early on done for genetic testing, later done for lung maturity testing
what are three complications of amniocentesis?
spontaneous abortion
fetal injury
FACT: when amniocentesis is done in early pregnancy the bladder must be full to push uterus farther up into the abdomen
FACT: when amniocentesis is done later in pregnancy, the bladder must be empty to prevent it from being punctured.

what do you do if there is a cord prolapse?
change mom's position to knee chest to relieve pressure on cord, or push fetus off of ford and hold until c-section performed
what conditions are late decelerations associated with?
later decals indicate uteroplacental insufficiency and are associated with conditions like post maturity, preeclampsia, diabetes mellitus, cardiac disease and abrubtio placentae
FACT: a decrease in uteroplacental perfusion results in late decelerations
FACT: cord compression results in a pattern of variable decelerations
what is a non stress test?
it is used to determine fetal well being in high risk pregnancy and is useful in post maturity cases.

a healthy fetus will usually show accelerations of at least 15 beats off of baseline, lasting at least 15 seconds, occurring twice in 20 minutes time, if the fetus responds this way it is healthy and considered "reactive"

percutaneous umbilical blood sampling, done during pregnancy under ultrasound guidance.
can test for hemoglobin, clotting disorders, sepsis and genetics
what is the most important determinant of fetal maturity for extrauterine survival?
lung maturity, lung surfactant (LS) ratio of 2:1 or higher is needed.
what are the stages of labor?
there are four stages of labor:
1st: from beginning of regular contractions until 10cm dilation and 100% effacement
2nd: 10cm dilation to delivery of baby
3rd: from delivery of baby until delivery of placenta
4th: the time after delivery of placenta, approx. 2hrs recovery

transition phase:8-10cm dilation, contractions about 1.5 min apart and last 60-90 seconds duration
what is leopards maneuver?
feeling abdomen to determine fetal positioning
what stage is the baby at if it is at the level of the ischial spines of the pelvis?
stage zero…if the baby is at a (-) it is above the ischial spines, if the baby is at a (+) it is below the ischial spines and closer to being outside the body.
what is the fetal lie?
the relationship of th long axis (spine) of the baby to the long axis (spine) of the mother, it can be longitudinal, transverse or oblique (slanted).
what is the fetal attitude?
the position of the baby's parts to itself, either flexed or extended, flexion is desired.
what does the APGAR score assess?
heart rate (absent, fast, slow)
respiratory effort(no cry, weak, vigorous)
muscle tone (flaccid, slight flexed, very flexed)
reflex irritability (no response, grimace, cry or pulls away)
color (totally blue, blue extremities and pink core, totally pink)

apgar score taken at 1 and 5 minutes post delivery and again at 10 minutes if baby scores 6 or under at the five minute test.
when giving medications during labor what method is preferred and why?
IV is preferred over IM because IV is faster onset and the peak is faster and the duration of action is shorter, so less impact on baby.

IV: onset in 5 min, peak in 30 min, duration 1 hour

IM: onset in 30 min, peak 1-3 hrs, duration 4-6 hrs.
what would you do for the pt who experiences hypotension after an epidural?
immediately turn onto left side
increase IV fluids
begin O2 at 10L/min by mask
notify doc and have ephedrine ready at bedside

thicker, whitish yellowish, lasts up to act 4 weeks postpartum
when do we give rhogam?
it is given to an rh negative mother who delivers an rh positive baby and has a negative coombs test. If the mother has a positive coombs test there is no need to give rhogam because the mother is already sensitized
what are three psychosocial phases the postpartum woman experiences?
taking in: dependency behaviors in the first 2 days, mom is needy

taking hold: most receptive to teaching, begins to take care of baby and focus less on self

letting go: confident in taking care of newborn and self.
what is narcosis?
when narcotics are given late in the L&D process and they impact the baby, causing decreased respirations and hypotonia (flaccid limbs)
what can mag sulfate do to the fetus during L&D?
can cause hypermagnesemia in neonate leading to depressed respirations, hypocalcemia and hypotonia
when suctioning the neonate, what is done first?
suction the mouth first, then the nares because stimulation of nares can make the baby inhale and possibly aspirate mucus in oral pharynx.
what is the difference between caput succedaneum and cephalahematoma?
caput is edema under the scalp that crosses suture lines and is present at birth

