ACTUAL EXAM QUESTIONS AND CORRECT DETAILED
ANSWERS WITH RATIONALES (VERIFIED ANSWERS)
Which of the following is an extrinsic influence on the FHR? -CORRECT->>C. Fetal-
placental circulation
The most highly oxygenated blood in fetal circulation is carried by: -CORRECT->>C.
Ductus venosus
If fetal arterial pressure begins to fall below normal levels: -CORRECT->>A.
Baroreceptors cause vasoconstriction and increase the FHR
Fetal heart rate variability is defined as fluctuations in the baseline that are irregular in
and . -CORRECT->>B. Amplitude and frequency
An increase in the fetal heart rate immediately preceding a variable deceleration is
caused by: -CORRECT->>A. Occlusion of the umbilical vein
When assessing a FHR tracing, the first step is to: -CORRECT->>C. Establish the
baseline rate
Which deceleration in the FHR is considered benign and does not require an
intervention to correct? -CORRECT->>A. Early deceleration
If the umbilical vein is the only vessel occluded during cord compression -CORRECT-
>>B. Oxygenated blood may be restricted from being delivered to the fetus
During a fetal sleep cycle, FHR variability is usually . -CORRECT->>C. Minimal
Uterine tachysystole is defined as: -CORRECT->>B. >5 contractions in 10 mind over 30
minutes
Maternal-fetal oxygen and nutrient transfer takes place in the: -CORRECT->>B.
intervillous space
During a contraction, the tocodynamometer detects: -CORRECT->>A. Pressure created
by tensing of uterine muscle
Normal fetal heart rate baseline is: -CORRECT->>C. 110-160 bpm
Following birth, a fetal cord blood sample is taken. The results are:
pH: 6.95

These results are best interpreted as: -CORRECT->>C. Mixed acidemia
, A characteristic of variable decelerations is: -CORRECT->>B. The onset of the
deceleration is abrupt

decrease in the fetal heart rate
What is the baseline rate? -CORRECT->>B. 145 bpm
What is the correct interpretation? -CORRECT->>B. Baseline of 160 bpm with recurrent
late decelerations
What is the primary physiologic goal? -CORRECT->>B. Maximize oxygenation
Based on the tracing, the most appropriate interventions are: -CORRECT->>B.
Decrease oxytocin from 14 to 7 mU/min and start a 500-mL IVFB.
Which of the following is a correct interpretation of the tracing? -CORRECT->>C. The
tracing of uterine activity requires palpation for accurate assessment
The nurse supports maternal coping to appropriately assist Robin because -CORRECT-
>>A. Reducing maternal catecholamine production enhances blood flow to the uterus
Describe the type of variability seen in the majority of the tracing. -CORRECT->>C.
Absent
Identify appropriate interventions to implement based on this tracing. -CORRECT->>B.
Palpate uterus, adjust toco, assist patient to lateral position.
What does the EFM tracing above and the observed patient assessment raise your
suspicion of? -CORRECT->>B. Placental abruption

oxygenation
What bedside interventions are important at this time? -CORRECT->>C. Notify provider
of vaginal bleeding, EFM tracing, and request presence at the bedside.
