CCRN, CEN & PCCN Study Guides

By Walter Dusseldorp · Updated June 12, 2026 · 20 free guides, no sign-up required

Every guide below is free and maps to the AACN (CCRN, PCCN) and BCEN (CEN) exam blueprints: a focused concept review, exam-style practice questions with full rationales, and the mistakes that cost real candidates points. Pick your exam and topic, then keep drilling with the free daily tools.

CCRN — Critical Care

• CCRN Hemodynamics Practice QuestionsFree CCRN hemodynamics practice questions with rationales: preload/afterload/contractility, MAP and CO/SVR, shock-state profiles, and reading CVP and arterial pressures.
• CCRN Cardiovascular Practice Questions (ACS, Heart Failure, Arrhythmias)Free CCRN cardiovascular practice questions with rationales: ACS and STEMI recognition, heart failure management, common arrhythmias, and post-arrest care priorities.
• CCRN Pulmonary & Ventilator Practice QuestionsFree CCRN pulmonary and mechanical ventilation practice questions: ARDS and lung-protective settings, ABG interpretation, vent alarms, ventilator-associated event prevention.
• CCRN Sepsis & Shock Practice QuestionsFree CCRN sepsis and shock practice questions: recognition and the sepsis bundle, lactate and fluid resuscitation, vasopressor selection, MODS, and distributive-shock physiology.
• CCRN Neurology Practice Questions (ICP, Stroke, Status Epilepticus)Free CCRN neurology practice questions: ICP and CPP management, herniation recognition, ischemic vs hemorrhagic stroke care, status epilepticus, and neuro assessment.
• CCRN Renal & Electrolyte Practice QuestionsFree CCRN renal and electrolyte practice questions: acute kidney injury, hyperkalemia and ECG changes, sodium disorders and correction risks, and continuous renal replacement basics.
• CCRN Multisystem & Endocrine Practice Questions (DKA, Adrenal, Tox)Free CCRN multisystem and endocrine practice questions: DKA and HHS management, the potassium trap, adrenal crisis, thyroid emergencies, and critical-care toxicology principles.
• CCRN Gastrointestinal & Hepatic Failure ReviewFree CCRN GI and hepatic practice questions: GI bleeding and resuscitation, acute liver failure and encephalopathy, pancreatitis, and abdominal compartment syndrome.
• CCRN Cardiac Surgery Recovery ReviewFree CCRN post-cardiac-surgery practice questions: bleeding and tamponade, chest tube management, low-cardiac-output state, pacing, and electrolyte/arrhythmia priorities.

CEN — Emergency Nursing

• CEN Triage Scenarios Review (ESI & Prioritization)Free CEN triage practice scenarios with rationales: the Emergency Severity Index, high-risk presentations, resource prediction, pediatric and geriatric red flags, and undertriage traps.
• CEN Cardiovascular Emergencies ReviewFree CEN cardiovascular practice questions: STEMI recognition and door-to-balloon, the unstable arrhythmia decision, aortic dissection, cardiac tamponade, and hypertensive crisis.
• CEN Respiratory Emergencies ReviewFree CEN respiratory practice questions: asthma and COPD exacerbations, the failing airway, pulmonary embolism, pneumothorax, and NIV versus intubation decisions.
• CEN Neurologic Emergencies ReviewFree CEN neurologic practice questions: stroke recognition and time windows, status epilepticus, the altered-mentation workup, meningitis, and increased ICP in the ED.
• CEN Trauma Emergencies ReviewFree CEN trauma practice questions: the primary survey, hemorrhage control and shock, head and chest injuries, the trauma triad of death, and special-population trauma.
• CEN Toxicologic & Environmental Emergencies ReviewFree CEN toxicology and environmental practice questions: overdose antidotes, toxidromes, decontamination, heat stroke and hypothermia, and carbon monoxide poisoning.
• CEN Shock & Sepsis Recognition ReviewFree CEN shock and sepsis practice questions: the four shock categories, early sepsis recognition and the bundle, lactate and fluid resuscitation, and distributive-shock pitfalls.

PCCN — Progressive Care

• PCCN Progressive Care Practice QuestionsFree PCCN practice questions: telemetry and arrhythmia recognition, heart failure and ACS on the floor, early-warning deterioration, and the progressive-care scope of practice.
• PCCN Arrhythmia & ECG Interpretation ReviewFree PCCN ECG and arrhythmia practice questions: a stepwise rhythm method, AV blocks, atrial fibrillation, ventricular rhythms, and the stable-versus-unstable decision.
• PCCN Respiratory Management ReviewFree PCCN respiratory practice questions: COPD and asthma management, oxygen titration, noninvasive ventilation on the floor, ABG basics, and recognizing respiratory failure.
• PCCN Electrolyte & Endocrine ReviewFree PCCN electrolyte and endocrine practice questions: potassium and the ECG, sodium correction safety, magnesium and arrhythmia, and diabetic emergencies on the floor.
