Q

Measures the response of sound waves against solid objects

A

ultrasonography

20
Q

in ultrasonography, sound waves are sent through abdomen or vagina by a device called a ___

A

transducer

21
Q

true or false: ultrasonography uses radiation like xrays

22
Q
  • Measures the velocity @ which RBC in the uterine & fetal blood vessels travel
  • Assessment of the blood flow through the uterine blood vessels is helpful to determine the vascular resistance present in women with diabetes or hypertension of pregnancy and whether resultant placental insufficiency is occurring
A

doppler umbilical velocimetry

23
Q

fetal lungs are apt to be mature at 38 weeks, a grade 3 placenta suggest that fetus is mature

A

placental grading

24
Q

how to measure amniotic fluid for <20 weeks

A
  • divide in half vertically
  • Measure the vertical diameter of the largest pocket of amniotic fluid present on each side in cm, then add
25
how to measure amniotic fluid for >20 weeks
- divide into 4 quadrants - Measure the vertical diameter of the largest pocket of amniotic fluid present on each quadrant in cm, then add
26
average amniotic fluid volume index between 28-40 weeks
12-15 cm
27
afi index > 20-24 cm
polyhydramnios
28
afi index < 5-6 cm
oligohydramnios
29
- identifies whether an increase in the FHR occurs when the fetus moves, indicating adequate oxygenation - measures the response of the fetal heart rate to fetal movement
nonstress testing
30
how long is nonstress testing done
10-20 mins
31
when do you perform nonstress testing
28 weeks
32
nonstress interpretation: 2 accelerations of FHR (by 15 beats or more) lasting for 15 seconds occur after movement within the chosen time period
reactive (normal)
33
nonstress interpretation: - No accelerations occur with the fetal movements - No fetal movements occur or if there is low short term fetal heart rate variability (less than 6 bpm) throughout the testing period
nonreactive
34
If no increase in beats per minute is noticeable on fetal movement, ___ of the fetus is suggested.
poor oxygen perfusion
35
- Non-invasive test done after the 28th week of pregnancy - helps evaluate the health of the fetus
biophysical profile
36
BPP combines five parameters into one assessment:
1. Fetal heart reactivity 2. Fetal breathing 3. Fetal body movement 4. Fetal tone 5. Amniotic fluid volume
37
criteria for a score of 2: fetal breathing
30 second sustained fetal breathing within 30 min
38
criteria for a score of 2: fetal movement
atleast 3 episodes of limb or trunk movement within 30 mins
39
criteria for a score of 2: fetal tone
must extend and flex extremities atleast once in 30 mins
40
criteria for a score of 2: AF volume
5-25 cm
41
criteria for a score of 2: fetal heart reactivity
2 or more acceleration of atleast 15 bpm above baseline for 15 seconds with fetal movement within 20 mins
42
8-10 BPP score
fetus is doing well
43
6 BPP score
suspicious
44
4 BPP score
fetus in jeopardy
45
Movements by the fetus, as assessed by the mother, are often called ___
kick counts
46
how to do daily kick count
- count once a day for 60 mins - count 2-3x daily for 2 hours OR until 10 movements are counted
47
fetal alarm signal regarding kick count
no movement for 12 hours
