HEMATOLOGY FULL QUESTIONS AND
ACCURATE ANSWERS TEST BANK
PREPARATION RESOURCE
●● tubes for collecting blood
Answer: green sodium heparin biochemistry (ammonia, insulin)
purple/lavander EDTA CBC, blod smears, Hba1c, etc
grey fluoride, oxalate glucose, lactate
blue sodium citrate coagulation tests including bleeding time
red clot activator, hormones, toxicology, etc
yellow/gold serum separating urea and electrolytes, liver function, c-
reactive protein, etc
●● The purple tubes contain EDTA as an additive, which is strong
anticoagulant. WHats a role of an anticoagulant in hematolgy?
Answer: prevent blood clotting
●● Whichcomponent of the blood is responsible for blood clotting?
Answer: platelets/ thrombocytes
●● what's the role of the red blood cells?
Answer: transport of O2 from the lungs
, take up oxygen in the lungs and deliver it to all kinds of tissues in the
body.
●● WHat are neutrophils, eosinophils, basophils, lmphocytes and
monocytes?
Answer: they are all white blood cells also called leukocytes
●● hematocrit
Answer: the volume of red blood cells is also defined as hematocrit.
after centrifugation, two layers can be seen. the upper phase consists of
the yellowis plasma. RBC sink to the bottom of the tube after centrifuge
as a red lower layer. WBC and platelets setlles in the interface between
both layers.
●● According to the sample blood count of the control sample, how
many red blood cells are present in the tube, considered that the tube
contains 10 ml of blood?
Answer: 5.1 x 10 10
●● THe measure hematocrit of the control sample is 42. WHat's the
percentage of blood plasma?
Answer: 58 hematocrit and plasma make up almost 100%. the buffy
coat, composed of WBC and platelets compose less than 1%
