RED CELL SUSPENSION PREPARATION

Question 1

In practice, how many percent of RCS volume per volume concentration is prepard?

Answer 1

2-5% RCS

Question 2

What is the diluent used for RCS preparation?

Answer 2

NSS

Question 3

The NSS diluent used for RCS preparation must be isotonic

True or False

Answer 3

TRUE

Question 4

The NSS diluent used for RCS preparations must be how many percent of a salt solution?

Answer 4

0.85 to 0.9% salt solution

Question 5

In the absence of NSS, what will you use?

Answer 5

• Blood type AB serum
• Bovine albumin

Question 6

In preparing RCS, what will you need?

Answer 6

• washed packed RBC
• Diluent (NSS)

Question 7

What is the computation in calculating the concentration desired in preparing RCS?

Answer 7

TV RCS = PCV / %RCS concentration X 100

To calculate the TOTAL VOLUME OF RCS

Question 7

What is the computation in calculating the concentration desired in preparing RCS?

Answer 7

TV RCS = PCV / %RCS concentration X 100

To calculate the TOTAL VOLUME OF RCS

Question 8

What is the formula to calculate the volume of the diluent

Answer 8

TV of Diluent = TV RCS - PCV

To calculate the VOLUME OF THE DLUENT
