What is the cause of polycythemia in the fetus?
a. Fetal hemoglobin has a greater affinity for oxygen as a
result of diphosphoglycerate (DPG).
b. The fetus has a different hemoglobin structure of two a-
and two y-chains rather than two a-and two b-chains.
c. Increased erythropoiesis occurs in response to the
hypoxic intrauterine environment.
d. The lungs of the fetus are undeveloped and unable to
diffuse oxygen adequately to the pulmonary capillaries. -
ANSWER-Increased erythropoiesis occurs in response to
the hypoxic intrauterine environment.

Why does fetal hemoglobin have a greater affinity for
oxygen than adult hemoglobin?
a. The fetus does not have its own oxygen supply and
must rely on oxygen from the maternal vascular system.
b. The fetus has two -chains on the hemoglobin, rather
than two -chains as in the adult.
c. Fetal hemoglobin interacts less readily with
diphosphoglycerate (DPG), which inhibits hemoglobin-
oxygen binding.
d. Fetal hemoglobin production occurs in the vessels and
liver rather than in the bone marrow as in the adult. -
ANSWER-Fetal hemoglobin interacts less readily with
diphosphoglycerate (DPG), which inhibits hemoglobin-
oxygen binding.
Which blood cell type is elevated at birth and through the
preschool years, but decreases to adult levels afterward?

What is the most common cause of insufficient
erythropoiesis in children?
a. Folic acid deficiency
b. Iron deficiency
c. Hemoglobin abnormality
d. Erythrocyte abnormality - ANSWER-Iron deficiency
How does hemolytic disease of the fetus and newborn
(HDFN) cause acquired congenital hemolytic anemia?
a. HDFN develops when hypoxia or dehydration causes
the erythrocytes to change shapes, which are then
recognized as foreign and removed from circulation.
b. HDFN is an alloimmune disease in which the mother's
immune system produces antibodies against fetal
