HESI RN Dosage Calculations D441 Advanced Medication Math Assessment for WGU Nursing Students 2025 Edition

The HESI RN Dosage Calculations D441 exam is a specialized module within Western Governors University's (WGU) RN-to-BSN program (course code D441: Pharmacology), designed to validate competency in precise medication administration for aspiring registered nurses. This 50–60 question, 90-minute adaptive test focuses on computational skills essential for patient safety, including dosage conversions (e.g., mg/kg to mL), IV infusion rates (e.g., gtt/min using drop factors), parenteral and oral preparations, and specialized calculations like body surface area (BSA) for oncology drugs or neonatal dosing via Clark's rule. Aligned with NCLEX-RN blueprints, it incorporates real-world scenarios such as adjusting insulin sliding scales or TPN lipid emulsions, with emphasis on error detection and dimensional analysis methods. A minimum 80% pass rate is required for course completion; remediation includes rationales and formula sheets. Tailored for WGU's competency-based model, preparation resources like the HESI Pharmacology Case Studies, Quizlet banks (300+ questions), and apps such as Nurse Dosage Calculator help students achieve proficiency in 15–25 hours. Delivered via the HESI Compass platform, it's a pivotal tool fostering confidence in clinical pharmacology for diverse healthcare settings.
