frequent urination, enlarging uterus, syncope, nausea, fatigue)
o Probable-changes observed by examiner (pregnancy HCG test, braxton hicks
contractions, chadwick sign, hegar sign, goodell sign, ballottement sign)
o Positive-signs attributable ONLY to the presence of a fetus (ultrasound, fetal heart
tones)
Nutrition during pregnancy & sources of nutrients: iron, carbs, protein, calcium
Iron Maternal hemoglobin formation
Liver, meats, whole grain or enriched
breads and cereals, dark green leafy
vegetables, legumes, dried fruits
Carbs Primary source of energy
Whole (fruits, vegetables, whole food
grains) instead of processed food
Protein Growth of maternal tissue and
expansion of blood volume; Secretion
of milk protein during lactation
Meats, eggs, cheese, yogurt, legumes,
nuts, grains
Calcium Maintenance of maternal bone and
tooth mineralization
Milk, cheese, yogurt, sardines or other
fish eaten with bones in, dark greenleafy vegetables except spinach or
swiss chard, calcium-set tofu, baked
beans, tortillas
Hormonal influences during pregnancy
Hormone Source Effects of changes during
pregnancy
hCG Fertilized ovum and chorionic villi Maintains corpus luteum
production of estrogen and
progesterone until the placenta
takes over the function
Progesterone Corpus luteum until 6-10 weeks of
gestation, then the placenta
Suppresses secretion of FSH and LH
by the anterior pituitary; Maintains
pregnancy by relaxing smooth
muscles, decreasing uterine
contractility; causes fat to deposit
in subcutaneous tissue over the
maternal abdomen, back, and
upper thighs; decreases mothers
ability to use insulin
Estrogen Corpus luteum until 6-10 weeks of
gestation, then the placenta
Suppresses secretion of FSH and LH
by the anterior pituitary gland;
causes fat to deposit in
subcutaneous tissues over the
maternal abdomen, back, and
upper thighs; promotes
enlargement of genitals, uterus,
and breasts; increases vascularity;
relaxes pelvic ligaments and joints;
interferes with folic acid
metabolism; increases the level of
total body proteins; promotes
retention of sodium and water;
decreases secretion of hydrochloric
acid and pepsin; decreases
mother’s ability to use insulin
Serum prolactin Anterior pituitary gland Prepares breasts for lactation
Oxytocin Posterior pituitary gland Stimulates uterine contractions;
stimulates milk ejection from
breasts after birth
Human chorionic
somatomammotropin
Placenta Acts as a growth hormone;
Contributes to breast
development; decreases maternal
metabolism of glucose; increases
the amount of fatty acids for
metabolic needs
T3 and T4 Thyroid gland Increase in thyroid hormones
supports maternal metabolism and
fetal growth and development
Parathyroid Parathyroid glands Controls calcium and magnesium
metabolismInsulin Pancreas Increases production of insulin to
compensate for insulin antagonism
caused by placental hormones;
effect of insulin antagonist is to
decrease tissue sensitivity to insulin
or ability to use insulin
Cortisol Adrenal glands Stimulates production of insulin;
increases peripheral resistance to
insulin
Aldosterone Adrenal glands Stimulates reabsorption of excess
sodium from the renal tubules
Fundal height progression
The expectation is that after week 24 of pregnancy the fundal height for a normally growing baby will
match the number of weeks of pregnancy — plus or minus 2 centimeters. For example, if you're 27
weeks pregnant, your health care provider would expect your fundal height to be about 27 centimeters.
EDD calculation: Nagele’s rule
o Nagele’s rule
o Determine first day of LMP (last menstrual period), subtract 3 months, add 7
days plus 1 year
o Alternatively, add 7 days to LMP and count forward 9 months
o Most women give birth from 7 days before to 7 days after due date
A&P of pregnancy-structure and functions
Pregnancy:
Spans 9 months
o 10 lunar months of 28 days (280 days total)
Trimesters
o First: week 1 through 13
o Second: weeks 14 through 26
o Third: weeks 27 through 40
Total term pregnancy = 37-42 weeks
Diagnosis of Pregnancy:
Early detector: HCG-Human chorionic gonadotropin
o Detect as early as 7 days after conception
o Gradually increases and peaks at 60-70 days then remains stable until 30 weeks
o Detect in serum and urine (first morning void is best)
o ELISA technology is how most home pregnancy tests work
Diagnostic testing during pregnancy: NST, CST, BPP, GBS, Glucose tolerance test
Nonstress test (fetal activity determination)
o reactive NST at least 2 15-bpm FHR accelerations lasting 15 seconds or more with fetal
movements over 20 minutes (over 32 weeks gestation)
o nonreactive NST
reactive criteria not demonstrated or met
o unsatisfactory NST
inadequate external monitor tracing of FHR
Vibroacoustic stimulation
o Variability with sound/vibration applied to abdomen
Contraction stress test (CST)
o Evaluate fetal response to stress
o Have to be having contractions and ready for labor
Nipple stimulation (releases oxytocin)
Give oxytocin via IV (so you can stop the infusion at any time)
o A (-) contraction stress test is what we want to see
o Indicated for pregnancies at risk for placental insufficiency or fetal compromise as a
result of
IUGR
diabetes mellitus
Post term or 42 week’s gestation or more
nonreactive NST
abnormal or suspicious BPP
Biophysical Profile:
Assess fetus at risk for intrauterine compromise
Used to assess fetal wellbeing
Assessment of 5 fetal variables
o breathing movement (the lungs are practicing by taking fluid in & out of the lungs)
o body movement
o Tone
o amniotic fluid volume
o FHR reactivity-non stress testing
Indications for testing
o decreased fetal movement with subsequent non-reactive NST
o management of IUGR
o preterm, diabetic, and post term pregnancies
o PROM-early dx of fetal infection
Group B Streptococcus (GBS):
Common normal flora of GI tract
o 1 in 4 women have GBS in the vagina
Leading cause of infection in the newborn
o Respiratory (most frequent), meningitis, sepsis
o Prematurity increases this risk
Testing routinely done between 35-37 weeks
o Vaginal swab, 3 day culture
o Results valid for 5 weeks
o Rapid test available for unknown status in labor, 75 minutes
Prophylactic antibiotics: 4 hours prior to delivery (to decrease bacteria in the vaginal tract)o Ampicillin or cephalexin

Monitor newborn for s/s of resp infection
Glucose Tolerance Test:
The oral glucose tolerance test is administered after an overnight fast and at least 3 days of
unrestricted diet (at least 150g of carbohydrates) and physical activity
The woman is instructed to avoid caffeine because it increases glucose levels and to abstain
from smoking for 12 hours before the test
The 3 hour OGTT requires a fasting blood glucose level, which is drawn before giving a 100-g
glucose load
Blood glucose levels are then drawn 1, 2, and 3 hours later
The woman is diagnosed with GDM if 2 or more values are met or exceeded
Body changes during pregnancy
Changes to the Uterus:
Changes in size, shape, and position
o Hegar sign- The softening of the lower uterine segment; Allows the uterus to go forward
on the bladder
o By 10 weeks, the uterus is about the size of an orange
o After 12 weeks, the uterus starts to get bigger due to the growing fetus
Changes in contractility
o Braxton Hicks sign- “Practice contractions”; Women will feel the uterus tighten up, but it
should not be painful; Tend to get more frequent closer to the delivery time
Uteroplacental blood flow
o Uterine souffle- Sounds made by the uterine arteries (should be same as uterine pulse)
o Funic souffle- Sounds made by the umbilical vessels (should be the same as the baby’s
HR)
Cervical changes
o Goodell sign- A softening of the cervix; Makes it more friable
Other changes
o Ballottement- If you push on the cervix, you can feel the baby
bouncing under your hand
o Quickening-first recognition of fetal movement
14 to 16 weeks for multiples
18-20 weeks for primips
Lightning- The baby takes pressure off and starts to descend (which is why the
baby is lower @40 weeks than 36 weeks)
Vaginal and Breast Changes:
Vagina and vulva
o Increased vascularity to the area; Can cause the cervix to change
color
o Chadwick sign: violet color to cervix & mucosa (probable sign)
o Leukorrhea: white vaginal discharge
o Mucous plug formation; Discharged prior to labor Breasts
o Fullness, increased sensitivity
o Nipples and areola become larger and more pigmented
o Increased vascularity
o Montgomery’s tubercles: hypertrophied sebaceous glands; more developed on the
areola (help lubricate things for breastfeeding)
o Mammary glands grow during 2-3 trimester
o Colostrum: early as 16 weeks for some
General System Changes:
Cardiovascular system
o Blood pressure: supine hypotension (baby blocks vessels when the mom is laying)
o Blood volume and composition: increases by 30-50%; Will look like anemia; Low
hematocrit
o Cardiac output: increased workload due to blood volume increase
o Coagulation: increased ability to coagulate
Respiratory system
o Diaphragm gets displaced as the baby grows; SOB
o Increased estrogen increases vascularity
o Pulmonary function: nasal congestion & bleeding, voice changes, dyspnea at rest
Renal system
o Anatomic changes: ureters and renal pelvis dilate, increase urine storing in bladder, UTI
o Less tubular reabsorption of glucose; Increased volume so glucose goes into the urine
o Functional changes: GFR increases, some glucose & protein in urine
o Fluid and electrolyte balance
Basal metabolism rate increases: mom gets her own private summer! (makes mother hot)
Integumentary system
o Chloasma or Melasma- Mask of pregnancy (hyperpigmentation); tends to fade after
delivery
o Linea nigra- Pigmented line that starts at the pubic area and grows up to the umbilicus
o Striae gravidarum- Stretch marks
o Palmar erythema- Color change in the palm of hand
o Gum hypertrophy- Bleeding gums
o Acne, nails, oily skin
Musculoskeletal system
o As the baby gets bigger, the mom may experience lordosis (curving inward of the lower
back)
Neurologic system
o Increased vascularity and estrogen can cause carpal tunnel syndrome (edema around
the nerves)
Gastrointestinal system
o Appetite- Pica (craving non-food items; clay, flour, cornstarch), weight gain (25-35 lbs.)
