Dosage Calculation
Move from math anxiety to medication safety confidence. Build the calculation fluency you need for med-administration exams, clinical med passes, and NCLEX-style safety questions.
Hi, I'm Dr. David Zapencki.
I've spent over twenty years in nursing education, and I built Online Nurse Training because nursing students don't need more information — they need help turning overwhelming information into clinical reasoning. In school, in clinicals, and on the NCLEX.
Built for the entire journey.
Nursing school doesn't unfold all at once — and your study tools shouldn't either. The materials in The Pathway are designed to grow with you, supporting the specific demands of each stage of your education.

The Pathway.
Each book in The Nursing School & NCLEX Preparation Pathway is paired with a quiz app and a full course on Udemy — three formats that reinforce the same learning across reading, practice, and instruction.
Pharmacology
Stop memorizing endless drug facts. Learn to recognize what's safe, unsafe, expected, and urgent — by class, action, and the nursing responsibilities that surround every medication.
Clinical Judgment
Turn nursing knowledge into safe decisions. Practice the cue recognition, prioritization, and clinical reasoning that show up in case-based exams and Next Generation NCLEX questions.
Prioritization & Delegation
Decide what matters first, who should do it, and what is safest. Build the management-of-care thinking that carries you through senior practicum, leadership courses, and management-of-care NCLEX questions.
How we think about teaching.
Nursing students aren't born knowing how to think like a nurse. They build that capacity, over time, through a specific kind of practice.
Clinical reasoning is what students do in the moment — recognizing the cues that matter, prioritizing what's most urgent, choosing safe interventions, and understanding the rationales behind their decisions.
Clinical judgment is the skill that develops from doing clinical reasoning, again and again, across the cases and complications students encounter throughout their program.
Thinking like a nurse is what emerges when those two — practice and skill — mature into professional capacity. That's the destination.
Every product in The Pathway is designed with this progression in mind. The materials don't just prepare students for tests. They build the underlying judgment students will use at the bedside, on every shift, for the rest of their careers.

The Dosage Calculation Guide
Step-by-step formulas, common pitfalls, and worked examples for the calculations nursing students see in fundamentals, skills lab, and clinicals. The fastest way to move from math anxiety to medication safety confidence.
The Pharmacology Study Guide
Drug classes organized by action and indication — mechanisms, side effects, and nursing considerations, structured for quick review and lasting recall. The starter framework that makes drug memorization stop feeling random.
The Clinical Judgment Guide
A practical introduction to the NCSBN Clinical Judgment Measurement Model, with strategies for the case-based questions used in nursing exams and the Next Generation NCLEX. Cue recognition through outcome evaluation, in plain language.
The Prioritization & Delegation Guide
Frameworks for "who do you see first" and "what can you delegate" decisions — the priority-setting logic students need across the program and on the NCLEX. Structured around the actual decision points, not abstract theory.
Plus a separate guide for nurses retaking the NCLEX, and our free newsletter for monthly study help.
