RNC exam 2024/2025 QUESTIONS AND CORRECT
ANSWERS PROFESSOR VERIFIED
1. Fetal fibronectin (fFN): biochemical marker useful for predicting preterm birth
detected in vaginal secretions up until 22 weeks and then ~2 weeks before
delivery
2. Placenta a microglobulin 1 (PAMG1): glycoprotein in amniotic fluid
3. Amnisure test: detects PAMG1 via vaginal swab
4. maternal serum A-fetoprotein (MSAFP): high levels - neural tube, ventral
abdominal wall defects, esophageal/duodenal atresia; urinary tract anomalies
low levels - trisomy 21
5. Biophysical Profile (BPP): evaluates fetal well being via 5 variables: tone,
movement, breathing, reactivity (NST), amniotic fluid volume
6. nifedipine (procardia): calcium channel blocker, tocolytic proven to delay
delivery by 2-7 days to allow time for steroid administration
7. oligohydramnios: associated with fetal anomalies of renal and urinary
systems (ex. agenesis, LUTO)
8. polyhydramnios: result of impaired swallowing (ex. TEF), GI
anomalies/obstructions, or neurologic anomalies
9. chorioamnionitis: fever, tachycardia, uterine tenderness, foul-smelling
amniotic fluid, leukocytosis
, .
10. AED use during pregnancy: neural tube defects, heart disease, limb anom-
alies, intestinal atresias, cleft lip/palate
11. LBW definition: <2500 g
12. VLBW definition: <1,500 g
13. ELBW definition: 1,000 g
14. Babinski reflex: Reflex in which a newborn fans out the toes when the sole of
the foot is touched
15. Galant reflex: Stroking along one side of the spine while newborn is in ventral
suspension (face down) causes lateral flexion of lower body toward stimulated
side
16. Stepping reflex: a neonatal reflex in which an infant lifts first one leg and then
the other in a coordinated pattern like walking
17. scarf sign: position infant supine, pull hand across chest and around neck as
far as possible
Term: arms will meet resistance before crossing midline
Preterm: elbow will cross past midline without resistance
18. square window test: flex infant's hand on forearm between examiner's thumb
and index finger; measure angle between hypothenar eminence and. ventral
aspect of forearm
19. orolani & barlow test: assess for developmental hip dysplasia
20. erb duchenne palsy: internally rotated arm, pronated/flexed wrist, absent
moro results from excessive traction and stretching of brachial plexus nerves
21 Erb palsy: brachial plexus injury that can result from shoulder dystocia; arm
abducted and internally rotated, asymmetrical moro reflex; "waiter's tip" position
- extended elbow and wrist flexion
22. klumpe paralysis: swelling in shoulder and supraclavicular fossa, may be
accompanied by clavicle fracture
clawlike appearance of hand, no grasp of affected hand
