Q

What is fetal position?

A

Presentation in relation to maternal pelvis. Maternal pelvis divided into 4 quadrants -anterior, posterior, right, left. What part is presenting is oriented to position of mom’s pelvis. So occiput, mentum (chin) or sacrum can present in anterior, posterior, left, right quadrants.

25
What is supine hypotensive syndrome?
Mom lies flat-baby impedes blood flow-BP drop in mom
26
What is bloody show?
Warning sign of impending labor called a premonitory sign. Mix of thick, bloody mucus discharge shows cervical ripening
27
What are Braxton Hicks contractions?
Milder, irregular, contractions that are a warm up for real labor. Called a premonitory sign.
28
What is lightening in labor language?
Dropping of baby as fetus descends toward pelvis. Premonitory sign of impending labor.
29
What is false labor called?
Prodromal labor
30
What are the three phases of stage 1 labor?
Latent (early)-Start to about 3-5cm Active-4-8cm contractions more intense-Internal rotation happening. Transition-8-10 cm contractions the most intense.
31
What is an amniotomy?
Artificial Rupture of Membranes (AROM)
32
What does SROM mean?
Spontaneous rupture of membranes
33
What 5 things does APGAR assess?
Appearance, pulse, grimace, activity, respiration.
34
What is a normal fetal heart rate range?
110-160 bpm
35
When is Apgar done after delivery?
minute 1 and minute 5
36
Heart rate on Apgar is classed as 0 1 2 What does this mean?
0=no heart beat 1=less than 100 bpm 2=100 bpm or more
37
Respiratory effort on APGAR is classed as 0 1 2 What does this mean?
0=no respirations 1=slow respirations or weak cry 2=spontaneous respirations and strong cry
38
Muscle tone on APGAR is classed as 0 1 2 What does this mean?
0=limp 1=minimal flexion of extremities, sluggish movement 2=flexed body posture, spontaneous and vigorous movement
39
Reflex response on APGAR is classed as 0 1 2 What does this mean?
0=no response to suction or gentle slap on soles 1=minimal response to suction or gentle slap on soles 2=responds with cry or active movement to suction or gentle slap on soles
40
Color on APGAR is classed as 0 1 2 What does this mean?
0=pallor of cyanosis 1=bluish hands and feet only 2=pink or absence of cyanosis In dark skinned baby look at mucous membranes
41
If an Apgar score is <3 what actions should be taken?
Resuscitation
42
If APGAR score is 4-6 what actions should be taken?
Gently stimulate by rubbing and administering oxygen. May be from pain meds
43
If APGAR score is 7-10 what action should be taken?
None
44
What is tocodynamometer?
TOCO-Measures strength of contractions. Pressure sensor strapped to belly
45
What is fetal tachycardia?
>160 bpm for 10 minutes
46
What is fetal bradycardia?
<110 bpm for 10 minutes
47
How is Doppler used in labor?
Used to listen to baby's heartbeat to gather rate, rhythm, and changes
48
What is included in EFM? ---Electronic Fetal Monitoring--
Several different methods of gathering info but basically getting fetal heart rate (FHR) and uterine activity on strip. Can leave on continuously or intermittently
49
What is baseline fetal heart rate?
The average bpm rounded to the nearest 5, measured over 2 minutes with no interfering factors or contractions. Classed as normal, tachy or brady.
50
What is variability in EFM? ---Electronic fetal monitor--
Variability is the fluctuations in the baseline FHR. Look like irregular waves in the line. These are closely studied because they can indicate how well baby is oxygenated and tolerating labor. But it also is affected by any interference and can be tricky getting an accurate reading.
51
What are accelerations?
Increase in FHR that lasts at least 15 seconds and increases at least 15 bpm. Usually from fetal movement and a positive sign of healthy baby.
52
What are three types of decelerations?
Early Late Variable These are based on their shape and relationship to contractions.
53
What are early decelerations?
Normal. FHR decreases as contraction peaks. Caused by baby's head being squeezed by contraction. The "nadir" is the low point of FHR during contraction.
54
What are late decelerations?
Not a good sign. Same as early decelerations except the nadir in FHR is slightly to right of peak of contraction. Sign of poor oxygenation in baby.
55
What are variable decelerations?
Drop in FHR that has no relationship or pattern
56
What is an IUPC?
Intra Uterine Pressure Catheter Inserted into uterus through vagina to measure contractions. Some allow for amnioinfusion-which is infusion of sterile solution into uterus.
57
What is meant by precipitous labor and birth?
Fast! Less than 3 hours. Greater risk for bleeding.
58
What is meant by malpresentation?
Breech. Not head first.
59
What does caput mean?
Cone head
60
What does it mean when baby is vertex?
Head down and occiput presenting
61
What is it called when shoulder gets stuck in delivery?
Shoulder dystocia
62
What is engagement?
Station of baby in relationship to ischial spines (little nodules on inside of pelvis) This is the tightest point and if baby's head can pass through this then he will be able to fit. Range of -3 to +3 with 0 being the point of top of head at ischial spines.
63
How long do contractions typically last in latent phase of labor?
Frequency is 10-30 min in early then progressing to 5-7 min later in early labor Duration is 30 seconds and mild intensity
64
Character of contractions in active phase of labor.
Frequency is every 2-5 min 40-60 seconds in duration Moderate in intensity
65
Character of contractions in transition phase of labor.
Frequency is 1.5 -2 min 60-90 seconds in duration Strong in intensity
66
What happens to WBC in labor?
Elevated to 25-30K
67
How are FHR strips categorized?
Cat 1-normal Cat 2-indeterminate Cat 3-abnormal