o Mouth
Bleeding gums
Excessive salivationo Esophagus, stomach, and intestines

Preeclampsia:
Pregnancy-specific syndrome
The mom’s body is acting in an immune antigen kind of way
Often occurs with first pregnancy or first pregnancy with a new partner
Hypertension develops after 20 weeks of gestation in previously normotensive woman or new
onset of proteinuria in hypertensive woman
Proteinuria (≥1+) & pathologic edema
Reduced organ perfusion & vasospasm
Etiology
o Signs and symptoms develop only during pregnancy-cure is delivery of infant
o Associated high risk factors: primigravida, primipaternity, multifetal pregnancy, morbid
obesity, 35 y/o, diabetes, kidney dz, AA, chronic HTN, previous preeclampsia
Pathophysiology-Differs from chronic hypertension
o Main pathogenic factor is not increase in BP but poor perfusion resulting from
vasospasm
o Arteriolar vasospasm diminishes diameter of blood vessels, which impedes blood flow
to all organs and increases BP
o Function in placenta, kidneys, liver, and brain depressed as much as 40% to 60%o Delivery of placenta is the cure-so patho is thought to be closely linked to placenta
o Baby is not going to grow as they should because they are not getting enough nutrients
Causes ischemia and sends off toxins - Organ damage in mom
Mild Preeclampsia:

5 Ps of labor
The 5 P’s of Labor:
Passageway
Passenger
Powers
Position of the mother
Psychological response
Passageway: Pelvic Divisions:
False Pelvis: above brim (not indicative of pelvic adequacy)
True Pelvis: Measurement of pelvic adequacy
o Pelvic inlet: upper margin of pubic bone
o Midpelvis: short anterior wall; long curved posterior wall
o Pelvic outlet: formed by ischial tuberosities laterally
Passageway: Considerations:
Pelvis Shapes
o Gynecoid-classic female type
o Android-resembles male pelvis (heart)
o Anthropoid (oval)
o Platypelloid (sideways oval)
inlet: anterior/posterior-from symphysis pubis to spine midplane: symphysis to coccyx-normally the largest plane
outlet: transverse diameter-distance between ischial spines
Passenger: Fetal Head:
Composed of bony parts that either hinder or facilitate childbirth
Key influential variables
o Sutures
o Fontanelles
Anterior
Posterior
o Molding
o Overriding sutures
Passenger Fetal Lie:
Fetal lie – relationship of cephalocaudal axis of fetus to
cephalocaudal axis of the mother
2 types
o longitudinal lie – fetal cephalocaudal axis is parallel to the
mother’s cephalocaudal axis
o transverse lie – fetal cephalocaudal axis is at right angle (90
degrees) to mother’s cephalocaudal axis
Passenger: Fetal Attitude:
Fetal attitude – relation of fetal parts to one another
o expected fetal attitude is flexion
o flexion of head/chin-to-chest, arms folded across the chest, and legs flexed up onto the
abdomen
o deviations especially related to the head will present larger diameters of the head for
the pelvisPassenger: Fetal Presentation:
Presenting part: what is it?
o determined by fetal lie, fetal attitude
Station
o Fetal station refers to how far a baby's head has descended into your
pelvis
Engagement
o Engagement of the fetal head occurs when the widest part has passed
through the pelvic inlet
Types of presentations
o Cephalic or Vertex: 95%
o Breech: frank, complete, footling
o Shoulder: transverse lie
Passenger: Fetal Position:
Fetal position – relationship of fetal presenting part to 1 of the 4 quadrants of the maternal
pelvis i.e. front (anterior), back (posterior), or sides (right or left)
o Most common fetal position is occipitoanterior
o 3 notations used to describe fetal position
right (R) or left (L) side of maternal pelvis
landmark of fetal presenting part (occiput)
anterior (A), posterior (P), or transverse (T), depending on whether the
landmark is in the front, back, or side of the maternal pelvis
Vertex presentationsVertex Presentations:
Powers: Contractions:
Rhythmic and intermittent with periods of relaxation between contractions
o Uterine rest between contractions
Phases: increment, acme, decrement
Characteristics: frequency, duration, intensity
Primary Powers of Labor: Purpose of Uterine contractions-dilation & effacement of cervix
Effacement – the taking up, drawing up, and disappearance of internal os and cervical canal into
the uterine side walls
Dilation – widening of cervical os and cervical canal from less than a cm to approximately 10 cm
Dilation/effacement/station
2/50/-1Cervical Effacement and Dilation:
Secondary Powers:
Pushing! Contraction of maternal abdominal musculature for fetal and placenta expulsion
o Only after complete cervical dilation
o If cervix is not completely dilated, bearing down causes cervical swelling or edema,
lacerations, cervical bruising, and maternal exhaustion.
