AACN Certification Corporation · Adult CCRN Test Plan effective for examinations taken on and after November 12, 2025, verified in the July 2026 CCRN Exam Handbook—Direct Care Eligibility Pathway. Reviewed for 2026-10-11, Asia/Hong_Kong. The workbook label 'Critical Care Registered Nurse' maps to the CCRN certification brand; AACN expressly states that CCRN is not an acronym for that phrase. This preview explicitly covers the verified adult examination, since the workbook label does not specify a patient population. The assigned slug is preserved.

This original 20-question sample covers selected topics across the outline. It does not reproduce official exam questions or cover every tested topic.
