MGRADES EXAMS
NURS 5461 EXAM 1 UPDATED ACTUAL
Exam Questions and CORRECT Answers
Microcytic Anemia - CORRECT ANSWER - Iron deficiency, usually due to
malabsorption/occult blood loss, or lead poisoning. MCV <80
Normocytic Anemia - CORRECT ANSWER - Due to hemorrhage or chronic disease.
Aplastic anemia. MCV 80-92
Macrocytic Anemia - CORRECT ANSWER - Due to folate or vitamin B12 (cobalamin)
deficiency (megaloblastic anemia)/pernicious anemia/liver diseases
Serum Ferritin - CORRECT ANSWER - Tests for iron stores. As serum ferritin falls, TIBC
rises, and serum iron levels will eventually fall.
Anemia of Chronic Disease - CORRECT ANSWER - Normocytic anemia with ↓ serum iron,
↓ TIBC, and normal iron stores. Treat with epoetin and give an iron supplement
Schistocytes - CORRECT ANSWER - Associated with hemolytic uremia syndrome
Pernicious Anemia - CORRECT 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.
Increased Homocysteine & Methylmalonic Acid Level - CORRECT ANSWER - Indicates
B12 deficiency
Increased Homocysteine Levels - CORRECT ANSWER - Folate deficiency
, MGRADES EXAMS
Spherocytes - CORRECT ANSWER - Appear as spheres, lack central pallor, smaller
diameter, indicate immune-mediated process - can be seen after blood transfusion
Aplastic Anemia - CORRECT ANSWER - Failure of bone marrow to produce red blood cells
Low Ferritin - CORRECT ANSWER - Iron Deficiency Anemia
Transferrin - CORRECT ANSWER - Transports Iron
TIBC (Total Iron Binding Capacity) - CORRECT ANSWER - Available transferrin that is left
unbound. Reflects iron levels.
MCHC (Mean Corpuscular Hemoglobin Concentration) - CORRECT ANSWER -
Concentration of hemoglobin per RBC
Alzheimer's Disease - CORRECT ANSWER - Gradual onset with early memory impairment.
Most common form of dementia.
Lewy Body Dementia - CORRECT ANSWER - Rapidly progressive dementia seen with
Parkinson syndrome. Visual hallucinations present.
Frontal Lobe Dementia - CORRECT ANSWER - Personality impairments before age 60.
PDG-PET Scan testing.
PDG-PET Scan - CORRECT ANSWER - Measures brain glucose metabolism. Decreased
uptake in Alzheimer's.
SSRIs - CORRECT ANSWER - Fluoxetine, Paroxetine, Sertraline, Citalopram
