Built a study app that has to cite every answer, and it caught a thing nursing school is oversimplifying
I'm a nursing student and I got tired of ChatGPT confidently telling me wrong things
during pharm review. So I built NurseMind: Nursing Companion — an AI tuned for
nursing/NCLEX that refuses to answer without a citation.
First real test: I asked it "why do we hold metformin before contrast." I expected
the textbook line ("contrast damages kidneys, metformin makes it worse"). Instead
it pulled from the ACR Manual on Contrast Media and gave me this:
- Iodinated contrast can cause AKI
- Metformin is renally cleared — if the kidneys take a hit, metformin accumulates
- Accumulated metformin → lactic acidosis (MALA)
- THAT'S the actual danger. Not metformin damaging kidneys.
- Current ACR guidance: only hold for 48h post-contrast if eGFR <30 or AKI is present.
Normal renal function = you don't actually need to hold it.
That contradicts what Saunders says and what came up in my lecture. Made me realize
how much of nursing school is the conclusion without the mechanism — and that
asking an AI without source-checking is honestly worse than not asking at all.
If you're prepping for NCLEX, NurseMind is free to try: [App Store link]. I'm looking
for testers who'll be brutally honest about where it bombs — what topics it whiffs
on, where citations feel weak. Educational only, sits alongside UWorld/Saunders, not
a replacement.
What other "rules" have you discovered are oversimplified once you dug into the source?
