Final answer:
The first step of management for a dry raised ulcer with feathery margins and satellite lesions is 3) surgical debridement followed by biopsy for further analysis.
Step-by-step explanation:
The first step of management for a dry raised ulcer with feathery margins and satellite lesions would be surgical debridement. Surgical debridement involves the removal of dead and infected tissue from the ulcer. This helps promote healing, reduces the risk of infection, and allows for proper assessment of the ulcer. After surgical debridement, a sample of the tissue can be sent for biopsy to determine the underlying cause of the ulcer.
