NURS 5461 EXAM 1 The University of Texas at Arlington | UPDATED
Questions with 100% Verified Answers
Question:
Microcytic anemia
Answer:
iron deficiency, usually due to malabsorption / occult blood
loss, or lead poisoning. MCV <80
Question:
Normocytic anemia
Answer:
due to hemorrhage or chronic disease. Aplastic anemia. MVC
80-92
Question:
macrocytic anemia
Answer:
due to folate or vitamin B12(cobalamin) deficiency
(megaloblastic anemia) / pernicious anemia. /liver diseases
Question:
serum ferritin
Answer:
Tests for iron stores. As serum ferritin falls, TIBC rises, and
serum iron levels will eventually fall.
Question:
Anemia of chronic disease
Answer:
NORMOcytic anemia with · serum iron, · TIBC, and normal iron
stores. Treat with epoetin and give an iron supplement
,Question:
Schistocytes
Answer:
Associated with hemolytic uremia syndrome
Question:
pernicious anemia
Answer:
Macrocytic anemia caused by vitamin B12 deficiency. B12 is
essential to maturation of erythrocytes - low levels will cause
the RBC to expand. PPIs and histamine2 blockers can cause
this.
Question:
Increased homocysteine & methylmalonic acid level indicates
?
Answer:
B12 deficiency
Question:
increased homocysteine levels
Answer:
Folate deficiency
Question:
Sperocytes
Answer:
Appear as spheres, lack central pallor, smaller diameter,
indicate immune-mediated process - can be seen after blood
transfusion
Question:
aplastic anemia
, Answer:
a normocytic anemia characterized by the failure of bone
marrow to produce red blood cells
Question:
Low ferritin
Answer:
iron deficiency anemia
Question:
Transferrin
Answer:
transports iron
Question:
TIBC (total iron binding capacity)
Answer:
Available transferrin that is left unbound (Represents the
"empty seats on a train"). When iron is low, TIBC will be
high. When iron is high, TIBC will be low
Question:
MCHC (mean corpuscular hemoglobin concentration)
Answer:
32 - 36 g/dL Concentration of hemoglobin per RBC
Question:
Alzheimer's disease
Answer:
Gradual onset with early memory impairment. Most common
form of dementia. Cholinesterase inhibitors for early
treatment.
