c. Autoimmune disease in immature nucleated cells that are released into the
bloodstream

d. Alloimmune disease in which maternal blood and fetal blood are antigenically
incompatible –
Correct Answer :d. Alloimmune disease in which maternal blood and fetal blood
are antigenically incompatible
Rationale: Erythroblastosis fetalis, also known as hemolytic disease of the fetus
and newborn (HDFN), is an alloimmune disease in which maternal blood and
fetal blood are antigenically incompatible, causing the mother's immune system
to produce antibodies against fetal erythrocytes. This selection is the only
option that accurately defines erythroblastosis fetalis.
A newborn displays pallor, tachycardia, and has a systolic murmur. What
hemoglobin value does the healthcare professional correlate with these
manifestations?
a. 9 g/dL
b. 11 g/dL
c. 5 g/dL
d. 7 g/dL –
Correct Answer :c. 5 g/dL
Rationale: When the hemoglobin falls below 5 g/dL, pallor, tachycardia, and
systolic murmurs may occur.

A child has iron deficiency anemia. In addition to iron supplements, what else
does the healthcare professional educate the parents on giving the child?
a. Magnesium
b. Vitamin C
c. Vitamin A
d. Zinc –
Correct Answer :b. Vitamin C
Rationale: Vitamin C helps with absorption of iron, so the healthcare
professional instructs the parents about giving it to the child with iron deficiency
anemia. Vitamin A, magnesium, and zinc do not help promote the absorption of
iron.
Which mother does the healthcare professional prepare to administer Rh
immune globulin (Rho-GAM) to?
a. Is Rh-negative and the fetus is Rh-positive
b. Is Rh-positive and the fetus is Rh-negative
c. Has type AB blood and the fetus has type B
d. Has type A blood and the fetus has type O –
Correct Answer :a. Is Rh-negative and the fetus is Rh-positive

PATHOPHYSIOLOGY
Rationale: Hemolytic disease of the fetus and newborn (HDFN) can occur only if
antigens on fetal erythrocytes differ from antigens on maternal erythrocytes.
Maternal-fetal incompatibility exists only if the mother and fetus differ in ABO
blood type or if the fetus is Rh-positive and the mother is Rh-negative. The
healthcare professional would plan to administer Rho-GAM to the mother who
is Rh-negative whose baby is Rh positive.
When diagnosed with hemolytic disease of the fetus and newborn (HDFN), why
does the newborn develop hyperbilirubinemia after birth but not in utero?
a. The destruction of erythrocytes producing bilirubin is greater after birth.
b. Excretion of unconjugated bilirubin through the placenta into the mother's
circulation is no longer possible.
c. The liver of the fetus is too immature to conjugate bilirubin from a lipid-soluble
to water-soluble form.
d. Hemoglobin does not breakdown into bilirubin in the intrauterine
environment. –
Correct Answer :b. Excretion of unconjugated bilirubin through the placenta into
the mother's circulation is no longer possible.
Rationale: Hyperbilirubinemia occurs in the neonate after birth because
excretion of lipid-soluble unconjugated bilirubin through the placenta is no
longer possible. HDFN is not related to hemoglobin failing to breakdown, an
immature liver, or destruction of erythrocytes being greater after birth.
The healthcare professional is caring for a woman whose baby died of hydrops
fetalis. How does the professional explain this condition to a student?
