Answers Graded A+
amniocentesis -
correct answer ✅needle puncture of the amniotic sac to
withdraw amniotic fluid for analysis
- screens for chromosomal abnormalities
- typically performed early in 2nd trimester (15-20 wks), more
accurate >20 wks d/t chromosomal presence in fluid
- **also can be used later in pregnancy to assess fetal lung
maturity**
- often recommended for AMA
thrombocytopenia (maternal) -
correct answer ✅- a generally benign maternal medical
complication that is due to hemodilution (increased RBCs)
- may be associated with hypertensive conditions r/t pregnancy
- may be associated with s/s of bleeding in the infant
risks of maternal thrombocytopenia -
correct answer ✅can result in:
- increased risk of bleeding in the mother, especially during the
delivery
- **bleeding in the infant (oozing from umbilical cord, prolonged
bleeding from heel sticks, bruising, **petechiae
,RNC-NIC Exam Questions with Correct
Answers Graded A+
neonatal petechiae -
correct answer ✅- must consider
hyperbilirubinemia/jaundice (breakdown of RBCs)
- also associated with maternal thrombocytopenia
cytomegalovirus (CMV) -
correct answer ✅- **most common intrauterine infection**
- transmitted by exposure to infected blood or body fluids
- majority of infants asymptomatic at birth, but 5-15% have later
sequelae (most commonly hearing and vision loss)
contraindication for breastfeeding -
correct answer ✅- maternal HIV/AIDS infection
- **HIV/AIDS can be spread through breastfeeding**
signs of HIV in newborn -
correct answer ✅- poor weight gain
- **repeated fungal mouth infections** (thrush)
- enlarged lymph nodes
- enlarged liver/spleen
,RNC-NIC Exam Questions with Correct
Answers Graded A+
- neurologic problems
- multiple bacterial infections, including pneumonia
chlamydia -
correct answer ✅- **most common bacterial sexually
transmitted infection**
- *treatment: erythromycin*
signs/symptoms of neonatal chlamydia -
correct answer ✅- conjunctivitis in first few weeks
- late-onset: pneumonia at 3-4 months
- otitis media
- gastroenteritis
oligohydramnios -
correct answer ✅- AF volume <1 L at 36 weeks, <800 mL at
term
- can lead to pulmonary hypoplasia d/t amniotic fluid's role in fetal
pulmonary development
, RNC-NIC Exam Questions with Correct
Answers Graded A+
- **may be related to Potter sequence/renal agenesis** because AF
is largely made up of fetal urine (no urine if the baby has no
kidneys)
- **can lead to hypoplastic lungs**
- can also lead to IUGR and positional deformities (baby can't move
well)
Potter sequence (renal agenesis) -
correct answer ✅- **Renal agenesis -> oligohydramnios ->
severe pulmonary hypoplasia**
- association of defects beginning w/ bilateral renal agenesis d/t
failure of the ureteric bud to divide
- urine formation does not occur --> low or absent amniotic fluid
volumes
- fetal structures are compressed
- associated defects: abnormal genital dev., leg deformities, GI
defects, arthrohyposis, pulmonary hypoplasia
- *most infants will die within the first several days; often d/t
associated lung hypoplasia*
hydramnios or polyhydramnios -
correct answer ✅- AF volume >2L
