SECTION I — FETAL PHYSIOLOGY, EFM TECHNIQUES & PATTERN Questions 1 –
INTERPRETATION 50
1. Which of the following factors can have a negative effect on uterine blood flow?
A. Hypertension
B. Epidural
C. Hemorrhage
D. Diabetes
E. All of the above
CORRECT ANSWER E — All of the above
RATIONALE All of these factors can negatively impact uterine blood flow. Hypertension causes maternal vasoconstriction,
reducing blood flow to the uterus. An epidural can cause maternal hypotension (especially supine
hypotension from vena cava compression), decreasing uterine perfusion. Hemorrhage reduces maternal
circulating blood volume, directly decreasing blood available for placental perfusion. Diabetes can cause
vascular changes in the placental bed, impairing uteroplacental blood flow. The common pathway is a
reduction in maternal cardiac output or increased uterine vascular resistance, both of which diminish oxygen
delivery to the fetus. The mother is the source of all fetal oxygenation — anything that affects maternal blood
flow can affect blood flow through the placenta.
, 2. How does the fetus compensate for decreased maternal circulating volume?
A. Increases cardiac output by increasing stroke volume
B. Increases cardiac output by increasing its heart rate
C. Increases cardiac output by increasing fetal movement
CORRECT ANSWER B — Increases cardiac output by increasing its heart rate
RATIONALE The fetus has limited ability to increase stroke volume because the fetal myocardium is relatively non-
compliant (stiff) compared to the adult heart. Therefore, when the fetus needs to increase cardiac output —
as in response to decreased maternal circulating volume or hypoxia — it does so primarily by increasing heart
rate. Fetal cardiac output is approximately equal to heart rate. This is why fetal tachycardia is often a
compensatory response to transient hypoxemia. The fetus also has a higher cardiac output and heart rate
than the adult, resulting in rapid circulation. When the FHR increases, the myocardium consumes MORE
oxygen, which can become problematic if the tachycardia is sustained. The sympathetic nervous system
increases the heart rate and strengthens myocardial contractions through the release of epinephrine and
norepinephrine.
3. Stimulating the vagus nerve typically produces what effect on the fetal heart rate?
A. A decrease in the heart rate
B. An increase in the heart rate
C. An increase in stroke volume
D. No change
CORRECT ANSWER A — A decrease in the heart rate
RATIONALE Stimulation of the vagus nerve (cranial nerve X) activates the parasympathetic nervous system, which
releases acetylcholine. This neurotransmitter slows conduction through the sinoatrial (SA) node, decreasing
the fetal heart rate. The parasympathetic nervous system, through vagal stimulation, reduces FHR and
maintains beat-to-beat variability. The vagus nerve begins maturation at 26–28 weeks' gestation; its
dominance results in a decreased FHR baseline. Early decelerations are a vagal response to head compression
— increased intracranial pressure stimulates the vagus nerve, producing a gradual decrease in FHR that
mirrors the contraction. Variable decelerations also involve a vagal response through baroreceptor
stimulation from cord compression. The sympathetic nervous system has the opposite effect — it increases
FHR through catecholamine release.