cephalahematoma is blood under the periosteum and usually appears a few hours after birth, it does not cross suture lines. more localized and poses a greater risk for jaundice due to excess RBC breakdown
what should we note about the umbilical cord after delivery?
check to make sure it has three vessels, one vein (carrying oxygenated blood to fetus) and two arteries (carrying deoxygenated blood to placenta)

cord anomalies usually indicate cardiovascular or renal anomalies
what are the normal neonatal reflexes?
rooting, baby turns head to touch
moro, startle reflex
tonic neck, turn head and arm and leg change position
babinski, foot stroked, toes fan
palmar grasp, fingers close if touched
plantar, toes grip if touched
stepping, lift baby upright and looks like it wants to walk or step
what can heat loss end up doing to the neonate?
it leads to depletion of glucose and causes the neonate to use brown fat stores to maintain heat, this results in possible ketoacidosis and possible shock.
what is the normal serum glucose of the neonate?

if the baby's sugar is low, you may need to give little bit of glucose water, but follow with breast feeding asap because the protein and fats from the milk will keep blood sugars up and stable longer.
where do you perform heel sticks on a baby?
make a V shape with your fingers on bottom of foot, and do the stick outside the V areas, on the sides of the heel, not center.
when does physiologic jaundice occur?
occurs at 2-3 days of life and it is due to the immature liver's ability to keep up with RBC destruction and bind to blirubin.

unconjugated (unbound) bilirubin is the problem
what is pathologic jaundice and when does it occur?
it occurs before 24 hours old, or persists longer than 7 days
when is PKU screening done?
after 24 hours of ingestion of breast milk or formula.
what are the general caloric needs of the neonate?
a baby needs about 50 calories per pound of body weight or 108 calories per kilogram of body weight for the first 6 months
what are the different types of miscarriage?
threatened: spotting without cervical changes

inevitable: moderate to heavy bleeding with tissue, open cervical os

complete: all products of conception are passed, cervix closed

septic: fever, abdominal pain, foul smelling discharge, bleeding from scant to heavy

missed: fetus is dead, placenta is atrophied but products of conception have not passed. cervix closed

recurrent/habitual: loss of three or more pregnancies
what is a treatment for incompetent cervix?
cerclage, a.k.a. McDonald suture is placed around cervix to close the os. Will be removed prior to birth if vaginal birth is planned.
what is a hydatidiform mole?
when the chorionic villi degenerate into a bunch of fluid filled vesicles in grape like clusters.
an embryo is rarely present, this condition reacts like a pregnancy so the woman thinks she is pregnant but it is not viable. It may lead to cancer called choriocarcinoma
what are some symptoms and signs of hydatidaform mole?
vaginal bleeding in first trimester
size and date discrepancy, uterus is larger than expected for gestational age
excessive nausea and vomiting
abdominal cramping
early symptoms of preeclampsia
why is a woman who had a hydatidaform mole told to go on birth control for one year?
because this condition causes an increase in hcg levels and these higher levels can lead to cancer, the woman's hcg levels will be tested frequently after she has the mass removed, to make sure they go down. Since pregnancy causes increased levels she shouldn't get pregnant so that the doctor can distinguish cancer risk .
what is the difference between abruptio placentae and placenta previa?
abrupt placentae is when the placenta begins to separate or pull away from the inside of the uterus. The abdomen will be board like and the woman in extreme pain, also may have dark red bleeding

placenta pre via is painless, bright red bleeding due to the placenta being attached at the bottom of the uterus. No vaginal exams should be performed due to risk to fetus.
what is DIC?
disseminated intravascular coagulation syndrome. It is an abnormal clotting issue due to depleted clotting factors, it causes widespread external and internal bleeding.

It is related to fetal demise, infection and sepsis, pregnancy induced hypertension (preeclampsia) and abruptio placentae.
what levels of hematocrit and hemoglobin indicate anemia in the pregnant woman?
1st trimester: Hgb less than 11g/dL and Hct less than 37%

2nd trimester: Hgb less than 10.5g/dL and Hct less than 35%

3rd trimester: Hgb less than 10g/dL and Hct less than 32%

*levels are the lowest in the 3rd trimester.
what are some adverse side effects of iron supplements used to help avoid anemia during pregnancy?
gastric irritation
nausea or vomiting

REMEMBER: take iron supplements with vitamin C to increase absorption.

