University of North Carolina Wilmington School of Nursing NSG 330 MaternalInfant Nursing Exam 1 Study Guide Spring 2016 (Modules 2 & 3) Module 2: Conception and Fetal Development, Chapter 12. Module 3: Anatomy & Physiology of Pregnancy (Antepartum); Nursing Care of the Family During Pregnancy; Maternal & Fetal Nutrition; Assessment of High Risk Pregnancy Chapters 13, 14, 15, 26, 19 (p. 431 only). PowerPoints: Conception & Fetal Development Anatomy & Physiology of Pregnancy Nursing Care of the Family During Pregnancy Maternal & Fetal Nutrition Word Document: Assessing Fetal Wellbeing Content: Explain products of conception, such as umbilical cord, amniotic fluid, and placenta. Umbilical Cord Two arteries: from embryo to placenta One vein: carries oxygenated blood with nutrients from placenta to fetus 30 to 90cm long, 2 cm diameter Wharton’s Jelly surrounds the cord vessels Nuchal cord: when the cord is wrapped around the fetus’ neck Amniotic Fluid protects fetus from trauma protects fetal movements regulates temperature excretion repository fetus swallows it and also urinates into it protects from membranes to facilitate growth slightly yellow to clear with no odor fluid flows in and out of fetal lungs increases weekly, and fluctuates during pregnancy replaced every 2 hours 1 800 to 1200 ml at term oligohydraminos: less than 300 ml possible renal abnormalities hydraminos: more than 2 liters GI and other malformations contains albumin, urea, uric acid, creatinine, lecithin, sphingomyelin, bilirubin, fat, fructose, inorganic salts, epithelial cells, some leukocytes, enzymes and lanugo hairs Placenta fxns as lungs, GI tract, and kidneys structure complete in 12 week grows until the 20 week transplants living tissue within the same species without usual immune response placental barrier is semipermeable Cotyledons: 1520 subdivisions 2 main protein hormones Human Chorionic Gonadotropin (hCG) trophoblast, then chorionic villi of placenta pregnancy test beginning 710 days after fertilization preserves fxn of corpus luteum to produce progesterone and estrogen for pregnancy miscarriage occurs if corpus luteum stops before placenta produces enough hormones maximum level 5070 days after gestation, sharply decreases, before leveling off at 80 days remains stable until 30 weeks, then gradually increases until term higher levels indicate multiple pregnancies, down syndrome, or abnormal pregnancy lower levels indicate ectopic pregnancy, or impending miscarriage Human Chorionic Sommatotropin (hCS) formerly known as Human Placental Lactogen (hPL) similar to growth hormone stimulates maternal metabolism to supply the fetus needed nutrients increases resistance to insulin facilitates glucose transport across placental membrane stimulate breast development to prepare for lactation Identify developmental landmarks during the embryonic and fetal periods, i.e. organ development (Mainly use Powerpoint). 4 Weeks 0.4 to 0.5 cm; 0.4g heart developing and beginning to beat double chambers visible aortic arch & major veins completed other systems rudimentary 8 Weeks 2.5 to 3cm; 2g body fairly wellformed 2 cerebral cortex and GI system developing 1 indication of bone ossification heart plan final sex organs distinguishable 12 Weeks 6 to 9cm; 19g bile secreted nails and vocal chords appearing some bones welloutlined blood forming in marrow kidney able to secrete urine brain roughly complete early taste buds lungs have definite shape sex recognizable 16 Weeks 11.5 to 13.5 cm; 100g head still dominant face looking human meconium in bowel most bones ossified heart muscle well developed elastic fibers in lungs cerebral lobes defined testes positioned for descent 20 Weeks 16 to 18.5cm; 300g venix caseosa (cheeselike white coating on babies when they are born) and lanugo (fine hairs) appearing 24 Weeks 23 cm; 600g ability to hear Know general effects of teratogens on pregnancy and timeframe for greatest risk. the general effects of teratogens produce LBW babies, malformations, organ systems, and main external features. The timeframe of the greatest risk if from day 15 to 8 weeks (1 trimester). Interpret BMI, total weight gain, and weight gain patterns during pregnancy. Know normal BMI. 3 Underweight: <18.5 2535 lbs Normal: 18.5 to 24.9 2840 lbs Overweight: 25 to 29.9 1525 lbs Obese: >30 Multiple pregnancy 