What is the primary cause of variable decelerations?
Reduced flow through the umbilical cord
What is a characteristic of early decelerations?
They are mirror images of contractions
What is NOT a characteristic of early decelerations?
They are associated with fetal compromise
What is the significance of variable decelerations?
They require nursing intervention
What is the shape of variable decelerations?
An abrupt fall and rise in rate
What is the normal range of baseline variability in fetal heart rate?
2-25 BPM
What is the definition of accelerations in fetal heart rate?
A temporary increase in FHR of 2 or more bpm for 15 seconds in 20 minutes
Which type of deceleration is associated with head compression?
Early deceleration
What is the significance of accelerations in fetal heart rate?
They are a sign of a healthy fetal response
What is the definition of decelerations in fetal heart rate?
Decreases in FHR defined by their relationship to contractions
What is the category of a normal finding in prelabor fetal testing?
Category I
What is the primary goal of maternal assessment in labor?
To safeguard mother and infant
What is the normal range of fetal heart rate (FHR) in beats per minute?
110-160 BPM
What is the purpose of Leopold's maneuvers in fetal assessment?
To identify fetal position
What is the advantage of intermittent auscultation in low-risk women?
It allows for mobility and a more natural atmosphere
What is the definition of bradycardia in fetal heart rate?
Fetal heart rate less than 110 BPM
What is the purpose of electronic fetal monitoring (EFM)?
All of the above
What is the normal flow of oxygenated maternal blood into the placenta?
Normal flow of oxygenated maternal blood into the placenta
What is a pathologic influence on fetal oxygenation?
Maternal cardiopulmonary alterations
What is the limitation of intermittent auscultation?
Uterine activity is assessed for a small part of the total labor
What is the interpretation of a fetal heart rate with a baseline of 140, regular in rate, and without decelerations after the contraction ends?
Fetal well-being
What is the primary concern associated with late decelerations in fetal heart rate patterns?
Fetal hypoxia and possible acidosis
What is the definition of a reassuring fetal heart rate pattern?
A rate of 110-160 bpm with moderate variability
What is the primary goal of nursing interventions in response to non-reassuring fetal heart rate patterns?
To improve placental perfusion and fetal oxygen supply
What is the characteristic of a sinusoidal fetal heart rate pattern?
None of the above, as it is not a recognized pattern
What is the appropriate response to a prolonged deceleration in fetal heart rate patterns?
Change the maternal position to reduce cord compression
Why is it important to identify the cause of a non-reassuring fetal heart rate pattern?
To develop targeted nursing interventions to improve fetal outcomes
What is the primary purpose of administering O2 via face mask in a non-reassuring FHR pattern scenario?
To increase fetal oxygenation
Which of the following FHR patterns is associated with fetal well-being?
Category I: Normal
What is the primary intervention for maternal hypotension in a non-reassuring FHR pattern scenario?
Elevating the maternal legs
What is the significance of Category III FHR tracings?
Favorable signs are absent
What is the significance of late or variable decelerations in a FHR tracing?
They are associated with fetal distress
What is the purpose of internal fetal monitoring in a non-reassuring FHR pattern scenario?
To confirm a non-reassuring FHR pattern
This quiz covers the normal and pathologic mechanisms that influence fetal heart rate, types of equipment used for electronic fetal monitoring, and the advantages and limitations of each. It also identifies the Three Tier Interpretation of Electronic Fetal Monitoring. Test your knowledge of intrapartum care and fetal heart monitoring!