o Valsalva
The mother is asked to take a deep breath, hold the breath (closed glottis), and
push downward when uterine contraction starts
Maternal Positions:
Upright position
o Gravity assists with fetal descent
o Facilitates dilation & effacement
o Reduces pressure on major maternal structures
Lateral (side-lying)
o Increases cardiac output
o Improves perfusion to organs
o Removes pressure on major maternal structures
o Helps with back pain & facilitates counterpressure
Semi-recumbent
o HOB elevated at least 30˚
o Convenient for fetal monitoring & exams
Hands and knees
o Helps back labor
o Facilitates internal rotation of fetuso Good for OP presentation
Psychological Response:
Knowledge/preparation
Past experience
Stress response
Support
Social factors
Cultural factors
s/s of labor, true labor vs false
Lightening – “dropping,” movement, or engagement of fetus into pelvic inlet
o descent moves uterus downward and fundus away from diaphragm
o results in ability of female to breathe easier
o at same time, female may experience
leg cramps or pains
increased pelvic pressure
increased venous stasis that leads to lower extremity edema
increased urinary frequency
increased vaginal secretions resulting from congestion of vaginal mucous
membranes
Sudden burst of energy
o “nesting syndrome” – occurs approximately 24 to 48 hours prior to labor onset
Urge to clean and organize
Braxton Hicks Contractions
o irregular, intermittent contractions that occurs throughout pregnancy
o tend to disappear or stop with change in activity
o discomfort centered in abdomen
Discomfort facilitate a belief that labor is occurring
“false labor”
o cervical dilation does not occur
o Can increase in occurrence closer to term
Cervical changes
o Cervical ripening – softening of cervix
cervical rigid and firmness of pregnancy gives way to weakening and softening
of cervix so that it may stretch and dilate in order to accommodate passage of
the fetus
accomplished via enzymes (collagenase & elastase) that inhibit ability of
collagen fibers to bind
o Main sign of TRUE labor is progressive dilation & effacement of cervix
Stages of labor, cardinal movements
Cardinal Movements:
Engagemento When the biparietal diameter of the head passes the pelvic inlet, the head is said to be
engaged in the pelvic inlet. In most nulliparous pregnancies, this occurs before the onset
of active labor because the firmer abdominal muscles direct the presenting part into the
pelvis. In multiparous pregnancy in which the abdominal musculature is more relaxed,
the head often remains freely movable above the pelvic brim until labor is established.
Descent
o Refers to the progress of the presenting
part through the pelvis. It depends on at
least four forces: pressure exerted by the
amniotic fluid, direct pressure exerted by
the contracting fundus on the fetus, force
of the contraction of the maternal
diaphragm and abdominal muscles in the
second stage of labor, and extension and
straightening of the fetal body.
Flexion
o As soon as the descending head meets
resistance from the cervix, pelvic wall, or
pelvic floor, it normally flexes so the chin is
brought into closer contact with the fetal
chest. Flexion permits the smaller
suboccipitobregmatic diameter (9.5 cm)
rather than the larger diameters to
present to the outlet.
Internal rotation
o The maternal pelvic inlet is widest in the
transverse diameter; therefore, the fetal
head passes the inlet into the true pelvis in
the occipitotransverse position. The outlet
is widest in the anteroposterior diameter; for the fetus to exit, the head must rotate.
Internal rotation begins at the level of the ischial spines but is not completed until the
presenting part reaches the lower pelvis. As the occiput rotates anteriorly, the face
rotates posteriorly. With each contraction the fetal head is guided by the bony pelvis
and the muscles of the pelvic floor. Eventually, the occiput will be in the midline
beneath the pubic arch. The head is almost always rotated by the time it reaches the
pelvic floor. Both the levator ani muscles and the bony pelvis are important for
achieving anterior rotation. A previous birth injury or regional anesthesia may
compromise the function of the levator sling.
Extension
o When the fetal head reaches the perineum for birth, it is deflected anteriorly by the
perineum. The occiput passes under the lower border of the symphysis pubis first, and
then the head emerges by extension; first the occiput, then the face, and finally the
chin.
Restitution and External Rotation
o After the head is born, it rotates briefly to the position it occupies when it was engaged
in the inlet. This movement is referred to as restitution. The 45 degree turn realigns the
infant’s head with the back and shoulders. The head can then be seen to rotate further.Thus external rotation occurs as the shoulders engage and descend in maneuvers similar
to those of the head. As noted, the anterior shoulder descends first. When it reaches
the outlet, it rotates to the midline and is delivered from under the pubic arch. The
posterior shoulder is guided over the perineum until it is free of the vaginal introitus.
Expulsion
o After birth of the shoulders, the head and shoulders are lifted up toward the mother’s
pubic bone, and the trunk of the baby is born by flexing it laterally in the direction of the
symphysis pubis. When the baby has emerged completely, birth is complete, and the
second stage of labor ends.
Stages of Labor:
Stage 1- Latent Phase: 0-6 cm:
Onset of regular uterine contractions
Cervix: slow effacement & dilation
Fetal engagement & descent
May have ROM or not
Pain level and time frame varies
o Nulliparas: 20 hour average
o Multiparas: 14 hour average
o Sedation can slow progression
Wide range of emotions
Stage 1- Active Phase: 6-10 cm:
Cervical dilation
o More rapid effacement & dilation
o Multiparas more rapid dilation
Progressive fetal descent
Increased discomfort with contractions
o Pelvic pressure & urge to push with fetal descent
Nausea & vomiting common
Increased bloody show
Emotional changes
Stage 2:
Complete cervical dilation to birth of infant
o Perineum bulges, flattens, and moves anteriorly, perineum becomes thin, rectum
stretches
o Crowning-fetal head encircled by external opening of vagina (introitus)
o Duration: variable
o Cardinal movements: Allow passage of infant through the pelvis
o Cord clamping-delayed?
