NP Hematology Exam Questions And Correct Answers
Normal Hemoglobin - ANSWER Men: 14-18
Women: 12-16
Normal Hematocrit - ANSWER Men 40-54%
Women: 37-47%
Total Iron Binding Capacity (TIBC) - ANSWER Normal 250-450
Serum Iron - ANSWER Normal 50-150
Mean Corpuscular volume
CYTIC - ANSWER Expression of the average volume and size of individual erythrocytes
Normocytic 80-100
Microcytic - less than 80
Macrocytic - greater than 100
Mean Corpuscular Hemoglobin (MCH) - ANSWER Expression of the average amount
and weight of Hgb contained in a single erythrocyte
Normal 24-34
Mean Corpuscular Hemoglobin Concentration (MCHC)
CHROMIC - ANSWER Expression of the average Hgb concentration or proportion of
each RBC occupied by Hgb as a percentage; more accurate than MCH
Normochromic: 32-36%
Hypochromic: less than 32%
Low MCV (mean corpuscular volume) - ANSWER Iron deficiency anemia or Thalassemia
, High MCV (mean corpuscular volume) - ANSWER B12 or folate deficiency; alcoholism,
liver failure, drug effects
Normocytic but low H/H - ANSWER Anemia of chronic disease, sickle cell disease, renal
failure, blood loss, and hemolysis
Iron deficiency anemia - ANSWER MICROCYTIC, HYPOCHROMIC
-Most common cause of anemia
-iron loss exceeds intake and storage is depleted, not available for RBC formation
-Blood loss, inadequate intake, impaired absorption of Iron
S/Sx - usually not until Hct less than 30
-Pica: unusual food cravings
-Dyspnea and mild fatigue with exercise
-HA
-Palpitations
-Weakness
-Tachycardia
-Postural hypotension
-pallor
Iron deficiency anemia labs and management - ANSWER Labs:
LOW: RBC, Hgb, Hct, MCV (microcytic) MCHC (hypochromic), serum iron, serum ferritin
HIGH: TIBC (total iron binding capacity), RDW (Red cell distribution width
Managment:
