Final answer:
Venous ulcers are shallow wounds with irregular edges, often found on the legs due to poor circulation. They differ from other lesions like melanomas which present differently with a raised, uneven border.
Step-by-step explanation:
What does a venous ulcer look like? Among the provided options, venous ulcers are most accurately described as b) Shallow, crater-like wound with irregular edges. These ulcers typically occur on the legs and are caused by poor blood circulation, appearing as crater-like indentations in the skin. The edges of these ulcers are not well-defined and are often irregular. They can have a weeping, raw appearance and are prone to infection, which can result in suppuration (pus) and a delayed healing process. Unlike other skin lesions such as melanomas, which exhibit large brown or black patches with uneven borders and a raised surface, venous ulcers do not have raised, firm edges with a smooth appearance.
