ca-cna-critical-care-pediatrics · Work through your exam, one topic at a time.
The Certified Neuroscience Nurse - Critical Care Pediatrics (CNA) credential is a specialty certification for registered nurses who care for infants and children with neurological and neurosurgical critical illness. Candidates typically work in pediatric intensive care units, neurotrauma units, or dedicated pediatric neuro-ICUs, and hold a foundational critical care background before pursuing this focused credential. The ca-cna-critical-care-pediatrics study guide has 10 sections and about 2,550 words.
01Neurological Assessment and Monitoring in the Critically Ill Child
Neurologic assessment of the critically ill child rests on serial, reproducible examinations rather than a single snapshot. Master the Pediatric Glasgow Coma Scale (eye, verbal, motor, age-adjusted for preverbal children), pupillary size and reactivity, brainstem reflexes (corneal, oculocephalic, gag), respiratory pattern, and motor asymmetry.
293 words, about 1 min02Traumatic Brain Injury and Spinal Cord Injury
Distinguish focal (contusion, hematoma) from diffuse (axonal) injury and primary from secondary injury. Secondary injury prevention is the nurse's core role: avoid hypoxia and hypotension (the two strongest predictors of poor outcome), maintain normocapnia, control fever, prevent hyperglycemia, and position to optimize venous drainage with head of bed about 30 degrees and midline head.
280 words, about 1 min03Seizures and Status Epilepticus
Status epilepticus is a seizure lasting about 5 minutes or recurrent seizures without recovery of consciousness. Recognize that critically ill children often have nonconvulsive seizures, detectable only by EEG, especially after cardiac arrest, in encephalitis, or with unexplained persistent coma.
261 words, about 1 min04Intracranial Hypertension, Hydrocephalus, and CSF Disorders
Intracranial hypertension results when the volume of brain, blood, and CSF exceeds the fixed cranial vault. Understand the pressure-volume curve: compliance is exhausted before pressure rises steeply, so deterioration can be sudden.
266 words, about 1 min05Cerebrovascular Disorders and Neurocritical Care Emergencies
Understand pediatric ischemic stroke (sickle cell disease, congenital heart disease, arteriopathy, dissection), hemorrhagic stroke (AVM, aneurysm), cerebral venous sinus thrombosis, and hypoxic-ischemic encephalopathy after cardiac arrest. Recognize that pediatric stroke often presents with seizure or focal deficit rather than classic adult signs, and that time to recognition matters because reperfusion windows exist.
247 words, about 1 min06Central Nervous System Infections
Master bacterial meningitis, viral encephalitis, brain abscess, and shunt infection. Recognize fever, headache, neck stiffness, photophobia, altered mental status, and seizures; infants may show only poor feeding, irritability, or a bulging fontanel.
256 words, about 1 min07Neurodevelopmental and Neuromuscular Disorders in Critical Care
Know Guillain-Barré syndrome (ascending weakness, areflexia, albuminocytologic dissociation), myasthenia gravis and crisis (fatigable weakness, ptosis, respiratory failure), and spinal muscular atrophy. Recognize that respiratory failure may precede limb weakness, so monitor vital capacity, negative inspiratory force, and cough strength rather than relying on oxygen saturation alone.
236 words, about 1 min08Neuropharmacology and Sedation/Analgesia
Understand that analgesia and sedation are distinct goals, that untreated pain and agitation raise ICP and oxygen demand, and that oversedation masks neurologic change and prolongs ventilation. Know common agents: opioids (fentanyl, morphine) for analgesia; benzodiazepines (midazolam) for sedation and seizures; propofol for short-term sedation with infusion-syndrome risk; dexmedetomidine for cooperative sedation with bradycardia and hypotension risk; ketamine with hemodynamic stability and ICP considerations.
219 words, about 1 min09Neuroimaging, Neurodiagnostics, and Multimodal Monitoring
Know when to choose CT (fast, detects hemorrhage and fracture, radiation exposure) versus MRI (superior for ischemia, infection, edema, and posterior fossa). Recognize that a normal early CT does not exclude ischemia or raised ICP.
242 words, about 1 min10Family-Centered Care, Ethics, and Rehabilitation/Transition Planning
Recognize parents as essential partners who know the child's baseline, communication style, and values. Practice clear, honest, developmentally appropriate communication with the child and family, shared decision-making, and support for siblings.
