Fetal Assessment

Question 1

Prenatal visits:

Answer 1

Every 4 weeks until 28 weeks
Every 2 weeks until 35 weeks
Then weekly until delivery

Question 2

A doppler measures the FHR by sending and receiving continuous ultrasonic waves and emitting the change or shift in pitch frequency of these sound waves

Answer 2

Doppler effect

Question 3

normal fetal HR

Answer 3

110-160

Question 4

• Ultrasound transducer for FHR

External

Answer 4

picks up babies HR

Question 5

Tocotransducer

Answer 5

Picks up tone of mom’s uterus (contractions)

Question 6

IUPC for uterine contractions

Answer 6

Put in b/w presenting part of baby & uterine wall

Used for when baby/mom are in distress

Question 7

Common reasons internal fetal monitoring is used

Answer 7

• 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

Question 8

Internal fetal monitoring =

Answer 8

intensity of contractions

Question 9

What Information is Recorded on the Electronic Fetal Monitor?

Answer 9

Fetal Heart Rate
Maternal Vital Signs
Contractions
Documentation of interventions

Question 10

Fetal Heart Rate Paper top half/bottom half

Answer 10

top: baby
Bottom: mom

Question 11

Degree of variability has 4 categories

Answer 11

Absent
Minimal
Moderate (normal)
Marked

Question 12

Deviations from baseline are indicated as what?

Answer 12

Acceleration

Deceleration

Question 13

Determining baseline HR

Answer 13

need 10-minute segments within the 20 min to get baseline

Question 14

The minimum baseline duration is

Answer 14

two minutes within the ten-minute segment

Question 15

Which deceleration is considered normal?

Answer 15

Early

Question 16

True acceleration criteria:

Answer 16

10-15 BPM for 10-15 seconds

Question 17

What we need with an acceleration:

Answer 17

2 accelerations in 20-minute period

Question 18

Greater than >32 weeks

Answer 18

minimum 15x15

Question 19

Less than 32 weeks=

Answer 19

minimum 10x10

Question 20

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

Answer 20

Baseline variability

Question 21

Amplitude range is undetectable

Zero brain activity; no sudden neuro indications

Answer 21

Absent baseline variability

Question 22

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

Answer 22

Minimal baseline variability

Question 23

Amplitude range is 6 to 25 beats/minute

Answer 23

Moderate baseline variability

Question 24

Amplitude range is >25 beats/minute (concerning)

Answer 24

Marked baseline variability

Question 25

Norms of amplitude:

Answer 25

6-25 bpm

Question 26

VEAL CHOP

Answer 26

* Variable + Cord Compression * Early + Head Compression * Acceleration + Okay * Late + Placental insufficiency

Question 27

Early decelerations caused by

Answer 27

Head compression | Normal process

Question 28

When looking @ strip for early decelerations:

Answer 28

look @ recovery part | Recovery should start earlier than contraction ending

Question 29

Late deceleration is associated with

Answer 29

uteroplacental insufficiency and is a result of hypoxia and metabolic abnormalities

Question 30

Late deceleration: nursing care for intrauterine resuscitation

Answer 30

* 1. Change position * 2. Increase IV fluids (to increase oxygen) * 3. STOP THE PITOCIN INFUSION * 4. Oxygen via mask 8-10 L/min

Question 31

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

Answer 31

Variable decelerations Caused by cord compression

Question 32

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

Answer 32

Prolonged Decelerations

Question 33

If prolapse umbilical cord (emergency event) is suspected:

Answer 33

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

Question 34

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

Answer 34

Sinusoidal Pattern EMERGENCY EVENT: C SECTION