Stage 3:
Birth to delivery of placenta Placental separation
o uterus contracts firmly, diminishing uterine capacity and placental surface area
o signs of placental separation
globular-shaped uterus
increased fundal (top of the uterus) height in abdomen
sudden gush or trickle of blood
lengthening of umbilical cord out of vagina
Usually give Pitocin IV or IM either before or after placenta delivery
Stage 4:
Delivery of placenta to 8 hours post
Physiologic & hemodynamic readjustment
o moderate drop in blood pressure
o increased pulse pressure
o moderate tachycardia
results from
blood loss (avg. 250-500 cc)
reduced weight of uterus
redistribution of blood into venous beds
Repair of cervical or vaginal lacerations
o 1st degree: superficially disrupts mucosa
o 2nd degree: divides the perineal body (episiotomies)
o 3rd degree: tear involves anal sphincter
o 4th degree: tear involves rectal mucosa
Uterus should be contracted and midline
May experience:
o Shaking
o Urinary retention
o Increased thirst & hunger
EFM interpretation & actions needed for complications
Placement of EFM:
A. Cephalic = head down
E. BreechMonitoring Contractions:
External monitor (tocometer)
Timing
o Frequency-beginning of one contraction to beginning of next (count in minute to minute
½ increments)
o Duration-beginning of contraction to the end of same contraction (rounded to nearest
10 secs)
Strength: not reliable for external monitor (subjective)
Internal monitor (IUPC)
Timing: same as external monitor
Strength: measure Montevideo units
o Measure actual value of height of each contraction for 10 minutes & total it
o Adequate labor ~200 (anything less = inadequate labor)
o Go from baseline to peak
Tachysystole: Five contractions or more in a 10 minute period
Correlate fetal heart rate with contraction to evaluate response to labor
Fetal Heart Rate (FHR):
Baseline: range of FHR during a continuous 10-minute period of monitoring (110-160 bpm)
Baseline variability: irregular fluctuations in baseline
Accelerations: Abrupt increase in FHR
Decelerations: Abrupt decrease in FHR
Tachycardia : a rate of 160 bpm or more for 10 minutes Bradycardia : FHR less than 110 bpm for more than 10 minutes
Variability tells if the baby’s system is adequate
Baseline Variability:
Irregular fluctuations in baseline
Normal
Describe as:
o Absent
o Minimal-less than 5 bpm
o Moderate-6-25 bpm
o Marked-greater than 25 bpm
o Sinusoidal pattern-fetal hypoxiaTachycardia 160:
Can be an early sign of fetal hypoxemia
Maternal or fetal infection
Fetal anemia
Maternal hyperthyroidism
Response to drugs
Bradycardia 110:
Differentiate from decelerations
Late sign of fetal hypoxia
Drugs
Cord compression
Maternal hypothermia
Maternal hypotension
Tachysystole
o Contractions being too frequent
Accelerations:
32 weeks and older
o 15 bpm above baseline lasting 15 seconds or more
Younger than 32 weeks
o 10 bpm above baseline lasting 10 seconds or more
Prolonged: longer than 2 min, less than 10 min
Decelerations:
Variable:
o Abrupt, random
Early:
o Symmetrical & associated with contraction
o Return by end of contraction
o Expected towards the end of stage 1
Late:
o Uteroplacental insufficiency-variety of reasons
o Begins after contraction
Early Decelerations: End of contraction lines up with the end of the deceleration
Tells us that the baby is okay:
o Baby returns to baseline before end of contraction
o Moderate variability (6 bpm or more)
Late Decelerations:
When the HR does not return to baseline at the end of the contraction
Minimal variability (shows that baby is not compensating well)Variable Decelerations:
Baseline normal
Moderate variability
Women is pushing/throwing up (why contractions look like that)
Category Interpretation:
Category I (normal): strong predictor of normal fetal acid-base status, routine care, no action
needed.
Category II (indeterminant): not predictive of abnormal acid-base status, but no evidence
showing category I or III. Requires continuous surveillance and re-evaluation.
Category III (abnormal): abnormal fetal acid-base status. Needs prompt evaluation & actionVEAL CHOP:
Dilation/effacement/station
Effacement – the taking up, drawing up, and disappearance of internal os and cervical canal into
the uterine side walls
Dilation – widening of cervical os and cervical canal from less than a cm to approximately 10 cm
Station- Fetal station refers to where the presenting part is in your pelvis
ROM, PROM, PPROM
PROM & PPROM:
Premature rupture of membranes (PROM)
o Rupture of amniotic sac and leakage of amniotic fluid beginning at least 1 hour before
onset of labor at any gestational age
o Nitrazine: amniotic fluid will be higher than 6.5-alkaline
o Fern test: fluid on slide and let dry-fern pattern
o If no labor in 12 hours, usually will induce-some will wait 24 hours
o Monitor s/s of infection and fetal tolerance
Preterm premature rupture of membranes
o Membranes rupture before 37 weeks of gestation and not in labor
o Occurs in up to 25% of preterm labor cases
o Often preceded by infection
o Etiology unknown
o Diagnosed after woman complains of sudden gush or slow leak of vaginal fluid
o Care management: home vs. hospital
Complications: prolapsed cord, shoulder dystocia, previa, abruption
Prolapsed Cord:
Occurs when the cord lies below the presenting part of the fetus Contributing factors: Long cord, malpresentation (breech or transverse lie), or an unengaged
presenting part
If the presenting part does not fit snugly into the lower uterine segment, when the membranes
rupture, a sudden gush of amniotic fluid may cause the cord to be displaces downward
The cord may prolapse during amniotomy if the presenting part is high
A small fetus may not fit snugly into the lower uterine segment; as a result, cord prolapse is
more likely to occur
Shoulder Dystocia:
A condition in which the head is born, but the fetal shoulders are unable to pass through the
maternal pelvis
Results from size discrepancy between the fetal shoulders and the pelvic inlet, which may be
