B Exposure to urine, bile, stool, acidic fluid, and purulent wound exudates carries a moderate risk for skin breakdown.
C Exposure to gastric and pancreatic drainage has the highest risk for skin breakdown. A patient whose skin is exposed to excessive moisture has an increased risk of skin breakdown due to changes in skin pH and maceration of skin.
D Serosanguineous drainage is not caustic to the skin, and the risk of skin breakdown from exposure to this fluid is low.
