NUR 102 Exam 1 Intrapartal Care Flashcards
What is a visually abrupt increase in fetal heart rate of 15 or more beats per minute above baseline?
Accelerations
What’s a rapid assessment of five physiological signs that indicate the physiological status of the newborn at birth?
The Apgar score
What is Amniotomy?
(AROM) The artificial rupture of membranes?
What is the average FHR over 10 minute segment EXCLUDING episodic changes?
Baseline FHR
What is beat to beat changes in baseline?
Variability
What is a physiological and mechanical process in which uterine muscles contract and retract rhythmically resulting in delivery of baby & placenta?
LABOR
What is a force (contraction) exerted on a movable object (baby) meeting resistance (cervix&pelvic floor) resulting in a gove (effacement, dilation and descent)?
LABOR
> Fetus undergoes changes in position (rotation)
Purpose is to present smallest possible diameter of presenting part to irregular shape of pelvic canal
and to decrease resistance. This is called what?
The mechanism of Labor
What maternal factors trigger labor?
Secretion of hormones to stimulate contractions
What fetal factors trigger labor?
> Aging placenta
>Secretion of hormones by fetus
What are the 6 signs of impending labor?
>Lightening = Baby drops >Braxton-Hicks Contraction >Cervical softening or "ripening" >Weight loss and/or GI disturbances >Burst of Energy >Bloody show
Can you go into labor without any of the 6 signs of labor?
YES YOU CAN!
What are the 4 S&S of TRUE LABOR?
> Uterine contractions which are regular, become more frequent and intense
Cervical changes
Bloody show (loss of muscous plug)
Rupture of membranes (may occur before labor begins or during labor
Do Braxton -Hicks contractions change the cervix?
NOO NOT AT ALL!!
What is PROM?
Premature Rupture of Membranes
PROM can cause what?
Septicemia
The 5 “Ps” that affect labor are called what?
What do they stand for?
> Power-uterine contractions, abdominal muscles of mother while pushing
Passageway- Pelvis-size & shape; soft tissue
Passenger -size, position & presentation
Position- frequent changes during the 1st and 2nd Stages
Psyche- response of the woman i.e if she doesn’t want to push anymore.
What is a nice shape pelvis? (passageway)
Gynecoid
We want the baby’s head at what station? where is this located anatomically?
ZERO STATION
The Ischial Spine
What is it called when the baby’s (passenger) head is too large to fit through mother’s pelvis?
Cephelopelvic disproportion (CPD)
What’s another word for the “Position” of the baby?
Attitude
What is the normal attitude (position) for the passenger?
Norm=flexed:head toward the chest, arms and legs flexed over thorax, back curved in “C”
Baby is laying on pelvis with but up and elbow pointing toward pelvis is called what?
Malpresentation
Presentation, part that enters the pelvis first is called what?
Fetal position