absolute or relative because of malposition
Risk factors: History of shoulder dystocia, maternal diabetes, and prolonged second stage of
labor
Signs that indicate shoulder dystocia: Slowing of the process of the second stage of labor and
formation of a caput succedaneum
Complications: Fracture of clavicle or humerus and unilateral brachial plexus injury
Nurse should use McRoberts maneuver (knees flexed to chest)
Placenta previa:
o Placenta implanted over cervix
o Partial or complete
o PAINLESS vaginal bleeding
o Cannot vaginally deliver
o Risks
More pregnancies (more scar tissue in the uterus)
Multiple surgeries
Fibroids
Multifetal pregnancies (twins, triplets)
Abruptio placentae (placental abruption):
o Detachment of placenta before birth of infant
o Partial or complete
o PAINFUL vaginal bleeding
Can have it without bleeding
o Causes
Trauma to the abdomen (fall, car accident)
Drug use (cocaine, marijuana)
Vacuum & forceps: use & precautions & complications
Forceps Assisted Birth:
One in which an instrument with 2 curved blades is used to assist in the birth of the fetal head Indications- Prolonged second stage of labor and the need to shorten the second stage of labor
for maternal reasons; Main indication is suspicion of fetal compromise
Complications- Vaginal or cervical lacerations, urinary retention, and hematoma formation in
the pelvic soft tissues, which can result from blood vessel damage
The infant should be assessed for bruising or abrasions at the site of the blade applications,
facial palsy resulting from pressure of the blades on the facial nerve, and subdural hematoma
Because compression of the cord between the fetal head and the forceps will cause a decrease
in FHR, FHR is assessed, and recorded before and after the application of the forceps
Forceps
o FHR monitoring is important!
o Assess for trauma after delivery
Vacuum-Assisted Birth:
A birth method involving the attachment of a vacuum cup to the fetal head, using negative
pressure to assist in the birth of the head
Used to assist birth before 34 weeks of gestation
Prerequisites for use: Informed consent, completely dilated cervix, ruptured membranes,
engaged head, vertex presentation, and no suspicion of CPD
Advantages: Ease with which the vacuum extractor can be placed and the need for less
anesthesia
Vacuum
o Preferred assistive method
o Record # of attempts and time
o Caput/cephalohematoma
o Cerebral irritation-poor feeding, listless
o Jaundice from bruising

Influences on Pain During Labor:
Physical
o Visceral pain
Uterine ischemia
Cervical changes
Uterine distention
Referred pain
o Somatic pain
Distention & pressure
Traction (on peritoneum)
Laceration
Psychosocial
o Culture
o Anxiety
o Past experience
o Preparation
o Support
o Environment
Pain Distribution in Labor:
Stage 1 Stage 2 Late stage 2
Pharmacologic Pain Management:
Type of med is situation specific
Sedatives: prolonged latent phase
Systemic analgesia: IV med, crosses placenta
o Need to know onset, duration, and peak to know if it will affect the fetus
o Opioid agonist: morphine, Fentanyl, remifentanil (Ultiva)
o Opioid agonist-antagonist: Stadol, Nubain
Inhaled anesthetic: Nitrous Oxide
Regional analgesia & anesthesia
o Blocks: local tissue, Pudendal
o Spinal anesthesia: epidural (does not affect baby unless it drops the moms BP), spinal
block (C/S) Epidural = active phase (3-4 cm)
20 minutes to take effect
General anesthesia: C/S only
Pudendal Block:
Gate-Control Theory:
How can painful stimuli be ignored?
Only limited number of sensory messages can travel nerve pathways at the same time
Distraction techniques block some of these, closing a “gate”
Engaging in activity involving the spinal cord modifies transmission as well
Cognitive work-concentration on breathing
Nonpharmacologic Methods:
Preparation: Lamaze (breathing), Bradley (partner-coached breathing), Dick-Read (taking away
fear of the unknown)
Techniques
o Relaxation, focus, breathing
o Effleurage(light touch on the abdomen) & counterpressure (putting severe pressure on
the lower back)
o Music
o Water therapy
o Massage, heat
o Others: TENS, Acupressure/puncture, hypnosis, biofeedback, aromatherapy,
intradermal water block
Positions for labor
Latent- Walk around
Active- Get in bed, get on all fours
Epidural: nursing care and assessment
Induction/augmentation, readiness for labor induction
Induction:
Cervical ripening
o Bishop score
o Chemical vs mechanical AROM
Cytotec (Misoprostol)
Oxytocin/Pitocin
Augmentation:
Active management
o AROM (amniotomy), oxytocin
Forceps: shorten 2nd stage, unable to push effectively, breech, malpresentation, arrest of
rotation
Vacuum: preferred over forceps
Other methods to stimulate contractions
Bishop Score of 8 or Higher Indicates that the Cervix is Favorable for Induction:
Chemical Induction Methods:
Mechanical Induction Methods:Meds: Fentanyl, Stadol, Pitocin, Methergine, Hemabate, Misoprostol, Nubain, Betamethasone,
Magnesium Sulfate, Terbutaline, nifedipine, indomethacin
Medications Action Why used in L&D
Misoprostol (Cytotec) Binds to myometrial
cells causing strong
contractions and
ultimately resulting
in the expulsion of
tissue
For the induction of labor
and cervical ripening ;
Abortion
Oxytocin (Pitocin) (IV,
IM)
Increases the
amplitude and
frequency of uterine
contractions, which
transiently impede
uterine blood flow
and decrease
cervical activity,
causing dilation and
effacement of the
cervix
Increases uterine activity
and stimulates childbirth
Postpartum uterine
bleeding (hemorrhage)
Abortion
Nifedipine (Procardia) Inhibits the entry of
calcium ions by
blocking these
voltage-dependent
L-type calcium
channels in vascular
smooth muscle and
Prolongation of pregnancy

maturitymyocardial cells
Nubain Agonist-antagonist
analgesic that
stimulates kappa
opioid receptors
and blocks or
weakly stimulates
mu opioid
receptors, resulting
in good analgesia
but with less
respiratory
depression and
nausea and
vomiting when
compared to opioid
agonists.