3545 lbs Underweight: 0.5 kg/wk in 2 and 3 trimesters nd rd Normal: 0.4 kg/wk in 2 and 3 trimesters Overweight: 0.3 kg/wk in 2 and 3 trimesters weight gain should take place throughout pregnancy poor early pregnancy: SGA (small for gestational age) poor late pregnancy: preterm even if weight gain is adequate, these issues can arise both PATTERN and AMOUNT are important Determine gravidity and parity using the GTPAL system. G: number of total pregnancies T: number of pregnancies ending after 37 weeks P: number of pregnancies ending after 20 weeks but before 37 weeks A: number of pregnancies ending before 20 weeks L: number of children that are living Ex) Madison is experiencing her fourth pregnancy. Her first pregnancy ended in a spontanous abortion at 12 weeks, the second pregnancy resulted in the live birth of twin boys at 32 weeks gestation, and the third resulted in the live birth of a daughter at 39 weeks. G: 4 T: 1 P: 1 A: 1 L: 3 Calculate EDB using Naegele’s rule. Nagele’s Rule take the first day of LNMP, subtract 3 months, add 7 days. Add one year (if necessary) Ex) LNMP: June 13, 2012 subtract 3 months: March add 7 days: 20 add one year EDB (Estimated Date of Birth): March 20, 2013 Explain progression of normal fundal height during pregnancy. rises to umbilicus at 2224 weeks and xyphoid process at 36 weeks, dropping at 40 4 Explain recommended vitamins, minerals, and other major components of diet during pregnancy. Folic acid to prevent neural tube defects 0.6mg or 600mcg per day (increase about 50%) leafy green vegetables, organ meats, grains folate is found naturally, folic acid is fortifying IRON (30 mg daily) and FOLIC ACID (50% more) are the highest needs Iron helps prevent anemia, and folic acid helps prevent neural tube defects physiologic anemia is normal during the pregnancy d/t increased RBCs minerals, electrolytes, and vitamins protein 3 servings daily, 4 servings if teenager meat, eggs, milk, peanut butter NO high protein supplements caffeine decrease because it causes vasoconstriction of blood vessels can cause Intrauterine Growth Restriction (IUGR) and spontaneous abortion nd rd add 300 kcal/day for the 2 and 3 trimesters First trimester: little change Second: some change Third: significant change Recognize foods that would provide essential nutrients during pregnancy. water, milk, dairy, fish, dark leafy greens, liver, meats, fruits, vegetables, nuts, whole grains Describe nutritional discomforts during pregnancy (such as nausea & vomiting, heartburn, pica), possible complications, and suggested remedies. Nausea and Vomiting dry and starchy foods not a lot of fluid frequent small meals (q 23 hrs) do not skip meals move slowly decrease fried, fatty and spicy foods breathe fresh air cool and low aroma foods do not brush teeth right after eating because of gagging salty and tart foods help with nausea herbal teas antiemetics 5 vitamin B6 Ginger Hyperemesis Gravidarum prolonged, severe N/V can cause dehydration, ketonuria, electrolyte imbalances, and weight loss the cause is unknown happens to 1 in 200300 women higher chance if the baby is female if it is prolonged, it can cause IUGR or preterm birth irritability, tearfulness, mood changes hospitalization monitor I&Os IV replacement hyperemesis diet clear liquids, dry toast to crackers (dry to soft) vitamin B6, Unicom, Phenergan, Reglan Constipation increase fiber increase fluids regular moderate exercise Pyrosis/Heartburn small frequent means fluids BETWEEN meals ONLY avoid spicy foods no tight clothing do not lie down after eating Pica eating things that have no nutritional value Ex) Ice, clay, dirt, laundry starch most common in African American women, women in rural areas, and those with family hx interferes with absorption of nutrients lowers hemoglobin levels Corn starch is more popular in blacks Tierra, a soil used for pottery, is common in Mexican Americans Food Cravings ice cream pickles pizza could possibly be nutrients missing in diet 6 Explain typical physical and psychological changes during pregnancy Cardiovascular Heart enlarges slightly (hypertrophy) due to:* Increased blood volume (40-50%) nd Cardiac output (30-50% by end of 2 trimester) Red blood cell volume increases by 18-30% (approximately 450 ml) Increased vascularity nd Plasma increases especially 2 trimester Apical pulse