CENP study guide
CENP · Work through your exam, one topic at a time.
The Certified Emergency Nurse Practitioner (CENP) credential is a specialty certification for nurse practitioners who practice in emergency care settings - freestanding EDs, hospital emergency departments, urgent care with emergency scope, and fast-track or observation units. It signals that an NP has met a national standard of knowledge beyond entry-level FNP or AGACNP preparation, and it is typically pursued by clinicians who already manage undifferentiated complaints, order and interpret point-of-care and advanced imaging, perform procedures, and disposition patients independently or in collaboration with a physician. The CENP study guide has 7 sections and about 2,155 words.
01Clinical Assessment, Diagnosis, and Diagnostic Reasoning
A focused history (onset, provocation, quality, radiation, severity, timing, associated symptoms, risk factors, medications) plus a targeted exam should generate a ranked differential within minutes. Expert reasoning is Bayesian: estimate pretest probability from age, comorbidity, and vital signs; choose the test that will move you across a management threshold; then act on post-test probability.

Priority is set by how fast treatment must start, not by how dramatic the presentation is: cardiac arrest, lost airway, anaphylaxis, tension pneumothorax, major hemorrhage, STEMI, stroke, sepsis, status epilepticus, DKA, and symptomatic electrolyte emergencies. Sepsis: cultures before antibiotics but never a delay that costs the patient; broad-spectrum antibiotics, about 30 mL/kg crystalloid for hypotension or lactate ≥4 mmol/L, then norepinephrine to a MAP goal of ≥65 mmHg.

X-ABCDE: control exsanguinating hemorrhage (direct pressure, tourniquet, wound packing, pelvic binder), then airway with cervical spine protection, breathing (breath sounds, oxygenation, needle decompression for tension physiology), circulation (two large-bore IVs, blood products), disability (GCS, pupils, glucose), exposure with active warming. Only after the primary survey and resuscitation do you move to the head-to-toe secondary survey, FAST, and imaging decisions.

Indication and alternatives, contraindications, informed consent (implied in a true emergency), a time-out confirming patient, site, and side, positioning, anesthesia, sterile technique, the procedure itself, confirmation of success, and documentation of complications and follow-up. Competence includes recognizing when to stop and call for help.

Weight-based dosing and equipment, age-specific vital signs, and a lower threshold for early escalation. Key patterns: the febrile infant younger than 28 days gets a full sepsis evaluation and admission; PECARN guides head imaging; bronchiolitis is supportive (no routine bronchodilators or steroids); croup responds to dexamethasone; dehydration is judged clinically.

EMTALA requires a medical screening examination and stabilizing treatment before any discussion of payment, and transfer only after certification of benefit and acceptance by a receiving facility; delays for insurance authorization are a classic violation. Consent requires capacity, information, and voluntariness; emergencies permit implied consent, and minors require parent or guardian consent except in defined situations such as emancipated minors or emergencies.

Every encounter is a chance to screen and intervene: tobacco and alcohol use (SBIRT), HIV and hepatitis C testing where indicated, intimate partner violence, depression (PHQ-2/9), fall risk, vaccine status including tetanus, influenza, and pneumococcal, and STI screening. Brief motivational interviewing outperforms a lecture, and a warm handoff referral closes the loop.
