Q

Should you use containers containing serum separator? Why or why not?

A

Do not use tubes containing serum separator because the gel may cause insipient coating of the red blood cell.

11
Q

Why do we perform cross-matching prior to blood transfusion?

A

to ensure that there are no
antibodies present in patient’s serum that will react with
donor’s cells when transfused

(to prevent hemolytic reactions)

Q

T/F:
In major cross-match, Immediate Spin Method or Saline Room Temperature Technique is not enough to rule out any ABO grouping error.

IAT is further used to identify clinically significant igG type of antibodies

A

False; True
Immediate Spin Method or Saline Room Temperature are ENOUGH to rule out any ABO grouping error. But IAT is further used to identify clinically significant igG type of antibodies

CPD: Citrate-phosphate dextrose
CP2D: Citrate-phosphate-double-dextrose
CPDA-1: Citrate-phosphate-dextrose-adenine

21
Q

Storage time for ACD-A: Acid citrate-dextrose (formula A)

22
Q

Storage time for CPD: Citrate-phosphate dextrose

23
Q

Storage time for CP2D: Critrate-phosphate-double-dextrose

24
Storage time for CPDA-1: Citrate-phosphate-dextrose-adenine
35 days
25
Enumerate the procedure for arms preparation prior to blood transfusion.
1. Scrub the site (2 × 2 inches) for 30 seconds using an aqueous iodophor scrub solution (0.7%). 2. Apply iodophor complex and let stand for 30 seconds. 3. Cover with sterile gauze until ready for needle insertion.
26
Procedure for preparing the balance system.
Ensure the balance system is adjusted to the volume being drawn; ensure counterbalance is level. Place hemostats on the tubing to prevent air from entering the line.
27
a compact instrument that provides smooth and gentle rocking for homogenous mixing with the anticoagulant in the blood bag
Blood collection monitor
28
Release the hemostat, and ask the donor to open and close the hand every ___-___ seconds during collection procedure.
10-12
29
A unit containing a volume of 405 to 550 mL should weigh between ____-____g, plus the weight of the container and anticoagulant.
429-583
30
Remove the needle from the donor’s arm, apply pressure over gauze, and ask the donor to (raise or lower?) his or her arm, continuing to exert pressure over the site.
raise
31
When can the donor lower his or her arm?
When the bleeding has stopped, the donor can lower his or her arm, and an appropriate bandage can be applied.
32
T/F: The needle assembly should be discarded into an appropriate biohazard receptacle. The tubing should be stripped to allow proper mixing of anticoagulant/ preservative with blood.
Both true
33
What should be done to the filled tubing?
Heat seal the filled tubing into segments, and apply an appropriate identification label to one segment and detach from the blood bag for storage.
34
Units in which platelets will be made must be maintained at what temperature?
room temperature (20°C to 24°C)
35
What are the possible donor reactions?
● Nervousness ● Hematoma ● Nausea ● Convulsions ● Loss of Consciousness
36
Severity of Donor Reactions
Mild Moderate Severe
37
DOs after blood donation
Treat yourself. Stay bandaged. Keep cool. Schedule another appointment.
38
Don'ts after blood donation
Smoke Exercise Drink alcohol Stand in lines
39
Wait for at least how many hours after blood donation before exercising?
5 hours
40
Go for water over alcohol for at least how many hours after donating?
24 hours
