100% SOLVED| GRADED A+
1. A newborn is group O, D-positive and has
a 3+ DAT. The mother's antibody
screening test is negative. Assuming the
antibody detection test is valid, one should
consider HDN due to an antibody directed
against
A. Fyb antigen
B. K antigen
C. Low-incidence antigen
D. A or B antigen C. Low-incidence antigen
2. The most conclusive way to demonstrate
the antibody that is causing a positive DAT
in a newborn is to perform an antibody
A. Titration using the mother's serum
B. Panel using the mother's serum
C. Panel using an eluate from the
,mother's red cells
D. Panel using an eluate from the baby's
red cells D. Panel using an eluate from the baby's
red cells
3. Which two of the following conditions are
the most serious immediate consequences
of HDN?
A. Anemia and a positive DAT
B. Hyperbilirubinemia and anemia
C. Hyperbilirubinemia and j aundice
D. Hyperbilirubinemia and kernicterus B. Hyperbilirubinemia and anemia
4. A premature infant with hydrops fetalis
and a bilirubin of 20 mg/dL is referred to
an intensive care unit. The neonatologist
wants to perform an exchange transfusion
to correct anemia and prevent kernicterus.
No blood specimen from the mother is
available. The infant's serum has a
,positive antibody screen. The DAT is 4+.
What would be the best approach in this
situation?
A. Identify the antibody in the serum and
crossmatch blood negative for the
offending antigen, using the serum in
a crossmatch.
B. Issue group O, D-negative blood for
the exchange.
C. Refuse to issue blood for exchange
until a sample can be obtained from
the mother.
D. Identify the antibody in the serum and
eluate and crossmatch blood negative
for the offending antigen, using both
the serum and eluate in a crossmatch. D. Identify the antibody in the serum and
eluate and crossmatch blood negative
for the offending antigen, using both
the serum and eluate in a crossmatch.
195. Which of the following is not true of an
, exchange transfusion when an infant is
suffering from HDN?
5. A. Removes unconjugated bilirubin
B. Reduces the amount of incompatible
antibody in the baby's circulation
C. Removes antibody-coated red blood
cells
D. Provides red blood cells of the baby's
type D. Provides red blood cells of the baby's
type
6. A massive fetomaternal hemorrhage in a
D-negative woman who had a D-positive
infant should be suspected if the
A. Infant is premature
B. Infant has a positive acid elution slide
test
C. Mother requires a transfusion
following childbirth
D. Weak D test on the maternal blood
