prenatal 2 -preterm Flashcards
What is the significance of folic acid
reduce the rate of neural tube defects such as spina bifida
What is the appropriate amount of folic acid
400 mcg./day
What are the food sources for folic acid-4
Green leafy vegetables, liver, peanuts, and whole-grain breads and cereals.
What is the significance of iron
In prevention of iron deficiency anemia
What is the appropriate amount of iron
27 mg/day
What are the food sources for iron-8
Lean meats, dark green leafy vegetables, eggs, and whole-grain and enriched breads and cereals, dried fruits, legumes, shellfish, and molasses.
• What is the practice of pica
It is the craving for and persistent eating of nonnutritive substances, such as soil, clay, powdered laundry starch or corn starch, soap, baking powder, freezer frost, ice, charcoal, burnt matches, or ashes.
What are the clinical implications for a mother practicing pica?
May contribute to iron-deficiency or interfering with iron absorption.
In what manner would pica be assessed
History and non-judgmental attitude.
How would you teach a mother to assess fetal movement
Check twice a day. At least 10 movements in 3 hour period
What is the significance of fetal movement
Fetal activity provides reassurance of fetal well-being
What would you instruct the mother to do if fetal movement is adequate
Begin at 28 weeks on a daily basis.
What would you instruct the mother to do if fetal movement is inadequate
Consult physician immediately
• Amniocentesis. What is the purpose of this test in the first or second trimester
Detect fetal anomalies or neural tube defects or chromosomal
Amniocentesis. What is the purpose of this test in the 3T
Assess for lung maturity
What should the nurse teach the mother about the amniocentesis
report unusual fetal hyperactivity or lack of movement, vaginal discharge, uterine contractions or abdominal pain, fever or chills.
What is the non-stress test
What is meant by 15 x 15
A test to assess fetal well-being. A reactive test show at least two accelerations of FHR with fetal movements of 15 beats per minute, lasting 15 seconds or more.
When is a non-stress reactive or reassuring
Nonreactive test accelerations are not present or do not meet the above criteria indicating that the fetus is at risk or asleep
When is the non-stress nonreactive or non-reassuring
When the fetus is asleep or at risk.
What is the nurse’s response to a reactive non-stress test
Shows fetal well-being
What is the nurse’s response To a nonreactive non-stress test
Repeated for 20 minutes after stimulation
What is the contraction stress test
It is a means of evaluating the oxygen and carbon dioxide exchange of the placenta.
What is a negative contraction stress test
A negative CST shows 3 contractions of good quality lasting 40 or more seconds in 10 minutes
What is a positive contraction stress test
A positive CST shows repetitive late decelerations with more than 50 % of the contractions. This is bad
What is the nurse’s response to a positive contraction stress test
fetus will not withstand the stress of labor
-biophysical profile
What is the purpose for performing a biophysical profile
It is performed when there is a risk of placental insufficiency or fetal compromise
biophysical profile assesses-5
Fetal breathing movement, fetal movements of body or limbs, fetal tone, amniotic fluid volume (visualized as pockets of fluid around the fetus) and the 5th is reactive fetal heart rate with activity (reactive nonstress test (NST)
What two tests make up a biophysical profile
ultrasound and the nonstress test
What does the numeric score mean with biophysical profile
A score of 8 or 10 is normal
