Assess clinicians' ability to evaluate and prioritize evidence-based exercise prescriptions and safety modifications for adults with coexisting cardiovascular disease, type 2 diabetes, and chronic kidney disease. Scope includes risk stratification, FITT-based prescription (modality, intensity, frequency, progression), medication- and comorbidity-driven adjustments (e.g., beta‑blockers, autonomic neuropathy, anemia), dialysis and fluid/electrolyte considerations, glycemic management around exercise, monitoring parameters and red flags (BP, HR/RPE, glucose), and criteria for modification or referral; items require applied judgement in clinical case scenarios and justification of prioritized interventions.
