NU 404 Unit 4 Exam Questions and Answers| New Update with 100% Correct Answers
Factors influencing the onset of labor -uterine stretch
-progesterone withdrawal
-increased oxytocin sensitivity
-increased release of prostaglandins
Premonitory signs of labor -Cervical changes (softening, dilation)
-Lightening (presenting part descends into pelvis)
-Increased energy level (nesting)
-Bloody show (pink tinged secretions)
-Braxton Hicks (irregular-don't increase frequency or intensity)
-Rupture of membranes (loss of amniotic fluid)
False Labor- Contractions Irregular, stops when walking, felt in back of abdomen, often
stops with comfort measures
False Labor- Cervix Soft, no dilation, no bloody show, in posterior position
False Labor- Fetus presenting part is not engaged in pelvis
True Labor- Contractions Regular, more intense when walking, continues despite comfort
measures
True Labor- Cervis Progressive changes (softening, effacement, dilation), moves to anterior
position (baby's head facing mom's back)
True Labor- Fetus Presenting part is engaged in pelvis, baby has "dropped", presenting part
presses downwad and compresses bladder
, 5 P's that affect process of labor and birth Passenger, Passageway, Powers, Position,
Psychological
Passenger (Fetus and Placenta) -fetal skull (size)
-Fetal attitude (degree of body flexion_
-Fetal lie (maternal spine to fetal spine)
-Fetal presentation (part of fetus entering pelvis)
-Fetal position (relationship of presenting part to maternal pelvic inlet)
-Fetal station (measurement of fetal descent in cm)
-Fetal engagement (entrance of fetal head into maternal pelvis)
Fetal Skull Anterior fontanelle: front of head, diamond shape
Posterior fontanelle: back of fetal head, triangular shaped
Attitude (ideal) We want babies chin flexed to chest; extremities flexed into torso
Flexed head can measure _______ cm smaller than the same baby's head extended 2
Lie (ideal) Fetus' spine runs parallel to mother's spine
Position (ideal) LOA (left occiput anterior)
Cephalic (vertex)
Military
