Chapter 13 Flashcards
uterine contractions
tachysystole
more than 5 in 10 minutes
uterine contractions
normal
less than 5 in 10 minutes
Latent phase dilation
0-6cm
Latent phase: contraction
- freq
- duration
- strength
Every 5-10 minutes
30-45 seconds
Mild to palpation
Active phase dilation
6-10 cm
active phase Cervical effacement
40%-100%
active phase Duration for nullipara vs multipara
Nulli: up to 6 hrs
Multip: up to 4 hrs
Active phase: contraction
- freq
- duration
- strength
Every 2-5 minutes
45-60 seconds
Intensity moderate to palpation
When do fetal membranes typically rupture
During dilation stage (possibly before or may remain intact until birth)
expulsive stage
Contractions: duration, frequency, strength
Occur every 2-3 minutes
Last 60-90 seconds
Strong to palpation
What outcome is associated with longer stage 2
Negative maternal outcome
- higher rate of puerperal infection
- third- and fourth degree perineal laceration
- postpartum hemorrhage
Physiological changes during placental separation step
- Uterus rises up
- Umbilical cord lengthens
- Sudden trickle of blood
- Uterus changes shape to globular
Nurse mgmt. during restorative phase
Close monitoring of mother and newborn Mother -bladder distension -venous thrombosis -lochia (every 15 min for 1 hour) -fundus (every 15 min for 1 hour) -VS (every 15 min for 1 hour)
Cardinal movements of labor
Engagement Descent Flexion (around 0) Internal rotation (to get past spines) Extension External rotation (to get shoulders out, top before bottom) Expulsion
Maternal
Increased heart rate
Increased cardiac output
Increased blood pressure (during contractions)
Increased WBC*
Increased respiratory rate and oxygen consumption
Decreased gastric motility and food absorption
Decreased gastric emptying and gastric pH
Slight temp elevation
Muscle aches/cramps
Decreased blood glucose levels*
