29
Q

Series of procedures designed to ensure the safety of transferring blood

A

crossmatching

30
Q

Blood typing and crossmatching must be done to prevent harmful transfusion reactions between the recipient and donor blood. True or False

A

True

31
Q

It must be performed before the transfusion of blood components containing red blood cells

A

crossmatching

32
Q

the patient serum is mixed with the donor red blood cells to find out if a reaction will happen

A

major crossmatch

33
Q

the patient red blood cells are mixed with the donor serum to find out if a reaction will happen

A

minor crossmatch

34
Q

It detects if there are antibodies in the patient serum that can destroy the transfused red blood cells from the donor

A

major crossmatch

35
Q

detects if there are antibodies in the donor serum that can destroy the patient’s red blood cells.

A

minor crossmatch

36
Q

If the major crossmatch is positive and the minor crossmatch is negative the blood is compatible with the patient. True or False

A

False (incompatible)

37
Q

If the minor crossmatch is positive and the major crossmatch is negative the blood is compatible with the patient but only the PRBC. True or False

A

True

38
Q

If both of the minor and major crossmatch are positive, the blood is compatible with the patient. True or False

A

False (incompatible)
