NCC EFM Exam Questions and Answers
(2026/2027) | Study Guide Pack | Accurate
Solutions | A+
• Category I FHR -✓✓Normal FHR ruling out fetal acidemia, maternal-fetal
complications, instrumentation, medications, arrhythmias
• FHR Tracings Speed -✓✓3cm/min speed for EFM tracings during the
exam
• Adequacy of Fetal Oxygenation -✓✓Exam topic covering FHR patterns,
acid-base status, intrauterine resuscitation
• Fetal Oxygenation Pathway -✓✓Maternal-fetal exchange pathway
ensuring FHR regulation and oxygenation
• Oxygen Transport Physiology -✓✓Supporting fetal oxygenation with
maternal hemoglobin, O2 saturation, arterial O2 tension
• Uteroplacental Blood Flow -✓✓Critical for healthy newborn, increases
during pregnancy to 700 ml/min
• Mechanisms of Exchange -✓✓Processes like diffusion, bulk flow,
facilitated diffusion, active transport in maternal-fetal blood exchange
• Uterine Blood Flow Diffusion -✓✓Determines passage of critical
substances across the placenta
• Factors Decreasing Blood Flow -✓✓Clinical factors like excessive uterine
activity, maternal hypotension, conditions affecting uteroplacental
exchange
• Placental Changes -✓✓Factors affecting uteroplacental exchange,
including maternal conditions and placental changes
, • Oxygen Depletion Cascade -✓✓Pathway from aerobic to anaerobic
metabolism leading to potential fetal injury
• Fetal Oxygenation Requirements -✓✓Factors ensuring normal fetal
circulation and FHR regulation for adequate oxygenation
• Umbilical Blood Flow -✓✓Considerations for fetal oxygenation and
umbilical cord perfusion
• Aerobic Metabolism -✓✓Metabolic process utilizing oxygen for energy
production
• Hypoxemia -✓✓Low oxygen levels in the blood
• Anaerobic Metabolism -✓✓Metabolic process without oxygen, leading to
lactic acid build-up
• Tissue Hypoxia -✓✓Low oxygen levels in body tissues
• Lactic Acid Build Up -✓✓Accumulation of lactic acid due to anaerobic
metabolism
• Metabolic Acidosis -✓✓Acidosis resulting from metabolic processes
• Potential Injury -✓✓Risk of harm due to interruption in oxygen pathway
affecting FHR regulation and circulation
• Ductus venosus -✓✓A shunt in fetal circulation that allows oxygenated
blood from the umbilical vein to bypass the liver and flow directly to the
inferior vena cava
• Foramen ovale -✓✓An opening between the atria in the fetal heart that
allows blood to flow from the right atrium to the left atrium, bypassing the
pulmonary circulation
• Ductus arteriosus -✓✓A connection between the pulmonary artery and
the aorta in fetal circulation, allowing most blood to bypass the lungs
