AWHONN Intermediate Fetal Monitoring TEST (Answered 100% Correctly) Updated 2024-2025 Which of the following is an extrinsic influence on the FHR? C. Fetal-placental circulation The most highly oxygenated blood in fetal circulation is carried by: C. Ductus venosus If fetal arterial pressure begins to fall below normal levels: A. Baroreceptors cause vasoconstriction and increase the FHR Fetal heart rate variability is defined as fluctuations in the baseline that are irregular in _____ and _____. B. Amplitude and frequency An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: A. Occlusion of the umbilical vein When assessing a FHR tracing, the first step is to: C. Establish the baseline rate Which deceleration in the FHR is considered benign and does not require an intervention to correct? A. Early deceleration If the umbilical vein is the only vessel occluded during cord compression B. Oxygenated blood may be restricted from being delivered to the fetus During a fetal sleep cycle, FHR variability is usually ____. C. Minimal Uterine tachysystole is defined as: B. >5 contractions in 10 mind over 30 minutes Maternal-fetal oxygen and nutrient transfer takes place in the: B. intervillous space During a contraction, the tocodynamometer detects: A. Pressure created by tensing of uterine muscle Normal fetal heart rate baseline is: 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: C. Mixed acidemia A characteristic of variable decelerations is: BE: -23.7 These results meet the criteria for: B. Metabolic acidemia What is the baseline rate? B. 135 bpm What type of variability is observed? C. Moderate What do you observe in the tracing that rules out metabolic acidemia at this time? A: 15x15 accelerations What pattern is observed in the fetal heart tracing? A. Late decelerations What extrinsic factor can you identify as a possible cause for the observed pattern? C. Aging placenta What physiologic goals are priorities for Olivia's care? B. Maximize oxygenation and maintain appropriate uterine activity What bedside interventions are appropriate for Olivia at this time? 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? B. Encourage Olivia to push with every other contraction Did the fetal monitor tracing prior to delivery accurately predict the cor A> Yes, the presence of moderate variability rules out the metabolic acidemia. What is the baseline FHR? B. 160 bpm What type of variability is observed? A. Moderate What interventions are appropriate at this time? C. Reposition Shelby from left lateral to right lateral What type of pattern is observed in the tracing? B. Variable decelerations What category is this tracing? B. Category II What is the baseline rate? C. Unable to determine Based on your observation of the tracing, what action(s) is (are) required? B. Palpate Shelby's radial pulse to verify maternal vs. fetal heart rate Which statement most accurately reflects the EFM tracing? A. Maternal and fetal heart rates should be verified Which pattern in the fetal heart rate would increase suspicion of a nuchal cord? C. Variable decelerations Shelby delivers a male infant with Apgar scores of 2 and 3. Umbilical arterial cord blood gases show: pH: 6.92 pCO2: 79 pO2: 11 BE: -7.6 What is the correct interpretation of the cod blood gas? A. Respiratory acidemia
