Prompt
A 48-year-old patient with long-standing evening leg restlessness has been on pramipexole for 3 years. Symptoms now start mid-afternoon and involve the arms. They request a higher dose and fear any medication change will destroy sleep. Ferritin is 55 ng/mL.

Candidate instructions. Explain the diagnosis of restless legs syndrome in plain language, what augmentation means, why increasing pramipexole is unhelpful, why iron matters despite normal energy levels, outline a collaborative switch toward an α2δ ligand with iron repletion, check understanding, and safety-net. The examiner plays the patient. [2][3][4]