Moderate to severe labor
pain and post operative
pain after c-section
Stadol Mixed agonistantagonist analgesic
that stimulates
kappa opioid
receptors and
blocks or weakly
stimulates mu
opioid receptors,
resulting in good
analgesia but with
less respiratory
depression and N/V
when compared
with opioids
Moderate to severe labor
pain and postoperative pain
after cesarean birth
Methergine This medicine works
by acting directly on
the smooth muscles
of the uterus and
prevents bleeding
after giving birth.
To prevent and control
bleeding from the uterus
that can happen after
childbirth
Hemabate Oxytocic
medications have
the effects of
oxytocin, which
causes contractions
during labor and
controls bleeding
after childbirth.
Carboprost works
on prostaglandin F
receptor sites in
Hemabate is used to treat
severe bleeding after
childbirth (postpartum).
Hemabate is also used to
produce an abortion by
causing uterine contractionsuterine muscle to
increase
contractions and
induce labor.
Magnesium Sulfate Blocks
neuromuscular
transmission and
decreases the
amount of
acetylcholine
liberated at the end
plate by the motor
nerve impulse
Used to stop preterm labor
For women with preeclampsia
First-line management of an
eclamptic seizure First-line
treatment of any seizure
during pregnancy
Neuroprotection of preterm
infants
Betamethosone It works by
activating natural
substances in the
skin to reduce
swelling, redness,
and itching
Betamethasone and
dexamethasone are the
most widely studied
corticosteroids, and they
generally have been
preferred for antenatal
treatment to accelerate
fetal organ maturation
Indomethacin It works by
inhibiting the
production of
prostaglandins,
which normally
induce contractions
Indomethacin can reduce
the number and frequency
of contractions
Terbutaline Produces relaxation
of smooth muscle
found in bronchial,
vascular and uterine
tissues
Stop or prevent premature
labor (stops contractions)
Fentanyl Opioid agonist

Newborn reflexes: how to elicit them
Root, Suck, & Swallow
Extrusion: When your baby pushes solid food out of their mouth using their tongue
Grasp: palmar & plantar
Tonic neck (fencing): This reflex occurs when the side of the infant's spine is stroked or tapped
while the infant lies on the stomach. The infant will twitch their hips toward the touch in a
dancing movement. Moro (startle): The Moro reflex is a normal reflex for an infant when he or she is startled or feels
like they are falling
Stepping: This reflex is also called the walking or dance reflex because a baby appears to take
steps or dance when held upright with their feet touching a solid surface
Babinski: The Babinski reflex occurs after the sole of the foot has been firmly stroked. The big
toe then moves upward or toward the top surface of the foot. The other toes fan out
Newborn assessment parameters: normal and normal variants
Physical assessment
o Vital signs/weight/measurements
Temperature. Able to maintain a stable body temperature of 97°F to 98.6°F
(36.5-37.5 celcius) in a normal room environment.
Heartbeat. Normally 120 to 160 beats per minute. It may be much slower when
an infant sleeps.
Breathing rate. Normally 30 to 60 breaths per minute.
Blood pressure. Normally an upper number (systolic) between 60 and 80, and a
lower number (diastolic) between 45 and 50.
Oxygen saturation. Normally 95% to 100% on room air.
o Gestational age assessment
o Skin
Color, texture, nails, presence of rashes
o Head and Face
Appearance, shape, and shaping of the head from passage through the birth
canal (molding)
The open soft spots between the bones of the baby's skull (fontanels)
Bones across the upper chest (clavicles)
Eyes, ears, nose, cheeks. Presence of red reflex in the eyes
o Chest/Abdomen/Genitalia/Anus/Elimination
Abdomen. Presence of masses or hernias.
Genitals and anus. Open passage for urine and stool and normally formed male
and female genitals.
Heart sounds and femoral (in the groin) pulses
Lungs. Breath sounds, breathing pattern.
o Extremities & Spine
o Neuro
Tone, neonatal reflexes are assessed
Newborn nutrition & breastfeeding basics: ensuring adequate feeding, stool characteristics
Infant’s output
o As the volume of breast milk increases, urine becomes dilute and should be light yellow
o Infants should have 6-8 sufficiently wet diapers every 24 hours after day 4
o Baby should not be passing meconium after day 3-4
o Infants should have at least 3 stools per day in the first month
Breastfeeding basics
o Breastfed babies should eat 8-12 times in a 24 hour periodo Parents need to awaken the baby to feed at least every 3 hours during the day and
every 4 hours at night
o Infants should be fed whenever they exhibit feeding cues, alerting the parent that they
want to feed
Stool characteristics
o Meconium followed by transitional and soft and yellow stool
The first stool your baby passes is thick, greenish black, and sticky. It's called meconium. The
stools usually change from this thick, greenish black to green in the first few days. They'll change
to yellow or yellowish brown by the end of the first week.
