fish high in mercury, cold deli meats, raw meats and eggs, unpasteurized dairy products, liver, unwashed produce, alcohol, caffeine (no more than 200mg/day)
27
Drugs to avoid in pregnancy
NSAIDs, ACE inhibitors, ARBS, Retin A, sulfonamide an fluoroquinolone abx, codeine, warfarin, benzos, castor oil, mineral oil, bismuth subsalicylate, isotretinoin
28
prenatal / antepartum testing
blood type, Rh factor, STI testing, glucose test, UA, U/S, NST, GBS, kick counts
29
infant is put at risk for erythroblastosis fetalis when
mother is Rh negative and baby is Rh positive
30
Rhogam is given at ____ weeks and ____ weeks if mother is Rh ____
28 and 40 weeks; Rh negative
31
Rhogam
contains small amount of Rh proteins that stops blood from making Rh antibodies
32
Oral glucose tolerance test
done at 28 weeks, 50g glucose, BG checked 1 hr later, if greater than 140 (7.8mmol/L), the 3 hr glucose test is done
33
3 hr glucose tolerance test
done only if 1 hr is failed, fasting 8 hrs, 100g glucose drink, BG checked at 1hr, 2hr, 3hr; pass = no gestational diabetes, fail = + gestational diabetes
34
NST assesses
fetal well being and oxygenation of placenta, evaluates changes in fetal heart rate with movement
35
increase in fetal heart rate with movement (contraction) = _________ which is a _____ sign
acceleration = good sign
36
decrease in fetal heart rate with movement (contraction) = ________ which is a _____ sign
deceleration = bad sign
37
Reactive NST
at least two accelerations of 15bpm for 15 seconds in a 20 minute period
38
Non-reactive NST
not at least two acceleration of 15 bpm for 15 seconds in 20 min
39
fetal HR deceleration with movement is a sign that the fetus will not tolerate ______
labor
40
NST 3 N's
Nonstress test, non-reactive, not good!
41
Contraction Stress test
done when NST is non-reactive, always done in hospital as oxytocin is given to induce contractions, checks to see if baby will tolerate labor and shows signs of stress
42
Negative contraction stress test
Normal; baby did NOT have any decels in response to contractions
43
Positive contraction stress test
Bad; baby had decels with contractions indicating distress in response to movement
44
variability
fluctuation in fetal HR; absent, marked, or moderate
45
absent variability
very little to no fluctuation in FHR, bad sign
46
Marked variability
can be good or bad
47
moderate variability
ranges between 6 and 25 bpm; good sign
48
early decelerations
mirror the contraction; when contraction rises or falls decel also falls or rises as uterus compresses head/neck (stimulates vagus nerve causing HR to drop), not an issue as long as HR returns back to baseline when contraction ends
49
variable decelerations
do not match with contraction; decel is not dependent on contraction, likely cord compression or pressure on umbilical vein causing drop in HR, this is ALARMING! as fetal blood is suddenly being restricted, emergency C-section
50
Late decelerations
decels are late compared to contraction (decel begins after contraction began instead of at same time), indicates placental insufficiency, can be caused by epidural turned up to fast, sudden maternal hypotension, severe dehydration or anemia, can indicate sudden hemorrhage, emergency C-section
51
VEAL CHOP
Variable Deceleration -> Cord Compression Early Deceleration -> Head Compression Accelerations -> Okay! Late Deceleration -> Placental Insufficiency
52
Reassuring NST signs
baseline HR normal: 110-160 bpm moderate variability accelerations
53
Non reassuring NST signs
fetal tachycardia >160bpm fetal bradycardia <110bpm decrease variability variable decelerations late decelerations
54
Non-reassuring fetal HR nursing interventions
lay mother on left side increase IV fluids oxygen notify HCP discontinue pitocin
55
GTPAL
Gravidity - # of pregnancies including current, twins only count once (one pregnancy) Term - # of pregnancies to term, 37+ week gestation, twins only count once Preterm - # of preterm births, between 20 and 36+6 weeks gestation, twins only count once Abortions - # of pregnancies ending prior to 19+6 weeks, spontaneous or termination, twins count only once Living children - # of children currently alive, twins count twice
56
Hyperemesis Gravidarum
extreme morning sickness, intense n/v during pregnancy
57
Morning Sickness vs. Hyperemesis Gravidarum
nausea that may cause vomiting vs. nausea with excessive, persistent vomiting nausea subsides around 20 weeks vs. n/v does not subside vomiting does not cause dehydration vs. can cause dehydration, weight loss, electrolyte imbalances can keep some food down vs. cannot keep any food down
58
Hyperemesis Gravidarum management
sit up after meals, small portions, drink in between meals not with, nothing too spicy, hot, or cold (limit irritation), promethazine, IVF, TPN
59
Preeclampsia
htn occurring >20 weeks, BP >140/90 2 times, 4 hrs apart, protein in urine, can lead to eclampsia
60
preeclampsia S&S
increased BP sudden, big weight gain proteinuria facial puffiness pedal edema
61
preeclampsia management
delivery, prepare for preterm baby, magnesium sulfate (prevent maternal seizures), betamethasone (help develop baby's lungs), antihypertensives
62
antihypertensives that can be given during pregnancy and what can't
Yes: labetalol, nifedipine, hydralazine No: ACE Inhibitors, ARBs
63
HELLP Syndrome
hemolysis, elevated liver enzymes, low platelet count no known cause but preeclampsia or eclampsia have much higher risk needs very quick treatment and is life threatening
64
HELLP S&S
epigastric substernal pain (d/t liver enzymes being high), n/v and indigestion (d/t liver enzymes), severe headaches/blurry visions (due to high bp), severe swelling, SOB
65
HELLP syndrome management
corticosteroids, antihypertensives, administration of blood products/components, delivery
66
Gestational Diabetes
pancreas is unable to deal with increased insulin requirements of pregnancy
67
glucose tolerance test is done at ______ weeks
24-28 weeks
68
Gestational diabetes complications
macrosomia (large baby), preeclampsia, hypoglycemia in new born
69
cholestasis
maternal liver condition that typically occurs in later pregnancy causing bile acids to enter the bloodstream, as bile acids rise, fetal safety is significantly compromised. Bile acids in the bloodstream causes intense itching that is mostly on the soles of the feet and palms of the hands
70
cholestasis complications
mother: severe itching and scratching can lead to scarring, results in lower vitamin K-dependent factors, can impact the ability to clot baby: preterm birth, lung problems d/t aspiration of meconium, death
71
cholestasis tx
no known prevention focus is on recognition and intervention, give Ursodiol early in third semester (before 36 weeks) it helps to lower bile acids in the blood and can relieve some of the symptoms of itching, if before 36 weeks the fetus is closely monitored with NSTs at least twice weekly, if after 36/37 weeks plan to deliver no matter what
72
ectopic pregnancy
an egg is fertilized but implants outside the uterine cavity (fallopian tube, cervix, abdomen)
73
ectopic pregnancy symptoms
dizziness or fainting, n/v, abdominal or pelvic pain, loss of appetite, when rupturing/ruptured can quickly become hemodynamically unstable
74
ectopic pregnancy therapeutic management
prevent rupture (detect with U/S), methotrexate (stops embryo from being able to grow), Rh immune globulin (prevents erythroblastosis fetalis if mom is Rh negative)
