2026 | 55 Original Questions | Answers and Teaching Rationales
Clinical judgment • Safety • Psychopharmacology • Therapeutic care • NGN formats

, Exam Blueprint and Directions
Domain Approx. emphasis
Safety, suicide, violence, crisis and legal/ethical care 24%
Therapeutic communication and milieu 18%
Mood, psychotic, anxiety, trauma and personality disorders 25%
Psychopharmacology and adverse reactions 20%
Substance use, cognitive and eating disorders 13%
Suggested simulation: Complete all 55 questions in one sitting. Select the single best answer unless the item says “Select
all that apply” or requests an ordered response. Apply ABCs, safety, least restrictive care, nursing process, and
acute-versus-chronic prioritization.
Scoring: This practice test uses raw percent correct. HESI uses a proprietary scaled score, so a raw percentage cannot be
converted reliably to an HESI score. ACI’s public 2025-2026 catalog identifies 850 as a benchmark in its EOC
readmission-exemption policy; your course syllabus may set a different requirement.
