time frames of “prolong latent phase” When should you artificially rupture membranes?

nullip >20 hours multip >14 hours tx: rest or augmentation do no rupture in latent phase because increased risk of infection

if fetal heart tones are baseline 150 with a category 1 tracing do you need to do a contraction stress test for preterm labor?

NO, category I means they are contracting with variability and accels

contraindications for: -terbutaline -mag sulfate -indomethacin

-terbutaline in diabetics, or over 48 hours -mag sulfate in myastehnia gravis (resp depression) -indo after 33 weeks for closure of ductus

late term preg associations?

macrosomia oligohydramnios meconium aspiration ureteroplacental insufficiency

fetal dysmaturity

seen over 43 weeks withered, meconium stained, long fingernails, small placenta

antibiotics for mastitis

dicloxacillin, cephalexin

why would you think candida mastitis?

nipple pain out of proportion to physical exam burning, shotting pain

things to think about with uterus small for gestational age

oligo IUGR IUFD

pharm for hyperemesis gravidarum? vs pharm for NVP?

zofran (odansetron) reglan (metoclopramide) pyridoxine (B6) and doxylamine

maternal risk factors assoc with ASSYMETRIC IUGR? When in pregnancy does this occur?

think of DISEASE states: dm,htn,sle,cvd smoking/cocaine this tends to occur LATER in pregnancy 80% of IUGR is ASSYM.

twins from 4-8 day splits? 13?

Mo, Di 4x2=8 13= unlucky= conjoined

what murmur on PE are you concerned about, what are you not?

systolic is not concerning diastolic (think mitral stenosis) can be sign of heart failure

most common defects seen in women with diabetes before pregnancy?

problems with organogenesis --\> mostly cardiac or NTD

how do you manage a patient who fails GTTs?

diet and exercise.

do you see IUGR with gestational diabetes?

no, generally pre-existing

potential lab finding indicative of contractions due to dehydration?

ketones in the urine

therapuetic range of mag? resp depression range?

4-7mEq/L 11-14

definition of hydrops

fluid accumulation in two or more body cavities -ascites -pleural effu -pericardial effu -scalp edema

what should you look for on exam of high AFP before jumping to NTD?

high fundal height --\> think twins!

what should you look for on exam of high AFP before jumping to NTD?

high fundal height --\> think twins!

most proven way to prevent preterm birth in twin gestation?

good weightgain early, 20-24 weeks. This will help to grow the placentas

whats a b-lynch suture?

technique for ligating uterine vessels surgically in PPH when pharm has failed

nerves at risk from low transverse incision? decribe their course

ilioinguinal, iliohypogastric --\> both exit T12/L1, through psoas, laterally through transversus abd, courses on anterior abd wall to ASIS, then medially between internal/external oblique. Becomes CUTANEOUS 1cm sup to inguinal ring hypogastric does sensation of groin/skin overlying pubis inguinal does sensation of symphysis, groin, labium, UPPER THIGH

pain with adduction indicative of what nerves? inability to adduct indicative of what nerve?

iliohypogastric, ilioinguinal obturator

if OCPs are not adequately controlling hirsituism, what can youadd?

spirinolactone

physiology of increased free T in PCOS?

inc LH--\>inc androgen production --\> dec sex hormone binding globulin --\> increase free T

how do combo OCPs help with dysmen?

progestin causes endometrial atrophy --\> endometrium produces prostaglandins which causecramping

how can BSO after menopause "recreate" menopausal symptoms?

ovaries continue to produce androgens which get peripherally converted to estrogen

how long to wait to attempt pregnancy after mole?

6 months AFTER last negative bhCG

how does HPV/pap screening workfor women ages 30-65?

HPV testing every FIVE years, but acceptable to do pap alone every three years

CT or US for evaluting female pelvic anatomy?

US!!

salpingectomy vs salpingostomy. Which one needs bhCG f/u?

salpinectomy removes entire chunk of tube with pregnancy and does not require f/u salpingostomy just remove pregnancy via hole intueb and DOES REQ F/U
