fetal heart tracing quiz 10

140 145 150 155 160 2. Accelerations represent a sudden increase in FHR of more than 15 bpm in bandwidth amplitude. The nurse's action after turning the patient to her left side should be:, The nurse is assessing a fetal monitor tracing and notes that the FHR baseline is 140-150 bpm with decreases to 120 bpm noted beginning . A prolonged fetal heart rate deceleration lasts >2 minutes, but <10 minutes. The normal FHR range is between 120 and 160 beats per minute (bpm). -Neither period yields adequate accelerations Tachycardia greater than 200 bpm is usually due to fetal tachyarrhythmia (Figure 4) or congenital anomalies rather than hypoxia alone.16 Causes of fetal tachycardia are listed in Table 5. Increased variability in the baseline FHR is present when the oscillations exceed 25 bpm (Figure 2). 7. Intrapartum category I, II, and III fetal heart rate tracings The FHR baseline is 120-130 bpm. The resulting printout is known as a fetal heart tracing, which will be read and analyzed. A scalp pH of less than 7.20 is considered abnormal and generally is an indication for intervention, immediate delivery, or both.12 A pH less than 7.20 should also be assumed in the absence of an acceleration following fetal scalp stimulation when fetal scalp pH sampling is not available. Fetal monitoring Flashcards | Quizlet The clinical risk status (low, medium, or high) of each fetus is assessed in conjunction with the interpretation of the continuous EFM tracing. fetal heart tracing quiz 12 - islamichouseofisrael.com A nurse notes the following fetal heart rate pattern on the external fetal monitor. The EFM toolkit also offers EFM CE opportunities and C-EFM(R) certification information. Practice basic fetal tracing analysis with some quizzes: Quizzes 1-5. Health care professionals play the game to hone and test their EFM knowledge and skills. Structured intermittent auscultation detects changes in FHR during contractions but not overall FHR variability (moment-by-moment fluctuations in FHR)4,5; therefore, continuous electronic fetal monitoring remains the more appropriate option in high-risk labor (Table 214,16,17). [7] The fetal heart rate tracing categorizes into I, II, or III depending upon the criteria as mentioned above. Every 15 to 30 minutes in active phase of first stage of labor; every 5 minutes in second stage of labor with pushing, Assess FHR before: initiation of labor-enhancing procedure; ambulation of patient; administration of medications; or initiation of analgesia or anesthesia, Assess FHR after: admission of patient; artificial or spontaneous rupture of membranes; vaginal examination; abnormal uterine activity; or evaluation of analgesia or anesthesia, 1. 4. Health care professionals play the game to hone and test their EFM knowledge and skills. NCC EFM Tracing Game. -Try to get 3 uterine contractions within 10-minute period, -Absolute: Placenta Previa, Cerclage, Incompetent cervix Presence of moderate fetal heart rate variability and accelerations with absence of recurrent pathologic decelerations provides reassurance that acidosis is not present. Electronic fetal monitoring is performed in a hospital or doctors office. A change in baseline FHR is said to occur when the change persists for 10 minutes or longer. The most important risk of EFM is its tendency to produce false-positive results. After discussion regarding the FHR tracing, the resident and attending practitioner on duty determine that the FHR tracing is a Category II. Fetal scalp sampling for pH is recommended if there is no acceleration with scalp stimulation.11. Assessments. Fetal Heart Tracing Quiz 8 - Utilis . Differentiating between a reassuring and nonreassuring fetal heart rate pattern is the essence of accurate interpretation, which is essential to guide appropriate triage decisions. Correlate accelerations and decelerations with uterine contractions and identify the pattern. Document in detail interpretation of FHR, clinical conclusion and plan of management. the presence of moderate variability and/or accelerations offers reassurance in Category II tracings because the presence is predictive of a lack of fetal acidosis, Category II management should focus on first correcting reversible causes, including stopping uterotonic agents and placental fetal perfusion, through intrauterine resuscitation, Amnioinfusion has been shown to reduce cord compression, leading to