Question 1
A 32-year-old G2P1 at 39 weeks gestation is admitted in active labor. The fetal heart rate tracing shows a
baseline of 135 bpm with moderate variability and occasional early decelerations. What is the most appropriate
initial management?
A. Begin oxygen at 10 L/min via nonrebreather mask
B. Prepare for immediate cesarean delivery
C. Continue routine labor management and monitor
D. Administer terbutaline 0.25 mg subcutaneously
Answer: C
Early decelerations are a Category I finding reflecting head compression and are benign; no intervention is
needed beyond continued monitoring.
Question 2
According to NICHD terminology, which FHR baseline range is considered normal?
A. 100-150 bpm
B. 110-160 bpm
C. 120-180 bpm
D. 90-140 bpm
1|Page
,Answer: B
NICHD defines normal baseline FHR as 110-160 bpm; values outside this range are classified as bradycardia or
tachycardia.
Question 3
A fetal heart rate tracing shows a baseline of 155 bpm, moderate variability, and recurrent variable
decelerations dropping to 80 bpm lasting 45 seconds each. The decelerations resolve with maternal position
change. What is the classification of this tracing?
A. Category I
B. Category II
C. Category III
D. Cannot be determined
Answer: B
Recurrent variable decelerations with moderate variability constitute Category II; the tracing is indeterminate
but not frankly abnormal.
Question 4
Which of the following is the most reliable indicator of fetal acid-base status at the time of observation?
A. Baseline FHR
B. Presence of accelerations
C. Moderate variability
D. Absence of decelerations
Answer: C
2|Page
,Moderate variability (6-25 bpm) is the single most predictive finding of a well-oxygenated fetus with normal
acid-base balance.
Question 5
A patient at 41 weeks gestation is undergoing induction with oxytocin. The FHR tracing shows a baseline of 140
bpm, minimal variability, and recurrent late decelerations. What is the appropriate next step?
A. Increase oxytocin infusion rate
B. Reposition the patient and administer oxygen
C. Discontinue oxytocin and notify provider
D. Perform fetal scalp stimulation
Answer: C
Recurrent late decelerations with minimal variability represent a Category II tracing concerning for
uteroplacental insufficiency; oxytocin should be discontinued and the provider notified.
Question 6
What is the primary mechanism of oxygen transfer from mother to fetus?
A. Active transport across the placental membrane
B. Passive diffusion down a concentration gradient
C. Facilitated diffusion via carrier proteins
D. Pinocytosis through trophoblastic cells
Answer: B
Oxygen crosses the placenta by passive diffusion from the maternal to fetal circulation, driven by the partial
pressure gradient.

, Question 7
A fetal scalp electrode (FSE) measures fetal heart rate by detecting:
A. The Doppler shift of ultrasound waves
B. The R-to-R intervals of the fetal ECG
C. The peak systolic pressure of fetal cardiac contraction
D. The oxygen saturation of fetal blood
Answer: B
The FSE detects the R-to-R intervals of the fetal electrocardiogram, providing accurate beat-to-beat assessment
of fetal heart rate.
Question 8
Which uterine contraction characteristic CANNOT be accurately assessed by external tocodynamometry?
A. Frequency
B. Duration
C. Intensity
D. Resting tone
Answer: D
External tocodynamometry measures frequency and duration but cannot accurately assess intensity or resting
tone; these require an intrauterine pressure catheter.
Question 9
A 28-year-old G1P0 at 38 weeks presents with ruptured membranes and thick meconium-stained fluid. The FHR
shows recurrent variable decelerations to 70 bpm lasting 60 seconds that do not resolve with position changes.
Which intervention is most appropriate?
