Correct answer: B — Refer for prompt antiviral treatment because he is within the usual treatment window

Herpes zoster antivirals are most beneficial when started early, commonly within 72 hours of rash onset, especially in older adults. The patient should be referred promptly for assessment and treatment. Pain control and advice about transmission may also be needed. Topical steroid or antibiotic treatment is not the key management step.
