AWHONN Advanced Fetal Monitoring Exam 2025/2026
Questions with 100% Detailed Answers.
What does the Tocodynamometer measure? - ANSWER-
Contractions by detecting abdominal wall contour
changes. The device converts this to electronic impulses
that register and print out on paper.
Toco does NOT quantify resting tone or intensity of
contractions. Changes of the abd wall can be caused by a
number of events besides contractions (mat. respirations,
pushing, vomiting, seizures, fetal activity and movement).
A normal contraction creates a smooth and even fall on
the tracing
Identify the uterine contraction variation: - ANSWER-a.
Uterine contraction wave form normal
,2|Page
b. Maternal respiration
c. Valsalva maneuver or pushing
d. Maternal activity such as vomiting or seizure
e. Fetal movement/activity
f. Maternal position change or sudden baseline shift
g. Obscured or low baseline setting
h. Inverted waveform r/t placement of toco
Identify the uterine contraction variation: - ANSWER-a.
Uterine contraction wave form normal
b. Maternal respiration

e. Fetal movement/activity
f. Maternal position change or sudden baseline shift
g. Obscured or low baseline setting
h. Inverted waveform r/t placement of toco
Explain absent FHR variability. - ANSWER-undetectable
amplitude range
can be indicative of impending fetal hypoxia
Explain minimal variability. - ANSWER-amplitude
>undetectable (visually detectable but less than or equal
to 5 BPM)
can be indicative of impending fetal hypoxia
, 4|Page
Explain moderate variability. - ANSWER-amplitude range
6-25 BPM
Explain marked variability. - ANSWER-amplitude range
>25 BPM
What does it mean to have an undulating FHR pattern?
What are the causes of undulating patterns in FHR? -
ANSWER-A compromised fetus.
possible causes are severe fetal anemia from RH
isoimmunization, massive feto-maternal hemorrhage,
ruptured vasa previa, twin to twin transfusion, fetal
intracranial hemorrhage.