Jaundice: physiologic & pathologic; kernicterus
Physiologic Jaundice:
Occurs in 60% of newborns
Causes: increased bilirubin production, short RBC lifespan, & immature liver
Begins after 24 hours of age
Cephalocaudal distribution-blanching-sclera
Kernicterus-results from bilirubin 20 to 25
Early & frequent feedings help decrease bili
Pathologic Jaundice:
Bilirubin can accumulate to hazardous levels and lead to a pathologic condition
Unconjugated hyperbilirubinemia that is either pathologic in origin or severe enough to warrant
further evaluation and treatment
Jaundice is usually considered pathologic if it appears within 24 hours after birth, TSB levels
increase by more than 0.2, TSB is greater than the 95th percentile for age in hours, direct serum
bilirubin levels exceed 1.5-2, or clinical jaundice lasts more than 2 weeks
Kernicterus:
Kernicterus, or bilirubin encephalopathy, is bilirubin-induced neurological damage,
which is most commonly seen in infants. It occurs when the unconjugated bilirubin
(indirect bilirubin) levels cross 25 mg/dL in the blood from any event leading to
decreased elimination and increased production of bilirubin.
S/S: Poor feeding, irritability, no startle reflex, high pitched cry, lethargy, brief pauses in
breathing, floppy muscles
Rh incompatibility & RhoGAM vs. ABO incompatibility
Rh Incompatibility:
When the mother is Rh negative and the fetus is Rh positive
Typically has no effect during the first pregnancy because the sensitization to Rh antigens rarely
occurs before the onset of labor
Can be treated with fetal blood transfusions or IVIg
Can be prevented with RhoGAM
ABO: When the major blood group antigens of the fetus are different than those of the mothers
Naturally occurring anti-A or anti-B antibodies already present in the maternal circulation
crosses the placenta and attack the fetal RBC’s, causing hemolysis
Jaundice may appear shortly after birth
Treatment = phototherapy and exchange transfusions
Pre-term & Post-term newborn characteristics & related issues
Post term:
Creases on feet
Sparse vernix/lanugo
Long nails
Abundant scalp hair
Cracked, peeling skin
Wasted physical appearance that reflects placental insufficiency
Depletion of subcutaneous fat gives them a thin, elongated appearance
The scant amounts of vernix in the skinfolds may be stained green or yellow (meconium in
amniotic fluid)
Increase in fetal mortality
Preterm:
Increased risk for morbidity and mortality
Higher risk for hypoglycemia
Respiratory distress syndrome
Transient apnea of the newborn
Greater likelihood of NICU admission
Terminology: IUGR, SGA, LGA, LBW, VLBW, ELBW
IUGR: Found in infants whose uterine growth is restricted
Macrosomia: A baby who is diagnosed as having fetal macrosomia weighs more than 8
pounds, 13 ounces (4,000 grams), regardless of his or her gestational age
SGA: Small for gestational age- An infant whose rate of intrauterine growth was slowed
and whose birth weight falls below the 10th percentile on intrauterine growth curves
LGA: Large for gestational age - Infant whose birth weight falls above the 90th percentile
on intrauterine growth charts
LBW: Low birth weight - Infant whose birth weight is less than 2500g (5 lbs, 8 oz)
regardless of gestational age
VLBW: Very low birth weight - Infant whose birth weight is less than 1500 g (3 lbs, 5 oz)
ELBW: Extremely low birth weight- Infant whose birth weight is less than 1000 g (2 lb 3
oz)
NOWS: s/s, treatment, assessment S/S: crying, irritable, not sleeping, watery stools, not eating well, etc. Watch for dehydration b/c
don’t feed well & diarrhea.
Treatment: - Medication, eat, sleep, console, limit stimulation, promote rooming in
Cold stress with NB and preemies
When the neonate’s temperature drops, in response to norepinephrine release,
vasoconstriction occurs as a mechanism to conserve heat
The infant can appear cool and mottled; the skin will feel cool especially in extremities
If the hypothermia is not corrected, it will progress to cold stress, which imposes metabolic and
physiologic demands on all infants, regardless of gestational age and condition
The respiratory rate increases in response to the increased need for oxygen
When an infant is stressed by cold, oxygen consumption increases, and pulmonary and
peripheral vasoconstriction occur, thereby decreasing oxygen uptake by the lungs and oxygen to
the tissues; anaerobic glycolysis increases, and there is a decrease in PO2 and pH, leading to
metabolic acidosis
s/s of newborn resp distress
Nasal flaring, retractions, stridor, gasping, grunting, tachypnea
Newborn diagnostic tests: Newborn screen, hearing screen, bili, blood glucose
Newborn Tests:
Bilirubin
o Routine before discharge or if baby looks jaundiced
o You will hear TCB and TSB- TCB is Transcutaneous and TSB is Total Serum- TSB is more
accurate
Newborn screening
o PKU, hypothyroidism, others vary by state
o Done after 24 hours old & at least one feeding
Hearing Screen
o 30 states require it-most hospitals do it routinely
o Repeat @ 2-8 weeks i
