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