Updated AWHONN Intermediate Fetal Monitoring TEST Questions and Answers (A+ Solution guide) Which of the following is an extrinsic influence on the FHR? - ANSWER>>>C. Fetal-placental circulation The most highly oxygenated blood in fetal circulation is carried by: - ANSWER>>>C. Ductus venosus If fetal arterial pressure begins to fall below normal levels: - 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 _____. - ANSWER>>>B. Amplitude and frequency An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: - ANSWER>>>A. Occlusion of the umbilical vein When assessing a FHR tracing, the first step is to: - ANSWER>>>C. Establish the baseline rate Which deceleration in the FHR is considered benign and does not require an intervention to correct? - ANSWER>>>A. Early deceleration If the umbilical vein is the only vessel occluded during cord compression - ANSWER>>>B. Oxygenated blood may be restricted from being delivered to the fetus During a fetal sleep cycle, FHR variability is usually ____. - ANSWER>>>C. Minimal Uterine tachysystole is defined as: - ANSWER>>>B. >5 contractions in 10 mind over 30 minutes Maternal-fetal oxygen and nutrient transfer takes place in the: - ANSWER>>>B. intervillous space During a contraction, the tocodynamometer detects: - ANSWER>>>A. Pressure created by tensing of uterine muscle Normal fetal heart rate baseline is: - ANSWER>>>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: - ANSWER>>>C. Mixed acidemia A characteristic of variable decelerations is: - ANSWER>>>B. The onset of the deceleration is abrupt Stimulation of the vagus nerve in a healthy fetus will cause: - ANSWER>>>A. A decrease in the fetal heart rate What is the baseline rate? - ANSWER>>>B. 145 bpm What is the correct interpretation? - ANSWER>>>B. Baseline of 160 bpm with recurrent late decelerations What is the primary physiologic goal? - ANSWER>>>B. Maximize oxygenation Based on the tracing, the most appropriate interventions are: - 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? - ANSWER>>>C. The tracing of uterine activity requires palpation for accurate assessment The nurse supports maternal coping to appropriately assist Robin because - ANSWER>>>A. Reducing maternal catecholamine production enhances blood flow to the uterus Describe the type of variability seen in the majority of the tracing. - ANSWER>>>C. Absent Identify appropriate interventions to implement based on this tracing. - 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? - ANSWER>>>B. Placental abruption What is the physiologic goal of top priority for Robin? - ANSWER>>>A. Maximize oxygenation What bedside interventions are important at this time? - 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 - ANSWER>>>B. Activate the chain of communication (command) What is the correct interpretation of the tracing? - ANSWER>>>A. Sinusoidal pattern The tracing in question 29 is which category? - ANSWER>>>C. Category III Robin has a cesarean birth, Umbilical arterial cord blood gas results are as follows: pH: 6.86 pCO2: 48 pO2: 4.2 BE: -23.7 These results meet the criteria for: - ANSWER>>>B. Metabolic acidemia What is the baseline rate? - ANSWER>>>B. 135 bpm What type of variability is observed? - ANSWER>>>C. Moderate
