If you care for patients before and after procedures in an ambulatory surgery center, a same-day surgery unit, or Phase II recovery, the Certified Ambulatory Perianesthesia Nurse (CAPA)® credential shows your knowledge goes beyond the basics. The exam is awarded by the American Board of Perianesthesia Nursing Certification (ABPANC), and it can feel intimidating because it covers the entire perianesthesia experience, from the pre-admission phone call to the discharge teaching.

The good news is that ABPANC publishes exactly what it tests. In this guide, we’ll walk you through the exam format, all five blueprint domains and their weights, the official resources worth downloading, and the questions candidates ask most often.

What Is the ABPANC CAPA Exam?

The CAPA is ABPANC’s certification for registered nurses who care for patients in the Preanesthesia Phase, Day of Surgery/Procedure, Postanesthesia Phase II, and Extended Care (sometimes called Phase III). Its sister credential, the Certified Post Anesthesia Nurse (CPAN)®, focuses on Postanesthesia Phase I. ABPANC’s simple rule is that your hours decide the exam: Phase I nurses fit the CPAN, and nurses working in the other perianesthesia phases fit the CAPA.

The exam is not a list of drug facts. Most questions describe a patient, a procedure, and an anesthetic, then ask what you should assess, prioritize, teach, or report. You need solid pharmacology and physiology, but you also need to apply them to realistic ambulatory situations.

What Is the CAPA Exam Format?

Here is the exam at a glance, based on the ABPANC Certification Candidate Handbook and the ABPANC exam information page:

  • Questions: 185 multiple-choice questions.
  • Scored vs. unscored: 140 scored questions plus 45 unscored pretest questions. The pretest items are mixed in, so treat every question as if it counts.
  • Time: Up to 3 hours. No breaks are scheduled, and any restroom time counts against your exam clock.
  • Delivery: Computer-based through PSI, at a PSI test center or by live remote proctoring from your own computer.
  • Testing windows: March 15 to May 15 and September 15 to November 15 each year.
  • Scoring: Scaled scores range from 200 to 800, and you need a 450 or higher to pass.
  • Results: Your score report is available as soon as you finish. Passing candidates see a pass notice without a number. Candidates who don’t pass receive a total scaled score plus scaled scores for each of the five domains.

With 180 minutes for 185 questions, you have a little under a minute per question. That is enough if you have practiced reading clinical stems efficiently, but it leaves little room to agonize over every item.

What Content Outline Does the CAPA Exam Use?

The current exam is based on the CAPA Exam Blueprint for testing beginning Spring 2023. ABPANC built it from a Role Delineation Study conducted in 2020 and 2021, and it states that the updated blueprints apply to exams from 2023 through 2027. Each domain lists “knowledge of” topics and the tasks a CAPA nurse performs.

Here is how the 140 scored questions break down. The approximate question counts come from our calculations based on ABPANC’s percentages.

  • Domain 1, Anesthesia: 20% (about 28 questions)
  • Domain 2, Physiology: 16% (about 22 questions)
  • Domain 3, Perianesthesia Monitoring and Intervention: 30% (about 42 questions)
  • Domain 4, Perianesthesia Care Considerations: 25% (about 35 questions)
  • Domain 5, Professional Nursing Practice and Guidelines: 9% (about 13 questions)

Domain 1: Anesthesia (20%)

This domain covers the anesthetics your patients receive and everything you do to get them safely to and through the procedure. Expect questions that ask you to anticipate recovery needs based on the anesthetic technique and the patient’s history.

  • Anesthesia techniques: general, regional, local, moderate sedation, and monitored anesthesia care (MAC) and total intravenous anesthesia (TIVA).
  • Anesthetic and reversal agents, and the stages of anesthesia.
  • Special populations: pediatric, pregnant, geriatric, and patients with pre-existing conditions.
  • Tasks such as confirming identity, consent, and the expected procedure; reviewing history, allergies, medications, and supplements; reviewing clearance documents and diagnostic results; and preparing emergency equipment.
  • Administering medications before and after the procedure, protecting the patient from positioning and thermal injury, and managing recovery from anesthesia.

Study tip: Know your reversal agents cold, including naloxone for opioids, flumazenil for benzodiazepines, and sugammadex or neostigmine with glycopyrrolate for neuromuscular blockade, plus the resedation risk when a reversal agent wears off before the drug it reversed.

Domain 2: Physiology (16%)

Physiology is about how body systems respond to surgery and anesthesia, and how pre-existing conditions change that response. It starts at pre-admission screening, where you identify problems before the day of surgery.

