CPEN study guide
CPEN · Work through your exam, one topic at a time.
The Certified Pediatric Emergency Nurse (CPEN®) credential is a specialty nursing certification from the Board of Certification for Emergency Nursing (BCEN) for registered nurses who care for children in emergency settings. BCEN describes CPEN as the foundational specialty certification for RNs who treat pediatric patients in the emergency department, spanning care from the neonatal period through adolescence. The CPEN study guide has 10 sections and about 3,157 words.
01Cardiovascular Emergencies in the Pediatric Patient
Pediatric cardiovascular collapse is usually the end-stage of respiratory or hypovolemic failure, so the exam repeatedly tests recognition of compensated shock before hypotension appears . A child maintains blood pressure by increasing heart rate and systemic vascular resistance; hypotension is a late, pre-arrest finding.
322 words, about 2 min02Respiratory Emergencies and Airway Management
Respiratory failure remains the most common pathway to pediatric cardiopulmonary arrest. Assess using the pediatric assessment triangle (appearance, work of breathing, circulation) and then quantitate work of breathing: tachypnea, nasal flaring, suprasternal and intercostal retractions, grunting, head bobbing, and accessory muscle use.
316 words, about 2 min03Neurological Emergencies and Altered Mental Status
The pediatric neurological exam is anchored in serial reassessments rather than a single snapshot. Use AVPU or the age-appropriate Glasgow Coma Scale and document pupils, symmetry, and posturing.
307 words, about 2 min04Gastrointestinal Emergencies
Pediatric abdominal complaints demand attention to age-specific diagnoses and to volume status. Vomiting and diarrhea cause most dehydration; classify dehydration clinically (mild under 5%, moderate 5–10%, severe over 10%) using mental status, mucous membranes, tears, capillary refill, skin turgor, and heart rate.
307 words, about 2 min05Genitourinary Emergencies
Genitourinary complaints in children are frequently time-sensitive or presentationally subtle. The febrile infant is the classic trap: under 2–3 months, fever without a source requires a full sepsis evaluation including urinalysis, blood cultures, and empiric antibiotics.
326 words, about 2 min06Musculoskeletal Emergencies and the Limping Child
Musculoskeletal complaints require a systematic approach: inspect for swelling, deformity, and symmetry; palpate; and always perform a neurovascular and vascular exam distal to the injury , documenting it before and after any intervention. Pediatric fractures differ from adult ones because of the physis and the thick periosteum.
316 words, about 2 min07Integumentary Emergencies and Wound Care
Skin findings in children are common, but the emergency nurse must separate benign rashes from life-threatening eruptions and from injury patterns that suggest abuse. In burn care, estimate total body surface area using pediatric proportions: the infant head is roughly 18% and each leg about 14%, unlike adults.
328 words, about 2 min08Hematology and Oncology Emergencies
The hematology/oncology patient can decompensate in ways that look like common childhood illness, so build a habit of asking about the underlying diagnosis and recent therapy. In sickle cell disease , know the five crises: vaso-occlusive pain, acute chest syndrome, splenic sequestration, aplastic crisis, and stroke.
298 words, about 1 min09Endocrine and Metabolic Emergencies
Endocrine emergencies in children are often mistaken for gastroenteritis or sepsis. Diabetic ketoacidosis presents with polyuria, polydipsia, vomiting, abdominal pain, Kussmaul respirations, and dehydration; confirm with hyperglycemia, acidosis, and ketones.
307 words, about 2 min10Psychosocial and Behavioral Emergencies
Psychosocial care is tested as concrete, observable nursing behavior rather than abstract theory. Anchor practice in family-centered, developmentally appropriate care : explain procedures in the child's language, offer choices, use child life specialists, and minimize separation from caregivers.
