Full Exam Paper & Marking Scheme
If a pt is getting chemo, what type of anemia does pt have? - secondary aplastic
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
beta thalassemia major causes skeletal deformities because of what - Erythropoeitin (EPO) and
bone 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 perfusion, tissues need more O2 so hbg dissociates to give up O2 to tissues
Pulmonary embolism causes a high V/Q mismatch and no perfusion. this is also called what? -
dead space
collapsed alveoli on V/Q gradient causes what? - right to left shunt and no gas exchange.
in the oxy-hemoglobin dissociation gradient, if the curve shifts to the RIGHT, it means what? -
hemoglobin gives up oxygen to give to tissues
which airway has the most resistance? - airway with the smallest diameter
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.
