Which complication may result from the unintentional administration of vesicants?

The complication resulting from the unintentional administration of vesicants is tissue death. Vesicants are agents that can cause severe tissue damage when they extravasate, meaning they leak out of the vein into surrounding tissue. This can lead to necrosis of the affected area, resulting in permanent damage that may necessitate surgical intervention. Tissue death occurs because these agents cause a severe inflammatory response and can directly damage cellular structures, leading to cell death and compromised tissue integrity.

While swelling and redness are common symptoms associated with inflammation and irritation caused by vesicants, they do not accurately capture the severity of the potential damage, which can advance to tissue necrosis. Increased circulation and reduced pain perception are not relevant complications of vesicant administration; rather, these options do not reflect the primary risks associated with extravasation.
