Module 2: Part 4 Flashcards
A sinusoidal FHR pattern is described as:
Smooth and Sine wave-like, undulating pattern with a cycle frequency of 3-5 BPM that continues for at least 20 min or more
What are the causes of sinusoidal FHR patterns? (7)
Rh immunization
Maternal Hemorrhage
Transfusion
Pre-eclampsia
ABRUPTION
Fetal Anemia
Maternal opioids
What are the interventions for sinusoidal FHR patterns? (6)
Maternal blood type
H/O trauma
Oxygenation
GET HELP ASAP
Fetus need Intrauterine transfusion for Anemia?
STAT Cesarean Section
T/F sinusoidal FHR patterns are bad
true
Saltatory pattern may signal…
Acute fetal hypoxia
Excessive swing in variability (more than 25 bpm) is characteristic of what pattern?
Saltatory Pattern
What are 3 “at risk” FHR tracings?
Recurrent late decelerations + no baseline variability
Recurrent variable decelerations + no baseline variability
Substantial bradycardia + no baseline variability
What interventions should be included in the Management of Nonreassuring Tracings? (5)
Left Uterine Decubitus position (LUD)
Stop uterine stimulants (oxytocin)
Terbutaline 0.25 mg SQ
Correct maternal hypotension associated with regional (fluids, ephedrine/neosynephrine)
Oxygen (via mask)
What position should you put the mother in if you see nonreassuring tracings?
Left Uterine Decubitus position (LUD)
ACOG recommends that for HIGH risk you should review the FHR monitor tracing every ___ minutes in first stage of labor and every __ minutes in second stage
every 15 minutes in first stage of labor and every 5 minutes in second stage
ACOG recommends that for LOW risk you should review the FHR monitor tracing every ___ minutes in first stage of labor and every __ minutes in second stage
every 30 minutes in first stage and every 15 minutes in second stage of labor
T/F Haven’t really confirmed a greater benefit with continuous electronic FHR monitoring during labor
true
______ proposed a three-tier system for categorization of FHR patterns
National Institute of Child Health and Human Development (NICHD)
What is category 1 for the Three-Tiered FHR Interpretation System?
Category I (normal): strongly predictive of normal fetal acid-base status at the time of observation, re-eval
What is category 2 for the Three-Tiered FHR Interpretation System?
Category II (indeterminate): not predictive of abnormal fetal acid-base status, but without adequate evidence to classify as normal or abnormal
What is category 3 for the Three-Tiered FHR Interpretation System?
Category III (abnormal): predictive of abnormal fetal acid-base and prompts evaluation/delivery
