antipardum exam Flashcards
(225 cards)
adaptations of pregnancy - cardio - arteries and blood volume (not thicken)
Main uterine artery doubles in size
Increased blood volume by 40-50%
adaptations of pregnancy - skeletal
Shifting center of gravity
Increase lordosis
Loosening of the ligaments of the pubic symphysis and sacroiliac joints
Muscles of abd stretch and lose tone. Can lead to diastasis recti abdominis
adaptations of pregnancy - integumentary (melatropin in niagra)
Decreases in melanotropin- increase in areas of pigmentation (areolas and nipples)
Chloasma (melasma)
Striae gravidarum- stretch marks
Linea nigra (dark line down abdomen)
adaptations of pregnancy - GI (just relaxed)
Relaxed GI leads to constipation
Bleeding gums due to increase in vascularity
adaptations of pregnancy - GU - renal pelvis (hyper renal is relaxed)
Renal pelvis and ureters dilate: smooth muscle walls of the ureters undergo hyperplasia and hypertrophy (enlargement) and muscle tone relaxes.
adaptations of pregnancy - respiratory - increase or decrease?
Major change in shape to make room for growing uterus and fetus inside
Increased O2 consumption
Increased RR
adaptations of pregnancy - reproductive
Amenorrhea
Endometrium grows to support the embryo and fetus.
Increase in elastic properties
adaptations of pregnancy - reproductive - vagina (mucosa vault)
Vagina: increased mucosa, loosening of connective tissue, lengthening of the vaginal vault, increased vascularity,
What is GBS and when is screening done? (Diabetic in your 30s)
Group B Strep, a gram + organism that colonizes in the female genital tract and rectum; present in 10-30% of all healthy women, asymptomatic but can cause GBS disease of the newborn
Screening btw 36 - 38 weeks
Nonstress test (NST) (don’t stress the heart) - at what age is it recommended, and for who? (don’t stress 28 days later)
Nonstress test (NST) (lasts 20 minutes) is the most common method of prenatal testing used. Provides an indirect measurement of uteroplacental function. Recommended twice weekly, after 28 weeks gestation (3rd trimester), for clients with diabetes and other high-risk conditions. It measures the heart rate of the unborn baby (fetus) in response to its movements. In most cases, the heart rate of a healthy baby increases when the baby moves.
Nonstress test (NST) - results (stressed in 15 and 15)
Reactive = 2 accelerations in 20 minutes; accelerations are FHR equal or greater than 15 BPM over baseline lasting 15 seconds or more, occurs twice during NST (called acceleration)
Non-reactive = abnormal, does not meet criteria; indicates the need for more testing
What are good sources of iron?
Raisins! Red meat, chicken, fish, green leafy vegetable, soy products, nuts and dried fruit, dried beans, eggs, fortified grains
What are good sources of calcium?
Dairy products (milk, cheese, and yogurt), cereals; broccoli, spinach, and kale; salmon
What foods should the woman NOT eat while pregnant?
Artificial sweeteners: risk for higher newborn weight and childhood obesity
Mercury in fish: dangerous in high amounts; contribute to pregnancy complications and developmental problems in the infant
Listeriosis - raw dairy, fruit, fish
GDM/DM in pregnancy (Gestational diabetes mellitus) - fetus
macrosomia (large fetus) resulting from hyperinsulinemia stimulated by fetal hyperglycemia
Hypoglycemia
Childhood obesity
Hyperbilirubinemia
birth trauma due to shoulder dystocia (mechanical problems during delivery)
Congenital anomaly due to hyperglycemia in the 1st trimester (cardiac problems, neural tube defects, skeletal deformities, and genitourinary problems)
Premature birth secondary to polyhydramnios (too much amniotic fluid) and an aging placenta; places the fetus in jeopardy
Fetal asphyxia secondary to fetal hyperglycemia and hyperinsulinemia
Intrauterine growth restrictions secondary to maternal vascular impairment and decreased placental perfusion, which restricts growth
Perinatal death due to poor placental perfusion and hypoxia
Respiratory distress syndrome resulting from poor surfactant production
Polycythemia (a blood disorder) due to excessive RBC production in response to hypoxia
GDM/DM in pregnancy (Gestational diabetes mellitus) - maternal (the 2 big ones) (think of your pt)
preeclampsia and cesarean birth; greater risk of developing cardiovascular disease
Gestational hypertension of unknown etiology
Ketoacidosis due to uncontrolled hyperglycemia
Preterm labor secondary to premature membrane rupture
stillbirth in pregnancies
Hydramnios
Hypoglycemia as glucose is diverted to the fetus (in 1st trimester)
UTIs resulting from excess glucose in the urine
Chronic monilial vaginitis due to glucosuria (promotes yeast growth)
Difficult labor
tetarogens
Teratogens are substances that may produce physical or functional defects in the human embryo or fetus after a pregnant woman has been exposed. Can cause physical deformities, problems in the behavior or emotional development of the child, and decreased IQ. susceptibility depends on the timing of the exposure and the developmental state of the embryo or fetus
alcohol
Alcohol: spontaneous abortion, inadequate weight gain, IUGR (intrauterine growth restriction), FASD (fetal alcohol syndrome)
opiates (pre-opiates)
maternal and fetal withdrawal, placental abruption, preterm labor, premature rupture of membranes, perinatal asphyxia, newborn sepsis and death, malnutrition and intellectual impairment
meth
risk of preterm birth, low birth weight, placental abruption, fetal growth restrictions, and congenital abnormalities
cigarettes
nicotine causes vasoconstriction, and can transfer across the placenta reducing blood flow to the fetus and contributing to fetal hypoxia. Increases risk for spontaneous abortion, tubal ectopic pregnancy, preterm labor and birth, fetal growth restriction, stillbirth, premature rupture of membranes, low fetal iron stores, maternal hypertension, SIDS, cardiac arrhythmias, placenta previa, and placental abruption. Perinatal death rate is higher in infants of smokers. Increased risk of cleft lip and palate, clubfoot, asthma, middle ear infections, reduced head circumference, altered brain stem development, and cerebral palsy. Risk factor for low birth weight, cognitive deficits especially in language, reading, and vocabulary; poorer performances on tests of reasoning and memory; behavioral problems such as increased activity, ADHD, impulsivity, opposition and aggression
Toxoplasmosi
caused by a parasite; cats primary host; spread by contaminated soil, raw meats, and unwashed fruits and veg. Fetus is high risk for preterm labor and stillbirth; low birth weight, enlarged liver and spleen, visual problems, cerebral palsy, hearing loss, seizures, chorioretinitis, jaundice, IUGR, hydrocephalus, microcephaly, neurologic damage and anemia
STIs - effects on baby
depends on the type but effects include: eye infections, pneumonia; low birth weight, stilllbirth, preterm birth; intrauterine growth restrictions; intellectual disabilities, blindness, seizures, premature birth, death; skin ulcers, weakness or hoarse cry, deafness, swollen liver and spleen, amnesia, various deformations; HIV positive status; warts in throat; premature rupture of membranes
Rh factor incompatibility - where is it found? (R loves R)
Rh factor is a protein found on the surface of RBCs
