C-EFM Practice test questions 2026
Exam Questions and verified Answers
In comparing early and late decelerations, a distinguishing factor between the two is
A. Onset time to the nadir of the deceleration
B. The # of decels that occur
C. Timing in relation to contractions - CORRECT ANSWERS C. Timjng in relation to ctx
The underlying cause of early decelerations is decreased
A. Baroreceptors response
B. Increased peripheral resistance
C. Vagal reflex - CORRECT ANSWERS
Betamethasone can increase or decrease FHr - CORRECT ANSWERS Decrease
Following an ultrasound which revealed decreased amniotic fluid, a woman at term is admitted in
early labor. It should be recognized that oligohydramnios often results in FHR decels that are
A. Late in onset or occur after peak of contraction
B. Synchronous with that of contractions
C. Varied in depth and duration - CORRECT ANSWERS C. Varied in depth and duration
What do respiratory acidosis and metabolic acidosis have in common? - CORRECT ANSWERS
Low pH
Doppler technology use sounds waves to reflect
A. Electric waves
B. Movement
C. Sound - CORRECT ANSWERS B. Movement - Doppler technology uses sound waves
to reflect off of anything that moves
Doppler sounds can be deterred by
A. Poly
B. Maternal positioning - CORRECT ANSWERS Poly - May scatter sound waves
BPP...if it decreases what is the last item remaining?
A. breathing
B. Movement
C. Tone - CORRECT ANSWERS C. Tone (BPP behaviors disappear in the reverse order in
which they appeared)
Fetal tone is the first to develop 7.5-8 weeks
Fetal movement begins at 9 weeks - 3rd to disappear
Fetal breathing becomes regular at 20-21 weeks - 2nd to disappear
Reactivity happens at the end of 2nd beginning of 3rd trimester - first to disappear
