MATERNAL ASSESSMENT OF FETAL
ACTIVITY - (KICK COUNTS) |
|
Definition
Low tech, inexpensive
b) Decrease in movement could indicate fetal
hypoxia, IUGR, fetal death
c) Shown correlation with fetal mortality and
decreases maternal anxiety
d) Maternal education on fetal movement
record (FMR)(Cardiff Count-To-10)
i) Daily beginning at 27 – 28 weeks
ii) Same time every day about 1 hour after
meal
iii) Side lying
iv) Count 10 movements with X on card
(1) Goal less than 3 hours
v) When to call:

Term
|
Definition
1. Offers a valuable means of assessing intrauterine fetal growth.
2. It is noninvasive and painless.
3. It allows the certified nurse midwife or physician to study the gestation serially.
4. It is non radiating to both the woman and her fetus. It has no known harmful effects. |

Term
| ULTRASOUND (Indications/timing) |
|
Definition
i) FHR activity, validate pregnancy/ 5-6
weeks
ii) Gestational age/ 6-10 weeks and 13 – 40
weeks
iii) Fetal growth
iv) Fetal anatomy
v) Placental growth/position
vi) Adjunct to other testing |

Typically used early in
pregnancy
(1) Lithotomy position
(2) Long probe, covered by sheath,

|
Term
|
Definition
| a combination of an ultrasound and a nonstress test to assess a fetus at risk for intrauterine compromise |
|
|
Term
| biophysical profile includes five variables |
|
Definition
◾Fetal breathing movement
◾Fetal body movement
◾Fetal tone
◾Amniotic fluid volume
◾Fetal heart rate reactivity |

Term
|
Definition
evaluates respiratory function of the placenta.
◾The woman is attached to an electronic fetal monitor and contractions are stimulated. This evaluates the ability of the fetus to handle contractions. The procedure might precipitate labor prematurely.
◾The desired result is a negative test. |
|
|
Term
|
Definition
based on the knowledge that the FHR normally increases in response to fetal activity and to sound stimulation.
◾The woman is attached to an electronic fetal monitor for approximately 20 minutes. She is required to lie still during the test.
◾The desired result is a reactive test. |
