CNeoN(C) study guide
CNeoN(C) · Work through your exam, one topic at a time.
The Certified Neonatal Nurse (CNeoN) credential is a specialty certification for registered nurses who care for newborns, typically in level II–IV NICUs, delivery-room resuscitation teams, and newborn nurseries. It signals that a nurse has moved beyond general pediatric orientation and can reason independently about the fragile physiology of preterm and sick term infants. The CNeoN(C) study guide has 10 sections and about 3,003 words.
01Antepartum and Intrapartum Care of the High-Risk Mother and Fetus
High-risk care begins with risk stratification: maternal age, parity, chronic disease, prior pregnancy loss or preterm birth, multiple gestation, hypertensive and diabetic disorders, and fetal growth abnormalities. Understand antenatal surveillance tools - daily fetal movement counts, nonstress test (NST) reactivity, biophysical profile (BPP) scoring, and umbilical artery Doppler - and what each detects.
282 words, about 1 min02Resuscitation and Stabilization of the Newborn
The Neonatal Resuscitation Program (NRP) algorithm is the anchor: determine if the newborn is term, has good tone, and is breathing or crying. If yes, keep with mother for warmth and routine care.
280 words, about 1 min03Respiratory System
Neonatal respiratory disorders dominate this domain: respiratory distress syndrome (RDS) from surfactant deficiency, transient tachypnea of the newborn (TTN), meconium aspiration syndrome, and bronchopulmonary dysplasia. Understand signs of respiratory distress - tachypnea, grunting, nasal flaring, retractions, cyanosis - and the role of antenatal corticosteroids in accelerating surfactant production.
253 words, about 1 min04Cardiovascular System
Understand fetal circulation and the transition at birth: closure of the ductus arteriosus, foramen ovale, and ductus venosus, and how failure of these transitions produces persistent pulmonary hypertension of the newborn (PPHN). Know congenital heart lesions and their presentation: cyanotic (tetralogy of Fallot, transposition, tricuspid atresia) versus acyanotic (VSD, ASD, PDA, coarctation).
252 words, about 1 min05Neurologic and Sensory System
Focus on neonatal neurologic assessment: tone, reflexes (Moro, suck, rooting, grasp), level of alertness, and seizure recognition. Understand hypoxic-ischemic encephalopathy (HIE) and therapeutic hypothermia as the standard for eligible infants, including timing (within 6 hours) and eligibility criteria.
243 words, about 1 min06Gastrointestinal and Nutrition
Understand neonatal nutrition: colostrum and breast milk benefits, feeding cues, and the risks of feeding intolerance in preterm infants. Know necrotizing enterocolitis (NEC) - risk factors (prematurity, formula feeding, hypoxia), presentation (abdominal distension, bloody stools, feeding intolerance, lethargy), and management (stop feeds, decompress, antibiotics, surgery if perforation).
242 words, about 1 min07Renal and Metabolic Disorders
Understand neonatal fluid and electrolyte management, including insensible losses in preterm infants and the risk of hyperkalemia and hyponatremia. Know hypoglycemia - risk factors (infant of diabetic mother, preterm, small or large for gestational age, sepsis), symptoms (jitteriness, lethargy, poor feeding, apnea), and treatment thresholds and recheck intervals.
251 words, about 1 min08Hematologic and Immunologic Disorders
Understand physiologic anemia of infancy, anemia of prematurity, and the indications for transfusion. Know hemolytic disease of the newborn (Rh and ABO incompatibility), including the direct Coombs test, and the prevention of Rh sensitization with Rh immune globulin.
240 words, about 1 min09Infection and Sepsis
Know early-onset versus late-onset neonatal sepsis: early-onset (within 72 hours) is often from maternal genital tract organisms (group B Streptococcus, E. coli), while late-onset is often nosocomial or community-acquired.
240 words, about 1 min10Professional Practice
This domain covers scope of practice, standards of care, informed consent, documentation, delegation, and evidence-based practice. Understand the nurse's role in advocating for the patient, maintaining competence, and following institutional policy and professional standards.
