HESI Comprehensive Review for the NCLEX-PN 5th Edition 2026 (300+ Q&A) – HESI A Fundamentals – Medication Safety, Clinical Skills & Prioritization

This document contains over 300 expert-verified question-and-answer items from HESI Comprehensive Review for the NCLEX-PN®, 5th Edition – HESI A Fundamentals (2) 2026, designed to prepare practical nursing students for the NCLEX-PN licensure examination . The material is structured in a concise Q&A format and focuses heavily on foundational nursing concepts including medication administration safety, client assessment, documentation accuracy, infection control, and prioritization of care. The content emphasizes medication safety principles beyond the “five rights,” such as verifying the prescriber’s signature, understanding contraindications for sustained-release medications via NG tube, and recognizing appropriate documentation practices. It reviews orientation assessment findings (e.g., documenting disorientation), correct infection control techniques (avoiding contamination during catheter care), pre-test screening for fecal occult blood tests (vitamin C intake), and proper completion of incident reports by the PN involved in the event. Vital sign interpretation and clinical judgment are reinforced through applied scenarios, including irregular radial pulse assessment requiring apical pulse verification, Snellen chart testing procedures (covering the opposite eye), identification of purulent sputum as a concerning finding in immunosuppressed clients, recognition of hyperthermia postoperatively as an urgent finding, early signs of hypoxia (elevated blood pressure), orthostatic hypotension interventions (flexing feet before standing), and monitoring sodium levels for clients on prolonged NG suction. The review integrates core nursing skills such as fluid measurement conversions (5 mL per teaspoon), catheter positioning standards (drainage bag below bladder level), medication administration routes, laboratory monitoring, and postoperative complication recognition. The applied clinical scenarios mirror NCLEX-style questioning, reinforcing safety, delegation, scope of practice, and evidence-based nursing interventions. This resource is particularly relevant for Practical Nursing (PN) students preparing for the NCLEX-PN exam, LPN/LVN candidates completing fundamentals coursework, nursing students in remediation programs, repeat NCLEX test takers, and PN-to-RN bridge students reviewing core foundational concepts. It is ideal for structured review sessions, competency validation, and exam-focused study prior to licensure testing. Due to its strong focus on medication safety, clinical assessment accuracy, infection prevention, documentation standards, and prioritization of care, this document serves as a comprehensive fundamentals review and high-yield NCLEX-PN preparation guide.