  • Pathophysiology of body systems, physical assessment, and physical responses to procedures and anesthesia.
  • Potential complications of pre-existing conditions, such as obstructive sleep apnea, diabetes, and heart disease.
  • Conducting a physical assessment and pre-admission screening.
  • Maintaining respiratory, cardiovascular and peripheral vascular, neurological, musculoskeletal, gastrointestinal, renal/genitourinary, integumentary, endocrine, and hematologic and immune function, plus fluid and electrolyte balance and temperature.

What questions look like: A screening call reveals a patient with diabetes who takes a GLP-1 receptor agonist or an SGLT2 inhibitor. The question tests whether you recognize the anesthesia implication (aspiration risk or euglycemic ketoacidosis) and escalate it per protocol.

Domain 3: Perianesthesia Monitoring and Intervention (30%)

This is the largest domain, and it is where clinical judgment matters most. It covers what you watch for after the procedure and how you respond when something goes wrong.

  • Vital signs and hemodynamic monitoring, normal and abnormal diagnostic results, and airway management.
  • Complications with emergence, abnormal physiological conditions, thermoregulation, and fluid and electrolyte management.
  • Acute and chronic pain management, non-pharmacological modalities, and postoperative nausea and vomiting (PONV).
  • Pharmacology, pharmacodynamics, pharmacokinetics, and interactions with medications or supplements.
  • Tasks such as evaluating sedation level, managing pain and comfort, maintaining lines and drains, administering blood products, and recognizing and responding to perianesthesia-specific emergencies such as malignant hyperthermia and laryngospasm.

Study tip: Practice prioritization. Many questions offer several reasonable actions, and the best answer is usually the one that addresses airway, breathing, or circulation first.

Domain 4: Perianesthesia Care Considerations (25%)

This domain is central to ambulatory nursing. It covers the continuum of care, individualized care, and the teaching that lets patients recover safely at home.

  • The continuum and transfer of care: pre-admission, pre-operative (day of surgery), Postanesthesia Phase I, and Postanesthesia Phase II.
  • Individualized care that accounts for environmental, psychosocial, behavioral health, and mental health factors.
  • Handoff communication, safe transport, and a multidisciplinary plan of care developed with the patient and caregivers.
  • Pre-admission education on medications, allergies, and preparation, and verbal and written discharge education on pain management, wound and drain care, warning signs, infection prevention, and caregiver and transportation availability.
  • Psychosocial support, referrals, and evaluating whether teaching was effective.

What questions look like: A patient who received sedation is ready for discharge, but their ride fell through. The best answer protects the patient, even if it delays discharge.

Domain 5: Professional Nursing Practice and Guidelines (9%)

The smallest domain covers the standards that shape perianesthesia practice. It is only about 13 questions, but they are often quick points if you know the source documents.

  • American Society of PeriAnesthesia Nurses (ASPAN) standards and American Society of Anesthesiologists (ASA) guidelines.
  • ACLS and PALS guidelines, and the Malignant Hyperthermia Association of the United States (MHAUS) protocol.
  • Evidence-based practice, healthcare quality and patient safety principles, and regulatory, legal, and ethical guidelines.
  • Tasks such as documenting care to national standards, collaborating with the multidisciplinary team, and protecting privacy and confidentiality.

How Should You Use the CAPA Blueprint to Build a Study Plan?

Treat the blueprint as your master checklist. Turn each knowledge topic into a question you can answer without notes, and rate it as strong, developing, or weak.

  1. Take a mixed baseline. Answer a set of questions across all five domains before you start reviewing so you know where you actually stand.
  2. Weight your time. Domains 3 and 4 make up 55% of the scored exam, so weaknesses there cost the most.
  3. Map every miss. Tie each missed question to a blueprint topic, such as “PONV” or “discharge education,” rather than just noting the domain.
  4. Don’t skip the small domains. Domain 5 is only 9%, but standards questions are quick to study and easy to lose.
  5. Finish with mixed, timed practice. In the last few weeks, practice at roughly one minute per question.

Frequently Asked Questions About the ABPANC CAPA Exam

What score do I need to pass the CAPA exam?
You need a scaled score of 450 or higher on a scale of 200 to 800. ABPANC reports scaled scores, not a percentage correct.

How hard is the CAPA exam?
It’s a demanding exam because questions ask you to apply perianesthesia knowledge to patient scenarios, not just recall facts. Most candidates benefit from several months of structured preparation, even with years of experience.

When will I get my results?
Immediately. Your final score report is available in your account as soon as you finish the exam.

Can I retake the exam if I don’t pass?
Yes. You can test once per testing window, with no limit on the number of windows. ABPANC’s optional Test Assured program ($50 when you register) lets you retake the exam in either of the next two windows without paying the exam fee again.

How long is the CAPA certification valid?
Three years. To recertify, you need at least 900 hours of perianesthesia nursing practice plus either 70 perianesthesia-related contact hours or a passing exam score.