resolution of FHR decelerations (RR = 0.53; 95% CI, 0.38 to 0.74; n = 1,000) and lowering the likelihood of cesarean delivery. Non-reactive: 4 It is. If the cause cannot be identified and corrected, immediate delivery is recommended. EFM In-Depth. structured intermittent auscultation should be considered for low-risk labor because it statistically decreases cesarean and operative vaginal delivery rates without an increase in unfavorable outcomes associated with continuous monitor use and a high false-positive rate. Intrapartum Fetal Heart Rate Monitoring - Perinatology.com Early decelerations are caused by fetal head compression during uterine contraction, resulting in vagal stimulation and slowing of the heart rate. When continuous EFM tracing is indeterminate, fetal scalp pH sampling or fetal stimulation may be used to assess for the possible presence of fetal acidemia.5 Fetal scalp pH testing is no longer commonly performed in the United States and has been replaced with fetal stimulation or immediate delivery (by operative vaginal delivery or cesarean delivery). Influence of Gestational Age on Fetal Heart Rate 8. It involves using an electronic fetal monitor that records the fetal heart rate and the frequency and duration of uterine contractions. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. The nurse understands that the primary intervention is to: The nurse notes that the fetal heart rate baseline is 120-130 with an increase in FHR to 145 bpm lasting 15 seconds. Continuous EFM reduced neonatal seizures (NNT = 661), but not the occurrence of cerebral palsy. About. Practice Quizzes 1-5 - Electronic Fetal Monitoring The fetal heart rate undergoes constant and minute adjustments in response to the fetal environment and stimuli. The FHR is controlled by the autonomic nervous system. You scored 6 out of 6 correct. The transducer uses Doppler ultrasound to detect fetal heart motion and is connected to an FHR monitor. A student nurse is placing a tocotransducer on a woman for electronic fetal monitoring. What should the incoming nurse do FIRST? Theyll wrap a pair of belts around your belly. A pattern of persistent late decelerations is nonreassuring, and further evaluation of the fetal pH is indicated.16 Persistent late decelerations associated with decreased beat-to-beat variability is an ominous pattern19 (Figure 7). Fetal Heart Tracing Quiz 1 - utilis.net Intermountain Healthcare - Interprofessional Continuing Education, Third Annual Advanced Fetal Heart Rate Interpretation Conference, 10/27/2023 12:00:00 PM - 10/27/2023 5:00:00 PM, This conference will discuss fetal heart rate variability including: pathophysiology of variability; extreme abnormalities of variability; variability in the Category II Fetal Heart Tracing Algorithm; and case . The patient's labor has been normal to this point. Accelerations last from 15 seconds to 10 minutes, and the majority occur in conjunction with fetal movements. Decreased variability is defined as a variation of one to five bpm from baseline for at least 10 minutes5 (eFigure D). Depending on your health status and your babys, nonstress tests (one to two times a week, if not daily) might be a good idea. Management depends on the clinical picture and presence of other FHR characteristics.18, Overall Assessment (O). D. Determine the onset and end of each deceleration in relation to the onset and end of the contraction. PDF Awhonn Fetal Monitoring Test Questions And Answers Pdf Copy 2023 National Certification Corporation. selected each time a collection is played. No. Patient Safety, Risk Management, and Documentation 11. DR C BRAVADO (determine risk, contractions, baseline rate, variability, accelerations, decelerations, overall assessment) is a mnemonic that serves as a standardized tracing interpretation and reporting tool14 (Table 44,5,7,14,16,26). Questions and Answers 1. -Accelerations my be present or absent. Nonreassuring variable decelerations associated with the loss of beat-to-beat variability correlate substantially with fetal acidosis4 and therefore represent an ominous pattern. Electronic fetal heart rate monitoring (EFM) was first introduced at Yale University in 1958.1 Since then, continuous EFM has been widely used in the detection of fetal compromise and the assessment of the influence of the intrauterine environment on fetal welfare. We also searched the Cochrane Library, Essential Evidence Plus, and