Midterm Pt 1 Flashcards
Quickening/Lightening primigravidas
First perception of fetal movement 18-20 weeks
Quickening/Lightening multigravidas
First perception of fetal movement 14-16 weeks
Cholasma/Melisma/Mask of Pregnancy
Hormonal reaction causing darkening of skin like freckles; occurs around 16 weeks gestation
Linea Nigra
Dark line from umbilicus to pubis; due to splitting of rectus abdominus
Piscacek’s sign
Asymmetrical enlargement of uterus
Chadwick’s
Blueish or purplish discolouration of vagina and cervix
Braxton Hicks contractions
Usually occur around 28 weeks
Artificial ptocin
Induces side to side contractions
Morning sickness
Occurs in 50% of pregnancies between 5-18 weeks
Hyperemesis gravidum
Loses 5% of body weight, dehydration, ketosis, electrolyte abnormalities
Rh Incompatibility
Rh- mother, Rh+ baby: mother creates antibodies against baby
Rh Incompatibility complications
Heart failure
Kernicterus: bilirubin encephalopathy
Hydrops fetalis: gross edema of whole body
Fundal Height
Measured every week after 20 weeks; equal to weeks of gestation +/- 2cm.
Abnormal fundal height
Too small; growth issue of baby, amniotic fluid loss
Too large; twins, big baby, weight gain of mom
Effacement (labour term)
Shortening and thinning of cervix
Engagement (labour term)
Fetal head passes into the pelvic cavity
Bloody show (labour term)
Mucous plug releases from cervix
Lochia
Vaginal discharge 1-2 weeks after birth
Progression of lochia
1st rubra: blood tinged mucous
2nd yellow: mucous and blood
3rd white/alba: just mucous
Fetal station
Measurement as fetus descends into birth canal
Fetal station measurements
Ischial spine at 0; higher is negative 1-5; lower is positive 1-5. Birth begins around zero
Pre-eclampsia
aka toxemia of pregnancy
aka pregnancy induced hypertension (PIH)
Usually begins around 24th week (in 5-10% of pregnancies). Uterine hypertonia and hyperirritability are a high risk for premature contractions
3 Cardinal signs of pre-eclampsia
Rise in BP (along with headache)
Edema
Protinuria
Amniotic Fluid Disorders 1
Oligohydraminios: too little amniotic fluid. Early on causes club foot deformities and pressure on cord. Late also causes intrauterine growth retardation, fetal distress. Usually tough labour or C-section needed
Amniotic Fluid Disorders 2
Polyhydraminos: too much fluid (2000mL)
C-section is needed. Occurs in 1% of cases Can indicate maternal diabetes or congenital malformation.
Gestational Diabetes
Fasting blood sugar > 130 mg/dL
Infant of Diabetic Mother (IDM)
Usually 2x the size of a normal kid with enlarged heart and liver.
Iron deficiency anemia
Do not take pills
Ectopic pregnancy
Embryo implants outside endometrium; always fatal to embryo, often fatal to mom
Ectopic pregnancy presentation
Px will have stomach cramping and possible bleeding from birth canal; beginning shortly after 1st missed period
Ectopic pregnancy risk factors
Tubal disease, exposure to DES or induced abortion
Miscarriage
Usually before 20th week of pregnancy (usually 5-6 weeks)
Miscarriage etiology
Severe physical shock, uterine abnormalities, acute infections, endocrine abnormalities
Signs of miscarriage
Cramping, pain, vaginal bleeding, diffuse low back pain
Group B Strep
Present in 10-35% of healthy women; puts baby at higher risk of pneumonia or meningitis; mom needs antibiotics
Sequela of group B strep
Baby difficulty with temperature regulation, grunting sounds, fever, seizures, breathing problems, failure to thrive
3rd trimester bleeding
Sudden painful vaginal bleeding, medical emergency
Placenta previa
Placenta is slipping off the uterine wall so there is limited blood supply
