLCO - ✔✔Diffusion of lung for carbon monoxide
How is DLCO used and measured? - ✔✔pt inhales small amount of CO and tracer, they hold breath for
10s and then exhale. exhale CO2 is meaured.
LOW DLCO is associated with what diease? - ✔✔Alveoliar capillary membrane disease/ restrictive lung