Clinical Evidence. A. Table 4 lists recommended emergency interventions for nonreassuring patterns.4,14 These interventions should also be considered for ominous patterns while preparations for immediate delivery are initiated. A systematic approach is recommended when reading FHR recordings to avoid misinterpretation (Table 2). Decompression melting as the mantle rises, C. Melting of continental crust caused by an influx of mantle-derived magmas. Almost any stressful situation in the fetus evokes the baroreceptor reflex, which elicits selective peripheral vasoconstriction and hypertension with a resultant bradycardia. -Fetal breathing movements This variability reflects a healthy nervous system, chemoreceptors, baroreceptors and cardiac responsiveness. Uterine tachysystole is defined as more than five contractions in any 10-minute period, averaged over 30 minutes.2 Each normal uterine contraction causes a temporary decrease in uterine blood flow and fetal oxygenation, which is generally well tolerated.26,27 However, tachysystole increases the risk of acidosis.26,27 To correct tachysystole, physicians must reduce or stop uterine stimulants or add tocolytics.2,2729, Goals of intrapartum fetal monitoring include rapid identification and intervention for suspected fetal acidosis as well as reassurance and avoidance of unnecessary interventions in cases of adequate fetal oxygenation.4,26 Figure 1 provides an algorithm for suggested management.2,7,16,21,27,3033. -2 points for each normal, 0 for abnormal, -8-10: Normal result ,Repeat BPP weekly Multivariate logistic regression analyses were performed to control for confounding variables (SPSS). The practitioner has ordered continuous electronic monitoring, but the patient requests IA for the early part of labor. Late decelerations are associated with uteroplacental insufficiency and are provoked by uterine contractions. Sketch or describe how the https://www.ncbi.nlm.nih.gov/pubmed/19546798 3/10/2017 Fetal Heart Tracing Quiz 10 Correct. Yes, and the strip is reactive. May 2, 2022. Fetal Assessment in Non-Obstetric Settings 9. A more recent article on intrapartum fetal monitoring is available. Most patients who undergo internal fetal monitoring during labor accept monitoring as a positive experience.6. The FHR baseline is 130 bpm with moderate variability. EFM Tracing Game. Adequate documentation is necessary, and many institutions are now employing flow sheets (e.g., partograms), clinical pathways, or FHR tracing archival processes (in electronic records). Contractions are occurring every 3 minutes and lasting 60 seconds, and are of moderate intensity with a soft resting tone. What are the two most important characteristics of the FHR? The patient in labor is having multiple deep variable decelerations down to 60-70 bpm. 10. Which of the following information should be included? Suppose the 4040 \Omega40 resistance in the distribution circuit is replaced by a 2020 \Omega20 resistance. The nurse will chart the variability as which of the following? Copyright 1999 by the American Academy of Family Physicians. However, the strength of contractions cannot always be accurately assessed from an external transducer and should be determined with an IUPC, if necessary. If one of the following is detected during structured intermittent auscultation for a low-risk patient, switch to continuous electronic fetal monitoring to assess the National Institute of Child Health and Human Development category and to determine necessary clinical management: Fetal tachycardia (> 160 beats per minute for > 10 minutes), Fetal bradycardia (< 110 beats per minute for > 10 minutes), Recurrent decelerations following contractions (> 50% of contractions) or prolonged deceleration (> 2 minutes but < 10 minutes). A way to assess your babys overall health, fetal heart tracing is performed before and during the process of labor. The patient is now 7 cm dilated, 100% effaced, and at +1 station. Fetal scalp sampling, which requires amniotomy, tests fetal pH for the presence of acidemia.16 However, because of a 10% inadequate sample rate and a prolonged sample-to-result time of 18 minutes on average, this test is rarely performed in the United States.20 Lactate fetal scalp sampling (direct measurement of lactate by a probe) is another option that boasts a sample-to-result time of two minutes; however, its use has not resulted in improved newborn outcomes.21 An