CMN 572 - Exam 2
Anemia
dA broac high yield diagnoses usually suspected by physical findings and the lab
parameters of a low hct/hgb
A patient has pica, what type of anemia should be a concern?
Iron deficiency anemia
Low MCH means
Hypochromic --> Low color
Low iron ____(high or low?) TIBC
high TIBC
First line defense
Neutrophils (50-70%)
Second line defense
Monocytes
Shift to left
Increase in bands --> acute infection, laukemia, pernicious anemia
Shift to right
Increase in mature neutrophils --> liver disease
Low ferritin
,Iron deficiency anemia
Anisocytosis
presence of red blood cells of unequal size
Peripheral smear
Uses sample of blood and view under microscope to reveal RBC size, color,
shape suggesting type of anemia
Poikilocytosis
Increase in abnormal RBCs of any shape that makes up 10% or more of total
population
Mentees index
MCV divided by RBC count; helpful in differentiating IDA from beta thalassemia
(<13 and RBC # is not decreased)
Lifespan of RBCs
120 days
Ferritin
Protein which stores iron reserves; LOWERS BEFORE CHANGE SEEN IN
HGB/HCT IN ANEMIA
1st sign of IDA; HIGH = liver damage / cancer
Pancytopenia
Depression of all 3 elements
1. RBC
2. WBC
, 3. Platelets
Shift to the left
Shift to left: increase in bands; acute infection / leukemia / pernicious anemia
Shift to the right
Shift to right: increase in mature neutrophils; seen in diseases of liver
Neutrophils
1st line defense; Protect body from infections by killing bacteria, fungi, foreign
debris
Monocytes
2nd line defense; Defend against infection by cleaning up damaged cells
Basophils
Prevents blood clotting during healing
Baby neutrophils
Bands
Mounting the body in preparation to fight infection
MCH lab range
27-31
MCH tells us
The color of the RBC
