NURS 5461 EXAM 1 with answers
|\ |\ |\ |\ |\
Microcytic anemia - CORRECT ANSWERS ✔✔iron deficiency,
|\ |\ |\ |\ |\ |\ |\
usually due to malabsorption / occult blood loss, or lead
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
poisoning. MCV <80 |\ |\
Normocytic anemia - CORRECT ANSWERS ✔✔due to hemorrhage
|\ |\ |\ |\ |\ |\ |\ |\
or chronic disease. Aplastic anemia. MVC 80-92
|\ |\ |\ |\ |\ |\
macrocytic anemia - CORRECT ANSWERS ✔✔due to folate or
|\ |\ |\ |\ |\ |\ |\ |\ |\
vitamin B12(cobalamin) deficiency (megaloblastic anemia) /
|\ |\ |\ |\ |\ |\
pernicious anemia. /liver diseases
|\ |\ |\
serum ferritin - CORRECT ANSWERS ✔✔Tests for iron stores. As
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
serum ferritin falls, TIBC rises, and serum iron levels will
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
eventually fall. |\
Anemia of chronic disease - CORRECT ANSWERS ✔✔NORMOcytic
|\ |\ |\ |\ |\ |\ |\ |\
anemia with ↓ serum iron, ↓ TIBC, and normal iron stores. Treat
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
with epoetin and give an iron supplement
|\ |\ |\ |\ |\ |\
Schistocytes - CORRECT ANSWERS ✔✔Associated with hemolytic
|\ |\ |\ |\ |\ |\ |\
uremia syndrome |\
,pernicious anemia - CORRECT ANSWERS ✔✔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.
|\ |\ |\ |\ |\
Increased homocysteine & methylmalonic acid level indicates ? -
|\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔B12 deficiency
|\ |\ |\
increased homocysteine levels - CORRECT ANSWERS ✔✔Folate
|\ |\ |\ |\ |\ |\ |\
deficiency
Sperocytes - CORRECT ANSWERS ✔✔Appear as spheres, lack
|\ |\ |\ |\ |\ |\ |\ |\
central pallor, smaller diameter, indicate immune-mediated
|\ |\ |\ |\ |\ |\
process - can be seen after blood transfusion
|\ |\ |\ |\ |\ |\ |\
aplastic anemia - CORRECT ANSWERS ✔✔a normocytic anemia
|\ |\ |\ |\ |\ |\ |\ |\
characterized by the failure of bone marrow to produce red blood
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
cells
Low ferritin - CORRECT ANSWERS ✔✔iron deficiency anemia
|\ |\ |\ |\ |\ |\ |\
Transferrin - CORRECT ANSWERS ✔✔transports iron
|\ |\ |\ |\ |\
, TIBC (total iron binding capacity) - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\
✔✔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
|\ |\ |\ |\ |\ |\ |\
MCHC (mean corpuscular hemoglobin concentration) - CORRECT
|\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔32 - 36 g/dL |\ |\ |\ |\
Concentration of hemoglobin per RBC |\ |\ |\ |\
Alzheimer's disease - CORRECT ANSWERS ✔✔Gradual onset with
|\ |\ |\ |\ |\ |\ |\ |\
early memory impairment. Most common form of dementia.
|\ |\ |\ |\ |\ |\ |\ |\
Cholinesterase inhibitors for early treatment. |\ |\ |\ |\
Lewy body dementia - CORRECT ANSWERS ✔✔usually a rapidly
|\ |\ |\ |\ |\ |\ |\ |\ |\
progressive form of dementia seen with Parkinson syndrome. -
|\ |\ |\ |\ |\ |\ |\ |\ |\
VISUAL HALLUCINATION ARE SEEN. |\ |\ |\
frontal lobe dementia - CORRECT ANSWERS ✔✔Seen before age
|\ |\ |\ |\ |\ |\ |\ |\ |\
60 w personality impairments. PDG-PET Scan testing. - decreased
|\ |\ |\ |\ |\ |\ |\ |\ |\
glucose uptake by the brain in frontal and temporal lobe
|\ |\ |\ |\ |\ |\ |\ |\ |\
PDG-PET SCAN - CORRECT ANSWERS ✔✔Measure brain
|\ |\ |\ |\ |\ |\ |\
metabolism of glucose. decreaesd uptake by temporal and parital
|\ |\ |\ |\ |\ |\ |\ |\ |\
lobe in Alzheimer's
|\ |\
