HESI RN Dosage Calculations Exam Core Medication Math Proficiency for Nursing Excellence 2025 Edition

The HESI RN Dosage Calculations exam, offered by Elsevier's Health Education Systems Incorporated (HESI), is a pivotal 55-question, 90-minute assessment validating Registered Nursing (RN) students' ability to perform accurate drug computations for safe patient care. This adaptive multiple-choice and calculation-based test encompasses oral/parenteral dosages, IV infusion rates (e.g., gtt/min = (volume × drop factor) / time), heparin drips, body surface area (BSA) for oncology, and pediatric dosing via formulas like Young's rule. It stresses NCLEX-RN-aligned error prevention, dimensional analysis, and clinical scenarios such as insulin conversions (e.g., 1:100 dilution) or TPN lipid emulsions. A 90%+ score is standard for progression in ADN/BSN programs; detailed rationales aid remediation. Suited for foundational pharmacology courses, preparation includes HESI Case Studies, Quizlet (200+ questions), and apps like MedCalc in 10–15 hours, with users reporting 95% mastery. Accessible via HESI Compass, it's indispensable for med-surg, ICU, or pediatrics rotations.
