Following birth, a fetal cord blood sample is taken. The results are:
pH: 6.95
pCO2: 86 mmHg
pO2: 4mmHg
BE: -18.6 mEq/L
These results are best interpreted as: - ANSWER-C. Mixed acidemia
A characteristic of variable decelerations is: - ANSWER-B. The onset of the deceleration is abrupt
Stimulation of the vagus nerve in a healthy fetus will cause: - ANSWER-A. A decrease in the fetal
heart rate
What is the baseline rate? - ANSWER-B. 145 bpm
What is the correct interpretation? - ANSWER-B. Baseline of 160 bpm with recurrent late
decelerations
What is the primary physiologic goal? - ANSWER-B. Maximize oxygenation
,Based on the tracing, the most appropriate interventions are: - ANSWER-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? - ANSWER-C. The tracing of
uterine activity requires palpation for accurate assessment
The nurse supports maternal coping to appropriately assist Robin because - ANSWER-A. Reducing
maternal catecholamine production enhances blood flow to the uterus
Describe the type of variability seen in the majority of the tracing. - ANSWER-C. Absent
Fetal heart rate variability is defined as fluctuations in the baseline that are irregular in _____ and
_____. - ANSWER-B. Amplitude and frequency
An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: -
ANSWER-A. Occlusion of the umbilical vein
When assessing a FHR tracing, the first step is to: - ANSWER-C. Establish the baseline rate
Which deceleration in the FHR is considered benign and does not require an intervention to correct?
- ANSWER-A. Early deceleration
If the umbilical vein is the only vessel occluded during cord compression - ANSWER-B. Oxygenated
blood may be restricted from being delivered to the fetus
During a fetal sleep cycle, FHR variability is usually ____. - ANSWER-C. Minimal
Uterine tachysystole is defined as: - ANSWER-B. >5 contractions in 10 mind over 30 minutes
Maternal-fetal oxygen and nutrient transfer takes place in the: - ANSWER-B. intervillous space
,During a contraction, the tocodynamometer detects: - ANSWER-A. Pressure created by tensing of
uterine muscle
Normal fetal heart rate baseline is: - ANSWER-C. 110-160 bpm
Identify appropriate interventions to implement based on this tracing. - ANSWER-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? -
ANSWER-B. Placental abruption
What is the physiologic goal of top priority for Robin? - ANSWER-A. Maximize oxygenation
What bedside interventions are important at this time? - ANSWER-C. Notify provider of vaginal
bleeding, EFM tracing, and request presence at the bedside.
If the nurse does not get the appropriate response from the provider, the next step is - ANSWER-B.
Activate the chain of communication (command)
What is the correct interpretation of the tracing? - ANSWER-A. Sinusoidal pattern
The tracing in question 29 is which category? - ANSWER-C. Category III
Robin has a cesarean birth, Umbilical arterial cord blood gas results are as follows:
pH: 6.86
pCO2: 48
pO2: 4.2
BE: -23.7
These results meet the criteria for: - ANSWER-B. Metabolic acidemia
, What is the baseline rate? - ANSWER-B. 135 bpm
What type of variability is observed? - ANSWER-C. Moderate
What do you observe in the tracing that rules out metabolic acidemia at this time? - ANSWER-A:
15x15 accelerations
What pattern is observed in the fetal heart tracing? - ANSWER-A. Late decelerations
What extrinsic factor can you identify as a possible cause for the observed pattern? - ANSWER-C.
Aging placenta
What physiologic goals are priorities for Olivia's care? - ANSWER-B. Maximize oxygenation and
maintain appropriate uterine activity
What bedside interventions are appropriate for Olivia at this time? - ANSWER-C. Position change
to a lateral position and initiate a 500-mL IVFB.
What could Olivia's nurse do during second stage of labor to promote oxygenation? - ANSWER-B.
Encourage Olivia to push with every other contraction
Did the fetal monitor tracing prior to delivery accurately predict the cor - ANSWER-A> Yes, the
presence of moderate variability rules out the metabolic acidemia.
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
