HEMATOLOGY UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
COMPLETE STUDY GUIDE
●● Oxygen saturation
Answer: The ratio of oxygen bound to hemoglobin
Measured with a pulse oximeter
●● 2,3 DPG
Answer: This enzyme stimulates oxygen release from hemoglobin when
blood pH is low (hypoxic/acidotic).
●● Carboxyhemaglobin
Answer: Hemoglobin disorder in which hgb has a higher affinity for
carbon monoxide than for oxygen. The Oxygen-Hemoglobin curve shifts
left, patient is hypoxemic, and blood appears bright red.
●● Methemoglobin
Answer: Hemoglobin disorder in which the iron molecule of hgb is
oxidized into Fe+3, causing a left shift in the Oxygen-Hemoglobin
curve. Blood becomes brown colored.
●● Erythropoiesis
, Answer: The production and formation of red blood cells
●● Reticulocyte
Answer: The stage of red blood cell development just prior to maturation
●● Metarubricyte
Answer: A red blood cell more immature than a reticulocyte
●● Rubriblast
Answer: The most immature stage of red blood cell development
●● Leukocytosis
Answer: Medical term for an increase in white blood cells
●● Leukopenia
Answer: Medical term for a decreased number of white blood cells
●● Neutrophil
Answer: Granulocyte that functions in phagocytosis, secretion of
mediators of inflammation, antibacterial properties, and microbiocidal
action
●● Eosinophil