shifted up and laterally about 1 cm Pulse increased 10-15 bpm (14-20 weeks)* Cardiac rhythm may be disturbed Systolic BP stays the same or may decrease slightly* Diastolic BP decreases, then becomes more normal near term* Heart palpitations may occur Supine hypotension*- prevent by putting a pillow for elevation of the lower back Physiologic anemia is normal due to increase in plasma exceeding number of RBCs Hemoglobin < 11 is not normal * White blood cell count increases* Due to the high flow and increased resistance (normal CV changes), it is similar to sepsis Left ventricular hypertrophy Musculoskeletal Diastasis recti abdominis: the separating of the abdominal muscles (rectus abdominis) o Relaxin causes this Shift in center of gravity so their muscles have to adjust** Increase in weight and postural changes (center of gravity changes goes forward) o Increased lumbosacral curve ** Uterus is pushed back over the pelvis Pelvis tilts forwards. – uterine ant flexion** Decreased abdominal muscle tone Duck waddling gait*** Realignment of spinal curvatures Decreased tone of smooth muscle b/c of progesterone increases*** o Progesterone also loosens the ligaments in the pubic symphysis and sacroiliac joints The ligaments and muscles in middle and lower spines are severely stressed 7 Gastrointestinal Gums tend to bleed easily and become spongy and hyperemic (pregnancy gingivitis) Appetite increases and fluctuates** Increased progesterone causes constipation and acid reflux** Indigestion and heartburn can develop as early as the 1 trimester (pyrosis) Hiatal hernias can be caused by the enlarging uterus Dec tone and motility of smooth muscles Constipation Morning sickness Iron is absorbed more readily* Gallbladder is often distended because of decreased muscle tone= dec emptying of GB May develop gallstones Pica: cravings for nonedible foods Hypersalivation (ptyalism)* Three P’s (pica, ptyalism, pyrosis) Renal/ urinary Renal plasma flows increases (peaks at end of 1 trimester) = more efficient kidneys in early pregnancy Frequency= increase bladder pressure Increased pH bc of inc glucose= Increased risk for UTI’s** Slower urine flow rate Dec bladder tone Decrease BUN, creatinine, uric acid Respiratory Increased size of thoracic cage* Diaphragm displaced by up to 4 cm.* State of compensatory respiratory alkalosis** Gradual increase in oxygen consumption,** Oxygen requirement increases in response to increased BMR** & need to add to tissue matter in uterus and breast Elevated levels of estrogen cause ligaments of the ribcage to relax, permitting increased chest expansion Chest breathing replaces abdominal breathing, becomes less possible for the diaphragm to descend with inspiration Thoracic breathing is accomplished primarily by diaphragm than by the costal muscles Upper Resp Tract becomes more vascular** in response to elevated estrogen As capillaries become engorged, can cause edema and hyperemia develop in the nose, pharynx, larynx trachea and bronchi and causes nasal stuffiness*** can also cause tympanic membranes gestation tubes to swell and leading to impaired hearing and ear aches The respiratory center has a lower threshold for CO2 due to estrogen and progesterone 8 Can cause Epistaxis Neuro decreased attention, concentration, and memory during and shortly after pregnancy decline in memory that could not be attributed to other physical changes of pregnancy (like depression) sleep problems compression of pelvic nerves sensory changes in legs * dorsallumbar lordosis can cause pain * edema can result in carpal tunnel syndrome during last trimester acroesthesia = numbness and tingling in limbs (even causes pain)** tension headaches** common with anxiety lightheadedness**, faintness, and syncope common in early pregnancy Endocrine thyroid increases in size and activity and can be palpated * increase in basal metabolic rate* increased parathyroid activity pituitary enlarges in 9 month and produces FSH, LH, thyrotropin, adrenotropin and prolactin* increased maternal blood glucose increased insulin needs bc there is a decrease ability for cells to take up insulin placenta produces HCGHPL Skin Warm temperature Acne Hyperpigmentation* (melasma or chloasma “Mask of pregnancy”; darkened plotches/ spots usually around face Linea nigra* Palmar erythema* Stretch marks/ striae