✍️ Sample EFM Questions & Answers

1. When documenting a category II fetal heart rate tracing, what is the MOST important element to record?

✓ Interventions performed and fetal response

Documenting the interventions performed and the fetal response demonstrates clinical action taken and establishes a clear record for continuity of care.

2. During a uterine contraction, blood flow through the uterine spiral arteries temporarily decreases. What is the primary reason for this reduction in flow?

✓ Increased intramyometrial pressure compressing the vessels

Uterine contractions increase the pressure within the myometrium (intramyometrial pressure). This increased pressure compresses the spiral arteries that perfuse the intervillous space of the placenta. When the intramyometrial pressure exceeds the pressure within the arteries, blood flow is significantly reduced or even temporarily stopped, leading to a transient decrease in oxygen transfer to the fetus.

3. A normal umbilical artery bicarbonate (HCO3-) level at delivery is approximately:

✓ 22 – 26 mEq/L

Normal umbilical artery bicarbonate is approximately 22–26 mEq/L, reflecting adequate bicarbonate buffering capacity in the fetus at delivery.

4. Which type of acidosis is characterized by an elevated PCO2 and normal base deficit in fetal cord blood?

✓ Respiratory acidosis

Respiratory acidosis results from acute CO2 accumulation (elevated PCO2) without significant base deficit, often due to transient cord compression.

5. Which EFM pattern is classically associated with complete placental abruption?

✓ Prolonged deceleration or sudden bradycardia with loss of variability

Complete placental abruption causes sudden cessation of uteroplacental blood flow, producing a prolonged deceleration or sustained bradycardia with loss of variability.

6. When documenting fetal heart rate accelerations, which detail is required to meet the standard NICHD definition in a term fetus?

✓ Peak ≥15 bpm above baseline lasting ≥15 seconds

In a term fetus, an acceleration is defined by NICHD as a peak of at least 15 bpm above baseline with a duration of at least 15 seconds.
