Week 2 - NURS 306 Practice Questions
All Answered Correctly 2026 Update.
Nurse's Role in Antepartal Tests - Answer - Provide information regarding the test
- Provide comfort
- Reassure the woman and her partner
- Provide psychological support to woman and her partner
- Document woman's response and the results of tests
Biophysical factors for high risk pregnancy - Answer - genetic factors
- originate from the mother or fetus and impact the development or function on the mother to
fetus
- include genetic, nutrition, medical. and obstetric issues
psychosocial factors for high risk pregnancy - Answer - maternal behaviors or lifestyles that
have a negative effect on the mother or fetus
- ex. smoking, caffeine use, alcohol/drug use, and psychological status
sociodemographic factors for high risk pregnancies - Answer - variables pertaining to the
woman and her family that place the mother and the fetus at increased risk
ex. assess to prenatal care, age, parity, marital status, income, and ethnicity
environmental factors for high risk pregnancies - Answer - hazards in the workplace or the
general environment that impact pregnancy outcomes
- various environmental substances can affect fetal fetal development
- ex. exposure to chemicals, radiation, and pollutants
Ultrasonography - Answer the use of high-frequency sound waves to produce an image of an
organ or tissue
standard ultrasound - Answer used for evaluating fetal presentation, amniotic fluid volume,
cardiac activity, placental position, gestational age measurements, and fetal number
,- usually done in the first trimester to confirm pregnancy or gestational age
- done in second or third trimesters, includes evaluation of fetal presentation, quantification of
amniotic fluid volume, documentation of presence or absence of cardiac activity, placental
position in relationship to the cervix, obtaining appropriate fetal biometric measurements, and
determining fetal number
limited ultrasound - Answer performed when a focused maternal/fetal ultrasound
assessment is indicated by the clinical situation. It can be used to measure amniotic fluid
volume, evaluate interval growth, evaluate the cervix, confirm fetal cardiac activity or fetal
presentation as an adjunct to ultrasound-guided amniocentesis or external version, confirm
embryonic number, measure crown-rump length, or confirm a yolk-sac or uterine sac with
assisted reproductive technology
specialized ultrasound - Answer used for targeted or detailed anatomic examination when an
anomaly is suspected based on fetal Doppler assessment, performance, or biophysical profile,
assessment of amniotic fluid, fetal echocardiography, or measurement of additional fetal
structures
transvaginal ultrasound - Answer ultrasound using a transducer inserted into the vagina to
view the internal female reproductive organs
- first trimester for early visualization
- lithotomy position
- sterile covered probe/transducer
abdominal ultrasound - Answer ● A full bladder is necessary to elevate the uterus out of the
pelvis for better visualization when performed during the first half of pregnancy.
● The woman is in a supine position.
● Transmission gel and transducer are placed on the maternal abdomen.
● The transducer is moved over the maternal abdomen to create an image of the structure
being evaluated
MRIs - Answer - a diagnostic radiological evaluation of tissue and organs from multiple
planes. During pregnancy, it is used to visualize maternal and/or fetal structures for detailed
imaging when screening tests indicate possible abnormalities. it is most commonly used for
suspected brain abnormality.
- woman is instructed to remove all metallic objects before the test
- the woman is placed in supine position with left lateral tilt on the MRI table
- the woman's abdominal area is scanned
, Umbilical Artery Doppler Flow - Answer noninvasive screening technique that uses advanced
ultrasound technology to assess resistance to blood flow in the placenta.
- it evaluates the rate and volume of blood flow through the placenta and umbilical cord vessels
using ultrasound
- assess placental perfusion
- supine position
- transmission gel and transducer and placed on abdomen
- the directed blood flow within the umbilical arteries is calculated using the difference between
systolic and diastolic flow
- as peripheral resistance increases, reversed end-diastolic flow can be seen with severe cases of
intrauterine growth restriction
- umbilical artery doppler is considered abnormal if the systolic/diastolic ratio is above the 95th
percentile for gestational age, or a ratio above 3.0, or end-diastolic flow is absent or reversed
Chorionic Villi Sampling - Answer a procedure in which the chorionic villi to are analyzed to
diagnose fetal genotypes. The aspiration of a small amount of placental tissue (chorionic villi)
for chromosomal, metabolic, or DNA testing
- Performed at 10-12 weeks to detect fetal abnormalities caused by genetic disorders
- tests for metabolic disorder like cystic fibrosis but not neural tube defects
- a catheter is inserted either transvaginally through the cervix or abdominally using a needle
- a small biopsy is removed with aspiration
- the villi are harvested and cultured for chromosomal analysis and processed for DNA and
enzymatic analysis as indicated
- Transvaginal or abdomen
- Sample sent for DNA analysis
- results in one week
- 7% fetal loss rate due to bleeding, infection, and rupture of membranes
- 10% of bleeding
- lithotomy for transvaginal aspiration
- supine for transabdominal aspiration
- give rhoGAM to rh negative women
Amniocentesis - Answer needle puncture of the amniotic sac to withdraw amniotic fluid for
analysis
- a diagnostic procedure in which a needle is inserted through the maternal abdominal wall into
the uterine cavity to obtain amniotic fluid
elevated bilirubin can indicate hemolytic disease
