Usually at uterine fundus Chorionic villi—fingerlike projections from the trophoblasts that extend into maternal blood vessels of deciduas. Place of oxygen & nutrition and waste exchange Ovum stage (<14) –from cellular replication (morula), blastocyst formation, and differentiation into three primary germ layers (endoder/ entoderm, mesoderm, ectoderm) Embryo stage (day 15 to 8 wks)—most critical for development, greatest risk from teratogens. Women should avoid lg groups of people to limit exposure to infections, Handwashing important Layers of Embryo: Endoderm/entoderm: inner most layer of cells that become internal organs (such as intestines), epithelium of respiratory tract and other organs Mesoderm: middle layer that becomes CT, bone marrow, muscles, blood, lymph tissue, epithelial tissue, bones/teeth Ectoderm: outer layer that develops into skin, nails, glands, CNS, PNS (peripheral NS) Fetal Stage: (9wks to birth) viability possible >500g and 20 weeks, good chance viability >32 wks.

Pelvic joints relax. Gastrointestional- N/V (may be hormonal, or increased pressure of stomach / intestines) Renal- GFR increases; urinary frequency is common Endocrine-placenta an endocrine organ- (hCG, progesterone, estrogen, etc) to maintain preg. Serum & Urine Pregnancy tests—presence of hCG(human chorionic gonadotropin) earliest biochemical marker for preg. (6-11 days in blood ; 26 days in urine) after conception following implantation; --hCG begins w/implantation and peaks 60-70 days gestation, then declines until 140 days, then increases until term. --Higher hCG levels indicate multifetal preg., ectopic preg, hydatidiform mole (gestational trophoblastic disease) or abnormal gestation such as Down syndrome. --Slow increases or abnormal decreases may indicate threatened abortion --Some meds may cause false + or — preg. results (anticonvulsants, diuretics, tranquilizers) --urine samples should be first-voided moring specimens Expected Vital signs Blood pressure: same as prepreg. range 1st trimester and after 20 weeks. 5-10mmHg during 2nd trimester.

It includes language, communication style, traditiosn, religions, art, music, dress, health beliefs, and heal practices Ethnicity: bond or kinship a person feels with his or her country of birth or place of ancestral origin. It exists regardless of whether or not a person has ever lived outside the US Eliminating acultural nursing care: (care that avoids concern for cultural differences) It is the traditional tendency to treat all clts as though no cultgural differences exist. Culturally sensitive nursing: incorporates a client's cultural preferences into the prenatal care situation as much as possible. It respects and is compatible with clt's culture and shows respect for the values and beliefs of others. Predominant culture is Anglicized or English-based. Freely express positive and neg. feelings; Prefer direct eye contact, address people in a casual manner; prefer a strong handshake; include fathers in childbirth classes, labor, and birth. Native American—Indian nations found in N. America including Eskimos and Aleuts Generally private, hesitate in sharing personal info, consider impatience disrespectful.; believe that no person has the right to speak for another; lingering eye contact is an invasion of privacy and disrespectful; may prefer a light passing of the hands vs strong handshake; stoicism during birth is encouraged; father may be absent from birth; female family & friends attend birth; may want the placent returned. African American—ancestral origin in Africa Hesitate to give more info than asked for; communication style is frequently loud and animated with lots of body movement; comfortable with close personal space with family/friends; expressions of pain are usually open and public; fathers and female attendants during labor and delivery. Latinos—ethnic origins from Latin or So. America Comfortable sitting close to interviewers; "evil eye" (bad omen or curse) can be given to child if the child is admired and the admirer does not touch the child; eye contact is attentive and respectful; prolonged staring is confrontational & intimidating; men are protective and authoritarian to women and children and expect to be consulted in decision making; latino fathers may not prefer to play an active role in labor & birthing process (prefer to observe or wait outside); generally vocal and active during labor; prefer to keep their body covered. Asian Americans—descend from China, Japan, Korea, Philippiines, Thailand, Cambodia, Laos, Vietnam Respond with brief factual answers; do not openly disagree with authority figures; prolonged lingering eye contact is invasion of privacy and disrespectful; prefer > an arms length distance away; head should be touched only by close relatives; area between woman's waist and knee is especially private (not to be touched by any man, except husband); tend to control their emotions and expressions of physical discomfort; do not address by first name until told to do so; modesty is important; father does not usually participate in birthing classes, labor, or delivery. **Remember that diversity exists within cultural groups and not to stereotype