Stage–>onset of labor to complete cervical dilation
First stage
Three phases of the first stage of labor
Latent
Active
Transition
Labor on set to 3 cm dilation
Latent phase (first stage)
4– 7 cm dilation
Active phase (first stage)
8–10 cm dilation
Transition (first stage)
Complete dilation to birth of baby
Second stage of labor
Birth to placental expulsion
Third stage
1–4 h after placental expulsion; uterus contracts to control bleeding
Fourth stage of labor (recovery)
Single most important factor influencing fetal well being
euglycemic status of mother
S&S of impending labor
Premonitory Signs
aka as engagement; fetus descends into pelvic inlet
Lightening
Subjective sensation
Weeks before delivery Lightening occurs in Primigravida
2-4 weeks before delivery
Lightening in Multigravida occurs
with onset of labor
Support wait a growing uterus and directs presenting part into true promise
False pelvis
top of V
There any limits of birth canal
True pelvis
Point where baby interstate true pelvis
Inlet
Female pelvis
Inlet is rounded
favorable for delivery
50%
Gynecoid pelvis
Normal female pelvis
Usually OA
Gynecoid pelvis
Male pelvis
Android pelvis
Inlet heart-shaped
Head decent into pelvis slow
Arrest of labor frequent -> C/S
Android pelvis
Android pelvis (head engages)
Head usually engages transverse or OP
Favorable influence
labor inlet is oval
Abe like pelvis
Anthropoid pelvis
Anterior fontanelle
Bregma
Relationship of fetal parts to one another (flexion/extension of fetal head)
attitude
Cephalic presentation
Fetal head first
Shoulder presentation
Transverse lie
You don’t hips are flexed, knees are extended; buttocks present. (Legs by ears)
Breech (frank) presentation

0.3g+/24h protein excrete
proteinuria
Mild pre-eclampsia
140/90+ +proteinuria

160/110+
160/110+ >15 MIN =
MEDICAL EMERG
3+ proteinuria or 5+g/ 24h
Severe Preeclampsia
Oliguria <500cc/24h Cerebral visual disturbances Pulmonary edema/ cyanosis RUQ/ Epigastric Pain Impaired Liver Function Thrombocytopenia IUGR
s/s of severe preeclampsia
New-onset grand mal seizures in woman with pre-eclampsia

Ca+ Gluconate
Must Keep at Bedside
Hour PP Risk for Seizures Continues
48h
Diuresis –>Decreased Risk
Nursing Considerations Pre-eclampsia
Close to RN Station Dark, quite, low stimuli Private L side lying Decrease Na+ Increase Protein
relative position of fetal presenting part above or below an imaginary line drawn between maternal ischial spines
Station
largest diameter of presenting part reaches or passes through pelvic inlet
Engagement
Irregular contractions
Pain in fundus, lower abd, or groin (all up front)
Easily Sedated
False Labor
Pain felt in back and radiates forward, Contractions become regular, Sedation is not effective
True Labor
Only Definitive Way to Dx Labor
Vag Exam
Reassess 1h after admit
During Stage 1 of Labor SBP
increases w/ contractions
During Stage 2 of Labor (BP)
SBP& DBP increase w/ contractions, may stay SLIGHTLY elevated btwn
During labor- GI motility, gastric emptying, blood glucose, and insulin requirements
decrease–> N/V (esp w/ transition)
Increase during labor
O2 demand/ consumption –> increased RR; Immune response –> Increased WBC
+GBS
PCN q4 x 2 doses
Pattern and intensity directly effect labor length (wavelike)
uterine contractions
Amniotic Fluid Characteristics
Clear
Alkaline
May have white flakes/ earthy odor
Natrazine Test
pH
want blue/ purple (alkaline)
MUST be before bag. lube
Green Natrazine Test
False Reading
Negative Natrazine Test
Yellow
Ferning
(ROM)Definitive
Sample placed on slide–> fern pattern
Always first intervention after ROM
Immediately assess FHR
ROM–> Temp
q1-2h before ROM (q2-4)
Hours of labor vs cervical dilation
based on prime vs multi
Labor Curve
Uterine Contractions MUST BE
validated by PALPATION
q15-30
note f,d,I, Tone
1 stage assess FHR
q15-30 min
Continuous monitoring best
2nd Stage Assess FHR

q1h (dictated by status/ meds/ induction)
Low platelets
NO EPIDURAL
Contraindications for Activity
ROM w/o engagement Faulty presentation/ fetal position Complications of preg Vaginal Bleeding Active Labor Meds
Frequent voiding prevents
distended bladder–> slows fetal descent & increases discomfort w/ contractions
Effleurage
counterclockwise
straight back
tactile stimulation/distraction
Helps w/ back ache
Breathing to prevent pushing
Panting
Ritgen’s Maneuver
push on rect. area –> lift fetal head (extend)
Suction
mouth then nose before body delivered
bladder fails to close properly during embryonic development –> fistula between the bladder and umbilicus
patent urachus
Clinical Manifestations of patent urachus
Clear odorless fluid draining from base of the cord→ph test
