Filed under: things I wish someone had handed me on placement
Placement is where nursing school gets real.
I'm Dayo — an ICU nurse and preceptor in Toronto. I build the practice tools I wish my students had: short reps, real rhythm strips, honest feedback — the kind of thing you can run on a break, coffee going cold beside you. The ECG trainers are live. More modules are coming, one at a time.

DayoRN is growing into the set of drills I actually want in my students' pockets. The ECG, Respiratory and Advanced modules below are finished and ready to use right now. The rest are on my workbench — listed honestly below, no fake buttons. Here for an exam? Start with the first tile below →

NCLEX Trainer
The question bank I wish someone had handed me: 2,663 questions, every one read and checked. Canadian the whole way through — SI units, CNO and PHIPA, generic drug names.
It asks the way the exam asks: 40 unfolding case studies, bowtie and trend questions, SATA with partial credit — 634 next-gen items — and a rationale with an Educational Objective on every question.
What's in the bank
Tap a section to jump straight into it in the NCLEX Trainer.
Tutor mode teaches as you go. Exam mode is the full rehearsal — 70 questions, 3 hours. CAT tests adapt to every answer, 85–150 questions, with a pass/fail estimate. The diagnostic report shows exactly where you're weak, with a drill button beside each spot.
The loop: learn in Tutor mode, rehearse in Exam or CAT mode, then live in My Misses until they stop being misses. Sign in and it all follows you between devices.
The gentler on-ramp: study each rhythm first, then get quizzed on it.

Learn mode — study first, quiz second

Which one should I use? This one, if ECGs are new to you or you want a short daily drill. Ten honest minutes beats an hour of flashcards. ← my students start here
The deep end: 24 rhythms on Lead II strips, then full 12- and 15-lead ECGs and axis deviation. Calipers throughout — you measure it yourself.
LEAD II · 25 MM/SHR · PR · QRS · QT
24 rhythms across six groups, similar-looking options
12 & 15-lead ECGs in Part 2 — V4R, V8, V9 included
Axis deviation in Part 3, the quadrant method
Draggable calipers — intervals in ms, boxes, bpm
Which one should I use? This one, if rhythms are starting to make sense and you want the full picture — or 12-leads and axis still feel shaky. The calipers are draggable. The excuses are not. — D
The ventilator, minus the fear — every mode and setting, taught on a fake vent that shows real numbers.
Every mode — VC, PC, PS, SIMV, CPAP, BiPAP, side by side
The fake vent — answer from what its screen shows
Read → understand → apply — chains that end with what to do about it
Alarm drills — the alarm fires, you call it
Which one should I use? This one, before a vented patient is yours — and ABG beside it; same conversation. The vent isn’t scary. The 3 a.m. alarm is. — D
A full CNPLE question bank for NP students — 2,663 questions in the NCLEX Trainer's format, exam mode built to the real Ontario exam: 185 questions, 4 hours.
2,663 questions, every one with a textbook source
Tutor + CNPLE Exam modes — rationales, then the real format under the clock
215 case studies — the way the CNPLE actually asks
Ontario law & CNO standards built in — PHIPA, controlled acts, NP prescribing
Which one should I use? This one, if you're an NP student aiming at the CNPLE — or an RN stretching into primary-care thinking. 2,663 questions. My laptop fan has seen things. — D
ACLS as megacode drills — a rhythm strip, a monitor, and a chain of decisions where each answer sets up the next.
21 megacode chains — rhythm, first action, drug and dose, next step
Arrest, bradycardia + tachycardia algorithms
Drug & dose table — epinephrine, amiodarone, adenosine, atropine
H's and T's — the reversible causes, and the fix for each
Which one should I use? This one, before an ACLS course, a recert, or a shift where the crash cart might roll. Megacodes: the group project where everyone’s watching. — D
Nothing here is made up. Every question in the banks traces back to one of these — real textbooks, peer-reviewed, free to read and openly licensed. When a rationale feels thin, this is where it came from: go read the chapter.

Nursing Fundamentals, 2e
The fundamentals backbone — safety, infection control, vitals and medication basics behind the Fundamentals and Nursing Sciences banks.
The regulator's own documents — Code of Conduct, Scope of Practice, Medication, Documentation, Confidentiality and Privacy — behind the Ontario standards questions.
Some topics land better out loud, on a whiteboard, at 1.5× speed the night before. These are the channels I point my own students to — nursing-first teaching and proper pathophysiology, all free.

NCLEX review lectures and hands-on skills demos from Nurse Sarah — the nursing-school staple.
Lab values that actually matter on the floorIn the works
Electrolytes, kidneys, CBC — the ones you'll actually get paged about, not all forty on the printout.
Med mathIn the works
Dosage calculations and drip rates, checked the way a preceptor checks them — slowly, twice.
ISBAR handoversIn the works
Structure a handover that doesn't ramble, so the next nurse gets the story in ninety seconds.
Head-to-toe assessmentIn the works
A checklist drill in the order you'd actually do it at the bedside, not the order in the textbook.
Spotting deteriorationIn the works
Sepsis and the quietly-crashing patient — the one who looks "fine" until they very much aren't.
ICU basicsIn the works
Vents, lines, and drips without the panic. What the numbers mean, what to touch, what to never touch.
“What do you do first?”In the works
Short clinical scenarios, one decision at a time — because that's how the floor actually asks the question.
One module at a time. I have a day job. — D

How it works
How a module works
Every module here follows the same three rules. If a future one doesn't, it doesn't ship.
1.
Short rounds you can finish on a break
No hour-long sessions, no setup. Open it, run a round, close it. If it can't survive a fifteen-minute break and a cold coffee, it's too long.
2.
Feedback that tells you why
Not just right or wrong — the clues that mattered, and why the similar-looking answer wasn't it. A red X teaches you nothing. A reason does.
3.
Built from real placement situations
The scenarios come from things students actually get tripped up by on the floor — not exam-bank trivia. And it's education only: practice here, clinical judgment out there.
About
Hi, I'm Dayo.
I'm an ICU nurse in Toronto and I precept nursing students on placement — which mostly means watching smart people freeze the first time a monitor does something interesting. It isn't a knowledge problem. It's a reps problem.
So I started building the reps. These tools are mine — designed, written and argued with between shifts, tested on my own students before they land here. I'm also working through a master's on the side (MN–Primary Health Care NP at TMU), so yes, I know exactly how little spare time you have. That's why everything here is short.
Bookmark dayorn.ca and check back. The toolkit grows one finished module at a time — never announced before it's real.
You're at DayoRN.ca — the home of all of it
This page is the front door, and dayorn.ca is the one short address worth sharing with a classmate. Skipping the hub is fine too: nclex.dayorn.ca goes straight to the NCLEX Trainer, ecgharder.dayorn.ca straight to the Rhythm Trainer and ecgsimple.dayorn.ca straight to the Rhythm Lab. One honest note — the address is brand new, so it may take a little while to start responding everywhere while DNS finishes propagating. The links above always work in the meantime.
