Adult CCRN Certification Exam Practice Questions | 2026/2027
Introduction
The Adult Critical Care Registered Nurse (CCRN) certification, administered by the American
Association of Critical-Care Nurses (AACN), is a prestigious credential that validates a nurse's
specialized knowledge and clinical competency in the care of acutely and critically ill adult
patients. This certification examination is aligned with the AACN Synergy Model for Patient Care
and tests clinical judgment across nine major content domains. Earning the CCRN designation
demonstrates advanced proficiency in evidence-based critical care practice and is widely
recognized as a benchmark of excellence in the nursing profession.
This comprehensive practice question guide contains 125 carefully crafted, evidence-based
questions covering all nine domains of the CCRN examination blueprint. Each question includes
four answer options with the correct answer clearly identified, followed by a detailed rationale
explaining the clinical reasoning behind the correct choice. The rationales reference current clinical
practice guidelines, landmark clinical trials, and foundational pathophysiologic principles. To
maximize the benefit of this study tool, we recommend answering each question independently
before reviewing the rationale, then revisiting any questions answered incorrectly after reviewing
the relevant content area.
The nine domains covered in this guide include: Cardiovascular Systems; Pulmonary Disorders;
Neurological Critical Care; Renal & Electrolyte Emergencies; Endocrine & Metabolic Crises;
Gastrointestinal & Hepatic Critical Care; Sepsis & Multi-System Organ Dysfunction;
Pharmacology in Critical Care; and Ethical/Legal Issues in Critical Care. These domains reflect the
breadth of knowledge required of a CCRN-certified nurse and encompass the most frequently
tested content areas on the certification examination. All content is intended for legitimate exam
preparation using evidence-based critical care guidelines, AACN Synergy Model frameworks, and
authorized study resources.
Domain 1: Cardiovascular Systems
ACS, Heart Failure, Arrhythmias, Hemodynamic Monitoring
1. A patient with an acute ST-elevation myocardial infarction (STEMI) arrives at the emergency
department. The 12-lead ECG shows ST elevation in leads II, III, and aVF. Which coronary artery
is most likely occluded?
A) Left anterior descending artery B) Right coronary artery
C) Left circumflex artery D) Left main coronary artery

Rationale: ST elevation in leads II, III, and aVF indicates an inferior wall MI, which is most commonly
caused by occlusion of the right coronary artery (RCA). The LAD supplies the anterior wall, the LCx
supplies the lateral wall, and left main occlusion would cause widespread ST changes.
2. A patient in cardiogenic shock has the following hemodynamic parameters: cardiac output 3.2
L/min, cardiac index 1.6 L/min/m², systemic vascular resistance (SVR) 1800 dynes·sec/cm⁵, and
pulmonary capillary wedge pressure (PCWP) 22 mmHg. Which intervention is the priority?
A) Administration of a vasodilator B) Administration of an inotrope
C) Fluid bolus of 500 mL normal saline D) Placement of an intra-aortic balloon pump
Rationale: The elevated PCWP (22 mmHg) indicates volume overload, and the elevated SVR (1800
dynes·sec/cm⁵) suggests vasoconstriction. However, the low cardiac index (1.6) with a high PCWP suggests
the patient is not fluid-responsive in a classic sense — but per current ACC/AHA cardiogenic shock
guidelines, carefully titrated fluid challenge should be attempted first unless there are clear signs of
pulmonary edema on exam. An inotrope like dobutamine would be the next step if the patient remains
hypoperfused after fluids. An IABP is no longer routinely recommended as first-line in cardiogenic shock per
the IABP-SHOCK II trial.
3. The nurse is caring for a patient who has just undergone percutaneous coronary intervention
(PCI) with femoral artery access. Which assessment finding requires immediate notification of the
provider?
A) Pedal pulse present but diminished compared B) Hematoma of 2 cm at the access site
to the contralateral leg
C) New-onset coolness and pallor of the D) Complaints of mild back discomfort
affected extremity
Rationale: New-onset coolness and pallor of the affected extremity suggests acute limb ischemia, potentially
from retroperitoneal bleeding, arterial dissection, or thrombosis. This is a vascular emergency requiring
immediate intervention. A diminished pulse and small hematoma are expected post-procedure findings that
warrant close monitoring but not emergent action.
4. A patient with acute decompensated heart failure is receiving continuous milrinone infusion.
Which electrolyte abnormality is most commonly associated with this medication and requires
close monitoring?
A) Hyperkalemia B) Hypokalemia
C) Hypercalcemia D) Hypomagnesemia
Rationale: Milrinone, a phosphodiesterase-3 (PDE-3) inhibitor, can cause hypotension and arrhythmias.
Hypomagnesemia is commonly associated with PDE-3 inhibitor use and predisposes the patient to
