Fetal Heart Monitors Questions with
Complete verified correct detailed
Solutions latest update 2025
amplitude range is detectable but ≤ 5 beats/minute --- correct answer
---Minimal FHR variability
undetectable --- correct answer ---Absent FHR variability
between 6 and 25 beats/minute --- correct answer ---Moderate FHR
variability
amplitude range is greater than 25 beats/minute. --- correct answer --
-Marked FHR variability
Sinusoidal pattern --- correct answer ---visually apparent, smooth,
sine wave-like undulating pattern in fetal heart rate baseline with a
cycle frequency of 3-5 per minute which persists for 20 minutes or
more.
,Acceleration is defined as a visually apparent gradual increase in the
fetal heart rate above baseline.
Select Your Answer:
True
False --- correct answer ---False
Acceleration --- correct answer ---visually apparent abrupt increase
(defined as onset of acceleration to peak in < 30 seconds) in the fetal
heart rate above the baseline.
Abrupt acceleration --- correct answer ---Onset to peak < 30 seconds
Gradual acceleration --- correct answer ---Onset to peak ≥ 30 seconds
Abrupt deceleration --- correct answer ---Onset to nadir < 30 seconds
Gradual Deceleration --- correct answer ---Onset to nadir ≥ 30
seconds
, At 32 weeks of gestation and beyond, a fetal heart rate acceleration is
defined by a peak at least 20 beats per minute above the baseline and
a duration of at least 20 seconds.
Select Your Answer:
True
False --- correct answer ---False
At 32 weeks of gestation and beyond, an acceleration has a peak of 15
beats per minute or more above the baseline, with a duration of 15
seconds or more, but less than 2 minutes from onset to return.
Prolonged acceleration --- correct answer ---An acceleration that lasts
2 minutes or more, but less than 10 minutes
Baseline change --- correct answer ---an acceleration lasts 10 minutes
or longer
Before 32 weeks of gestation, an acceleration is defined as an abrupt
increase in the fetal heart rate at least 10 beats per minute above
baseline lasting at least 10 seconds.
