Q

Non-stress test

  1. what is it
  2. normal finding
  3. abnormal
  4. positioning the client
  5. intervention if no accelerations
A
  1. noninvasive way of monitoring response of FHR to fetal movement
  2. a normal finding is 2 or more accelerations (increase in FHR of atleast 15 that lasts 15 seconds) within a 20 minute period
  3. does not do above. Indication of Contraction stress test (CST) or biophysical profile (BPP)
  4. semi fowlers or left lateral
  5. give a snack

Q

Contraction stress test

  1. methods
  2. indications
  3. normal finding
  4. abnormal finding
A
  1. nipple stimulation or oxytocin IV
  2. non reactive NST
  3. negative = 3 contractions over 10 mins with no decelerations
  4. a positive CST = late decelerations occur with 50% of contractions is suggestive of uteroplacental insufficiency

Q

Biophysical profile

  1. what is it
  2. normal vs abnormal
A
  1. uses ultrasound to visualize physiological characteristics of fetus. A score of 0 or 2 is given for each category
  2. (a)breathing: 1 episode of 30 seconds in 30 mins
    (b) gross body movements-atleast 3 body or limb extensions with return to flexion in 30 mins
    (c) fetal tone: atleast 1 episode of extension with return to flexion
    (d) reactive NST
    (e) amniotic fluid volume:atleast 1 pocket of fluid greater then or equal to 2 cm or more then 5 cm total

Q

Amniocentesis

  1. what can it do
  2. when is it done
  3. why would it be done in late pregnancy
A
  1. detects presence of AChe in neural tube defects and can identify genetic diseases (trisomy 21, 18, 13)
  2. performed at 14-16 weeks
  3. assess fetal lung maturity LLS ratio of 2:1 indicates fetal lung maturity

24
Q

pathologic vs physiologic jaundice

A

pathologic jaundice occurs before 24 hours or is persistant for more than 7 days. It indicates increased RBC production or breakdown. This is usually caused by ABO or Rh incompatibility or infection

25
Q

1.app

A

also known as genital warts

Q

common site for IM injection for kids

A

vastus lateralis

27
Q

should parents share rooms with new born babies

A

28
Q

what should you cover a baby with during sleep
