ANSWERS COMPLETE AND VERIFIED.
Which class of immunoglobulin has four subclasses?

The secret or locus is linked to which blood group locus?
Correct Answer -Lewis
Which of the following statements is true concerning the MN genotype?
Correct Answer -Dosage effect may be seen for both M and N antigens
A group O, Rh-positive patient experienced a delayed transfusion reaction. The
post-reaction specimen demonstrated anti-c. Select the most appropriate donor
genotype for further red cell transfusions.
Correct Answer -Cde/CDe
ll of the following antibodies are considered to be clinically significant except:
Question 20 options:
a)
Anti-K
b)
Anti-Leb
,c)
Anti-Jka
d)
Anti-A
Correct Answer -Anti-Leb
Polyspecific reagents used in the direct antiglobulin test should have specificity
for:
Correct Answer -IgG and C3d
When performing a direct antiglobulin test using polyspecific AHG, no
agglutination is detected using IgG-coated cells (check cells). This test should be
considered:
Correct Answer -Invalid; repeat the entire direct antiglobulin procedure
Before blood is issued for transfusion, a patient's previous blood bank records
must be reviewed for all the following except:
a)
ABO group and Rh type
b)
Clinically significant antibodies
c)
Hepatitis testing
d)
,Serious adverse reactions
Correct Answer -Hepatitis testing
A test tube containing known antibody and unknown cells has been incubated
and spun. After dislodging the cell button completely, several large agglutinates
are apparent with no small clumps or free cells visible. The background solution
is clear. This reaction should be graded as:
Correct Answer -3+
Which of the following red cell antigens are found on glycophorin A?
Question 25 options:
a)
Lea, Leb
b)
P, P1
c)
M, N
d)
S,s
Correct Answer -M, N
S is on glyco B
When the main objective of an exchange transfusion is to remove the infant's
antibody-sensitized red blood cells and to control hyperbilirubinemia, the blood
, product of choice is ABO compatible:
Correct Answer -fresh whole blood
A patient has the phenotype O, CDEe. If transfused with blood from six random
group O, Rh positive donors, the patient could theoretically produce the antibody:
Correct Answer -Anti-c
you only form antibody to the antigens you lack
Whole blood collected in citrate-phosphate-dextrose with adenine (CPDA-1) may
be stored for up to:
Correct Answer -35 days
How long after transfusion must a sample from the donor unit be retained in the
transfusion service?
Correct Answer -7 days
What blood type is not possible for an offspring of AO and BO mating?
Correct Answer -All are possible
The crossmatch can be limited to procedures to detect ABO compatibility if:
Correct Answer -The recipient currently has a negative antibody screen and no
previous history of an unexpected antibody
The process of separation of antibody from its antigen is known as:
Correct Answer -elution
