NURS 5461 EXAM 1 Questions
and Answers 100% Pass
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.
