CMN 572 Exam 2 – Questions With Appropriate
Solutions
Anemia Correct Answer - 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?
Correct Answer - Iron deficiency anemia
Low MCH means Correct Answer - Hypochromic --> Low color
Low iron ____(high or low?) TIBC Correct Answer - high TIBC
First line defense Correct Answer - Neutrophils (50-70%)
Second line defense Correct Answer - Monocytes
Shift to left Correct Answer - Increase in bands --> acute
infection, laukemia, pernicious anemia
Shift to right Correct Answer - Increase in mature neutrophils
--> liver disease
Low ferritin Correct Answer - Iron deficiency anemia
Anisocytosis Correct Answer - presence of red blood cells of
unequal size
Peripheral smear Correct Answer - Uses sample of blood and
view under microscope to reveal RBC size, color, shape suggesting
type of anemia
,Poikilocytosis Correct Answer - Increase in abnormal RBCs of
any shape that makes up 10% or more of total population
Mentees index Correct Answer - MCV divided by RBC count;
helpful in differentiating IDA from beta thalassemia (<13 and RBC #
is not decreased)
Lifespan of RBCs Correct Answer - 120 days
Ferritin Correct Answer - Protein which stores iron reserves;
LOWERS BEFORE CHANGE SEEN IN HGB/HCT IN ANEMIA
1st sign of IDA; HIGH = liver damage / cancer
Pancytopenia Correct Answer - Depression of all 3 elements
1. RBC
2. WBC
3. Platelets
Shift to the left Correct Answer - Shift to left: increase in bands;
acute infection / leukemia / pernicious anemia
Shift to the right Correct Answer - Shift to right: increase in
mature neutrophils; seen in diseases of liver
Neutrophils Correct Answer - 1st line defense; Protect body
from infections by killing bacteria, fungi, foreign debris
Monocytes Correct Answer - 2nd line defense; Defend against
infection by cleaning up damaged cells
Basophils Correct Answer - Prevents blood clotting during
healing
, Baby neutrophils Correct Answer - Bands
Mounting the body in preparation to fight infection
MCH lab range Correct Answer - 27-31
MCH tells us Correct Answer - The color of the RBC
MCV lab range Correct Answer - 80-100
MCV tells us Correct Answer - The size of the RBC
Anytime the Poly's and lymphs are close in #, think________
Bacterial or Viral? Correct Answer - Viral
Anytime the Poly's and lymphs are far in #, think______
Bacterial or Viral? Correct Answer - Bacterial
Monocytes dont respond for how long? Correct Answer - 24
hours
If monocytes are elevated, how long has the pt been sick? Correct
Answer - > 24 hours
A pt has microcytic and hypochromic, what should be included in
your differential? Correct Answer - Thalassemia
Iron deficiency anemia
Thalassemia Correct Answer - Microcytic + Hypochromic
RDW = normal
Serum iron = normal
AVOID excessive iron
Do NOT replace iron
