QUIZ 2

Question 1

baseline FHR

Answer 1

• read over 10 mins

- 110 < FHR < 160

Question 2

bradycardia FHR

Answer 2

baseline < 110 bpm

Question 3

tachycardia FHR

Answer 3

baseline > 160 bpm

Question 4

absent variability

Answer 4

undetectable

Question 5

minimal variability

Answer 5

≤ 5 bpm

Question 6

moderate variability

Answer 6

6-25 bpm

Question 7

marked variability

Answer 7

> 25 bpm

Question 8

sinusoidal pattern

Answer 8

• smooth, sine wave
• cycle frequency of 3-5 min
• lasts 20 mins
• is NOT variability

Question 9

abrupt change

Answer 9

onset to nadir < 30 sec

Question 10

gradual change

Answer 10

onset to nadir ≥ 30 sec

Question 11

acceleration (≥32wks)

Answer 11

• abrupt increase ≥ 15 bpm

- 15 sec ≤ duration < 2 min

Question 12

acceleration (<32wks)

Answer 12

• abrupt increase ≥10 bpm

- 10 sec ≤ duration < 2 min

Question 13

prolonged acceleration

Answer 13

2 min ≤ duration < 10 min

Question 14

early deceleration

Answer 14

onset, nadir, offset coincide w/ contraction

gradual

Question 15

late deceleration

Answer 15

• nadir of FHR occurs after peak of contraction
• offset of FHR occurs after end of contraction
• gradual*

Question 16

variable deceleration

Answer 16

• abrupt* decrease in FHR ≥15 bpm
• 15 sec ≤ duration < 2 min
• may vary in onset, depth, and duration when associated w/ contraction

Question 17

prolonged deceleration

Answer 17

2 min ≤ duration < 10 min

abrupt or gradual

Question 18

recurrent decelerations

Answer 18

occur w/ ≥50% of contractions in 20 mins

Question 19

intermittent decelerations

Answer 19

occur w/ <50% of contractions in 20 mins

Question 20

periodic patterns

Answer 20

FHR patterns associated w/ contractions –> abrupt or gradual onset

Question 21

episodic patterns

Answer 21

FHR patterns not associated w/ contractions

Question 22

Category I

Answer 22

• baseline FHR 110-160 bpm
• moderate variability
• NO late/variable decelerations
• +/- early decelerations
• +/- accelerations

Question 23

Category II

Answer 23

• baseline FHR: brady w/ variability OR tachy
• variability: minimal OR absent w/out recurrent decels OR marked absent
• accelerations: NONE w/ stimulation

Question 24

Category III

Answer 24

• baseline FHR: ABSENT
• recurrent late/variable decels
• brady cardia
• sinusoidal

Question 25

normal uterine activity

Answer 25

≤ 5 contractions in 10 mins

Question 26

tachysystole

Answer 26

> 5 contractions in 10 mins - always check for decels
