Intra part 2 Flashcards
Involuntary uterine contraction causes progressive effacement and dilatation
Labor
Actual expulsion of the products of conception, fetus and placenta
Delivery
Birth less than 37 weeks
Pre term
Birth within 37 - 42 weeks
Term
Birth beyond 42 weeks
Post term
14 to 20 hours of labor
Primipara
8 to 14 hours of labor
Multipara
Beginning of labor, and may begin several weeks prior to labor
Impending signs of labor
Fetus settles or descends into pelvic inlet and occurs 10 - 14 hours before onset of labor.
Lightening
Settling of the presenting part into pelvic inlet
Engagement
Increased frequency of contractions which produces gnawing pain in abdomen and groin.
Increased Braxton-Hick’s Contraction
Cervix feels “butter-soft” and felt only on pelvic exam.
Ripening of the Cervix
Due to increase of epinephrine as initiated by decrease of progesterone produced by the placenta.
Sudden burst of energy of the mother
Increases prostaglandin and cortisol levels to help with contractions
Epinephrine
Neurotransmitter that prepares the mom’s body for labor work
Epinephrine
Overwhelming desire to organize and prepare the home of the coming baby
Nesting Instinct
Loss of 2-3 pounds and happens 2-3 days before onset of labor
Allowable weight loss
Fetus is already engaged in the pelvic inlet
Less active fetal movement
Contractions begin and remain irregular
False Labor
Increases intensity of contraction
True labor
Contractions begin irregularly but become regular and predictable
True labor
Pain often disappear with ambulation and sleep
False labor
Intensity of contractions does not increase
False Labor
Pain is felt first abdominally and remained confined to the abdomen and groin
False Labor
Pain continues no matter what the woman’s level of activity
True Labor
Does not achieve cervical dilatation
False Labor
Pain is felt first in the lower back and sweep around to the abdomen in a wave
True Labor
Achieves cervical dilatation
True Labor
The fetus usually becomes engaged in the pelvis
True labor
Expulsion of mucus plug due to softening of cervix and blood from ruptured capillaries due to pressure from fetus
Bloody Show
Surest sign that labor has begun its productive uterine contractions
True Labor
Sudden gush or trickle of amniotic fluid from vagine
Spontaneous Rupture of Membrane
Thinning and shortening of cervix and measured in percentages
Effacement
Widening of the external cervical OS
Dilation
From beginning of contraction until it increases, and starts at fundal area.
Increment of Crescendo
Height or peak of contraction, and continues at the side of abdomen
Acme
From the height of contraction until it decreases
Decrement
From increment to decrement, of same/single contraction.
Duration
From beginning of increment to increment of another contraction
Frequency
From decrement of 1 contraction to another period of increment of next contraction. ( no contraction)
Interval of Rest
Considers the peak on contraction
Strength
Dilating stage, from true contraction to full cervical dilation, and is the longest stage
First stage of labor
Stage of expulsion, from full cervical dilation to delivery of fetus, and is the shortest stage
2nd Stage of labor
From delivery of fetus to delivery of placenta
Third stage of labor
Immediate recovery period, from delivery of placenta to 1 - 4 hours after delivery
Fourth stage of labor
Period from onset of contractions to full dilation and effacement of the cervix.
1st Stage of labor
1st stage of labor is divided into three phases
Latent, Active, Transitional
Mother becomes tired, restless and irritable
Latent Phase
Mother becomes anxious as contractions become stronger
Active Phase
Mother is talkative and eager to be in labor
Latent Phase
Dilation is 0-3 cm
Latent Phase
Contractions happens every 3 to 5 minutes
Active Phase
Dilation is between 4 - 7 cm
Active Phase
Contractions lasts up to 20 - 40 seconds
Latent
Dilation is between 8 - 10 cm
Transitional
Contractions happen every 5 - 10 minutes
Latent
Contraction lasts 30 - 60 seconds
Active
Contractions are mild
Latent
Contractions lasts 45 - 90 seconds
Transitional
Contractions are moderate in pain
Active
Contractions happens every 2 - 3 minutes
Transitional
Contractions are severe
Transitional
When are maternal vital signs taken in the latent phase
every 1 hour
When are maternal vital signs taken in the active phase
every 30 minutes
When are maternal vital signs taken in the transitional phase
every 15 minutes
