1. In comparison to maternal blood, the affinity of fetal blood
for oxygen is:
A) Higher
B) Lower
C) The same
D) Variable depending on gestational age
Correct Answer: A
Rationale: Fetal hemoglobin (HbF) has a higher affinity for
oxygen than adult hemoglobin (HbA). This allows the fetus to
1
,extract oxygen from the maternal circulation across the
placenta. The oxygen-hemoglobin dissociation curve is shifted to
the left in the fetus .
2. Fetal hypoxia is best described as a condition of:
A) Decreased oxygen in the blood (hypoxemia)
B) Decreased oxygen in the tissue
C) Increased hydrogen ions in the blood
D) Decreased carbon dioxide in the blood
Correct Answer: B
Rationale: Hypoxia refers to decreased oxygen at the tissue
level, while hypoxemia refers to decreased oxygen in the blood.
In fetal monitoring, we are concerned with tissue hypoxia that
can lead to metabolic acidosis and potential neurologic injury .

,3. The umbilical vein carries:
A) Carbon dioxide from the fetus back to the placenta
B) Deoxygenated blood from the fetus to the placenta
C) Oxygenated blood from the placenta to the fetus
D) Mixed venous blood from the placenta to the fetus
Correct Answer: C
Rationale: The umbilical vein carries oxygenated, nutrient-rich
blood FROM the placenta TO the fetus. The two umbilical
arteries carry deoxygenated blood and waste products FROM
the fetus TO the placenta .
4. Stimulation of the parasympathetic nervous system (PNS) via
the vagus nerve causes the FHR to:
3
, A) Decrease
B) Increase
C) Remain the same
D) Become irregular
Correct Answer: A
Rationale: Parasympathetic (vagal) stimulation releases
acetylcholine, which decreases the firing rate of the sinoatrial
(SA) node, resulting in a decrease in FHR. This is the primary
mechanism for baseline heart rate regulation .
5. Chemoreceptors respond mainly to changes in:
A) Blood pressure
B) Hormonal levels
