Final Test Flashcards
Nagele’s Rule
minus 3 months from LMP and add 7 days
Prenatal assessment at each office visit
urine dip, weight, BP, listen for fetal heart tones after 12 weeks, measure uterus(#cm=#weeks after 20 weeks) &at end of pregnancy check fetal position and cervix for dialation and effacement
What are presumptive(possible) signs of pregnancy?
(subjective)
-amenorrhea
-fatigue
-urinary frequency
-breast changes
-uterine enlargement
-quickening (movement)
What are probable signs of pregnancy?
(objective)
- positive urine pregnancy test
-hegors sign (softening of lower uterus)
-chadwicks sign ( bluish color of cervix)
-goodells sign (softening of cervix)
-ballottement (rebound of unengaged fetus)
-braxton hick contractions
-abdominal enlargement
what are the positive signs of preganancy?
diagnostic:
audible fetal heart tones via doppler, ultrasound @ 4-6 weeks and feeling baby move by examiner(20 weeks)
what is placenta previa?
when the placenta implants in the lower segment of the uterus near or over the cervical os;
abnormal implantation results in bleeding in the 3rd trimester as cervix begins to dilate and efface
what is important to remember with previa?
NO cervical exams
risk factors for placenta previa?
previous placenta previa, uterine scarring from surgery or infection, advanced maternal age, multifetal gestation, closely spaced pregnancies, smoking
manifestations of placenta previa?
painless, bright red bleeding in 2nd and 3rd trimester; uterus is soft and nontender; FH noted; make sure H and H stable; rhogam if needed; US to diagnose
what is an ectopic pregnancy?
abnormal implantation of the ovum outside of the uterus (typically in the fallopian tube)
betamethosone use
it can help speed up lung development in preterm babies. Betamethasone causes the release of surfactant, a substance that lubricates the lungs so that they do not stick together when the infant breathes.
What is placental abruption?
premature separation of the placenta from the uterus which can be partial or complete detachment;
significant maternal and fetal morbidity and mortality; leading cause of maternal death
risk factors for placental abruption?
maternal HTN, blunt force trauma, cocaine use, smoking, folate deficiency, premature rupture of membranes, multifetal gestation
what is terbutaline?
beta-adrenergic agonist used as a tocolytic to relax smooth muscle and inhibit uterine activity; administer SQ, monitor for CNS stimulation (tachycardia, tremors, nervousness, etc)
What is magnesium sulfate?
tocolytic that is a CNS depressant and relaxes smooth muscles, thus inhibiting uterine activity by suppressing contractions; administered IV; need to monitor mother closely
HELLP syndrome stands for
hypertension in pregnancy as well as Hemolysis, Elevated Liver enzymes, Low Platelet
antidote for magnesium sulfate?
calcium gluconate or calcium chloride
what do you monitor for with magnesium sulfate?
magnesium toxicity and discontinue for loss of deep tendon reflexes, urine output less than 30ml/hr, resp rate less than 12, pulmonary edema, severe hypotension, or chest pain
what is gestational hypertension
BP is 140/90 in normotensive woman after 20 weeks gestation on two occasions and without proteinuria
when does bp return to normal after gestational hypertension
12 weeks postpartum
when is the glucose tolerance test done
24-28 weeks gestation
risk factors for gestational hypertension
-age younger than 19 or over 40
-1st pregnancy
-extreme obesity
-family hx of GH
-multifetal pregnancy
-chronic hypertension
-chronic renal disease
-family hx of preeclampsia
-DM
-rheumatoid arthristis
-systemic lupus erythematosus
Difference between pre-eclampsia and eclampsia
eclampsia has siezures
what manifestations are seen with preeclampsia
-Gestational hypertension with the addition of proteinuria of greater than or equal to 1+.
-report of transient headaches may occur along with episodes of irritability
edema can be present
