Protocol Application and Deviation

1. A Protocol Is Written for the Typical Patient

A protocol is a decision tree. It's pre-authorized. Someone wrote it ahead of time so you don't have to call medical control for every routine chest pain patient.

But it's built for one patient. The typical one. Typical age. No complicating history. The classic presentation of whatever condition it covers.

Real patients don't read the protocol. So they show up outside its assumptions constantly. A chest pain protocol assumes no contraindication to its own medications. A pediatric protocol's doses and vital sign norms don't transfer to an adult. Comorbidities — renal failure, pregnancy, two complaints at once — can change which parts of a protocol still apply.

So applying a protocol well is not matching a keyword in the chief complaint to a protocol title. It's checking this specific patient against what the protocol assumed about its patient. Those are two different skills. The exam tests the second one.
