Q

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

16
Q

What are decelerations related to fetal heart rate?

A

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

17
Q

What are some causes of deceleration?

A

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

18
Q

What are some causes of early deceleration?

A

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

19
Q

What are nursing interventions related to accelerations or decelerations?

A

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

20
Q

What is prolonged decelerations?

A

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

21
Q

What are reportable conditions related to heart rate monitoring?

A

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

22
Q

What are interventions for cord compression related to decelerations?

A

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

23
Q

What should you do in an emergency?

A

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

24
Q

What are some fetal diagnostic assessments?

A

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

25
Q

What is chorionic villus sampling for?

A

genetic testing in early pregnancy but increases chances of SAB

26
Q

What are some antenatal testing procedures?

A

ultrasound

27
Q

What is a non stress test?

A

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

28
Q

What is a contraction stress test?

A

Induced contractions yield no late decelerations (negative)

29
Q

What is an amniocentesis?

A

used to detect chromosomal assessments and assess maturity of lungs

30
Q

What is an Accelerate Lung Maturity?

A

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

31
Q

What is the phospatidylglycerol test?

A

appears after 35 weeks and determines fetal lung maturity
