Maternal & Newborn Nursing Unit 2
Presumptive Signs Amenorrhea: no menses Nausea: 4 – 12th week Breast changes Urinary frequency ------------------------------------------------------------ Quickening: 1st movements felt; 16-20 wks. Fatigue & drowsiness Pigmentation Abdomen = lineanigra: dark line from umbilicus to symphysis Face = chloasma: blotchy, suntanned mask
Probable Signs Abdomen enlargement Chadwick sign Bluish / purplish discoloration to vulva & vagina by ↑ blood supply 4th week Goodell’s sign Softening of cervix Hegar’s sign Softening of lower uterine segment 6th week
Probable Signs Ballottement Rebounding of fetus against Dr.’s fingers after made it move 4-5th month Braxton Hicks contractions Uterine contractions occurring @ 5-10 minute intervals throughout pregnancy Usually not noticed until end of pregnancy Fetal outline Abdominal striae Pregnancy tests Based on HCG; (+) 10 days after missed period
Positive Signs Fetal heartbeat 10 weeks by doppler Fetal movements After 5th month while in supine position Ultrasound As early as 4th week; very accurate after 3rd month
Expected Date of Delivery Count backwards 3 months from 1st day of last menstrual period Add 7 days Change year as needed
Prenatal Assessment - History • Obstetric • Menstrual • Contraceptive • Medical & surgical • Family history • Woman’s & partner’s health • Psychosocial
Prenatal Visits Conception – 28 weeks Every 4 weeks 29 – 36 weeks Every 2 - 3 weeks 37 weeks to birth Weekly
Prenatal Assessments - Physicals Review known risk factors & assess new VS same arm & same position Weight UA for protein, glucose, & ketones Glucose screening @ 24-28 weeks Fundal height Leopold’s maneuvers: assess presentation & position of fetus Fetal heart rate: 120 – 160 bpm Electronic doppler by 10 weeks Review nutrition Assess discomforts or problems since last visit
Amniocentesis Transabdominal needle aspiration of 10-20mL amniotic fld. for lab analysis Prep Signed consent form Void prior to test Purposes Determine fetal age & maturity Determine Alpha-Fetoprotein (AFP) levels Measure estriol levels & fetal thyroid hormone
Post Amniocentesis Monitor FHR & maternal VS q 15 Position on L. side to counteract supine hypotension Instruct to call MD if Leakage of serous vaginal fld. Fetal hyperactivity or unusual fetal lethargy
Ultrasound High frequency sound waves to detect FHR, placental location or body parts Purposes Measure size of internal structures Identify pregnancy Detection Fetal maturity Prep Drink fluids Do NOT empty bladder prior
Non-stress Test Evaluate FHR accelerations that normally occur to fetal activity Prep L. side semi-fowler’s position Evaluate FHR immediately following activity Monitor Mother’s BP & uterine activity Interpretation + test (good) = FHR ↑ 15 bpm above baseline in response to fetal activity - test (bad) = FHR does not ↑ with fetal movements
Oxytocin Challenge Test / Contraction Stress Test Assess FHR to contractions & efficiency of respiratory function of placenta Prep Left side & on monitor Oxytocin infusion or nipple stimulation Interpretation - test = 3 contractions of good quality & duration without late responses of FHR = adequate placenta + test = late responses of FHR = placental insufficiency
Cardiac & Respiratory Changes Blood vol. ↑ 45% BP remains about same as pre-pregnancy but P & R ↑ Heart & lungs gradually displaced upward
Digestive System Changes Stomach & intestines displaced upward ↓ tone & motility of tract ↓ HCl acid & pepsin secretions Digestive process slows
Endocrine Changes Glands ↑ in size & activity Metabolism rate ↑
Reproductive Changes Breast blood vessels & secreting glands enlarge Uterus ↑ in size, cervix softens Vaginal mucosa thickens Leukorrhea - ↑ vaginal discharge
Psychosocial Changes 1st trimester Self-centered & concerned with own adjustment to idea of pregnancy Have feelings of ambivalence 2nd trimester More tranquil, @ ease Reality now recognized, come to accept pregnant state Third trimester Increased vulnerability & dependence Labile mood
Promoting Health - Nutrition Nutrient intake = needs of mother & fetus ↑ caloric intake by 300 calories ↑ Vitamin A, C, D & folic acid Wt. reduction programs discouraged Wt. gain up to 4.4 lbs for 1st trimester & 1 lb/wk Normal weight = 25-35 lbs.