Ethnocentrism—belief that one's won ethnicity & culture are superior. Do NOT exhibit this. Collect data about unique characteristics of a clt's culture to provide culturally sensitive care: (58-60) Language & Communication style-eye contact, body space & distance, touch, emotional expression Hygiene practices Feelings about modesty—ask client whether the gender of her caregiver is of concern Special clothing or ornamentation Religion and religious practices (some muslin fathers whisper a prayer into neonates ear….p59) Rituals surrounding birth—inquire about practices while pregnant Family and gender roles Proper forms of greeting and showing respect Food habits and dietary restrictions (many Muslim and Jewish people do not eat pork) Methods for making decisions ATI-Women's health 8 Health beliefs and medical practices Ask about expectations regarding newborn care and care of pregnant women Mexicans- do not see eclipse—causes cleft palate Native Americans & Asians—preg. women should be active and walk Filipinos often believe any activity is dangerous Latinos may think that sexual activity during pregnancy keeps canal lubricated Vietnamese prohibit sexual intercourse during pregnancy harm to mom/fetus Culturally sensitive nursing interventions of the perinatal client and family include: Using a knowledgeable interpreter; Address the client as she prefers; Use culturally sensitive communication techniques (cultural comfort zone & appropriate eye contact); respect the client's food preferences; provide female caregiver if desired; respecting clt's decision regarding support person; honoring the clt's health beliefs and practices; apologize if traditions/beliefs are violated. Antepartum: Prenatla and Childbirth Education ATI 65-80 Prenatal education focus: self-care of discomforts of pregnancy, promoting safe outcome and positive feelings regarding the childbearing experience. The greatest period of danger to the developing fetus occurs between 17-56 days. Stress healthy behaviors; avoid: OTC meds, alcohol, tabacco, substance abuse. Nursing assessment in prenatal care includes: Reproductive & obstetrical history; medical history (include immune status); family history (genetic DOs), infections; current medications; substance abuse or alcohol use; psychosocial history (emotional response to pregnancy), hazardous environmental exposure, diet/exercise. Ascertain client's goals for birthing process. Prenatal educations topics based on clt's learning needs (current knowledge, previous preg/birth experience) 1st trimester: physical/psychosocial changes; common discomforts of pregnancy and relief measures; lifestye; complications and signs to report; choosing an obstetrician, fetal growth/devop; prenatyal exercise, expected lab testing 2nd trimester: plans to breast/bottle feed; common discomforts and relief measures; lifestyle; fetal mov't; complications, childbirth preparation 3rd trimester: birth plan; breathing/relaxation techniques; decisions about pain mgmt; S/S of labor; labor process; infant carte; postpartum care; fetal mov't counts 2-3 X/day (3 mov'ts/hr) Maternal adaptation to pregnancy: Emotional lability; ambivalence about pregnancy up to 3rd trimester Common discomforts of pregnancy --N/V—eat crackers/dry toast ½ to 1 hour before rising in AM; avoid empty stomach, spicy, greasy, or gas forming foods; drink fluids between meals --Breast tenderness—wear bra that provides adequate support --urinary frequency—during 1st and 3rd trimester; empty bladder frequently, limit fluid intake before bedtime, perform Kegel exercises --UTI's—common during preg RT renal changes and vaginal flora becoming more alkaline *Decreased risk: wipe from front to back, use soft, unscented TP, avoid bubble baths, use cotton underpants, avoid tight-fitting pants, drink 8+ glasses of water per day *Yogurt/acidophilus milk -- pH of urine and vaginal flora& cranberry juicepH of urine *Urinate before and after intercourse to flush bacteria from ureathra *Urinate as soon as the urge occurs—prevent retaining uringe *notify Dr. if urine is malodorous or contains blood or pus --Fatigue—during 1st and 3rd trimesters—engage in frequent rest periods --Heartburn—2nd and 3rd trimester—eat small frequent meals, stomach not to empty or full, sit up for 30 min after meals, ask Dr. prior to OTC antacids. --Constipations—2nd &3rd trimester—drink plenty of fluids, high fiber diet, exercise regularly --Hemorrhoids—2nd & 3rd trimester—warm sitz bath, witch hazel cool pads ATI-Women's health 9 --Backaches—2 & 3 —exercise regularly, do pelvic tilts, proper body mechanics, good posture, lie with legs slightly elevated. --SOB/dyspnea occurs in 60% of women RT 4cm rise of diaphragm—maintain good posture, sleep with extra pillows, do not overload stomach, contact Dr is symptoms worsen --Leg cramps—3rd trimester RT compression of nerves & BVs & imbalance in Ca/P ratio; If homan's sign is negative have client dorsiflex foot; stand with feet flat on the floor Message and apply heat over affected muscle while leg is extended; a foot massage while the leg is extended can help relieve cramping; Evaluate diet & Ca intake. Increase in milk will also increase P and will not help.

