Question 3

Baseline FHR

Episodic

definition

Answer 3

changes in baseline of FHR occur independent of UCs

Question 4

Baseline FHR

Recurrent

Definition

Answer 4

changes in FHR occur in greater than or equal to 50% of contractions in 20 min

Question 5

• minimal
• moderate
• marked

Question 7

definition

Answer 7

amplitude undetectable

Question 8

definition

Question 10

Decelerations

4

Answer 10

• early
• variable
• late
• prolonged

Question 11

Early deceleration

Answer 11

gradual decrease in FHR from baseline, same time as contraction

Question 12

Variable deceleration

Answer 12

abrupt decrease in FHR, less than 30 seconds, periodic or intermittent

Question 13

Late deceleration

Answer 13

gradual decrease from baseline taking more than 30 seconds. Nadir at peak of UC, recovers past end of UC. Always periodic

Question 14

Prolonged deceleration

Answer 14

abrupt or gradual decrease in FHR lasting more than 2 min. Periodic or intermittent.

FHR Tachycardia

Answer 15

Baseline >160 lasting 10 min or longer

Question 16

FHR bradycardia

Answer 16

Baseline <110 lasting 10 min or longer

Question 17

4

Answer 17

• frequency (5 or less in 10 min)
• duration (less than 90 secs)
• intensity (subjective)
• resting tone (soft for at least 30 seconds between)

Answer 25

* infection * activity * chronic hypoxemia * cardiac abnormalities * anemia

Question 26

VEAL CHOP (FHR pattern changes)

Answer 26

Variable deceleration: Cord Compression Early detection: Head compression Acceleration: Okay Late Deceleration: Placental Insufficiency

Question 27

POISON (Interventions for FHR changes)

Answer 27

Position (left lateral) Oxygen IV Fluids Scalp stimulation Oxytocin Off Notify Doctor

Question 28

Category I

Answer 28

* normal * indicates well oxygenated fetus * normal acid base balance

Question 29

Category II

Answer 29

* indeterminate * not predictive of abnormal fetal acid balance-not enough evidence

Question 30

Category III

Answer 30

* abnormal * prediction of abnormal fetal acid base balance
