Which statement best contrasts irritant vs vesicant chemotherapy drugs?

• A. Irritants damage veins; vesicants cause tissue necrosis if infiltrated
• B. Irritants cause tissue necrosis; vesicants have no tissue damage
• C. Both cause identical tissue damage
• D. Neither damages tissue

Answer: (A)

The main idea here is how tissue injury differs between irritant and vesicant chemotherapy drugs. Irritants primarily affect the vein, causing inflammation or phlebitis and venous irritation, but they are not as likely to cause serious tissue damage if they stay within the vessel. Vesicants, on the other hand, have the potential to cause severe tissue injury—necrosis, blistering, and ulceration—if they leak into surrounding tissue outside the vein (extravasation or infiltration). Because of this, the statement that irritants damage veins while vesicants cause tissue necrosis if infiltrated correctly captures the key distinction. Other options are inconsistent with this difference: the idea that irritants cause tissue necrosis is not accurate, and the notion that vesicants cause no tissue damage is incorrect.
