Which of the following is an extrinsic influence on the FHR? - ACCURATE ANSWERS✔✔ C. Fetal-placental circulation. The most highly oxygenated blood in fetal circulation is carried by: - ACCURATE ANSWERS✔✔ C. Ductus venosus. If fetal arterial pressure begins to fall below normal levels: - ACCURATE ANSWERS✔✔ A. Baroreceptors cause vasoconstriction and increase the FHR. Fetal heart rate variability is defined as fluctuations in the baseline that are irregular in _____ and _____. - ACCURATE ANSWERS✔✔ B. Amplitude and frequency An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: - ACCURATE ANSWERS✔✔ A. Occlusion of the umbilical vein When assessing a FHR tracing, the first step is to: - ACCURATE ANSWERS✔✔ C. Establish the baseline rate

Which deceleration in the FHR is considered benign and does not require an intervention to correct? - ACCURATE ANSWERS✔✔ A. Early deceleration If the umbilical vein is the only vessel occluded during cord compression - ACCURATE ANSWERS✔✔ B. Oxygenated blood may be restricted from being delivered to the fetus During a fetal sleep cycle, FHR variability is usually ____. - ACCURATE ANSWERS✔✔ C. Minimal Uterine tachysystole is defined as: - ACCURATE ANSWERS✔✔ B. > contractions in 10 mind over 30 minutes Maternal-fetal oxygen and nutrient transfer takes place in the: - ACCURATE ANSWERS✔✔ B. intervillous space During a contraction, the tocodynamometer detects: - ACCURATE ANSWERS✔✔ A. Pressure created by tensing of uterine muscle Normal fetal heart rate baseline is: - ACCURATE ANSWERS✔✔ C. 110-160 bpm Following birth, a fetal cord blood sample is taken. The results are: pH: 6. pCO2: 86 mmHg

pO2: 4mmHg BE: -18.6 mEq/L These results are best interpreted as: - ACCURATE ANSWERS✔✔ C. Mixed acidemia A characteristic of variable decelerations is: - ACCURATE ANSWERS✔✔ B. The onset of the deceleration is abrupt Stimulation of the vagus nerve in a healthy fetus will cause: - ACCURATE ANSWERS✔✔ A. A decrease in the fetal heart rate What is the baseline rate? - ACCURATE ANSWERS✔✔ B. 145 bpm What is the correct interpretation? - ACCURATE ANSWERS✔✔ B. Baseline of 160 bpm with recurrent late decelerations What is the primary physiologic goal? - ACCURATE ANSWERS✔✔ B. Maximize oxygenation Based on the tracing, the most appropriate interventions are: - ACCURATE ANSWERS✔✔ 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? - ACCURATE ANSWERS✔✔ C. The tracing of uterine activity requires palpation for accurate assessment

The nurse supports maternal coping to appropriately assist Robin because - ACCURATE ANSWERS✔✔ A. Reducing maternal catecholamine production enhances blood flow to the uterus Describe the type of variability seen in the majority of the tracing. - ACCURATE ANSWERS✔✔ C. Absent Identify appropriate interventions to implement based on this tracing. - ACCURATE ANSWERS✔✔ 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? - ACCURATE ANSWERS✔✔ B. Placental abruption What is the physiologic goal of top priority for Robin? - ACCURATE ANSWERS✔✔ A. Maximize oxygenation What bedside interventions are important at this time? - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ B. Activate the chain of communication (command)

What is the correct interpretation of the tracing? - ACCURATE ANSWERS✔✔ A. Sinusoidal pattern The tracing in question 29 is which category? - ACCURATE ANSWERS✔✔ C. Category III Robin has a cesarean birth, Umbilical arterial cord blood gas results are as follows: pH: 6. pCO2: 48 pO2: 4. BE: -23. These results meet the criteria for: - ACCURATE ANSWERS✔✔ B. Metabolic acidemia What is the baseline rate? - ACCURATE ANSWERS✔✔ B. 135 bpm What type of variability is observed? - ACCURATE ANSWERS✔✔ C. Moderate What do you observe in the tracing that rules out metabolic acidemia at this time? - ACCURATE ANSWERS✔✔ A: 15x15 accelerations

What pattern is observed in the fetal heart tracing? - ACCURATE ANSWERS✔✔ A. Late decelerations What extrinsic factor can you identify as a possible cause for the observed pattern? - ACCURATE ANSWERS✔✔ C. Aging placenta What physiologic goals are priorities for Olivia's care? - ACCURATE ANSWERS✔✔ B. Maximize oxygenation and maintain appropriate uterine activity What bedside interventions are appropriate for Olivia at this time? - ACCURATE ANSWERS✔✔ 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? - ACCURATE ANSWERS✔✔ B. Encourage Olivia to push with every other contraction Did the fetal monitor tracing prior to delivery accurately predict the cor - ACCURATE ANSWERS✔✔ A> Yes, the presence of moderate variability rules out the metabolic acidemia. What is the baseline FHR? - ACCURATE ANSWERS✔✔ B. 160 bpm What type of variability is observed? - ACCURATE ANSWERS✔✔ A. Moderate

What interventions are appropriate at this time? - ACCURATE ANSWERS✔✔ C. Reposition Shelby from left lateral to right lateral What type of pattern is observed in the tracing? - ACCURATE ANSWERS✔✔ B. Variable decelerations What category is this tracing? - ACCURATE ANSWERS✔✔ B. Category II What is the baseline rate? - ACCURATE ANSWERS✔✔ C. Unable to determine Based on your observation of the tracing, what action(s) is (are) required? - ACCURATE ANSWERS✔✔ B. Palpate Shelby's radial pulse to verify maternal vs. fetal heart rate Which statement most accurately reflects the EFM tracing? - ACCURATE ANSWERS✔✔ A. Maternal and fetal heart rates should be verified Which pattern in the fetal heart rate would increase suspicion of a nuchal cord? - ACCURATE ANSWERS✔✔ C. Variable decelerations Shelby delivers a male infant with Apgar scores of 2 and 3. Umbilical arterial cord blood gases show:
