@ShopWithKey on Etsy OB Maternal Newborn ATI Exam Study Guide Video #1: Contraception & Infertility Diaphragms: client must be refitted for a diaphragm for the following conditions: 1. It’s been 2 years since she has been fitted 2. Gained more than 15 pounds (7kg) 3. Had a full-term pregnancy 4. Had a second term abortion o When you use a diaphragm, you need to use spermicide with every act of coitus (withdrawal of penis from vagina prior to ejaculation). Every time you withdrawal, instill more spermicide. o Diaphragm must stay inserted for 6hrs after act of coitus. Hormonal Contraceptives (Oral) o Side effects: Chest pain, SOB, Leg pain (from a possible clot), headache or eye problems (from a stroke or hypertension) o Contraindications: Women with a history of blood clots, stroke, cardiac problems, smoker, breast or estrogen related cancers (pill contains estrogen) Depo-Provera/Medroxyprogesterone o Injectable progestin o Can cause decreased bone mineral density or loss of calcium Nursing action: Ensure patient has adequate intake of calcium and vitamin D IUD o Increase risk for PID o Can cause uterine perforation or ectopic pregnancy (increases risk for ectopic pregnancy) o Look out for/Notify PCP: Change in string length IUD is moving and not in the right place Foul smelling vaginal discharge Pain with intercourse Fever/Chills (infection) Infertility is defined as an inability to conceive desire engaging in unprotected sexual intercourse for a prolonged period of time or at least 12 months. Common factors associated with infertility include: o Decreased sperm production (Sperm analysis) o Endometriosis o Ovulation disorders o Tubal occlusions If you test and use DYE (used in the fallopian tubes), make sure the woman is not allergic to iodine or shellfish/seafood Video #2: Signs of Pregnancy Presumptive: Can be defined by things/reasons other than pregnancy Amenorrhea Can be anorexic or exercising too much Fatigue Didn’t sleep well Nausea/Vomiting Sick Urinary Frequency UTI Quickening/Fluttering in stomach Gas 1 @ShopWithKey on Etsy Probable: Changes that make the examiner suspect a woman is pregnant (primarily related to physical changes of the uterus). Abdominal enlargement: Related to changes in uterine size, shape, and position Hegar’s Sign: Softening and compressibility of the lower uterus Chadwick’s Sign: Deepend violet bluish color of cervix and vaginal mucosa Goodell’s Sign: Softening of cervical tip Ballottement: Rebound of unengaged uterus Braxton Hicks Contractions: False contractions that are painless, irregular, and usually relieved by walking Positive Pregnancy Test: Woman’s hormonal level may not be normal Fetal Outline: Positive: Very distinct things. Fetal Heart Sounds Fetal Heartbeat can be heard Can see the baby with ultrasound Can feel movement in the uterus Naegele’s Rule: Last menstrual period minus (– ) 3 months + 7 days + 1-year ;Cathy’s Rule: + 9 months + 1 week Gravidity and Parity: Gravida: a woman who is pregnant Gravidity: number of pregnancies o Nulligravida: a woman who has never been pregnant o Primigravida: a woman who is pregnant for the first time o Multigravida: a woman in at least her second pregnancy. Parity: the number of births (not the number of fetuses [ex: twins]) carried pat 20 weeks gestation, whether or not the fetus was born alive. o Nullipara: a woman who has not had a birth at more than 20 weeks of gestation. o Primipara: a woman who has had one birth that occurred after 20 weeks of gestation. o Multipara: a woman who has had two or more pregnancies to the stage of fetal viability. Know how to find out GTPAL numbers: G= Gravidity (# of times a woman has been pregnant PLUS current pregnancy) T= Term Births (How many babies were delivered at term 38 WEEKS OR MORE) P= Preterm Births (Below 38 weeks) A= Abortion (spontaneous or not) or miscarriages L= Living children Fundal height: Measured to evaluate the gestational age of the fetus. During the second and third trimesters (weeks 18-30), the fundal height in centimeters approximately equals the fetus’s age in weeks, plus or minus 2 cm. At 16 weeks, the fundus can be found approximately halfway between the symphysis pubis and the umbilicus. 