Q

Define moderate variability

A

6-25bpm

17
Q

Define marked variability

A

Greater than 25bpm

18
Q

Tachycardia FHR

A

Baseline greater than 160bpm less than 10min, sing of early hypoxemia

19
Q

What are some common causes of FHR tachycardia

A

Infection, prolonged PROM, fetal anemia, drugs (atropine, cocaine)

20
Q

Bradycardia FHR

A

Baseline less than 110bpm for less than 10min

21
Q

What are some common causes of FHR bradycardia

A

Fetal cardiac problem, structural defect, viral infection, CMV, hypoglycemia, hypothermia

22
Q

Define acceleration

A

Abrupt (onset to peak less than 30 sec) increase in FHR above baseline
15bpm, last 15sec, and return to base

23
Q

Are accelerations normal

A

They indicate fetal well being, normal acid-base balance

24
Q

What are early deceleration

A

Onset to lowest greater than 30sec decrease, return to baseline

25
Q

What causes early decelerations

A

Fetal head compression, benign, no intervention

26
Q

What are late decelerations

A

Onset-lowest greater than 30sec, late onset, late recovery; begin after contraction started

27
Q

What traditionally attributes to late decelerations

A

uteroplacental insufficiency

28
Q

What interventions are necessary when late decelerations are present

A

Lateral position, elevate legs, increase IV, discontinue pit, admin oxygen 8-10l, call dr

29
Q

What are variable decelerations

A

Onset to lowest less than 30sec, at least 15bpom decrease in baseline last 15sec and returns to base in less than 2min

30
Q

What causes variable decelerations

A

Compression of umbilical cord

31
Q

What are prolonged decelerations

A

FHR decreases 15bpm, below base last more than 2min less than 10min

32
Q

When is a deceleration considered a baseline change

A

Last longer than 10min

33
Q

What are the interventions when variable decelerations are present

A

Change position (side to side, knee to chest), discontinue oxy, admin 8-10L mask, call Dr., assess for cord prolapse

34
Q

Which category tracing for FHR is considered noraml

A

Category 1

35
Q

What legal responsibility do nurses have when reading fetal monitors

A

Correctly interpret FHR, documenting, timely notification

36
Q

What are the interventions for maternal hypotension

A

Increase IV, lateral position, ephedrine to increase Bp

37
Q

What are the interventions for uterine tachysystole

A

Decrease or discontinue pit, admin uterine relaxant (tocolytic)

38
Q

Define uterine tachysystole

A

Frequent uterine contractions during pregnancy