internal real-time fetal pulse oximetry probe (similar to an intrauterine pressure catheter) may lower operative vaginal delivery rates during the second stage of labor but has no apparent effect on neonatal outcomes.22,23 Fetal electrocardiograms have also been studied because fetal acidosis can affect the ST interval. Rate and decelerations B. Severe prolonged bradycardia of less than 80 bpm that lasts for three minutes or longer is an ominous finding indicating severe hypoxia and is often a terminal event.4,11,16 Causes of prolonged severe bradycardia are listed in Table 6. Hypoxia, uterine contractions, fetal head compression and perhaps fetal grunting or defecation result in a similar response. is part of the free online EFM toolkit at. T(t)=50+50cos(6t).T(t)=50+50 \cos \left(\frac{\pi}{6} t\right) . The baseline rate is interpreted as changed if the alteration persists for more than 15 minutes. Any written information on the tracing (e.g., emergent situations during labor) should coincide with these automated processes to minimize litigation risk.21, Table 5 lists intrauterine resuscitation interventions for abnormal EFM tracings.9 Management will depend on assessment of the risk of hypoxia and the ability to effect a rapid delivery, when necessary. Some clinicians have argued that this unproven technology has become the standard for all patients designated high risk and has been widely applied to low-risk patients as well.9 The worldwide acceptance of EFM reflects a confidence in the importance of electronic monitoring and concerns about the applicability of auscultation.10 However, in a 1996 report, the U.S. Preventive Services Task Force7 did not recommend the use of routine EFM in low-risk women in labor. Practice Quizzes 6-10 - Electronic Fetal Monitoring. Tachysystole in term labor: incidence, risk factors, outcomes, and effect on fetal heart tracings. Management includes further investigation into and correction of possible stressors.14,33, Variable decelerations are recurrent when they occur with greater than 50% of contractions in any 20-minute period2,5 (Figure 57). Fetal Heart Tracing Quiz 2 - 3/10/2017 - Course Hero b) Recalculate the primary current, IpI _{ p }Ip. Determine whether accelerations or decelerations from the baseline occur. Long-term variability is a somewhat slower oscillation in heart rate and has a frequency of three to 10 cycles per minute and an amplitude of 10 to 25 bpm. The perception that structured intermittent auscultation increases medicolegal risk, the lack of hospital staff trained in structured intermittent auscultation, and the economic benefit of continuous EFM from decreased use of nursing staff may promote the use of continuous EFM.8 Online Table A lists considerations in developing an institutional strategy for fetal surveillance. A concern with continuous EFM is the lack of standardization in the FHR tracing interpretation.5,811 Studies demonstrate poor inter-rater reliability of experts, even in controlled research settings.12,13 A National Institute of Child Health and Human Development (NICHD) research planning workshop was convened in 1997 to standardize definitions for interpretation of EFM tracing.14 These definitions were adopted by the American College of Obstetricians and Gynecologists (ACOG) in 2002,5 and revisions were made in a 2008 workshop sponsored by NICHD, ACOG, and the Society for Maternal-Fetal Medicine.11 The Advanced Life Support in Obstetrics (ALSO) curriculum developed the mnemonic DR C BRAVADO (Table 3) to teach a systematic, structured approach to continuous EFM interpretation that incorporates the NICHD definitions.9,11. Fetal heart rate. The nurse is assessing a fetal monitor tracing and notes that the FHR baseline is 140-150 bpm with decreases to 120 bpm noted beginning after the contraction begins with return to baseline after the contraction ends. Appendix A: Amnioinfusion Appendix B: Selected FHR Tracings and Cases: Interpretation and . electronic fetal heart monitoring trivia quiz questions web mar 22 2022 questions and answers 1 according to awhonn the normal baseline fetal heart rate fhr is a 90 150 A woman has just received pain medication in labor. Fetal Heart Tracing Quiz 1 - 3/10/2017 - Course Hero The nurse has no other patients to care for at this time. Patient information: See related handout on electronic fetal monitoring, written by the author of this article. Tachycardia