- fetoscope! listens to how the valves of the heart close - Fetoscope is the only true auscultation tool. Doppler picks up heart motion. Fetoscope listens to the valves closing. correct answers what is the ONLY true auscultation method? - easy - less charting - lower c/s rates - allows patient movement - non-invasive - cheaper correct answers benefits of fetoscope/auscultation? - requires 1-to-1 nursing care - can't assess variability - maternal habitus can cause an issue - anterior placenta - high BMI - firm uterus correct answers limitations of fetoscope/auscultation? includes ALL of the following: - normal FHR baseline b/w 110-160 - regular rhythm - presence OR absence o/f FHR increases or accels from the baseline rate - absence of FHR decreases or decels from baseline correct answers category I FHR criteria? include ANY of the following: - irregular rhythm - presence of FHR decreases or decels from baseline - tachycardia (baseline > 160 for > 10 min) - bradycardia (baseline < 110 for > 10 min) correct answers category II FHR criteria? - Used to detect fetal heart motion from sound waves that are then transmitted to a computer to produce the audible sound and visual tracing - Second generation monitors use technology that autocorrelates the waveforms that are received and creating the smoothing of the waveforms. This is why we don't have short term vs long term variability anymore. correct answers how does the ultrasound work? - permanent record - central monitoring (every nurse can see it) - non-invasive - doesn't require ROM correct answers benefits of US? - habitus/large BMI - restrictive to m'vt - computer tries to predict a normal HR so it may attempt to half or double FHR - hard to detect arrhythmias - maternal and fetal movement may interfere with continuous monitoring correct answers limtations of US?
