Q

purpose and use of fetal monitoring in labor

A
  • ID signs of fetal well-being or compromise
  • assess both FHR and UC’s
  • no method of fetal assessment can ID every compromised fetus
  • poor predictive value
  • low tech approach (intermittent auscultation (doppler)
  • high tech approach continuous monitoring

Q

fetal monitoring as a major role for medical malpractice

A
  • documentation is key (nurse’s must document and prove standard of care was met)
  • nurse should identify abnormal/non-reassuring findings, intervene and report to MD/CNM in timely manner

Q

fetoscope or doppler

A
  • peform leopold’s manuevers and place doppler over area of maximal intesity of fetal heart tones
  • palpate maternal artery at same time
  • determine relationship of contraction and FHR by palpating for contractions during the FHR auscultation
  • count FHR between cotraction for at least 30-60 seconds to determine baseline
  • determine differences between baseline FHR and response to contraction

Q

external fetal monitor parts

A
  • ultrasound transducer: recevies waveforms from fetal heart interpreted by the computer in the fetal montior to produce sound and visual tracing to reflect FHR
  • toco- strain gauge that detects skin tightness or contour changes resulting from UC’s
  • monitor paper

Q

internal electronic fetal and uterine monitoring

A
  • uses fetal scalp electrode (FSE) or internal scalp electrode applied to fetus presenting part to directly detect FHR
  • internal electronic uterine monitoring involves an IUPC placed in uterine cavity to directly measure contractions
  • membranes must be ruptured
  • needs this when troubleshooting methods that do not alter the quality of tracing, maternal obesity, lack of progress in labor
  • contraindication: infections, placenta previa, undiagnosed vaginal beleding

Q

monitoring fetal paper

A
  • each dark vertical line represents 1 minute and each lighter vertical line represents 10 seconds
  • FHR recorded on top fird in bpm while UC recorded on lower grid in mmHg with IUPC and relative height for TOCO
  • thin vertical lines (or boxes) = 10 seconds apart
  • heavy vertical lines = 1 minute apart

Q

determining if accel’s are present

A
  • transitory abrupt increases in FHR above baseline that last <30 seconds from onset to peak
  • determine if present or absent
  • always reassuring, occurs with fetal movement or stimualtion
  • if present and 15x15 (abrupt increase by at least 15 beats above baseline for at least 15 seconds) it is reactive
  • this strip has a FHR baseline of 145 and is reactive because FHR baseline has increase to at least 160 for minimally 15 seconds