is certainly not always indicative of fetal distress or hypoxia, but this fetal tracing is ominous. Are there accelerations present? The electronic fetal monitor uses an external pressure transducer or an intrauterine pressure catheter (IUPC) to measure amplitude and frequency of contractions. Self Guided Tutorial. All Rights Reserved. Compared with EFM alone, the addition of fetal electrocardiography analysis results in a reduction in operative vaginal deliveries (NNT = 50) and fetal scalp sampling (NNT = 33). Antepartum Fetal Assessment 10. The NCC EFM Tracing Game uses NICHD terminology. JAMES J. ARNOLD, DO, AND BREANNA L. GAWRYS, DO. Theyre empowered by these results to intervene and hopefully prevent an adverse outcome. Fetal heart tracing is a type of nonstress test that doesnt require any specific preparation. Tracing patterns can and will change! Select the answer that doesn't belong with the others: The incoming nurse enters the patient's room to complete an initial assessment and sees that the FHR has been 80 bpm for the last 3 minutes and that variability is minimal to absent. Strongly Predictive of normal acid-base status at the time of observation. What is the peak voltage across the 3.0F3.0 \mu \mathrm{F}3.0F capacitor? One benefit of EFM is to detect early fetal distress resulting from fetal hypoxia and metabolic acidosis. VEAL CHOP Nursing Mnemonic: Complete Guide - Nurseslabs To assess 5 areas of fetal health: Usually done after 32 weeks, Assesses 5 areas of fetal well-being: The purpose of initiating contractions in a CST is to. Give amnioinfusion for recurrent, moderate to severe variable decelerations, 9. The first uses Doppler ultrasound to monitor FHR patterns, while the second measures the duration and frequency of uterine contractions. The nurse's best response is, b. Variable. Identify pattern of uterine contractions, including regularity, rate, intensity, duration and baseline tone between contractions. Instruct the woman to drink 1 to 2 quarts of water. 2. Interpretation of the FHR variability from an external tracing appears to be more reliable when a second-generation fetal monitor is used than when a first-generation monitor is used.3 Loss of variability may be uncomplicated and may be the result of fetal quiescence (rest-activity cycle or behavior state), in which case the variability usually increases spontaneously within 30 to 40 minutes.19 Uncomplicated loss of variability may also be caused by central nervous system depressants such as morphine, diazepam (Valium) and magnesium sulfate; parasympatholytic agents such as atropine and hydroxyzine (Atarax); and centrally acting adrenergic agents such as methyldopa (Aldomet), in clinical dosages.19. It indicates severe fetal anemia, as occurs in cases of Rh disease or severe hypoxia.24 It should be differentiated from the pseudosinusoidal pattern (Figure 11a), which is a benign, uniform long-term variability pattern. 5. HESI - OB, Fetal Heart Rate: Interpretation Flashcards | Quizlet Together with Flo, learn how fetal heart tracing actually works. Detection is most accurate with a direct fetal scalp electrode, although newer external transducers have improved the ability to detect variability. The organization's practice allows for IA if 1:1 nursing staff is available. See permissionsforcopyrightquestions and/or permission requests. A normal fetal heart tracing would reassure both you and your obstetrician that it's safe to proceed with labor and delivery. Prolonged decelerations (15 beats per minute drop below baseline for more than 2 and less than 10 minutes) Minimal variability. Initiate scalp stimulation to provoke fetal heart rate acceleration, which is a sign that the fetus is not acidotic. Describe a hypothesis that explains these results. 140 145 150 155 160 FHT Quiz 1 Fetal Tracing Quiz Perfect! -4: Suspect lack of adequate oxygen, If >36 wks: deliver, If < 36 wks: Lung Maturity Test The probe sends your babys heart sounds to a computer and shows FHR patterns. It may also be performed using an external transducer, which is placed on the maternal abdomen and held in place by an elastic belt or girdle. Statistical analysis included univariate analyses with Student T-test, one-way ANOVA, chi-square and Fisher exact test. efm.com/fhm/files/quiz2.php?QiD=DCABCC 1/2Correct. et al. The nurse notes a prolonged deceleration of the FHR to 80 bpm and begins intrauterine resuscitation.
