what is anemia? [ Ans: ] rbc deficiency
what are the causes of anemia? [ Ans: ] - blood loss or
hemorrhage (like in periods, GI bleeding)
© 2025 Assignment Expert
- accelerated hemolysis (like in sickle cell)
- decreased rbc production
what are the clinical manifestations of anemia? [ Ans: ] - pallor
Guru01 - Stuvia
- fatigue
- tachycardia
- tachypnea
- dizziness
- weakness
all of these are the bodys response to stress
the suffix "-cytic" when talking about the morphology of RBCs
refers to what? [ Ans: ] the size or volume of the circulating RBC
if an RBC is normocytic, that means what? [ Ans: ] it is of normal
size/volume
if an RBC is microcytic, that means what? [ Ans: ] abnormally
small in size/volume
if an RBC is macrocytic, that means what? [ Ans: ] abnormally
large in size/volume
the suffix "-chromic" when talking about the morphology of a RBC
refers to what? [ Ans: ] the color of the RBC based on Hgb
content

if a RBC is normochromic, what does it look like? [ Ans: ] normal
Hgb content, red
if a RBC is hypochromic, what does it look like? [ Ans: ] low Hgb
content, pale
can RBCs ever have too much hemoglobin? [ Ans: ] no, not a
problem
what is hemoglobin? [ Ans: ] the amount of available O2
carrying RBCs
what is hematocrit? [ Ans: ] percent of blood volume that is
RBCs
what is MCV? [ Ans: ] mean corpuscular volume - average
© 2025 Assignment Expert
volume and size of individual red blood cells
what is MCHC? [ Ans: ] mean corpuscular hemoglobin
concentration - average Hgb concentration relative to the size of
Guru01 - Stuvia
a RBC, average color of RBC
what is MCH? [ Ans: ] mean corpuscular hemoglobin - average
amount of hemoglobin per RBC, weigh of hemoglobin on RBC
if we have a low MCHC, what does that tell us about the
appearance of the RBC? [ Ans: ] hypochromic, low hgb
if we have a low MCH, what does that tell us about the
appearance of the RBC? [ Ans: ] hypochromic, low hgb
what does RDW measure? [ Ans: ] variation in size of RBCs
(difference between largest and smallest RBCs, we don't want it
high)
what is the reticulocyte count? [ Ans: ] measure of immature
RBCs, indicates red bone marrow function
what does an increased reticulocyte count indicate? [ Ans: ]
something is simulating RBC production like acute bleeding, giving
epogen)
what is TIBC? [ Ans: ] total iron binding capacity - measure of
how much iron is on the transferrin molecules in the blood
, 3
For Expert help and assignment solutions, +254707240657
what is transferrin? [ Ans: ] protein transporting iron from the GI
tract to various storage sites
what does it mean if there is a lot of iron on the transferrin, how
does this reflect in the TIBC? [ Ans: ] we have plenty of iron in
storage, low TIBC
what does it mean if there is not a lot of iron on the transferrin, how
does this reflect in the TIBC? [ Ans: ] not enough supply of iron,
high TIBC (high capacity to carry iron)
what is serum ferritin? [ Ans: ] stored form of iron, amount of iron
in storage (spleen, liver, bone marrow)
when will you see a low serum ferritin? [ Ans: ] when there is low
© 2025 Assignment Expert
iron stores
when will you see an increased serum ferritin? [ Ans: ] when we
have high iron stores
Guru01 - Stuvia
why is serum iron not an accurate measure of iron? [ Ans: ] not
as sensitive as ferritin or TIBC, iron is usually in the stored form and
measured as ferritin
what causes iron deficiency anemia? [ Ans: ] inadequate
supply of dietary iron or blood loss
what is the morphology of iron deficiency anemia? [ Ans: ]
microcytic, hypochromic
who is at risk for iron deficiency anemia? [ Ans: ] women of
child-bearing years (menses, pregnancy, lactation),
infants/children/adolescents in rapid growth phases, poor intake
what are the expected labs for iron deficiency anemia? what will
be low, and what will be high? [ Ans: ] - low H/H
- low MCH
- low MCV
- low MCHC (microcytic, hypochromic)
- low serum ferritin and serum iron
- high TIBC
, 4
For Expert help and assignment solutions, +254707240657
- high RDW
what is the pathophysiology of iron deficiency anemia? [ Ans: ]
- iron stores depleted
- decreased iron transported to bone marrow
- iron deficient erythropoiesisr
- microcytic and hypochromic RBCs produced
what is iron deficient erythropoiesis? [ Ans: ] insufficient hgb on
pale and small RBCS enter circulation due to demand but don't
carry oxygen like needed
what are the signs and symptoms of iron deficiency anemia? [
© 2025 Assignment Expert
Ans: ] - typical signs of anemia: fatigue, dizzy, weak,
tachycardia, tachypnea, pallor
- glossitis: sore/inflamed tongue
- koilonychia: brittle, spoon shaped nails
Guru01 - Stuvia
- pica: craving non food substances like ice or dirt
- headache
- poor appetite
how is iron deficiency anemia treated? [ Ans: ] increased oral
intake and supplementation
what are iron rich foods? [ Ans: ] shellfish, pork and chicken and
beef livers, beef, turkey, cooked beans, lentils, canned beans,
tofu, baked potato skins, black molasses, dark green leafy
vegetables, canned asparagus, pumpkin seeds, raisins
what enhances iron absorption? [ Ans: ] vitamin C
what inhibits iron absorption? [ Ans: ] dairy, antacids
when is the best time to take iron supplement? [ Ans: ] 1 hour
before or 2 hours after meals (empty stomach with water or fruit
juice)
what are the common GI side effects of iron supplementation? [
Ans: ] nausea, vomiting, constipation, dark stools
