TEST

Which of the following is an extrinsic influence on the FHR? - correct answer C. Fetal-placental circulation The most highly oxygenated blood in fetal circulation is carried by: - correct answer C. Ductus venosus If fetal arterial pressure begins to fall below normal levels: - correct 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 _____. - correct answer B. Amplitude and frequency An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: - correct answer A. Occlusion of the umbilical vein When assessing a FHR tracing, the first step is to: - correct answer C. Establish the baseline rate Which deceleration in the FHR is considered benign and does not require an intervention to correct? - correct answer A. Early deceleration If the umbilical vein is the only vessel occluded during cord compression - correct answer B. Oxygenated blood may be restricted from being delivered to the fetus During a fetal sleep cycle, FHR variability is usually ____. - correct answer C. Minimal Uterine tachysystole is defined as: - correct answer B. >5 contractions in 10 mind over 30 minutes

Maternal-fetal oxygen and nutrient transfer takes place in the: - correct answer B. intervillous space During a contraction, the tocodynamometer detects: - correct answer A. Pressure created by tensing of uterine muscle Normal fetal heart rate baseline is: - correct answer 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: - correct answer C. Mixed acidemia A characteristic of variable decelerations is: - correct answer B. The onset of the deceleration is abrupt Stimulation of the vagus nerve in a healthy fetus will cause: - correct answer A. A decrease in the fetal heart rate What is the baseline rate? - correct answer B. 145 bpm What is the correct interpretation? - correct answer B. Baseline of 160 bpm with recurrent late decelerations What is the primary physiologic goal? - correct answer B. Maximize oxygenation Based on the tracing, the most appropriate interventions are: - correct 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? - correct answer C. The tracing of uterine activity requires palpation for accurate assessment The nurse supports maternal coping to appropriately assist Robin because - correct answer A. Reducing maternal catecholamine production enhances blood flow to the uterus Describe the type of variability seen in the majority of the tracing. - correct answer C. Absent Identify appropriate interventions to implement based on this tracing. - correct 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? - correct answer B. Placental abruption What is the physiologic goal of top priority for Robin? - correct answer A. Maximize oxygenation What bedside interventions are important at this time? - correct 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 - correct answer B. Activate the chain of communication (command) What is the correct interpretation of the tracing? - correct answer A. Sinusoidal pattern The tracing in question 29 is which category? - correct answer 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: - correct answer B. Metabolic acidemia What is the baseline rate? - correct answer B. 135 bpm What type of variability is observed? - correct answer C. Moderate What do you observe in the tracing that rules out metabolic acidemia at this time? - correct answer A: 15x15 accelerations What pattern is observed in the fetal heart tracing? - correct answer A. Late decelerations What extrinsic factor can you identify as a possible cause for the observed pattern? - correct answer C. Aging placenta What physiologic goals are priorities for Olivia's care? - correct answer B. Maximize oxygenation and maintain appropriate uterine activity What bedside interventions are appropriate for Olivia at this time? - correct 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? - correct answer B. Encourage Olivia to push with every other contraction Did the fetal monitor tracing prior to delivery accurately predict the cor - correct answer A> Yes, the presence of moderate variability rules out the metabolic acidemia. What is the baseline FHR? - correct answer B. 160 bpm What type of variability is observed? - correct answer A. Moderate

What interventions are appropriate at this time? - correct answer C. Reposition Shelby from left lateral to right lateral What type of pattern is observed in the tracing? - correct answer B. Variable decelerations What category is this tracing? - correct answer B. Category II What is the baseline rate? - correct answer C. Unable to determine Based on your observation of the tracing, what action(s) is (are) required? - correct answer B. Palpate Shelby's radial pulse to verify maternal vs. fetal heart rate Which statement most accurately reflects the EFM tracing? - correct answer A. Maternal and fetal heart rates should be verified Which pattern in the fetal heart rate would increase suspicion of a nuchal cord? - correct answer C. Variable decelerations Shelby delivers a male infant with Apgar scores of 2 and 3. Umbilical arterial cord blood gases show: pH: 6. pCO2: 79 pO2: 11 BE: -7. What is the correct interpretation of the cod blood gas? - correct answer A. Respiratory acidemia
