AWHONN ADVANCED FETAL
MONITORING COMPLETE EXAMINATION
TEST QUESTIONS WITH VERIFIED
SOLUTIONS
●● Electronic fetal monitoring (EFM)
Answer: Continuous or intermittent electronic assessment of fetal heart
rate and uterine activity.
●● Fetal surveillance
Answer: Assessment of fetal well-being using methods such as
intermittent auscultation, EFM, NST, BPP, and other appropriate
assessments.
●● Primary purpose of FHR monitoring
Answer: To identify patterns that may indicate fetal intolerance of labor
or impaired fetal oxygenation.
●● Important limitation of FHR monitoring
Answer: FHR is an indirect indicator of fetal oxygenation and acid-base
status; it does not directly measure fetal oxygen or pH.
●● AWHONN physiologic framework
,Answer: Interpret the FHR in the context of maternal status, uterine
activity, placental function, fetal physiology, and the clinical situation.
●● Fetal oxygenation pathway
Answer: Maternal oxygenation → maternal circulation → uterine blood
flow → placental perfusion → placental gas exchange → umbilical
circulation → fetal oxygenation.
●● Uteroplacental perfusion
Answer: Blood flow from the maternal circulation through the uterus
and placenta that provides oxygen and nutrients to the fetus.
●● Intervillous space
Answer: Maternal blood-filled space within the placenta where
maternal-fetal gas and nutrient exchange occurs across the placental
interface.
●● Fetal oxygen delivery
Answer: Depends on adequate maternal oxygenation, uteroplacental
perfusion, placental exchange, fetal circulation, and fetal hemoglobin.
●● Maternal oxygenation
Answer: Adequate maternal oxygen saturation and oxygen-carrying
capacity are necessary for fetal oxygen delivery.
,●● Maternal cardiac output
Answer: Amount of blood pumped by the heart per minute; affects
uterine perfusion.
●● Uterine blood flow
Answer: Blood supplied to the uterus and placenta; critical for fetal
oxygenation.
●● Placental perfusion
Answer: Adequate maternal blood flow through the placenta for oxygen
and nutrient exchange.
●● Placental gas exchange
Answer: Movement of oxygen from maternal blood to fetal blood and
carbon dioxide from fetal to maternal blood.
●● Fetal hypoxemia
Answer: Decreased oxygen content in fetal blood.
●● Fetal hypoxia
Answer: Inadequate oxygen availability at the tissue level.
, ●● Fetal acidemia
Answer: Abnormally low fetal blood pH resulting from accumulation of
acids, particularly when anaerobic metabolism persists.
●● Fetal acid-base status
Answer: Balance between acids and bases in fetal blood; influenced by
oxygenation and metabolic/respiratory processes.
●● Anaerobic metabolism
Answer: Cellular metabolism that occurs when oxygen availability is
insufficient; produces lactate and contributes to metabolic acidosis.
●● Metabolic acidosis
Answer: Acidosis caused primarily by accumulation of metabolic acids
such as lactate during prolonged inadequate oxygenation.
●● Respiratory acidosis
Answer: Acidosis caused by accumulation of carbon dioxide.
●● Fetal compensation for hypoxemia
Answer: Redistribution of blood flow toward vital organs such as the
brain, heart, and adrenal glands.
