Actual Exam 160 Questions and Correct Detailed
Answers Already Graded A+
Which of the following is an extrinsic influence on the FHR? - answer-C. Fetal-placental circulation
The most highly oxygenated blood in fetal circulation is carried by: - answer-C. Ductus venosus
If fetal arterial pressure begins to fall below normal levels: - answer-A. Baroreceptors cause
vasoconstriction and increase the FHR
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
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
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
