## SECTION 1: FETAL PHYSIOLOGY & CIRCULATION (Questions 1–25)
**1. Which of the following is an extrinsic influence on the fetal heart rate
(FHR)?**
A. Fetal autonomic nervous system
B. Fetal chemoreceptors
C. Fetal-placental circulation
D. Fetal baroreceptors
**Correct Answer: C**
**Rationale:** Extrinsic influences on the FHR are factors outside the fetus that
affect the heart rate, including the fetal-placental circulation, maternal oxygenation,
uterine blood flow, and placental exchange. Intrinsic influences (A, B, D) originate
within the fetus, such as the autonomic nervous system, chemoreceptors, and
baroreceptors .
---
**2. The most highly oxygenated blood in fetal circulation is carried by:**
A. Umbilical artery
B. Portal vein
C. Ductus venosus
D. Inferior vena cava
**Correct Answer: C**
,3|Page
**Rationale:** The ductus venosus carries the most highly oxygenated blood in
fetal circulation. It shunts oxygenated blood from the umbilical vein directly to the
inferior vena cava, bypassing the liver, allowing the highest oxygen content to
reach the fetal heart and brain .
---
**3. If fetal arterial pressure begins to fall below normal levels:**
A. Baroreceptors cause vasoconstriction and increase the FHR
B. Baroreceptors cause vasodilation and decrease the FHR
C. Chemoreceptors cause vasoconstriction and decrease the FHR
D. Chemoreceptors cause vasodilation and increase the FHR
**Correct Answer: A**
**Rationale:** When fetal arterial pressure falls below normal, baroreceptors
(pressure sensors) in the aortic arch and carotid sinuses detect the decrease and
trigger a compensatory response: vasoconstriction and increased heart rate to
restore perfusion pressure. This is a protective mechanism to maintain blood flow
to vital organs .
---
**4. Fetal heart rate variability is defined as fluctuations in the baseline that are
irregular in _____ and _____.**
A. Duration and depth
, 4|Page
B. Amplitude and frequency
C. Timing and rhythm
D. Speed and pattern
**Correct Answer: B**
**Rationale:** Variability refers to the irregular fluctuations in the FHR baseline
measured in terms of amplitude (the height of the fluctuations in beats per minute)
and frequency (the number of fluctuations per minute). Normal variability
indicates an intact, well-oxygenated central nervous system .
---
**5. An increase in the fetal heart rate immediately preceding a variable
deceleration is caused by:**
A. Occlusion of the umbilical vein
B. Occlusion of the umbilical artery
C. Head compression
D. Uteroplacental insufficiency
**Correct Answer: A**
**Rationale:** The initial "shoulder" (acceleration) before a variable deceleration
occurs when the thin-walled umbilical vein is compressed first, reducing venous
return to the right atrium. This triggers a compensatory tachycardia via sympathetic
nervous system activation before the arteries are compressed, causing the
deceleration .
