High Risk Pregnancy (1) Flashcards
what is an endocrine disorder involving inadequate insulin
diabetes mellitus
describe diabetes in early and late pregnancy?
- early = hormones stimulate insulin prod. and increase insulin response (low sugar)
- late = hyperglycemia and resistance to insulin, may have ketones in urine d/t fat metabolism (high sugar)
what is diabetes diagnosed through preganacy
gestational DM
will a gestational diabetic be diabetic for the rest of her life?
no
what is the normal reading of a 1hr gluc tolerance test?
135-140
what happens if a 1hr GTT exceeds 140?
3hr GTT is ordered
what are suspicious 3hr GTT results by hour?
- fasting= >95
- 1hr= >180
- 2hr= >155
- 3hr= >140
what is hyperglycemia from low insulin, inc. ketones in blood when fatty acids metabolize
ketoacidosis
what is when blood settles in the vasculature, associated w/ high blood sugar
vascular disease
what is neuropathy implication of pregnancy
settling sugar inc. blood sugar
what is when sugar settles in microvasculature of eyes
retinopathy
what is an increased amniotic fluis
hydramnios
what is dystocia
cephalic dysproportion (difficult labor)
what are some fetal implications of diabetes?
- inc. risk fetal death
- congenital abnormalities
- LGA/macrosomia
- intrauterine growth restriction!!! (IUGR)
- resp. distress syndrome
- hyperbilirubinemia
- hypocalcemia
if the baby is LGA and the mother has gestational diabetes, what can this mean for labor?
baby has low sugar! its not diabetic, lots of insulin
what are the insulin requirements in early and late pregnancy along with postpartum
- early= insulin need decreases
- late= insulin need greatly increases
- PP= insulin need decreases
who is at risk for gestational diabetes?
- women w/ hyperglycemia, glucosuria, obesity
- fam history
- prior LGA baby
- previous fetal demise
what diet should be encouraged with GDM?
ADA diet, low in carbs and calorie counting
what 3 things should be assessed in GDM/DM
- height/weight
- preg dates and fundascopic exam
- neuropathy and infection
what tests are used to assess the fetus of a diabetic mother?
- presence of fetal mvmt
- non stress test (NST)
- bio physical profile (BPP)
- ultrasound
what are the 2 types of anemia?
- insufficient hemoglobin production
- hemoglobin destruction
what are the types of insufficient hemoglobin production anemia and what is it r/t?
- iron deficient and folate deficient
- r/t nutritional deficiency
what is the main tyoe of hemoglobin desctruction anemia and what is it from
- sickle cell anemia
- r/t inherited disorders
what are possible complications from iron deficient anemia
-infection
-fatigue
-preeclampsia
tolerate blood loss poorly
what are possible fetal complications of iron deficient anemia
- low birth weight
- preterm delivery
- fetal demise
- neonatal death
prevention of iron deficienct anemia
- prenatal vitamins
- 60-120 mg iron/day
- iron rich diet
what are maternal complications of folate deficient (megaloblastic) anemia?
- n/v
- anorexia
prevention of folate deficient anemia
- 0.4 mg foalte/day
- 1 mg folate+iron supplement
what are possible fetal complications of folate deficient anemia
neural tube defects
who is at risk for sickle cell
autosomal recessive disorder
symptoms/complications of sickle cell
- abd/joint pain
- infection, CHF, renal failure
treatment of sickle cell anemia?
folic acid, prompt infection treatment, hospitalization during crisis
what are possible fetal complications of sickle cell
- fetal death
- prematurity
- IUGR
what is when abnormal hemoglobin is made and there is resulting excessive breakdown of blood cells. hepatosplenomegaly and bony formations may be present
thalassemia
who is at risk for thalassemia?
those from greece, italy, and china
what is treatment for thalassemia
folic acid, transfusion, chelation
what is the life expectancy of thalassemia without treatment
20-30 yr
describe mitral valve prolpase
mitral vlave leaflets prolapse into the left atrium
-regurgitation may result
-genrally asymptomatic
what is mitral valve prolapse treated with?
inderal
what is peripartum cardiomyopathy and when does it occur
- left ventricle dysfunction w/ no previous hx of herat diease
- occurs in second half of pregnancy
what are symptoms of peripartum cardiomyopathy
CP, dyspnea, orthopnea, weakness, edema
what is management of labor with heart disease
- no/slight limitation= may labor normal
- may limit pushing
- limit pain/anxiety (can inc. stress to heart)
what are the criteria for spontaneous abortion?
miscarriage prior to 20w
what kind of abortion is unexplained bleeding, cramping, cervix closed, possible abortion
threatened abortion
what kinf of abortion is where she is going to miscarry, inc. bleeding/cramping, cervix dialted, membrane rupture
imminent abortion
what kind of abortion is where parts of products are retained
incomplete abortion
what kind of abortion is where all products of cenception are expelled
complete abortion
what kind of abortion is where fetus dies in utero and is not expelled
missed abortion
