ACLS and BLS are the most universally required certifications in acute care nursing. Unlike specialty certifications (CCRN, CEN, PCCN) that are voluntary and credential competency, BLS and ACLS are mandatory for employment in clinical settings that require them — you cannot work the first shift without them. Understanding what each certification involves, who needs which, and how to prepare effectively eliminates the anxiety most nursing students and new nurses feel about these exams.
| Certification | What It Covers | Who Needs It | Renewal | Typical Cost |
|---|---|---|---|---|
| BLS (Basic Life Support) | High-quality CPR for adults, children, and infants; AED use; relief of foreign body airway obstruction; 2-rescuer CPR | ALL clinical nurses and nursing students; required by virtually every acute care facility and most outpatient settings | Every 2 years | $30 to $80 if taken independently; often free through employer or nursing school |
| ACLS (Advanced Cardiovascular Life Support) | Management of cardiac arrest, peri-arrest arrhythmias, and unstable rhythms; systematic approach to respiratory arrest, stroke, ACS; ACLS algorithms and pharmacology (epinephrine, amiodarone, atropine, adenosine, etc.) | ICU, ED, cardiac step-down, telemetry, PACU, rapid response team nurses, procedural areas; any setting where resuscitation may be managed | Every 2 years | $150 to $300 if taken independently; often employer-paid |
| PALS (Pediatric Advanced Life Support) | Pediatric cardiac arrest and peri-arrest management; pediatric assessment (PAT); pediatric respiratory and shock management; weight-based pharmacology | PICU, NICU, pediatric ED, pediatric step-down nurses; any setting caring for critically ill children | Every 2 years | $150 to $300 if taken independently; often employer-paid |
| NRP (Neonatal Resuscitation Program) | Management of newborn resuscitation in the delivery room; bag-mask ventilation, intubation, umbilical catheter placement | L&D nurses, NICU nurses, nursery nurses; anyone who may be present at a delivery | Every 2 years | $150 to $250; often hospital-provided |
The AHA ACLS Provider course takes 1 to 2 days and covers the following core content areas:
Systematic cardiac arrest management: The ACLS approach to cardiac arrest is algorithmic — BLS Survey, ACLS Survey, CPR quality, rhythm-appropriate treatment (shockable vs non-shockable), reversible cause identification (the Hs and Ts). ACLS tests your ability to run a code as team leader and as team member, integrating these algorithms under pressure in timed scenarios.
Arrhythmia recognition and management: ACLS covers recognition and acute management of: ventricular fibrillation (VF), pulseless ventricular tachycardia (VT), pulseless electrical activity (PEA), asystole, stable and unstable narrow-complex tachycardia, stable and unstable wide-complex tachycardia, symptomatic bradycardia, and heart blocks requiring intervention. Each rhythm has a corresponding algorithm with pharmacological and electrical therapy decision points.
Pharmacology: ACLS medications, doses, and indications: epinephrine (1:10,000 IV/IO push every 3-5 minutes in arrest), amiodarone (300mg IV/IO for VF/pulseless VT, 150mg for stable VT), adenosine (6mg rapid IV push for stable SVT), atropine (1 mg IV for symptomatic bradycardia), dopamine and norepinephrine for post-arrest hemodynamic support, alteplase for massive PE or STEMI-related arrest.
Post-cardiac arrest care: ROSC (return of spontaneous circulation) management — targeted temperature management rationale, hemodynamic optimization targets (MAP >65), oxygenation targets (SpO2 92-98%), avoiding hyperoxia, immediate cardiac catheterization consideration for STEMI.
Acute stroke recognition: CPSS (Cincinnati Prehospital Stroke Scale), acute stroke management targets, tPA eligibility framework — time-sensitive recognition is the nurse's critical contribution.
ACLS is not a difficult exam for nurses who prepare specifically. The exam involves: a written multiple-choice test (50 questions, passing score typically 84%) and simulated scenario-based stations where participants demonstrate algorithm application. The scenarios are the part most nurses worry about — performing skills while being evaluated and verbalizing the algorithm simultaneously.
Learn the algorithms before the class: The AHA publishes all ACLS algorithms publicly. Nurses who arrive at the ACLS class having memorized the cardiac arrest algorithm, the tachycardia algorithm, and the bradycardia algorithm perform the scenario stations confidently. Those who try to learn algorithms for the first time during the class struggle.
Know your ACLS drugs cold: Epinephrine, amiodarone, adenosine, atropine — dose, route, indication, timing. The written exam and the scenario stations both test drug knowledge under time pressure. Make a drug card and review it before the class date.
Practice verbalizing while doing: ACLS scenario stations require simultaneously performing skills (compressions, defibrillator use, drug administration) and verbalizing the clinical reasoning. This feels awkward the first time. Practicing with a study partner — narrating what you're doing while you do it — removes the cognitive awkwardness before the class.
