*DRUGS TO AVOID IN THIRD TRIMESTER?*
********NSAIDs (eg. Ibuprofen) - RISK of premature closure of Fetal Ductus Arteriosus
Nagele's Rule
- 3 months, + 7 days & 1 year from FIRST DAY of LMP
8 Weeks Gestation
-ALL MAJOR ORGAN SYSTEMS ARE IN PLACE & Functioning in a simple way
TERATOGENIC DRUGS

Infants do not require more than one extra layer than adults require to be comfortable. -Breastfeed and ensure immunizations are updated.
PRIORITY:
-Signs of UTI during pregnancy (eg. urinary urgency, DYSURIA) -Signs of Pre-Term Labor (eg. intermittent lower back pain) -Signs of Pre-Eclampsia (eg. headaches) -Signs of Subinvolution (d/t UTERINE INFECTION & Retained Placental Fragment from Delivery) = risk of POST PARTUM HEMORRHAGE -Signs of FETAL TACHYCARDIA (110-160 normal range)

Umbilical Cord Prolapse
INTERVENTION: -Place patient in TRENDELENBURG position (supine with feet elevated) OR KNEE-CHEST POSITION (on hands & knees) & keep cord WARM and MOIST & attempt to push the cord back in. ***TRENDELENBURG POSITION - can increase pressure of the vena cava and result in MATERNAL HYPOTENSION (assess - pallor, perspiration) = HELP client to a sitting position; move uterus off the client's vena cava to alleviate maternal hypotension!
PRETERM LABOR
Progressive cervical dilation and/or effacement resulting from uterine contractions before term gestation (before 37 weeks) INTERVENTION: -IM antenatal glucocorticoids (eg, betamethasone, dexamethasone) to stimulate fetal lung maturation and promote surfactant development -Antibiotics (eg, penicillin) to prevent group B Streptococcus infection in the newborn if preterm birth occurs *-IV Magnesium Sulfate: SEIZURE PRECAUTION* -Tocolytic medications (eg, nifedipine, indomethacin) = to suppress uterine activity -Monitoring pertinent laboratory results & *Place on continuous fetal monitoring* *X - AROM (or Amniotomy) = done to augment labor or assess amniotic fluid; CONTRAINDICATED IN PRETERM LABOR*
AMNIOCENTESIS
Removal of amniotic fluid of evaluation; can be performed as early as 15-17th weeks of pregnancy. INTERVENTION: -Ultrasound (sonogram) done prior for DETERMINATION of PLACENTAL LOCATION (position of placenta & fetus). **Reveals: Lecithin/Sphingomyelin (L/S) ratio & presence of Phosphatidylglycerol (PG); L/S ratio > 2 & + PG presence = FETAL LUNG MATURITY

LATE DECELERATIONS
Decrease in FHR that begins AFTER a contraction, reaches its lowest point (nadir) after the contraction peak, and then gradually returns to baseline. = impaired fetal oxygenation associated with decreased uteroplacental perfusion (eg, due to maternal hypotension after epidural placement or uterine tachysystole, intrauterine growth restriction, preeclampsia, diabetes). INTERVENTION: -DISCONTINUE OXYTOCIN -PUT ON LEFT-SIDE -ADMINISTER O2 via FACE MASK (8-10 L) -IV FLUID (BOLUS OF ISOTONIC FLUIDS) -NOTIFY HCP

Performed to screen for Rh sensitization; can be DIRECT (in baby) or INDIRECT (in pregnant women) eg. If an Rh-negative mother (eg, O negative blood type) is exposed to Rh-positive fetal blood (if the father is Rh positive), the pregnant client develops antibodies to the Rh antigen (ie, Rh sensitization), placing the current fetus and all future pregnancies at risk for serious complications (eg, hemolytic anemia)
