Maternity/Infant Health (Exam Two) Flashcards
List factors that place a pregnancy in the high-risk category.
- Genetic disorders
- Nutritional status
- Substance abuse
- Family history
- Environmental hazards
List the categories of risk for pregnancy.
- Biophysical
- Psychosocial
- Sociodemographic
- Environmental
List risk factors that may cause intrauterine growth restriction in a pregnancy.
- Poor nutrition
- Multifetal pregnancy
- Gestational hypertension
- Smoking
What antepartum test is used to monitor the fetus in pregnancies that are complicated by conditions that may affect oxygenation?
Daily fetal movement count (DFMC)
The nurse knows the physician will require what if a mother experiences fewer than three kicks in one hour?
Nonstress test (NST)
Diagnostic ultrasonography provides the health care provider with what critical information?
- Fetal activity
- Gestational age
- Fetal growth curves
- Fetal anatomy
- Placental anatomy
- Fetal well-being
- Visual assistance for more invasive testing
What diagnostic test could be performed to confirm a pregnancy or determine gestational age of the fetus?
Ultrasound examination
Transvaginal ultrasonography allows health care providers to evaluate what?
Pelvic anatomical features in greater detail
Intrauterine pregnancy may be diagnosed earlier using what diagnostic test?
Transvaginal ultrasonography
Doppler blood flow analysis is often associated with and used to confirm what fetal condition?
Intrauterine growth restriction (IUGR)
What diagnostic test allows the examiner to study the blood flow in the fetus and the placenta?
Doppler blood flow analysis
What is a biophysical profile?
Noninvasive dynamic assessment of a fetus based on acute and chronic markers of fetal disease
What fetal markers does a biophysical profile include?
HINT: Fetal vital signs
- Amniotic fluid volume
- Fetal breathing movement
- Fetal movement
- Fetal tone
- Fetal heart rate
What biophysical profile result is considered normal?
8 to 10 with normal amniotic fluid volume
Which trimester(s) is biophysical profile used most frequently?
Second and third trimesters
Why is the biophysical profile used most commonly in the second and third trimesters?
Most reliable indicator of fetal well being
List the major uses of ultrasonography in the first trimester?
- Confirm pregnancy
- Confirm viability
- Determine cause of vaginal bleeding
- Detect maternal abnormalities
The nurse knows an amniocentesis can be performed on a woman during what time frame of pregnancy?
After week 14 of pregnancy
List indications for performing an amniocentesis.
- Prenatal diagnosis of genetic disorders or congenital anomalies
- Assessment of pulmonary maturity
- Diagnosis of fetal hemolytic disorders
Assuming the amniotic fluid volume is adequate, what is the normal range for a biophysical profile score?
8 to 10
What is the most common reason for performing an amniocentesis?
Assess fetal lung maturity
During which trimester or weeks is the maternal serum alpha-fetoprotein (MSAFP) screening conducted?
From week 15 to week 20 of gestation
