Flashcards in Fetal Assessment Deck (31):
1

What are 3 ways to hear a fetal heartbeat?

Fetoscope, Doppler, FetalHeart Rate Monitor

2

How old is a fetus when you use a doppler to hear a heartbeat

12 weeks

3

How high should the fundal height be?

26-30cm

4

What is Leopold's Maneuvers?

Palpating and assessing firm and soft parts to identify the fetal part in the uterus

5

What does Leopold's Maneuvers check for?

Fetal position, presentation, and movement, engagement, uterine irritability, contractions, and estimated fetal weight

6

What does electronic fetal monitoring do?

Records fetal heart activity continously

7

What is the external mode of electronic fetal monitoring? (2 Types)

Tocotransducer- placed on fundus for uterine contraction or Doppler- placed below umbilicus for HR monitoring

8

When is internal fetal monitoring used?

After membranes are ruptured and the cervix is dilated.

9

What is a spiral electrode?

A small thing placed on the scalp or presenting part of fetus to monitor the HR

10

What is an intrauterine pressure catheter used for?

To monitor uterine contractions

11

What is a baseline fetal heart rate?

110-160 bpm

12

What is considered tachycardiac for a fetus?

greater than 160 bpm

13

What is considered bradycardic for a fetus?

less than 110 bpm

14

What does Accelerations mean related to heart rates?

an abrupt increase in heart rate above the baseline

15

What are some causes of accelerations?

Spontaneous movement, a vaginal exam, electrode application, breech presentation, loud sounds, contractions, anything that might upset the baby

16

What are decelerations related to fetal heart rate?

decreases in heart rate in response to activity or uterine contraction.

17

What are some causes of deceleration?

pressure on the fetal head, umbilical cord compression, decreased oxygen transfer

18

What are some causes of early deceleration?

head compression from the uterus, vaginal exam, fundal pressure, or placement of an internal mode.

19

What are nursing interventions related to accelerations or decelerations?

Change mothers position, elevate legs, increase IV, palpate uterus, stop pitocin

20

What is prolonged decelerations?

HR of 15 bpm below the baseline or lasting more than 2 minutes but less than 10 minutes

21

What are reportable conditions related to heart rate monitoring?

Nonreassuring patterns, decelerations, late decelerations, no variability, severe bradycardia, fetal dysrhymias

22

What are interventions for cord compression related to decelerations?

Change the mothers position, stop pitocin, adminiser oxygen, place mother with butt in the air

23

What should you do in an emergency?

Maximize the fetal oxygen- reposition woman in lateral position, administer oxygen, increase fluids, assess for bleeding

24

What are some fetal diagnostic assessments?

Chorionic Villus Sampling, umbilical blood sampling, serum alpha fetal protein for neural tube defects

25

What is chorionic villus sampling for?

genetic testing in early pregnancy but increases chances of SAB

26

What are some antenatal testing procedures?

ultrasound

27

What is a non stress test?

Mother eats to stimulate baby and a doppler ultrasound measures the HR, accelerations with movement

28

What is a contraction stress test?

Induced contractions yield no late decelerations (negative)

29

What is an amniocentesis?

used to detect chromosomal assessments and assess maturity of lungs

30

What is an Accelerate Lung Maturity?

Testing for surfactant in the lungs, it will be present in the amniotic fluid at 26 weeks

31

What is the phospatidylglycerol test?

appears after 35 weeks and determines fetal lung maturity
