2025/2026 EXAM 100 QUESTIONS AND CORRECT DETAILED ANSWERS
WITH RATIONALES (VERIFIED ANSWERS) |ALREADY GRADED A+
What is the baseline FHR? - ......ANSWER........B. 160 bpm
What type of variability is observed? - ......ANSWER........A. Moderate
What interventions are appropriate at this time? - ......ANSWER........C. Reposition Shelby
from left lateral to right lateral
What type of pattern is observed in tracing? - ......ANSWER........B. Variable decelerations
What category is this tracing? - ......ANSWER........B. Category II
What is the baseline rate? - ......ANSWER........C. Unable to determine
Based on your observation of tracing, what action(s) is required? - ......ANSWER........B.
Palpate Shelby's radial pulse to verify maternal vs. fetal heart rate
Which statement most accurately reflects the EFM tracing? - ......ANSWER........A.
Maternal and fetal heart rates should be verified
Which pattern in the fetal heart rate would increase suspicion of a nuchal cord?
- ......ANSWER........C. Variable decelerations
Shelby delivers a male infant with Apgar scores of 2 and 3. Umbilical arterial cord blood
gases show: pH: 6.92 pCO2: 79 pO2: 11 BE: -7.6 What is the correct interpretation of the
cold blood gas? - ......ANSWER........A. Respiratory acidemia
If fetal arterial pressure begins to fall below normal levels: - ......ANSWER........A.
BARORECEPTORS CAUSE VASOCONSTRICTION AND INCREASE THE FHR
, 2 of 8
An increase in arterial blood pressure produces vessel distension and causes arterial
baroreceptors to send neuronal messages to the cardioinhibitory center, which in turn
causes rapid slowing of the fetal heart rate via the parasympathetic vagus nerve. A
decrease in arterial pressure results in an increased heart rate.

Which of the following is an extrinsic influence on the FHR? - ......ANSWER........Fetal-
placental circulation
Fetal heart rate variability is definded as fluctuations in the baseline that are irregular in
- ......ANSWER........AMPLITUDE and FREQUENCY
The most highly oxygenated blood in fetal circulation is carried by:
- ......ANSWER........Ductus venosus
An increase in the fetal heart rate immediately preceding a variable deceleration is caused
by: - ......ANSWER........Occlusion of the umbilical vein
The etiology of variable decelerations is likely related to umbilical venous and arterial
occlusion. Initially, with occlusion of the thin-walled umbilical vein, venous return to the
fetal right atrium is reduced, producing a reflex of tachycardia. This pattern often is
observed as a shoulder on the FHR monitor strip immediately before the abrupt variable
FHR deceleration
