Practice Lab principle
Describe what you observe first. Then connect the observation to mechanism, troubleshooting, or next-step reasoning. Avoid jumping from one clue to a final diagnosis.
Educational scope: All cases are synthetic and simplified. They are designed for conceptual practice, not clinical decision-making or independent procedural guidance.
