Hyperkalemia: Step-by-Step Approach (Flowchart)
The USMLE Adviser Hyperkalemia flowchart turns this presentation into a short series of yes/no decisions, the way Step 2 CK and Step 3 vignettes test it. Here is how it begins.
How the flowchart starts
The flowchart starts by measuring serum K⁺ and sorting the result into three ranges: 5.0–5.5 mEq/L, above 5.5 (up to 6.5), and above 6.5 or any ECG changes. The highest range goes straight to an emergency-treatment pathway, which the full chart lays out step by step.
