Q

Common reasons internal fetal monitoring is used

A
  • Baby is difficult to monitor
  • Baby has an abnormal heart rate
  • Determining strength of contractions
  • The patient is on Pitocin (intensifies contractions)
  • Should have an internal monitor

16
Q

True acceleration criteria:

A

10-15 BPM for 10-15 seconds

17
Q

What we need with an acceleration:

A

2 accelerations in 20-minute period

18
Q

Greater than >32 weeks

A

minimum 15x15

19
Q

Less than 32 weeks=

A

minimum 10x10

20
Q

Ability of brain to work with heart to change beats second to second

A

Baseline variability

21
Q

Amplitude range is undetectable

Zero brain activity; no sudden neuro indications

A

Absent baseline variability

22
Q

Amplitude range is less than 5 beats/minute or fewer
Lowest to highest range is less than 5 bpm amplitude
Some type of change by not enough

A

Minimal baseline variability

23
Q

Amplitude range is 6 to 25 beats/minute

A

Moderate baseline variability

24
Q

Amplitude range is >25 beats/minute (concerning)

A

Marked baseline variability

25
Q

Norms of amplitude:

A

6-25 bpm

26
Q

VEAL CHOP

A
  • Variable + Cord Compression
  • Early + Head Compression
  • Acceleration + Okay
  • Late + Placental insufficiency
27
Q

Early decelerations caused by

A

Head compression

Normal process

28
Q

When looking @ strip for early decelerations:

A

look @ recovery part

Recovery should start earlier than contraction ending

29
Q

Late deceleration is associated with

A

uteroplacental insufficiency and is a result of hypoxia and metabolic abnormalities

30
Q

Late deceleration: nursing care for intrauterine resuscitation

A
    1. Change position
    1. Increase IV fluids (to increase oxygen)
    1. STOP THE PITOCIN INFUSION
    1. Oxygen via mask 8-10 L/min
31
Q

An ABRUPT decrease in FHR & With an abrupt return to baseline

A

Variable decelerations

Caused by cord compression

32
Q

A decrease in FHR lasting >= 2 minutes but less than 10 minutes

A

Prolonged Decelerations

33
Q

If prolapse umbilical cord (emergency event) is suspected:

A

Initiate Knee Chest positioning and/or gentle pressure on presenting part

34
Q

It consists of an undulating form of sine wave that is regular, smooth and undulating

A

Sinusoidal Pattern

EMERGENCY EVENT: C SECTION
