The patient can't breathe. Why?
You don't get the diagnosis. You get the patient. Interview them, examine them, order the workup, weigh the differential, and commit — then travel backward through time to discover where the disease actually began.
Free while in founding-learner access — no card, no catch. Built for nursing students and their educators.
6:40 AM. A 67-year-old man walks in slowly, pausing every few steps. He refuses to lie back on the stretcher.
“My breathing has gotten much worse since yesterday.”
Every case is a mystery. Not a quiz.
Three foundational mysteries build the core reasoning rhythm. Three advanced emergencies test time-critical recognition, prioritization, and escalation. No multiple-choice shortcuts — you interview, examine, order labs, build a differential board, and commit, the way it happens at the bedside.
The Patient Who Can't Breathe
67M — “My breathing has gotten much worse since yesterday.”
The Patient Who Won't Stop Vomiting
24M — “I can't stop throwing up.”
The Patient Who Is Getting Sicker by the Minute
78F — “She's just not herself today.”
The Patient Whose Words Stopped Working
71F — “Her words came out all wrong at breakfast.”
The Patient Who Is Vomiting Blood
58M — “I threw up blood this morning.”
The Patient Whose Lungs Sound Perfectly Clear
44F — “It hurts to breathe and I almost fainted.”
The MALDEK Method.
Six moves, always in the same order. Solve enough mysteries and the rhythm becomes how you think — at the bedside, on the NCLEX, everywhere.
Who is this patient? What brought them here? Which details of history, environment, lifestyle, medications, family, and social circumstances matter?
What should this body system normally be doing? Normal anatomy, normal physiology, the body's normal response.
Where did normal physiology first begin to fail? Which risk factor, exposure, behavior, medication issue, or social determinant began the cascade?
How did the body try to maintain homeostasis? Which compensatory mechanisms activated, why they helped at first — and how they eventually made things worse.
Why these symptoms? Which findings support the leading diagnosis, which argue against it, and which dangerous diagnosis cannot be missed?
What needs treatment now? What targets the underlying physiology? What chronic management follows — and what earlier intervention could have changed the trajectory?
Then the Time Machine runs it backward. After you commit to the diagnosis, every case rewinds along the disease's own timeline — so you see the pathophysiology as a story, not a list. Heart failure took 15 years. DKA took months. Sepsis took days. The stroke took minutes. The machine adapts to the disease.
Every module supports the reasoning.
The mysteries are the spine of MaldekChin. Everything else strengthens a specific step of how you think — same disease library, different camera angle.
Your Reasoning Fingerprint
Every case produces a Clinical Reasoning Score out of 100 and a Reasoning Fingerprint across seven domains — signal recognition, history prioritization, focused examination, diagnostic workup, differential discipline, treatment sequencing, and reassessment & prevention — not just whether you got it right. Watch the fingerprint sharpen as you solve more mysteries.

Case 001 is waiting
You do not get the diagnosis. You get the patient.
He's been waiting since 6:40 AM. His SpO₂ is 88% and falling. Reason your way there.
