Correct answer: C — Start prednisolone 60 mg daily immediately and arrange same-day ophthalmology assessment

This presentation strongly suggests giant cell arteritis with cranial ischaemic features: jaw claudication and a new visual symptom. Prednisolone 60 mg daily should be started immediately, before ultrasound or biopsy, because delaying treatment risks irreversible visual loss. Any new visual symptom requires same-day ophthalmology assessment; ophthalmology may escalate to intravenous methylprednisolone if ocular ischaemia or evolving visual loss is identified. Prednisolone 15 mg is a polymyalgia rheumatica dose and is inadequate for GCA. Aspirin is not a substitute for corticosteroids. Diagnostic testing must not delay treatment, and routine referral is inappropriate given the visual symptoms.
