CCRN neonatal questions and answers
2026\2027 A+ Grade
Fetal fibronectin
- correct answer biochemical marker useful for predicting preterm birth within 2 weeks
placental α-microglobulin-1 (PAMG-1) protein
- correct answer presence indicates rupture of membranes
Fetal heart rate variability
- correct answer best indicator of fetal oxygenation status (absence of metabolic acidemia)
Biophysical profile
- correct answer -fetal tone
-fetal breathing
-fetal movement
-nonstress test
-amniotic fluid volume
Late decelerations
- correct answer transient response to hypoxemia during contractions
Variable decelerations
- correct answer cord compression
-tx: amnioinfusion, intrauterine pressure catheter
Maternal serum α-fetoprotein
- correct answer -Elevated: neural tube defect, abdominal wall defect, EA/duodenal atresia
, -Decreased: Down syndrome
Target preductal sat after birth
- correct answer -1 minute 60-65%
-2 minutes 65-70%
-3 minutes 70-75%
-4 minutes 75-80%
-5 minutes 80-85%
-10 minutes 85-90%
Arterial cord blood gas
- correct answer reveals the metabolic status of the fetus before delivery and strongly correlates with
perinatal asphyxia
