Where students lose points Forgetting to convert weight-based dosing before solving for rate — the #1 error on this question type.
What it actually covers

Three subjects. The ones that decide whether you pass.

Dosage & calculations

Weight-based dosing, IV drip rates, conversions

The math itself isn’t hard. Knowing which formula the question is actually testing — that’s where points disappear.

Pharmacology

Drug classes, not just drug names

Memorizing 200 individual drugs doesn’t work. Understanding the 20 mechanisms behind them does.

Pathophysiology

Why the body does what it does

Once the mechanism clicks, the NCLEX-style question stops being a memory test and starts being logic.

The free Starter Pack covers dosage calc and pharmacology. Pathophysiology resources are next.

Who’s behind this

Built from the floor, not just the textbook.

I’m a nursing instructor with 3 years in the classroom and 10 years as a nurse, most of that in the OR. I built NurseSimVault because the gap between “what’s in the textbook” and “what actually gets asked on exams” is where most students lose points — and it’s a fixable gap.
