NU 333 exam 2 with correct answers
|\ |\ |\ |\ |\ |\




Varibality - CORRECT ANSWERS ✔✔irregular waves or fluctuations
|\ |\ |\ |\ |\ |\ |\


in baseline FHR. does not include accelerations/decelerations.
|\ |\ |\ |\ |\ |\ |\ |\


quantified in bpm. measured from peak to trough
|\ |\ |\ |\ |\ |\ |\




absent variability - CORRECT ANSWERS ✔✔Amplitude range of
|\ |\ |\ |\ |\ |\ |\ |\


the FHR fluctuations not detectable to the unaided eye.
|\ |\ |\ |\ |\ |\ |\ |\




minimal variability - CORRECT ANSWERS ✔✔Amplitude range less
|\ |\ |\ |\ |\ |\ |\


than or equal to 5 bpm
|\ |\ |\ |\ |\ |\




moderate variability - CORRECT ANSWERS ✔✔amplitude range 6-
|\ |\ |\ |\ |\ |\ |\


25 bpm|\




marked variability - CORRECT ANSWERS ✔✔amplitude range
|\ |\ |\ |\ |\ |\ |\


greater than 25 bpm |\ |\ |\




Sinusodial Pattern - CORRECT ANSWERS ✔✔wavelike pattern,
|\ |\ |\ |\ |\ |\ |\


uncommon but occurs with severe fetal anemia |\ |\ |\ |\ |\ |\




clinical significance of fetal bradycardia - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\


✔✔depends on the underlying cause and the accompanying FHR |\ |\ |\ |\ |\ |\ |\ |\ |\


patterns, including variability, accelerations or decelerations
|\ |\ |\ |\ |\

, clinical significance of fetal tachycardia - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\


✔✔only abnormal when associated with late decelerations,
|\ |\ |\ |\ |\ |\ |\


severe variable decelerations or absent variability
|\ |\ |\ |\ |\




Periodic changes in FHR - CORRECT ANSWERS ✔✔Associated with
|\ |\ |\ |\ |\ |\ |\ |\


uterine contractions
|\ |\




episodic changes in FHR - CORRECT ANSWERS ✔✔not associated
|\ |\ |\ |\ |\ |\ |\ |\ |\


with uterine contractions
|\ |\




accelerations - CORRECT ANSWERS ✔✔Periodic increases in the
|\ |\ |\ |\ |\ |\ |\ |\


baseline fetal heart rate |\ |\ |\




clinical significance of accelerations - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\


✔✔normal pattern; signifies fetal well-being
|\ |\ |\ |\




decelerations - CORRECT ANSWERS ✔✔periodic decrease in the
|\ |\ |\ |\ |\ |\ |\ |\


baseline fetal heart rate |\ |\ |\




can be early, late, variable, prolonged
|\ |\ |\ |\ |\




early decelerations - CORRECT ANSWERS ✔✔*safe* Begin prior to
|\ |\ |\ |\ |\ |\ |\ |\


peak of the contraction and end by the end of it. they are
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


caused by HEAD COMPRESSION. no need for intervention if
|\ |\ |\ |\ |\ |\ |\ |\ |\


variability is within normal range (6-10) and the FHR is within
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


normal range. |\