2 @ShopWithKey on Etsy At 20 to 22 weeks, the fundus is approximately at the location of the umbilicus. At 36 weeks, the fundus is at the xiphoid process. * When assessing fundal height, monitor the client closely for supine hypotension when place in the supine position. Measuring fundal height: 1. Place the client in a supine position 2. Place the end of the tape measure at the level of symphysis pubis 3. Stretch the tape to the tope of the uterine fundus 4. Note and record the measurement. Physiological Maternal Changes: Cardiovascular system: Circulating blood volume increases by approximately 40 – 50%; physiological anemia may occur as the plasma increase exceeds the increase in the production of red blood cells. Heart size is increased, and the heart is elevated upward and to the left because of displacement of the diaphragm as the uterus enlarges. There is an increase in the body’s demand for iron. Sodium and water retention may occur, which can lead to weight gain. Respiratory system: Oxygen consumption increases by approximately 15% to 20% Diaphragm is elevated as a result of the enlarged uterus Shortness of breath may be experienced. * During pregnancy, a woman’s pulse rate may increase about 10 to 15 beats/minute, the blood pressure slightly decreases in the second trimester, then increases in the third trimester but not above the pregnancy level; and the respiratory rate remains unchanged or slightly increases. Gastrointestinal System: Nausea and vomiting, which usually subsides by the 3rd month, may occur as a result of the secretion of human chorionic gonadotropin (hCG); hCG stabilizes or decreases around week 12 Poor appetite may occur because of decreased gastric motility. Alterations in taste and smell may occur. Constipation may occur because of an increase in progesterone production or pressure of the uterus, resulting in decreased GI motility. 3 @ShopWithKey on Etsy Flatulence and heartburn may occur because of decreased GI motility and slowed emptying of the stomach cause by an increase in progesterone production. Gum tissue may become swollen and easily bleed because of increasing levels of estrogen. Ptyalism (excessive secretion of saliva) may occur because of increasing levels of estrogen. Renal System: Frequency of urination increases in the 1st and 3rd trimesters because of increased bladder sensitivity and pressure of the enlarging uterus on the bladder, Decreased bladder tone may occur and is caused by an increase in progesterone and estrogen levels; bladder capacity increases in response to increasing levels of progesterone. The renal threshold fir glucose may be reduced. Reproductive system: 1. Uterus a) Uterus enlarges, increasing in mass from approximately 60 g to 1000 g as a result of hyperplasia (influence of estrogen) and hypertrophy. b) Size and number of blood vessels and lymphatics increase c) Irregular contractions occur, typically beginning after 16 weeks gestation. 2. Cervix a) Cervix becomes shorter, more elastic, and larger in diameter. b) Endocervical glands secrete a thick mucus plug, which is expelled from the canal when dilation begins. c) Increased vascularization and an increase in estrogen causes a softening and a violet discoloration (Chadwick’s sign), which occurs at about week 6. 3. Ovaries a) Secrete progesterone for first 6 to 7 weeks of pregnancy b) Block maturation of new follicles c) Cease ovum production. 4. Vagina a) Hypertrophy and thickening of the muscle occurs. b) Increase in vaginal secretions is experienced: secretions are usually, thick, white, and acidic. 5. Breasts a) Breast changes occur because of the increasing effects of estrogen and progesterone b) Breast size increases and breasts may be tender. c) Nipples become more pronounced and the areolae become darker. d) Superficial veins become prominent e) Montgomery’s follicles become hypertrophied f) Colostrum may leak from the breasts. Skin: Changes in skin occur because of increased levels of melanocyte-stimulating hormone, which increase secondary ot increases in estrogen and progesterone; these changes include the following: a) Increased pigmentation b) Dark streak down the midline of the abdomen may appear (linea nigra). 4 @ShopWithKey on Etsy c) Chloasma (mask of pregnancy), a blotchy, brownish hyperpigmentation, may occur over the forehead, checks, and nose. d) Reddish-purple stretch marks (striae) may occur over the abdomen, breasts, thighs, and upper arms Vascular spider nevi may occur on the neck, chest, face, arms, and legs. The rate of hair growth may increase. Musculoskeletal System: Changes in center of gravity begin in the second trimester and are caused by the hormones relaxin and progesterone The lumbosacral curve increases Aching, numbness, and weakness may result; walking becomes more difficult, and the woman develops a waddling gait and is at risk for falls. Relaxation and increased mobility of pelvic joints occurs, which permit enlargement of pelvic dimensions. Abdominal wall stretches with loss of tone throughout pregnancy, regained postpartum. Umbilicus flattens or protrudes. * During pregnancy, postural changes occur as the increased weight of the uterus causes a forward pull of the bony pelvis. It is important for the nurse to encourage the client to implement measures that maintain safety and correct posture to prevent a backache. Discomforts of pregnancy: Nausea and Vomiting. o Interventions: eating dry crackers before rising, avoiding brushing the teeth immediately after rising, eating small frequent low-fat meals during the day, drinking liquids between meals rather than at meals, avoiding fried and spicy foods, asking the primary health care provider about acupressure (some types may require a prescription), and asking if the PHCP about the use of herbal remedies. Syncope. o Interventions: sitting with the feet elevated and changing positions slowly because of the risk for falls. o The nurse needs to inform the pregnant client to avoid lying in the supine position, particularly in the second and third trimesters. The supine position places the woman at risk for supine hypotension, which occurs as a result of pressure of the uterus on the inferior vena cava. Urinary urgency and frequency. o Interventions: drinking no less than 2000 mL of fluid during the day, limiting fluid intake during the evening, voiding at regular intervals, sleeping on the side at night, wearing perineal pads if necessary, and performing Kegel exercises. Breast tenderness. o Interventions: encouraging wearing a supportive bra, avoiding the use of soap on the nipples and areolar area to prevent drying of skin. 5 @ShopWithKey on Etsy Increased vaginal discharge: o Interventions: Using proper cleansing and hygiene techniques, wearing COTTON underwear, avoiding douching, informing the client of the signs of infection and to consult the PHCP if an infection is suspected. Fatigue. o Interventions: arranging frequent rest periods throughout the day, using correct posture and body mechanics, obtaining regular exercise, performing muscle relaxation and strengthening exercises for the legs and hip joints, and avoiding eating and drinking foods that contain stimulants throughout the pregnancy. Heartburn. o Interventions: eating small frequent meals and avoid fatty and spicy foods, sitting upright for 30 minutes after a meal, drinking milk between meals, and consulting with the PHCP about the use of antacids. Ankle Edema: o Interventions: elevating the legs at least twice a day and when resting, sleeping in a side-lying position, wearing supportive stockings or supportive hose as prescribed, avoiding sitting or standing in one position for long periods. Varicose veins: o Interventions: wearing supportive stockings or support hose, elevating the feet when sitting, lying with the feet and hips elevated, avoiding long periods or standing or sitting, moving about while standing to improve circulation, avoiding leg crossing, avoiding constriction articles of clothing such as knee high stockings. Thrombophlebitis (is rare but can occur): o Interventions: teaching leg exercises and avoiding airline travel if possible. Headaches: o Interventions: changing positions slowly, applying a cool cloth to the forehead, eating a small snack, using acetaminophen only if prescribed by the PHCP Hemorrhoids: o Interventions: soaking in a warm sitz bath, sitting on a soft pillow, eating high fiber foods, and drinking sufficient fluids to avoid constipation, increasing exercise, such as walking, and applying ointments, suppositories, or compresses as prescribed by the PHCP. Constipation: o Interventions: eating high fiber foods such as whole grains, fruits, and vegetables, drinking no less than 2000 mL per day, exercising regularly, such as a daily 20 minute walk, and consulting with the PHCP about interventions such as the use of stool softeners, laxatives, or enemas. Backache: o Interventions: obtaining rest, using correct posture and body mechanics, wearing low- heeled, comfortable, and supportive shoes, performing pelvic tilt (rock) or tailor-sitting exercises and conscious relaxation exercises, sleeping on a firm mattress. Leg cramps: o Interventions: getting regular exercise, such as walking, dorsiflexing the foot of the affected leg, and increasing calcium intake. Shortness of breath: o Interventions: taking frequent rest periods and avoiding overexertion, sitting and sleeping with the head elevated or on the side, avoiding overexertion. 6 @ShopWithKey on Etsy Maternal Risk Factors Maternal age: women younger than 20 years and older than 35 years are at risk for advance perinatal outcomes. Adolescent pregnancy. o Major concerns related to adolescent pregnancy include poor nutritional status, emotional and behavioral difficulties, lack of support systems, increased risk of stillbirth, low-birth weight, fetal mortality, cephalopelvic disproportion, and increased risks of maternal complications such as hypertension, anemia, prolonged labor, and infections. o The role of the nurse is reducing the risks and consequences of adolescent pregnancy is twofold: first to encourage early and continued prenatal care, and second, to refer the adolescent, if necessary, for appropriate assistance, which can help to counter the effects of a negative socioeconomic environment. Nutrition: adequate nutrition is necessary for normal fetal growth and development. Nutrition needs are determined by the stage of the pregnancy and nutrition should support recommended weight gain during the various stages. * Women of childbearing age should take folic acid supplements to prevent neural tube defects and orofacial clefts in the fetus. Genetic considerations: genetic abnormalities such as defective genes or transmissible inherited disorders can result in congenital anomalies; the nurse should collect data about genetic risks. Health care: failure to seek and obtain prenatal care, including dental care, increases the risk of preterm birth and low birth weight. Abuse and violence: physical abuse and violence can increase the risk for abruptio placentae, preterm birth, and infections from unwanted and forced sex. Medical conditions: concurrent medical conditions, such as, but not limited to, diabetes mellitus, hypertensive disorder, or cardiac disease, increase the risk during pregnancy. German measles (rubella): maternal infection during the first 8 weeks of gestation carries the highest rate of fetal infection. Sexually Transmitted infections: Syphilis. o Organism may cross the placenta o Infection usually leads to spontaneous abortions and increases the incidence of mental sub normality and physical deformities. Condylomata acuminate (human papillomavirus) o Transmission may occur during vaginal birth. o Infection is associated with the development of epithelial tumors of the mucous membranes if the larynx in children. Gonorrhea. o Fetus is contaminated at the time of birth. o Maternal infection may result in postpartum infection of the neonate. o Risks to the neonate include ophthalmia neonatorum, pneumonia, and sepsis. 7 @ShopWithKey on Etsy Chlamydial infection. o Transmission may occur during vaginal birth and can result in neonatal conjunctivitis or pneumonitis. o Infection can cause premature rupture of the membranes, premature labor, and postpartum endometritis. Trichomoniasis. o Associated with premature rupture of the membranes and postpartum endometritis. Genital herpes simplex virus. o Characterized by painful lesions, fever, chills, malaise, and severe dysuria and may last 2 to 3 weeks. o Assessment includes questioning all women about signs/symptoms and inspecting the vulvar, perineal, and vaginal areas for vesicles or areas of ulceration or crusting; this is done during pregnancy and at the onset of labor. o Vaginal birth may be acceptable; cesarean birth is recommended if visible lesions are present. o Infants who are born through an infected vagina should be carefully observed, and samples should be taken for culture. Human immunodeficiency virus (HIV). o HIV is transmitted via blood, blood products, and other body fluids such as urine, semen, and vaginal secretions; the virus is also transmitted through exposure to infected secretions during birth and via breast milk. o Repeated exposure to the virus during pregnancy through unsafe sex practices and/or intravenous drug use can increase the risk of transmission to the fetus. o Perinatal administration of zidovudine may be recommended to decrease risk of transmission of HIV from mother to fetus. Substance abuse. o Substance abuse threatens normal fetal growth and the successful term completion of the pregnancy. o Substance abuse places the pregnancy at risk for fetal growth restriction, abruptio placentae, and fetal bradycardia. o Many substances cross the placenta and can be teratogenic; (drugs, tobacco, alcohol, medications, certain foods such as raw fish); no OTC medications should be taken unless prescribed. o Smoking (tobacco) can lead to low birth weight, a higher incidence of birth defects, and stillbirths. o Physical signs of drug abuse may include dilated or contracted pupils, fatigue, track (needle) marks, skin abscesses, inflamed nasal mucosa, and inappropriate behavior by the mother. o The consumption of alcohol during pregnancy may lead to fetal alcohol syndrome and can cause jitteriness, physical abnormalities, congenital anomalies and growth deficits. Video #3: Weight Gain & Nutrition During Pregnancy AND Diagnostic Tests During Pregnancy Weight Gain & Nutrition Normal weight gain = 25- 35 pounds Overweight person weight gain = 15- 25 pounds Underweight person weight gain = 28-40 pounds 8 @ShopWithKey on Etsy o The average expected weight gain during pregnancy is 25 to 35 pounds (11-16 kg) for women with a normal pre pregnancy weight, depending on PHCP preference. o An increase of about 300 calories per day is needed during pregnancy. o An increase of about 500 calories per day is needed during lactation. o A diet high in folic acid and folic acid supplements is necessary for all women of childbearing age to prevent neural tube defects and orofacial clefts in the fetus. o Encourage the consumption of at least 8 to 10 ( 8oz) glasses of fluid each day, of which 4 to 6 glasses should be water. o Sodium is not restricted unless specifically prescribed by the PHCP. During 1st trimester A woman should only gain 1-2 kg (2-4 pounds); A woman should not gain 1 pound per week. During 2nd trimester 1 pound per week is normal; increase caloric intake by 340 calories per day During 3rd trimester 1 pound per week is normal; increase caloric intake by 450 calories per day If you are breastfeeding after pregnancy You still need to eat an extra 300-400 calories per day Intake of FOLIC ACID Helps prevent Neural Tube Defects (NTD) Sources: dark green leafy veggies; orange juice Women should increase their fluid intake to 2-3L per day Women should limit their caffeine intake to 300 mg per day No amount of alcohol is okay Pica: is eating nonfood substances such as dirt, clay, starch, and freezer frost. The cause is unknown. Cultural values, such as beliefs regarding a materials effect on the mother or fetus, may make pica a common practice. Iron-deficiency anemia may occur as a result of pica Diagnostic Tests During Pregnancy Noninvasive = Full Bladder Invasive = Empty Bladder Ultrasound Bladder should be full to help sound waves resonate better Amniocentesis Bladder should be empty Biophysical Profile (BPP): Scored from 0-10 Score between 8-10 Healthy Baby. Tests Measures 5 things: o Reactive HR (0/2) o Breathing (0/2) o Body Movement (0/2) o Fetal Tone (0/2) o Amniotic Fluid Volume (0/2) Non-Stress Test (NST) Non-invasive Measures fetal well-being within the last trimester of pregnancy Measures response of FHR to Fetal Movement 9 @ShopWithKey on Etsy o Reactive: FHR accelerates during movement (normal; positive) o Nonreactive: No accelerations during movement (not normal; negative) If non-reactive, the DR will perform another test called: Contraction Stress Test (CST) or a BPP. Video #4: Diagnostic Tests Contraction Stress Test (CST) Induce contraction with administration of Pitocin/oxytocin or nipple stimulation During the contraction, monitor FHR for late decelerations Negative CST Response (no late decelerations, which is what you want) Positive CST (late decelerations happen, not a good thing) Risk o Can send woman into PTL Amniocentesis. Aspiration of amniotic fluid; best performed between 15 and 20 weeks of pregnancy because amniotic fluid volume is adequate and many viable fetal cells are present in the fluid by this time. Performed to determine genetic disorders, metabolic defects, and fetal lung maturity You want an empty bladder because you will poke into amniotic sac to test for genetic abnormalities (levels of AFP aka alphafeto-protein) o Interventions: if less than 20 weeks gestation, the woman should have a full bladder to support the uterus. If more than 20 weeks gestation, the woman should have an empty bladder to minimize the chance of puncture. Prepare the client for ultrasonography, which is performed to locate the placenta and avoid puncture of it. Obtain baseline vital signs and fetal heart rate. Monitor every 15 minutes. Position the client supine during the procedure and on the left side after the procedure. o High AFP = NTD o Low AFP = Chromosomal disorders such as down syndrome LS Ratio (Lecithin Sphingomyelin) tests for fetal lung maturity o Ratio of 2:1 = fetal lung maturity o Ratio of 2.5:1 or 3:1 = fetal lung maturity for client with DM Risks/Complications: o Amniotic Fluid Emboli (AFE) o Maternal Hemorrhaging o Infection o Premature rupture of the membranes o Rh isoimmunization o Miscarriage o Abruptio placentae Chorionic Villus Sampling (CVS) Alternative to Amniocentesis: Performed for the purpose of detecting genetic abnormalities; the PHCP aspirates a small ample of chorionic villus tissue at 10 to 13 weeks gestation. Can be done between 10-12 weeks Also tests for genetic abnormalities by testing the placenta instead of the amniotic fluid. Advantage Can be done earlier 10 @ShopWithKey on Etsy o Interventions: the client may need to drink water to fill the bladder before the procedure to aid in visualizing the uterus for catheter insertion; obtain baseline vital signs and fetal heart rate (monitor frequently after the procedure); Rh-negative women may be given Rh (D) immune globulin, because chorionic villus sampling increases the risk of Rh sensitization; make sure informed consent is signed. After chorionic villus sampling and amniocentesis, instruct the client that if chills, fever, bleeding, leakage of fluid at the needle insertion site, decreased fetal movement, uterine contractions, or cramping occurs she must notify the PHCP. Kick counts (fetal movement counting): The client is instructed to sit quietly or lie down on her side and count fetal kicks for a specific period of time. Instruct the client to notify the PHCP if there are fewer than 10 kicks in two consecutive 2-hour periods or as instructed by her PHCP. Fern Test: A microscopic slide test to determine the presence of amniotic fluid leakage. Using sterile technique, a specimen is obtained form the external os of the cervix and vaginal pool and examined on a slide under a microscope. A fern like pattern that results from the salts of the amniotic fluid indicates the presence of amniotic fluid. o Interventions: position the client in the dorsal lithotomy position; instruct the client to cough. This causes the fluid to leak from the uterus of the membranes are ruptured. Doppler blood flow analysis: Noninvasive (ultrasonography) method of studying blood flow in the fetus and placenta Percutaneous umbilical blood sampling: Performed if fetal blood sampling is necessary; involves insertion of needle directly into fetal umbilical vessel under ultrasound guidance. Fetal heart rate monitoring is necessary for 1 hour after procedure, and a follow-up ultrasound to check for bleeding or hematoma formation is done for 1 hour after the procedure. Alpha-fetoprotein (AFP) screening: Assess the quantity of fetal serum proteins; abnormal protein levels are associated with open neural tube and abdominal wall defects. Can screen for spina bifida and down syndrome; if abnormal, the test is repeated; a false-positive test result is common. o Interventions: the AFP level is determined by a maternal blood sample drawn between 16- and 18-weeks’ gestation. o If the level is abnormal and the gestation is less than 18 weeks, a second sample is drawn and screened. o An ultrasound is performed for elevated levels to rule out fetal abnormalities or multiple gestation. 11 @ShopWithKey on Etsy Biophysical profile: Noninvasive assessment of the fetus that includes fetal breathing movements, fetal movements, fetal tone, amniotic fluid index, and fetal heart rate patterns via a nonstress test. Normal fetal biophysical activities indicate that the central nervous system is functional, and the fetus is not hypoxemic. Nitrazine test: A Nitrazine test strip is used to detect the presence of amniotic fluid in vaginal secretions. Vaginal secretions have a pH of 4.5 to 5.5 and do not affect the color of the Nitrazine strip or swab. Amniotic fluid has a pH of 7.0 to 7.5 and turns the Nitrazine strip or swab blue in color. o Interventions: position the client in the dorsal lithotomy position, touch the test tape to the fluid, check the test tape for a blue0green, blue-gray, or deep-blue color, which indicates that the membranes are probably ruptured, causing leakage or amniotic fluid. Fibronectin Tests: Sampling of cervical and vaginal secretions for fetal fibronectin is done (a protein present in fetal tissues normally found in cervical and vaginal secretions until 16-20 weeks gestation and again at or near term). Positive results indicate the onset of labor in 1 to 3 weeks; negative test results are more predictive that preterm labor will not begin. Test is used if the client is at risk for preterm labor, before 37 weeks gestation. o Interventions: client is placed in lithotomy position for a sterile speculum examination, cervical secretions are obtained with a cotton swab, and laboratory tests are done for the presence of fibronectin. Nonstress test: Performed to assess placental function and oxygenation; determines fetal well-being; and evaluates fetal heart rate (FHR) in response to fetal movement. o Interventions: an external ultrasound transducer and tocodynamometer are applied to the mother, and a tracing of at least 20 minutes duration is obtained so that the FHR and the uterine activity van be observed. o Obtain a baseline blood pressure reading and monitor frequently. o Position the mother in left lateral position to avoid vena cava compression. o The mother may be asked to press a button every time she feels fetal movement. The monitor recorded a mark at each point of fetal movement, and this is used as a reference point to assess FHR response. Contraction Stress Test: Assesses placental oxygenation and function; determines fetal ability to tolerate labor and determine fetal well-being. Fetus is exposed to the stress of contraction to assess the adequacy of placental perfusion under simulated labor conditions. Performed if the nonstress test is abnormal. o Interventions: the external fetal monitor is applied to the mother, and a 20 to 30-minute baseline strip is recorded. o The uterus is stimulated to contract, either by the administration of a dilute doe of oxytocin or by having the mother use nipple stimulation, until three palpable 12 @ShopWithKey on Etsy contractions with a duration of 40 seconds or more during a 10 minute period have been achieved. o Frequent maternal blood pressure readings are obtained and the mother is monitored closely while increasing doses of oxytocin are given. Video #5 Bleeding and Complications During Pregnancy Ectopic Pregnancy Ovum is planted outside of the uterus, often in the fallopian tube. Need to know the symptom of unilateral stabbing pain in the lower abdominal quadrant o If it burst the fallopian tube, it can be life threatening to the mom Gestational Trophoblastic Disease (GTD) the proliferation and degeneration of trophoblastic billi in the placenta that becomes swollen, fluid-filled, and takes on the appearance of grape-like clusters or prune juice. Placenta Previa Placenta previa occurs when the placenta abnormally implants in the lower segment of the uterus near or over the cervical os instead of attaching to the fundus. PAINLESS BRIGHT RED VAGINAL BLLEDING during the 2nd or 3rd trimester o Very dangerous May hemorrhage and may need to give blood o Complete or Total: Cervix is completely covered by placental attachment o Incomplete or Partial: Partially covered by the placental attachment o Marginal or low-lying Abruptio Placenta: the premature separation of the placenta from the uterus, which can be a partial or complete detachment. o Sudden onset of intense localized uterine pain with dark, red, vaginal bleeding. o Clinical Findings: Hypovolemic shock Yeast Infections are quite common for pregnant woman o Signs/Symptoms: Cottage cheese discharge Vulvar redness White patches on vaginal wall Incompetent Cervix: Recurrent premature dilation of the dilation of the cervix or cervical insufficiency (basically the cervix cannot stay closed and will lead to a spontaneous abortion if not taken care of). If woman has incompetent cervix, she will get a cerclage to help keep cervix closed and from dilating and is removed at 37 weeks of gestation or when spontaneous labor occurs. Hyperemesis Gravidarum Nausea and vomiting that goes past 12 weeks. End up having weight loss & electrolyte imbalances & dehydration. o Nursing Interventions: IV Fluids, administration of B6, antiemetic medication (Reglan or Zofran). Video #6: Medical Conditions Iron Deficiency Anemia Provider will prescribe FE supplements Take FE Supplement that is rich in Vitamin C (i.e orange juice) Gestational Diabetes (GDM) If a patient has GDM during pregnancy, it increases her risk of developing DM after her pregnancy 13 @ShopWithKey on Etsy Poses risk to the fetus. Provider may want to do BPP or NST to monitor for complications Most oral anti-diabetic meds are contraindicated for pregnancy so woman will have to use insulin to monitor sugar levels When to test: 24 – 28 weeks of gestation o Start with 1-hour glucose tolerance test No fasting required Give patient 50g of oral glucose, then 1 hour later, test glucose levels Positive screen of 130-140mg/dl or greater indicates need for additional testing (3 Hr OGTT) o 3 Hr OGTT Requires fasting Avoid caffeine and smoking Will take fasting glucose level, then will be given 100g of glucose and will test glucose at 1hr, 2hrs, and 3hrs Gestational Hypertension (GHTN) Caused by vasospasm contributing to poor tissue perfusion Spectrum of GHTN o GHTN after 20th week of pregnancy, if a woman has a BP over 140/90 recorded at least twice, 4-6 hrs apart within a one-week period of time, the patient is POSITIVE for GHTN. There is NO PROTEIN in urine. o Mild Preeclampsia GHTN (BP 140/90) Proteinuria (Level 1+) Edema may not be present ATM o Severe Preeclampsia BP >/=160/100 + Proteinuria (Level 3+) Creatinine levels will begin to rise and will be >1.2 May experience headache/blurred vision/hyperreflexia/peripheral edema/Epigastric pain o Eclampsia Severe Preeclampsia + Seizures o HELLP Hemolysis: resulting in anemia and jaundice Elevated Liver Enzymes: ALT & AST Levels will be high Manifestations: Epigastric pain, nausea, vomiting Low Platelets: Platelet count < 100k Manifestations: o Thrombocytopenia o Abnormal bleeding and clotting time o Bleeding gums o Petechiae o Possibly disseminated intravascular coagulopathy Medications: Antihypertensives o Methyldopa o Nifedipine 14 @ShopWithKey on Etsy o Hydralazine o Labetalol o ** AVOID ACE inhibitors and ARBS Anticonvulsants o Magnesium sulfate: Monitor patient for magnesium toxicity! Signs & Symptoms No reflexes, reduces DTR, low urine output, RR low, LOC low, dysrhythmias Antidote: Calcium Gluconate Video #7: Early Onset of Labor PTL Contractions or cervical changes that happen between 20-37 weeks. After 37 weeks, it will be considered Full Term Labor May do a vaginal swab to check the fetal fibronectin to see if she is in PTL o May administer Nifedipine (Calcium Channel Blocker) Will relax muscles by suppressing contractions by blocking calcium being transported to smooth muscles o May administer Magnesium (check for toxicity) relax smooth muscles of uterus o May administer Indomethacin NSAID which inhibits prostaglandins inhibits prostaglandins suppresses UCs o May administer betamethasone Steroid Help promote fetal lung maturity PROM Major cause of infection (especially if more than 24 hours goes by from when the membrane ruptured and the time the baby is born) o If membrane ruptures DR will order a Nitrazine paper test Paper turns blue (pH 6.5- 7.5) o Positive ferning test can also indicate rupture of membrane o If membrane does rupture, patient will be put on an antibiotic, betamethasone (develop baby’s lungs) Physiological Changes Preceding Labor: Backache Weight Loss Lightening (Fetal head drops into the true pelvis) Contractions (True, not Braxton hicks) Bloody show Energy burst right before labor GI Changes (nausea, vomiting, indigestion) Rupture of membranes (check with Nitrazine paper) Tests Done: Group B Strep Urinalysis (Protein, infection) 15 @ShopWithKey on Etsy 4 Stages of labor: 1st Onset of labor until complete dilation of cervix (10 cm) o Has 3 phases Latent 0-3 cm dilation o Mother is talkative & eager Active >3-7cm o Mother is restless, anxious, and may feel helpless Transition >7cm-10cm o Mother is experiencing a lot of pain, has urge to push and may feel like she is having a bowel movement (increased rectal pressure) 2nd Full dilation of cervix to birth of the baby 3rd Birth of baby to delivery of placenta 4th Delivery of placenta until mothers’ vitals are stable Video #8 Pain Management & FHR Monitoring Non-pharmacological methods Aromatherapy Imagery Music Effleurage: light, gentle circular stroking of the client’s abdomen with the fingertips in rhythm with breathing during contractions Sacral Counter-pressure: Consistent pressure is applied by the support person using the heel of the hand or fist against the client’s sacral area to counteract pain in the lower back Pharmacological Methods (Sedative & Opioid analgesics) Sedative puts baby at risk for respiratory depression Opioid Analgesic puts mom at risk for sedation, hypotension, and increased variability in FHR Epidural Analgesia Provides lack of sensation at level of the umbilicus to the thighs. Needs to be dilated at least 4cm or above Side effects include: maternal hypotension and fetal bradycardia. Nursing Interventions Give IV Bolus to counteract hypotension; want to avoid supine hypotension syndrome (avoid this by placing patient on her side and not on her back). Spinal Block: provides lack of sensation from the nipples to the feet. Given for C-Sections.