gravidum* (during pregnancy= pink/purple stripes; postpartum= usually permanent and silvery stripes) Hair and nails grow rapidly After delivery hair loss occurs until 612 months postpartum Increased sweating/perspiration Hirsutism* excessive hairiness (usually unwanted malepattern hair growth on a woman's face, chest, and back) Epulis* any tumor like enlargement (i.e. lump) situated on the gingival or alveolar mucosa (word literally means “on the gingiva”) Breast 9 Tenderness due to elevated estrogen and progesterone Nipples and areola darken Montgomery’s Tubercles Hypertrophy of sebaceous glands that go away after prego Progressive Breast Enlargement Striae Gravidarum Heaviness, tingling, fullness Colostrum* Starts dav around third month Could express at 16 weeks as thin watery secretions Nutritious for baby for 45 days Vagina strongly influenced by estrogen hypertrophy hyperplasia of lining Operculum: mucous plug Leukorrhea: whitish vaginal discharge that fills the vaginal area near the cervix and acts as a barrier Ph of vaginal secretions more acidic due to increased lactic acid= prone to vaginal infections especially yeast Increased vaginal and pelvic vascularity and sensitivity may lead to increased sexual interest and arousal Uterus Enlarges:** high levels of estrogen & progesterone in 1st trimester, then mechanical pressure of growing fetus Changes Shape: Pear shape to globular to ovoid 2 ounces (60 grams) to 2 pounds (1000 grams) Changes Position: Rises to umbilicus at 2224 weeks & typhoid at term inc weight inc fibrous tissue braxton

changes 10 -1 trimester: nervous, emotional, anxious -2 : introverted, fetal attachment -3 : overprotective, finishing plans, role change, grief over lost roles Differentiate presumptive, probable, and positive signs of pregnancy. presumptive (subjective) probable (objective) positive (due to the the fetus) Differentiate typical changes in maternal VS and lab values (hemoglobin, hematocrit, platelets, white blood cells) and urine protein during pregnancy. Heart rate: increases 1015 bpm BP: remains at prepregnancy level in first trimester, slight decrease in 2nd trimester, return to prepregnancy level in 3rd trimester position of pt can affect BP Blood Volume: increases 4050% Respiratory rate: unchanged or slightly increased Decreased hmt/hgb Increase volume Increase WBC Decrease platelets HcG is the biochemical marker for pregnancy and detected with urine samples. ** know rules about pregnancy tests. Also monitor for proteins and glucose in urine Recognize appropriate anticipatory guidance for care during pregnancy, managing common discomforts (Table 142 on pages 324325).

Increased risk of complications because they’re still developing body Goal to reduce LBW infants- really prone to having Lbw Increased risk of obesity later in life Improve nutritional knowledge Promote access to prenatal care Decrease barriers to change in adolescent population Determine immunizations that are safe or unsafe during pregnancy. Safe immunizations Rubella Tetnas diptheria rabies hepatitis B recombinant flu vaccine because it’s not a virus UNSAFE immunizations any live virus immunization MMR (measles, mumps, rubella) (if titer is negative, give immunization 6 weeks after delivery) Describe assessments and screenings typically performed on first prenatal visit and those performed during ongoing routine prenatal visits. Prenatal Care Visits Initial visit when the woman suspects she is pregnant, usually after missed period 13 usually the longest visit Subsequent visits first visit within the first trimester (12 weeks) every month between the 16 and 28 weekh every 2 weeks between the 19 through 35 weekth th every week from 36 week until birth if problems arise, she goes more often Assessment on the initial visit chief concern first day of LNMP (last normal menstrual period) cramping, spotting, bleeding? hx of menstrual periods date of conception and EDD (Estimated Delivery Date) contraceptive hx feelings about the pregnancy any discomfort since LNMP gynecologic hx family profile current and past medical history medical history of both mother and father religious and/or cultural perspectives prenatal care modesty and clothing view of healthcare prescriptions and proscriptions response to emotions physical activity and rest eating habits occupational history and personal habits be aware of teratogens and riskiness the 1 trimester is the most harmful to the baby personal information physical exam lab tests UA: protein and glucose Blood: typing, Rh factor, CBC, H&H injections: Hep B, Rubella titer, Varicella titer, toxoplasmosis, syphilis (RPR and VDRL), gonorrhea and chlamydia culture, TB, renal fxn (BUN), sickle cell, cystic fibrosis, HIV, assessment of the well being of the baby Standard prenatal lab tests: when performed and purpose (Chapter 14, p. 312 Table 141). H&H, WBC, differential: detects anemia and infection 14 Hemoglobin electrophoresis: Identifies women with hemoglobinopathies (sickle cell, etc) Blood type, Rh, irregular antibody: identifies women who are risk for developing erythoblastosis fetalis or hyperbilirubinemia Rubella titer: determines immunity to rubella PPD: chest film after 20 weeks in women with positive skin test. Urinalysis: identifies women with glycosuria, renal disease, hypertensive disease of pregnancy, infection, occult hematuria, hCG for confirmation of pregnancy Urine culture: identifies women with asymptomatic bacteriuria Renal fxn tests: evaluates level of possible renal compromise in women with hx of DM, HTN, or renal disease Pap test: screens for cervical intraepithelial neoplasia; also HPV Cervical cultures for Gonorrhea and Chlamydia: screens for asymptomatic infection at 1 visit Vaginal/anal culture: GBS test done at 3537 weeks for infection RLR, VDRL, or FTAABS: identifies women with untreated syphilis HIV antibody, hep B, toxoplasmosis: screens for the specific infections 1 hour glucose tolerance: gestational diabetes, done at initial visit for women with risk factors, done at 2448 weeks whose initial screen was negative and others not tested 3 hour glucose tolerance: gestational diabetes, women with elevated 1hour test, must have 2 elevated test for diagnosis Cardiac evaluation, ECG, chest xray and echocardiogram: evaluates cardiac functioning in women with a Hx of HTN or cardiac disease Interpret patient antepartum assessments and prioritize patients with risk factors. First Trimester/ initial assessment all the history (slide 1012 of nursing care ppt) including physical exam/ vaginal exam estimation of birth date Nagele’s rule look for different signs prego test (ELISA is most popular) detect HcG in urine and detected 714 days after conception palpate ab and fetus ( leopold maneuvers/ ballottement) Hegar’s sign (inc softening an vascularity of lower uterus at 612 weeks) Goodell’s sign (inc softening of cervical tip at 5 weeks) Chadwick’s sign (inc vascularity leading to purplebluish color about 68 weeks) past pregnancy history (GTPAL) gravidity, term births (>37), preterm (up to 37), abortions/miscarriages, living children Fetal assessment Gestational age Chromosome testing (11 to 14 weeks) if indicated Health status Ultrasound (56 weeks) 15 : confirm pregnancy, verify location of the pregnancy, detect multiple gestation, confirm fetal viability, determine gestational age, determine the position of the uterus and cervix, guide the needle insertion for CVS. UA always done every visit to look at proteins and glucose lab tests: Hemoglobin; hematocrit; WBC; differential Blood type; Rh; irregular antibody Rubella titer PPD tuberculin test Urinalysis; urine culture Renal function tests Pap test Cervical cultures and vaginal smears for gonorrhea, chlamydia, and cytologic studies RPR, VDRL (for syphilis) FTAABS HIV antibody strongly recommended Hepatitis B if not received proof must get Anti body/ antigen Toxoplasmosis (parasite test) Second trimester Fundal height FHR Lab testing (urine for sugar/albumin) MSAFP* (16-18 weeks) Blood screening test determine -If higher= more than one baby or May determine neural tube defect If lower= down syndrome O’Sullivan 1-hour glucose screening (24-28 weeks)- non fasting test If not at minimum range- give a 3 hr glucose test Multiple-Marker or Triple Screen ** (16-18 weeks): MSAFP, hCG, unconjugated estriol; placental hormone (inhibin A) Everyone woman should get the triple screen], but mainly recommended in women with birth defects in family, 35 and older, has diabetes and uses insulin, uses harmful meds, viral infection during pregnancy, and exposed to high levels of radiation Quad Screen (15-20 weeks) 16 Third trimester/ ongoing prenatal care Measure fetal growth Determine fetal activity and well-being Assess effect of pregnancy processon mother’s health and well-being: adaptation; risk factors; culture; stressors Assess strengths and resources Provide for educational needs Fetal well being (look at document and ATI book) Biophysical Profile (BPP)- real time ultra sound Non stress test (NST)- monitors response of FHR to fetal movement. rd Done during 3 tri Contraction stress test (CST) (nipple or oxytocin stimulated)- assesses FHR to contractions -done over 10 min period with 40 to 60 seconds each - negative results= no late decelerations Amniocentesis- aspiration of amniotic fluid done usually at 14 weeks -used for Alpha-fetoprotein (if high = neural tube defect; if low= down syndrome) -used for fetal lung tests (lecithin/sphinogomyelin (L/S) = 2:1; indicates lung maturity; also phosphatidylglycerol should be present) Percutaneous Umbilical blood sampling (PUBS) -for high risk pregs -fetal blood sampling that looks at CBC, blood gases, karyotyping, Rh antibodies Chronic Villus Sampling (CVS) -for high risk pregs -assessment of developing placenta during the 10-12 weeks of gestation; alternate for amniocentesis -it’s an earlier Dx for abnormalities GBS (35-37 weeks)- Group Beta strep 17 Can pass to baby during delivery Can give baby bacterial respiratory infection Leading cause of neonatal sepsis and death 20-30% positive; in African American Adequate nutrition Kegal exercises Regular dental care **Periodontal disease= preterm birth; lbw babies; inc risk for pre- eclampsia No live virus immunizations Tetnas; diphtheria, rabies, hep B (recombinant), flu vaccine shot bc it is not virus = CAN GIVE MMR, chicken pox= DON’T GIVE Management of common discomforts (examples on slides 45-47) Assess birth plan and setting Danger signs of pregnancy Visual disturbances or severe headaches Facial edema or swelling of fingers Fever; nausea and vomiting Change in fetal activity patterns Vaginal bleeding or fluid Abdominal or epigastric pain Uterine contractions, pressure, cramping Explain danger signs that should be reported by pregnant woman to health care provider (Chapter 14, p. 314). 18 First Trimester severe vomiting chills, fever burning on urination diarrhea abdominal cramping, vaginal bleeding Second and Third Trimesters persistent, severe vomiting sudden discharge of fluid from vagina before 37 weeks vaginal bleeding, severe abdominal pain chills, fever, burning on urination, diarrhea severe backache or flank pain change in fetal movements uterine contraction; pressure; cramping before 37 weeks visual disturbances: blurring, double vision or spots swelling of face or fingers and over sacrum headaches: severe, frequent or continuous muscular irritability or convulsions epigastric or abdominal pain glycosuria, positive glucose tolerance test reaction Describe the educational needs of the woman throughout each trimester of pregnancy. The overall goal for education: To assist individuals and family members to make informed, safe, wise decisions about pregnancy, birth, and early parenthood, comprehend longlasting potential that childbirth experiences can have in the lives of women, and convey the impact of early parenting experiences on the development of children and family. SLIDES 53-65 First trimester -if you suspect you’re prego, stop harmful behaviors ( teratogens can harm when you don’t know you’re prego) - consult medications taken with doctor -educate this is the most vulnerable trimester for the fetal development -edu on nutrient requirements (IRON= 30 mg/ daily; FOLIC ACID= 50% or more) -edu the importance of weight gain based on BMI Second trimester -explain what each screening is for -tell about different prenatal providers (physicians, nurse- mid wife, doula) Third trimester 19 -educate about support system - educate about different birth settings -Early methods of childbirth education Grantly Dick-Read: Helps you relax and breathing techniques during labor Lamaze: relax by muscle isolation Bradley: Partner coach; emphasized partner’s presence during preg. And relaxing environment -give info about birthing center options - edu on pain management, childbirth prep, relaxation techniques, imagery - Childbirth education teaches tuning in to the body’s inner wisdom and strategies that enhance coping during labor and birth - encourage to attend a pregnancy support class - teach about breastfeeding if they are wanting to Know how a home pregnancy test is conducted to achieve more accurate results. Home pregnancy tests are based on hCG especially the Beta portion. It can be detected in urine 78 days after implantation. These have high accuracy because it measures the exact amount of hCG in the blood and can detect even small amounts. hCG levels greater than 25 IU/L are diagnostic for pregnancy. A common error is doing the test too early and receiving a false negative. Describe nursing care to prevent supine hypotension in a pregnant woman. Encourage pt to engage in maternal positioning on the leftlateral side, semi fowler’s position, or if supine, with a wedge placed under one hip to alleviate the pressure to the vena cava. Describe test, when usually performed, its purpose, interpretation of results, and nursing care for ultrasound (abdominal and transvaginal) (chapter 26, pp. 635639) and MSAFP (pp. 64546). Ultrasonagraphy (Abdominal) more useful after the 1 trimester woman should have a full bladder Ultrasonography (Vaginal) used in the 1 trimester to detect ectopic pregnancies, monitor the developing embryo, help identify abnormalities, and establish gestational age. useful in obese women optimal to view the pelvic structures Indications for use 20 provides earlier diagnoses thereby decreasing severity and morbidity nurses counsel and educate women about the procedure First Trimester number, size and locations of gestational sacs presence or absence of fetal cardiac and body movements presence or absence of uterine abnormalities (bicornuate uterus or fibroids) adnexal masses (ovarian cysts or ectopic pregnancy) pregnancy dating Second and Third Trimester fetal viability number position gestational age growth pattern anomalies amniotic fluid volume uterine fibroids or anomalies adnexal masses cervical length MSAFP (Maternal Serum AlphaFetoprotein) screening tool for NTD (neural tube defects) 8085% of all open NTDs and open abdominal wall defects can be detected early can be performed any time between 15 and 20 weeks of gestation AFP is found in the fetal GI tract and liver Explain major components and rationale of teaching an adolescent who is pregnant. Increased risk of complications because they’re still developing body Goal to reduce LBW infants- really prone to having Lbw Increased risk of obesity later in life Improve nutritional knowledge Promote access to prenatal care Decrease barriers to change in adolescent population Describe signs/symptoms that determine when the pregnant woman should go to the hospital to be evaluated for onset of true labor (p. 431 upper right of page, Teaching for Self Management: How to Distinguish True Labor From False Labor.) True Labor: Contractions occur regularly, becoming stronger, lasting longer, and occurring closer together 21 become more intense with walking are usually felt in the lower back, radiating to the lower portion of the abdomen continue despite use of comfort measures Cervix (by vaginal exam) shows progressive change (softening, effacement, and dilation signaled by the appearance of bloody show) moves to an increasingly anterior position Fetus presenting part usually becomes engaged in the pelvis, which results in increased ease of breathing; at the same time, the presenting part presses downward and compresses the bladder, resulting in urinary frequency False Labor Contractions occur irregularly or become regular only temporarily often stop with walking or position change can be felt in the back or the abdomen above the umbilicus can often be stopped through the use of comfort measures Cervix (by vaginal exam) may be soft but with not significant change in effacement or dilation or evidence of bloody show is often in a posterior position Fetus presenting part is usually not engaged in pelvis Differentiate roles of a midwife, obstetrician and doula. Obstetrician: the physician , sees low risk and high risk pregnancy women, pharmacologic and medical management of problems as well as use of technologic procedures Nurse Midwives cannot do Csections and can only work with noncomplicated births, nurses’ training then midwifery program Directentry midwife: do not have nurses’ training Doula: a person who is like a coach 22
