NURS 368 EFM EXAM QUESTIONS AND CORRECT ANSWERS
What is the purpose of fetal surveillance before birth? -ANWER -MAXIMIZE
OXYGENATION
-maximize umbilical blood flow
-support maternal coping and labor progress
-maximize uterine blood flow
-maintain appropriate uterine activity
What is Electronic fetal monitoring? why do we care? -ANWER •tool for visualizing fetal
heart rate (FHR) patterns on a monitor screen or printed tracing
•Fetal well-being (oxygenation!) during labor is assessed by response of the FHR (fetal
heart rate) with & without UCs (uterine contractions)
What are the 5 essential components of FHR - ANSWER -baseline FHR, variability,
accelerations, decelerations, and changes in FHR over time.
What is Intermediate feal monitoring - ANSWER •Auscultation (IA) &
Palpation (of cx's)
What is continuous fetal monitoring - ANSWER Electronic Fetal Monitoring (EFM)
internal and external
External Fetal Monitoring - ANSWER •Non-invasive
-"Toco"-Transabdominal - Tocotransducer for u/c
, -Ultrasound transducer detects FHR (thump, thump)
Internal Fetal Monitoring - ANSWER •Invasive - Membranes must be ruptured, cervix
sufficiently dilated and presenting part low
-Spiral Electrode for FHR
-Internal Uterine Pressure Catheter (IUPC) for uterine contractions
What are the normal and pathological mechanisms that influence fetal heart rate (FHR)?
- ANSWER
What are the advantages of auscultation? Disadvantages? - ANSWER NEED TO GET
What are the advantages of Electronic monitoring? Disadvantages? - ANSWER NEED TO
GET
What can Tocotransducer not do - ANSWER cannot determine tone or contractions
only IUPC can see tone
What can you assess through palpation - ANSWER -The frequency, duration, tone, and
intensity of contractions
•Mild or 1+ (easily dented)
•Moderate or 2+ (can slightly indent)
•Strong or 3+ (cannot indent uterus)
Peak intensity [FHR] - ANSWER •mild, moderate, strong by palpation
•w/IUPC - 50-75 mm Hg, up to 110 mm Hg w/pushing
Resting tone [Intensity] - ANSWER •want 5-15 mm Hg, up to 20 mm Hg (w/IUPC)
