NURS 5461 EXAM 1 Questions And Correct
Answers (Verified Answers) 2026
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. MVC 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 indicates ? - CORRECT ANSWER -B12
deficiency
increased homocysteine levels - CORRECT ANSWER -Folate deficiency
, Sperocytes - CORRECT ANSWER -Appear as spheres, lack central pallor, smaller diameter,
indicate immune-mediated process - can be seen after blood transfusion
aplastic anemia - CORRECT ANSWER -a normocytic anemia characterized by the 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 (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 ANSWER -32 - 36 g/dL
Concentration of hemoglobin per RBC
Alzheimer's disease - CORRECT ANSWER -Gradual onset with early memory impairment.
Most common form of dementia. Cholinesterase inhibitors for early treatment.
Lewy body dementia - CORRECT ANSWER -usually a rapidly progressive form of dementia
seen with Parkinson syndrome. - VISUAL HALLUCINATION ARE SEEN.
frontal lobe dementia - CORRECT ANSWER -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 ANSWER -Measure brain metabolism of glucose. decreaesd
uptake by temporal and parital lobe in Alzheimer's
