NCC C-EFM CERT. QUESTIONS AND ANSWERS

- 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. - Answer- what is the ONLY true auscultation method? - easy - less charting - lower c/s rates - allows patient movement - non-invasive - cheaper - Answer- 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 - Answer- 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 - Answer- 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) - Answer- 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. - Answer- how does the ultrasound work? - permanent record - central monitoring (every nurse can see it) - non-invasive - doesn't require ROM - Answer- benefits of US? - habitus/large BMI - restrictive to m'vt - computer tries
