Workup: one patient, four stations

This workup follows one morning draw from a man found on the floor at home. The morning QC hides a calibration fault, his CK is above the measuring range and needs a dilution, the smear from his CBC needs a differential, and his corrected potassium needs a call with a read-back.

It is the longest case on the path, and it uses what you practiced in Parts 1 to 4. Take it in one sitting if you can. The debrief lists each decision and links to the lesson behind it.
