AWHONN fetal monitoring course (Answered 100% Correctly) 2024 110-160 normal fetal heart rate range infection, low o2, young what could it mean if FHR is high post date pregnancy what could it mean if FHR is low sonogram what is the number one way to know a babies age amnioinfusion what do you do if theres low amniotic fluid, variable decels kidneys, low urine output, low amniotic fluid if baby is stressed, the baby will divert the blood flow to the brain, heart, and adrenals. this organ won't get good blood flow which will lead to what? 2 what category tracing is absent variability without decels 3 what category tracing is absent variability with decels extrinsic influences on fetal heart patterns that are outside the fetus extrinsic what type of influences are associated with maternal-fetal exchange: -placenta -maternal utero placental circulation -fetal placental circulation -placental transfer -uterine blood flow -umbilical cord -amniotic fluid intervillous space ALL transfer takes place here transient hypoxemia all babies have this with uterine contraction but it's worse with a problematic placenta cord compression when is the only time you give an amnioinfusion intrinsic influences on fetal heart rate that are inside the babies heart ductus venosus, liver for baseline fetal heart rate there must be at least ___ minutes of identifiable baseline segments in a ___ minute window or the baseline for that period is indeterminate 110, 10 bradycardia is a baseline of < ____ bpm for > ___ minutes 160, 10 tachycardia is a baseline of >___ bpm for >___ minutes contractions, high pitocin what can cause bradycardia infection, drugs, hypothyroid, fetal anemia what can cause tachycardia sinusoidal, 20, anemia smooth wavelike pattern for at least ____ minutes, associated with fetal _____ bleeding what can cause sinusoidal FHR baseline variability fluctuations in the baseline FHR that are irregular in amplitude and frequency absent variability undetectable amplitude range minimal variability > detectable amplitude range but less than or equal to 5 bpm moderate variability 6-25 bpm amplitude range marked variability greater than or equal to 25 bpm amplitude range well oxygenated what does variability show a sign that the baby is 3 what category is absent variability with recurrent decels 2 what category is absent variability without recurrent decels recurrent decels minimal variability is unlikely to be associated with hypoxia during labor unless with what? fetal hypoxemia marked variability may be related to what? periodic FHR pattern associated with uterine contractions, p is for pain episodic FHR pattern not associated with uterine contractions recurrent, 20 decelerations that occur with at least 50% of uterine contractions within a ____ minute period intermittent, 20 decelerations that occur with less than 50% of uterine contractions within a ___ minute period accelerations visually apparent abrupt increases in FHR above the baseline 30 accelerations go from onset to peak in less than ____ seconds 15, 15 in fetus 32 weeks or more, the accelerations peak ____ bpm and last for ____ seconds from onset o return to baseline 10, 10 if fetus less than 32 weeks, the accelerations peak ____ bpm and last for ___ seconds from onset to return to baseline prolonged acceleration accelerations greater than 2 minutes but less than 10 minutes in duration gradual greater than 30 seconds from onset to nadir, nadir simultaneous with peak of contraction contractions -mild, moderate, or strong- palpation or internal monitor resting tone soft or hard, palpation or internal monitor 5, 10, 30 normal uterine activity- less than or equal to____ contractions in _____ minutes averaged over a _____ minute window 5, 10, 30 tachysystole - greater than ____ contractions in ____ minutes averaged over a _____ minute window NO is it tachysystole if it is 5 contractions? 7.10 moderate variability is a good sign of an adequately oxygenated baby, guarantees a ph of ____ increase c/s rate there has been no change in anything with fetal monitoring except what intermittent auscultation listening with fetoscope or hand held doppler ultrasound fetoscope detects heart sounds doppler detects reflected sound from heart motion fetoscope detects fhr baseline detects fhr rhythm verifies presence of irregular rhythm detects increases and decreases from FHR baseline clarifies double counting or half counting by EFM doppler detects fhr baseline detects fhr rhythm detects increases and decreases fetal spiral electrode direct monitoring of fetal ECG indicated when continuous detection of FHR clinically necessary and not achievable by US transducer ruptured membranes and 2 cm dilation fetal spiral electrode requires what moms heart rate when the heart rate goes up when contractions goes up, what is on the strip artifact results from mechanical limitations of the monitor, electronic interference or weak signal. appears as gaps or dots with external monitoring and irregular lines of varying lengths with a fetal scalp electrode hepatitis out of herpes, hiv, placenta previa, hepatitis, what can you use the fetal spiral electrode with fingertips when palpating to assess uterine activity, what do you put on the maternal abdomen over the area where changes in uterine firmness is best felt (usually funds) toco detects changes in shape of abdomen resulting from uterine tension pressure what does the toco detect from the uterine muscle intrauterine pressure catheter quantitative measurement for strength of contractions and resting tone; still have to palpate variable decels
