ATI Maternal Newborn Flashcards

Question

respiratory changes during pregnancy

Answer 1

oxygen needs increase, lung capacity decreases, RR increases

Answer 2

becomes softer, blue purple color

Answer 3

larger breast

Answer 4

chloasma - brown patches on the face linea nigra - a line that runs from the navel to the pubic bone striae gravidarum- stretch marks

Answer 5

maternal hypotension due to weight of the uterus on the vena cava

Answer 6

Teach the patient to lay on the left side in semi fowlers position or place wedge under one hip when supine

Answer 7

The indirect Coombs test determines if the mother is Rh negative or Rh positive for Rh negative patients repeated 24-28 weeks administer RhoGAM at 28 weeks

Answer 8

vaginal, anal culture was taken at 35-37 weeks

Answer 9

taken at 24-28 weeks no fasting required result should be less than 140 mg/dl

Answer 10

if the first test was over 140 fasting is required

Answer 11

taken at 15-22 weeks to screen for down syndrome (low) and for neural tube defects (high)

Answer 12

total weight gain should be 25-35 lbs for total pregnancy 1st trimester - 2.2. lbs - 4.4 lbs 2nd and 3rd 1 lb per week overweight - 15 - 25 lbs underweight - 28-40 lbs

Answer 13

no additional calories during 1st semester 340 extra cals during 2nd trimester 462 extra cals during 3rd trimester breastfeeding 450-500 extra caks

Answer 14

Genetic disease that causes the amino acid phenylalanine to build up in the body, posing a risk of birth defects in the fetus

Answer 15

adhere to PKU diet 3 months prior to pregnancy and through pregnancy monitor blood levels during pregnancy

Answer 16

avoid foods high in protein meat fish poultry nuts eggs dairy

Answer 17

Drink 1 quart of water prior to the procedure, better reflects sound waves

Answer 18

uses real-time ultrasound technology to assess fetal well being score from 8-10 is normal lowe than 8 can mean asphyxia

Answer 19

reactive FHR - +2 non-reactive - 0 fetal breathing movement - 1 or more eps for 30+ secs = +2 gross body movements - 3 or more body/limb extensions with the return to flexion +2, 3 or less = 0 fetal tone - 1 or more episodes of extension with a return to flexion +2 amniotic fluid volume - 1 pocket greater than 2 cm in 2 perpendicular planes +2, less = 0

Answer 20

a noninvasive test that measures FHR response to fetal movement performed during the 3rd trimester. acoustic vibration device may be used to awaken a sleeping fetus. mom pushes button when she feels fetal movement

Answer 21

decreased fetal movement, diabetes, gestational HTN, post maturity

Answer 22

Reactive - NORMAL FHR has a normal rate, moderate variability, and accelerates more than 2 times in a 20 min time period non-reactive - ABNORMAL FHR does not accelerate sufficiently with fetal movements

Answer 23

more invasive test used to measure FHR response to contractions, nipple stimulations or pitocin use to induce contractions can lead to preterm labor

Answer 24

nonreactive stress test, high risk pregnancies

Answer 25

Negative - normal finding. no late decelerations of FHR with three contractions in 10 mins positive - abnormal finding, late decelerations present in 50% or more contractions, may mean uteroplacental insufficiency

Answer 26

amniotic fluid is aspirated under ultrasound guidance performed after 14 weeks

Answer 27

high levels associated with neural tube defects, low levels associated with the chromosomal disorder empty bladder prior risks - amniotic fluid emboli, hemorrhage, infection, leakage of amniotic fluid, premature rupture of membranes, miscarriage

Answer 28

the portion of the placenta is aspirated through catheter to assess for chromosome abnormalities 10-13 weeks gestation provides earlier diagnosis can cause chorioamnionitis, premature rupture of membranes, miscarriage
