C-EFM PRACTICE QUESTIONS AND
100% CORRECT VERIFIED ANSWERS
/GRADE A
n 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 - C. Timjng in relation to ctx
The underlying cause of early decelerations is decreased
A. Baroreceptors response
B. Increased peripheral resistance
C. Vagal reflex -
Betamethasone can increase or decrease FHr - 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 - C. Varied in depth and duration
What do respiratory acidosis and metabolic acidosis have in common? - Low pH
Doppler technology use sounds waves to reflect
A. Electric waves
, B. Movement
C. Sound - 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 - Poly - May scatter sound waves
BPP...if it decreases what is the last item remaining?
A. breathing
B. Movement
C. Tone - 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
If AMniotic fluid listed as Choice it would be the last to go away. Amniotic fluid decreases as a
compensatory mechanism due to shunting
What is the function of intervillous space? - Ensuring fetal reserve
What do moderate variability or accels predict? - Reliably predict a well oxygenated fetus
Betamethasone causes the HR to
A. No change
B. Increase
C. Decrease - C. Decrease
