APHERESIS/HEMAPHERESIS

Question 1

used as the primary anticoagulant in apheresis procedures

a. rejuvesol
b. glycerol
c. citrate
d. adenine

Answer 1

citrate

Question 2

is a procedure in which whole blood is removed from the body and passed through an apparatus that separates out one (or more) particular blood constituent.

Answer 2

apheresis

Question 3

citrate toxicity if not attended it will lead to

a. cardiac arrhythmias
b. syncope
c. tetany
d. hemolysis

Answer 3

Citrate toxicity -Most common reaction. Donor may feel numbness or tingling around the mouth (paresthesias). If unattended, the symptoms can lead to tetany (due to hypocalcemia) and cardiac arrhythmia.

Question 4

the idea of apheresis is developed by

a. karl landsteiner
b. levine
c. dr. edwin cohn
d. robert koch

Answer 4

The idea of apheresis was developed by Dr.Edwin J. Cohn

Question 5

A platelet donor typically experiences an acute fall in platelet count of __ following apheresis donation

a. 20%
b. 22%
c. 20-22%
d. 20-29%

Answer 5

A platelet donor typically experiences an acute fall in platelet count of 20 - 29% following apheresis donation

Question 6

Typically, a drop in hematocrit of __ and a fall in platelet count of 22% occur after each granulocyte donation.

a. 1%
b. 2%
c. 3%
d. 5%

Answer 6

Typically, a drop in hematocrit of 3% and a fall in platelet count of 22% occur after each granulocyte donation.

Question 7

the amount of time of apheresis procedure

a. 15 minutes
b. 30 minutes
c. 40 minutes
d. 2 hours

Answer 7

The donor or patient remains attached to the apheresis instrument for the duration of the procedure; the amount of time for a particular procedure can range from 45 to 120 minutes. Collection of hematopoietic progenitor cells takes considerably longer.

Question 8

methods of separation that Requires only one venipuncture, in which blood is withdrawn and reinfused through the same needle.

a. intermittent flow centrifugation
b. continuous flow centrifugation
c. membrane filtration

Answer 8

Intermittent flow centrifugation
• Requires only one venipuncture, in which blood is withdrawn and reinfused through the same needle. Once the desired component is separated, the remaining components are reinfused to the donor, and one cycle is complete

Question 9

methods of centrifugation that has a Procedures withdraw, process, and return the blood to the individual simultaneously.

a. intermittent flow centrifugation
b. continuous flow centrifugation
c. membrane filtration

Answer 9

Continuous flow centrifugation
• Procedures withdraw, process, and return the blood to the individual simultaneously.
• Two venipuncture sites are necessary
