AWHONN Intermediate Fetal Monitoring TEST Questions and Answers(A+ Solution guide)

Which of the following is an extrinsic influence on the FHR? - ✔✔ C. Fetal -placental c irculation 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 variab ility 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: - ✔✔ B. The onset of the deceleration is abrupt Stimulation of the vagus nerve in a healthy fetus will cause: - ✔✔ A. A decrease in the fetal heart rate What is the baseline rate? - ✔✔ B. 145 bpm What is the c orrect interpretation? - ✔✔ B. Baseline of 160 bpm with recurrent late decelerations What is the primary physiologic goal? - ✔✔ B. Maximize oxygenation Based on the tracing, the most appropriate interventions are: - ✔✔ B. Decrease oxytocin from 14 to 7 mU/m in and start a 500 -mL IVFB. Which of the following is a correct interpretation of the tracing? - ✔✔ C. The tracing of uterine activity requires palpation for accurate assessment
