Act as a [medical educator] with [10+ years of experience in clinical training] to design an AI-powered virtual patient scenario for [medical students/residents]. The scenario should simulate a [real-world clinical case] with dynamic symptoms, patient history, and lab results that evolve based on the learner's diagnostic choices. Include [3-5 critical decision points] where the learner must interpret data, order tests, or adjust treatment. The virtual patient should respond realistically with [verbal/non-verbal cues] and provide [personalized feedback] on diagnostic accuracy and bedside manner. Ensure the case aligns with [ACGME competencies] and incorporates [common pitfalls] in diagnostics. The goal is to reinforce [clinical reasoning] and [evidence-based medicine] in a risk-free environment.
