““Clear questions that helped me review essential critical care concepts.””
Sunaina K
Critical Care Nurse
The CCRN (Adult) is not a test of whether you can do your job. You already do it. It tests whether you can pick the single best answer from four defensible-looking options while a clock runs. Practicing that skill is what this page is for.
The questions here are built around AACN's published adult test plan, with explanations that walk through why the correct answer wins and why the tempting alternatives lose.
The exam is 150 multiple-choice questions in 3 hours. Only 125 are scored. The other 25 are unscored pretest items AACN is trying out for future forms, and nothing marks which ones they are. Treat every question as if it counts. The math works out to a little over a minute per question, which is comfortable if you're decisive and tight if you second-guess yourself.
You can sit the exam at a PSI test center or through PSI's live remote proctoring from home. Results show on screen when you finish.

You need a current, unencumbered U.S. RN or APRN license and one of two clinical-hour options:
Two-year option: 1,750 hours of direct care of acutely/critically ill adult patients in the previous two years, with 875 of those in the most recent year.
Five-year option: at least 2,000 hours of direct care in the previous five years, with 144 of those in the most recent year.
Hours must be verifiable by a clinical supervisor or a professional colleague (RN or physician), because AACN audits applications. Managers, educators, preceptors and APRNs can count hours spent supervising nurses or students at the bedside. Most of your hours must involve critically ill patients, not just any adult inpatients. If your role is mostly leadership or education without bedside hours, look at AACN's Knowledge Professional pathway instead.
AACN's adult test plan splits the exam into clinical judgment (80%) and professional caring and ethical practice (20%). Clinical judgment is divided by body system.
Area | Weight |
|---|---|
Cardiovascular | 17% |
Pulmonary | 15% |
Endocrine, hematology, gastrointestinal, renal, integumentary | 20% |
Musculoskeletal, neurological, psychosocial | 14% |
Multisystem | 14% |
Professional caring and ethical practice | 20% |
AACN notes that the order of content in the plan does not reflect importance, and individual forms can drift a point or two from these figures. Some third-party guides quote slightly different percentages for cardiovascular. Use the current test plan in AACN's Direct Care exam handbook as the final word.
This section is informed guidance from how the blueprint is structured and how ICU nurses commonly describe their prep, not an official AACN statement.
The 20% block that isn't cardiac or respiratory. Endocrine, hematology, GI, renal and integumentary is the single largest clinical-judgment slice, yet most bedside nurses study it last because it feels like "everyone else's" content. A cardiac ICU nurse who can titrate any drip in her sleep can still lose easy points on DKA versus HHS management, HIT and DIC, upper GI bleeds, acute kidney injury and CRRT, or burn and wound care. This combined area is broad, so it rewards steady coverage rather than a cram.
Hemodynamics as a thread, not a topic. Preload, afterload, contractility, SVR, cardiac output and the numbers that go with them show up inside shock, sepsis, heart failure and postoperative cardiac questions. Weakness here quietly drags down several categories at once.
Acid-base and ventilator logic. Reading an ABG is a given. What trips people up is the next step: which vent change addresses this problem, what a rising plateau pressure is telling you, when the patient is failing a weaning trial.
Professional caring and ethical practice. Twenty percent is a fifth of the exam, and it's the area experienced nurses tend to answer by gut. The Synergy Model, advocacy, moral agency, collaboration, systems thinking and clinical inquiry questions have a "most patient-centered, most collaborative, most ethically sound" flavor that isn't always the same as what your unit does on a busy night. Learn to answer the way the framework wants, even where your workplace habits differ.
Multisystem. Sepsis, multiple organ dysfunction, toxicology, end-of-life and palliative care questions ask you to prioritize across failing systems. That is harder than answering a single-system question and deserves its own practice sessions.
CCRN questions are mostly clinical scenarios, not definitions. You'll get a patient, a set of findings, and a question along the lines of "what should the nurse do first?" or "which finding requires immediate action?" That format changes how you should practice.
Read the last line first. Knowing whether the question wants a priority, an interpretation, or an intervention tells you how to read the vignette.
Commit before you look. Choose an answer, then read the explanation. Peeking dilutes the practice.
Review the wrong answers you got right. If you guessed correctly, you don't own that concept yet.
Sort misses by cause. Was it a knowledge gap, a misread stem, or overthinking? Each fix is different. Knowledge gaps need content review, misreads need slower stem reading, and overthinking usually needs timed sets.
Practice by system first, then mix. Early on, block by area to expose weak spots. In the last two weeks, mix everything and run timed sets of 50 to 75 questions so switching from renal to ethics doesn't cost you a beat.
Do at least one full-length, 150-question sitting. Stamina over three hours is a genuine factor, and you can only learn your pacing by testing it.
AACN also sells its own practice exams. Using a second source is sensible, since different question writers phrase things differently.Start your National Council Licensure Examination for Practical Nurses(NCLEX-PN) exam practice today.
Studying only your home unit. A CVICU nurse who skims neuro and a neuro ICU nurse who skims cardiac both leave points on the table.
Treating hospital practice as the answer key. Where your unit's protocol differs from the evidence-based answer, the exam wants the evidence-based one.
Skipping the professional caring section. It's worth 20%, and it's the easiest area to pick up points with deliberate practice.
Ignoring the score report. After a first attempt, AACN's diagnostic report tells you where you fell short. Retakers who restart from page one waste weeks.
Rushing the retest. The fact that you can attempt up to four times in 12 months doesn't mean you should retest before the gap is closed.
Running out of time on the back half. With 150 questions, spending ninety seconds on early items leaves a crunch at the end. Flag and move on.
These ranges are practical guidance, not a vendor recommendation. Many ICU nurses report roughly six to ten weeks of steady prep, but yours will vary with how recently you've touched each system.
Starting point | Suggested runway | What to prioritize |
|---|---|---|
Newer to critical care (just past the hour requirement) | 10 to 14 weeks | Build systems coverage first. Focus on the areas outside your unit's specialty, then hemodynamics and ventilation. |
Experienced ICU nurse with broad exposure | 6 to 8 weeks | Take a diagnostic set early, then spend most time on your two weakest areas and on professional caring. |
Specialty-unit nurse (single-system ICU) | 8 to 10 weeks | Deliberately front-load the systems you rarely see. |
Retaking after a non-pass | 4 to 8 weeks | Use the AACN score report, retarget only the weak areas, and do timed mixed sets. |
The CCRN adult exam has been stable in structure: 150 items, 3 hours, 80/20 split between clinical judgment and professional caring. The one notable change to watch is the passing standard. Secondary sources report that AACN lowered the raw cut score from 87 to 83 out of 125 scored questions in November 2025, and AACN resets cut scores when forms are updated. Verify the current figure with AACN before test day rather than aiming for a percentage.
