INTERMEDIATE FETAL MONITORING TEST
COMPREHENSIVE QUESTIONS AND CORRECT
ANSWERS
◉ 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.
