19
Q

What is a non-stress test or electronic fetal monitoring?

A

assessment of fetal oxygenation & autonomic function

20
Q

What is considered a reactive non stress test?

A

accelerations of 15 beats/min lasting 15 seconds with fetal movement

21
Q

What is considered a nonreactive non stress test?

A

no accelerations of FHR with fetal movement

22
Q

How do you assess fetal movement?

A

beginning at 27-28 weeks. daily, about 1 hour after a meal. lie on side and count movements until 10 are felt. keep a record and note/report diminished rate of movement.

23
Q

When should you contact a doctor with fetal movement?

A

> 10 kicks in an hour or less than 4 in 30 minutes

24
Q

What is the purpose of amniocentesis?

30
What are the principles underlying use of drugs in pregnancy?