if taken with eggs, milk or cereal it may decrease absorption

may turn stools dark green or black
what are some common diseases to watch for during pregnancy?
chlamydia, HPV, gonorrhea, syphilis, toxoplasmosis, hepatitis, rubella, cytomegalovirus (CMV), herpes virus, HIV/AIDS, bacterial vaginosis, candida albicans yeast infections, trichomoniasis
what is toxoplasmosis caused by?
it is related to cat letterboxes, gardening and raw meat...
what if a pregnant woman has low or no rubella titers?
if the woman has not had rubella or her immunity is low, she should stay away from sick people during pregnancy and after she gives birth she should be given the rubella vaccine. Since it is a live vaccine she should not get pregnant for three months due to teratogenic effects on the fetus, but she can still breastfeed.
FACT: normal treatments for disease or STDs that are fine for the non pregnant woman may be contraindicated during pregnancy due to teratogenic effects on the fetus
FACT: adolescents need more nutrition during pregnancy since they are not fully developed themselves and they are growing another person.
what time frame is considered to be preterm labor?
the onset of labor between 20 and 37 6/7 weeks.
what things can lead to preterm labor?
diabetes, cardiac disease, preeclampsia and placenta previa, infections (especially UTI) over distention of uterus from multiple fetuses or too much fluid (hydraminos) or a large for gestational age baby
what is the antidote for magnesium sulfate?
calcium gluconate.
what are some drugs used to stop pre term labor?
tocolytic drugs:

magnesium sulfate

these drugs can relax muscles and depress the CNS so watch respirations, also, tachycardia is a major side effect of tocolytic drugs so monitor pulse prior to using.
what is dystocia?
difficult birth resulting from any cause.
what are the 5 P's of dystocia?
power (contractions)
passage (size of pelvis)
passenger (fetus or placenta)
psyche (woman's response to labor)
position (position of woman)
what are some contraindications to using pitocin?
if you know pelvis is too small to accommodate baby (cephalopelvic disproportion)
fetal stress
placenta previa
prior classical incision of uterus (top to bottom/vertical)
active genital herpes infection
floating fetus
unripe cervix
when using pitocin, use lowest port, in case you need to stop infusion quickly, less will be in the line.
women with previous uterine scars are prone to rupture, this is a medical emergency, requiring immediate surgery to save both mom and baby.
what is gestational hypertension?
BP elevation occurs for the first time after mid pregnancy

there is NO proteinuria present
what is transient hypertension?
gestational hypertension, with no other signs of preeclampsia, it is present at time of birth.
what is preeclampsia?
it usually occurs after 20 weeks gestation, it involves gestational hypertension AND protienuria.

what is chronic hypertension?
HTN that is observed before pregnancy or diagnosed before the 20th week of pregnancy
how is preeclampsia diagnosed?
it is characterized by an increase in BP of 30mmHg systolic or 15 mmHg diastolic over the previous usual baseline with other S&S of preeclampsia
what are the three classifications of preeclampsia?
eclampsia, seizures and coma
HELLP syndrome

there is no known cause of preeclampsia
what is HELLP syndrome characterized by?
elevated liver enzymes
low platelets
what are some risk factors for gestational diabetes?

recurrent (monilial) yeast infections
when is a glucose screen typically done during pregnancy?
between 24-26 weeks gestation
what is the glucose level used to determine gestational diabetes?
suspected if glucose is greater than 140 mg/dL after one hour, then a 3 hour tolerance test needs to be done.
what are a few risks of cesarean birth?
anesthesia complications
complications of abdominal surgery
injury to the urinary tract
FACT: babies that are born cesarean are not "squeezed" vaginally and therefore have more fluid left in their lungs, and are susceptible to transient tachypnea and respiratory distress.
FACT: abdominal surgery like cesarean, can cause paralytic ileus, symptoms may include absent bowel sounds and distentions, early ambulation can help.
what are some causes of post partum hemorrhage?
uterine atony
lacerations of the vagina
retained placental fragments
full bladder
high parity (lots of pregnancies)
dystocia and prolonged labor
cesarean delivery
over distention of uterus
abruptio placentae

what immediate nursing actions should be taken when there is postpartum hemorrhage?
fundal massage!!!!
notify doctor if the funds does not become firm with massage
count and weigh pads to estimate blood loss
assess and record vitals
increase IV fluids
administer oxytocin as prescribed
what might jitteriness in a newborn indicate?
it may indicate hypoglycemia, hypocalcemia or possibly drug withdrawal
When caring for the neonate, the first thing you want to address is heat loss, limit cold stress and then address the ABCs.
babies cannot shiver so if they get too cold their bodies need to compensate by burning brown fat. baby may experience tachypnea and tachycardia.
what is hyperbilirubinemia?
