Components - Basic Flashcards
The quality of a product or a service denotes
Fitness for the purpose
Transfusion of thawed FFP is allowed within 6 hours only
False
The buffycoat should be incubated for 24 hours before platelet preparation
False( 2-24 hours n 20-24 C )
The maximum transit time for PRBCs is ———–and temperature should not exceed———— at controlled environment and for whole blood
24 hours - 10 Degrees
24 hours- 20-24 degrees (Room Temp)
White blood cells in filtered PRBCs unit should be less than ———————
0.01 % 5x 10(6)
Additives solutions nutrition for blood during storage as: —————– & —————-
SAGM, MANNITOL& Adsol
Hematocrite of PRBCs should be between ……….&;;………
PRBC"S=60-75% WITH IN ADDITIVE SOLUTION= 50-70% WASHED PRBCS=55-75% PRBCS(BUFFY COAT REMOVED)=50-70% LEUCODEPLETED PRBCS=60-75% LEUCODEPLETED PRBCS(WITH ADDITIVE SOLUTION)=50-75%
The platelet concentrate is stored in the agitator
A) At 20°C-24°C
B) With continous agitation
C) With the label side down
D) All of above ( Correct)
Factor VIII in cryoprecipitate unit should be > 70 IU
True > 80 IU/UNIT
The cryo precipitate contains the following factors:
factor 8,
fibrinogen, von Willebrand factor, factor VIII, factor XIII and fibronectin
Which of the following determine the shelf life of the platelets?
A) Anticoagulant preservative solution
B)Instructions on the bag
C) Type of the blood bag
D) B & C ( correct)
E) All of the above
The platelet concentrate is stored in the agitator
A) At 20°C-24°C
B) With continues agitation
C) All of the above ( correct)
D) With the label side down
The ideal volume of whole blood unit 70 ml to process PRBCs and Plasma is 450-550 ml
True
The ratio of the anticoagulant to the whole blood is
1.4 : 10
The expiry of the PRBCs with the following anticoagulant will be:
CPD…………….
CPDA-1………..
SAGM………….
CPD…………….21
CPDA-1………..35
SAGM………….42
Calculate the number of units of platelets if platelet count was 1800X10*3 and the volume was 200 ml: ……………..
7 units
Life span for open system technique is———– in the fridge and……on the bench
24 hours in the fridge and 6 hours on the bench( Room Temperature)
Always keep the door closed between each run of the centrifuge
To prevent vapor condensation inside the centrifuge
when should you irradiate PRBCs
no longer than 14 days after collection, shelf life is 14 days after irradiation
What should be done if clots are seen up to the third segment of the tube line of the whole blood unit
You should prepare PRBCs and FROZEN PLASMA ..not suitable for platelets, cryoprecipitate fresh frozen plasma
