What is the role of the hydrocolloid portion of the skin wafer?

• A. Odor control
• B. Color enhancement
• C. Absorption
• D. Thermal insulation

Answer: (C)

Absorbing drainage is the role of the hydrocolloid portion. This hydrophilic material sits at the inner layer of the skin wafer and draws moisture away from the stoma output. As it absorbs, it swells and forms a gel, which helps keep the peristomal skin dry and protected, and aids in maintaining a secure seal between the wafer and the skin. This moisture-absorbing action reduces skin irritation and helps prevent leakage around the stoma.

Odor control, color, and thermal insulation aren’t functions of the hydrocolloid layer. Odor management is typically handled by the pouch system or deodorizing options; color and appearance aren’t affected by this hydrocolloid component; and insulation isn’t a goal of the hydrocolloid in standard ostomy wafers.