Majority of birth defects occur between 2-8wks. Prenatal care provides an opportunity for: Ensure adequate daily folic acid, update immunization, encourage smoking cessation, treat current infections, obtain genetic testing, provide counseling, ascertain maternal exposure to hazardous materials. Schedule: q monthly for 7 months; q 2 wks for 8th month; q weekly for 9th month ATI-Women's health 10 Prenatal visit assessments: Baseline weight, BP, fundal height (empty bladder first), leopolds maneuvers, pelvic exam (lst visit); costovertebralo angle tenderness (indicitive of renal infection); Homan's sign, urine test Routine Lab test during prenatal care: Blood type, Rh factor, antibody screen, CBC w/differential, Hgb, Hct, hemoglobin electrophoresis (identifiessicle cell /thalassemia), urinalysis (ID-DM, PIH, Renal disease, infection, occult hematuria), 1hr glucose tolerance at 24-28wks (>135 requires follow up); 3hr glucose (fasting overnight), venous blood sample checked at 1, 2, 3 hrs (2 elevated reading DM; PAP test; vaginal/cervical culture (STIs, GB strep at 35-37wks); rubella titer; PPD (tuberculosis); Hep B, Venereal Disease (syphilis screening mandated by law), HIV, TORCH (toxoplasmosis, other infections, rubella, cytomegalovirus, herpes virus) Ultrasound—20 min—early diagnosis of complications permitting earlier interventions External—noninvasive, painless, safe procedure Internal transvaginal—invasive procedure—more accurate evaluation; useful in obese clients, during 1st trimester, detect ectopic pregnancy, ID abnormalities, establish gestational age. During 3rd trimester used to evaluate preterm labor & accurate FHR patterns Doppler ultrasound blood flow analysis—measures speed of RBCs traveling through fetal/uterine vessels Useful in IUGR, identifying poor placental perfusion, adjunct in risk preg. RT HTN, DM, 2+fetuses Ultrasound indications for use: Pregnancy confirmation; gestational age; multifetal pregnancy; site of implantation; ectopic; fetal growth and developemtn, maternal structure assess; fetal viability or death confirmation; R/O or verify fetal abnormalities; vaginal beeding eval; amniotic fluid volume determination, fetal mov't observation (FHR, breathing, activity), placedntal grading, adjust for other procedures(amniocentesis, biophysical profile, PUB, etc.) Ultrasound nursing management: Drink 1-2 quarts of fluid prior to procedure Place clt in supine position with wedge under right hip (prevent supine hypotension) Nonstress test (NST)—eval of fetal well-being performed during 3rd trimester. Noninvasive procedure that measures response of FHR to fetal mov't. Doppler transducer used to monitor FHR, tocotransducer used to measure uterine contractions. Clt pushes button when she feels fetal mov't. Reassuring/reactive/normal if FHR accelerates 15 bpm for > 15 sec and occurs 2-3 X/20min (means placenta is adequately perfused and the fetus is well-oxygenated) Nonreassuring/nonreactive/abnormal if FHR does not accelerate adequately with fetal mov't or no fetal mov'ts occur. If nonreactive—further assessment with CST or BPP Disadvantesages: high # of false "nonreactive" RT fetal sleep cycles, smoking, meds, immaturity Indications for use of NST: All pregnancies in 3rd trimester, twice/week for clt's with DM or risk for fetal death NST nursing management Have client drink OJ or be given glucose to BG to stimulate fetal mov'ts; use semi-fowlers position; have clt push button when feels fetal mov't; if no fetal mov'ts vibroacoustic stimulation for 3 seconds to waken fetus. CST (contraction stress test)—stimulate contractions ( placental blood flow) and analyze FHR during contraction to determine how fetus will tolerate stress of labor.
