To begin, photocopy the three-by-three-inch hydrocolloid containment dressing along the side of the measurement lines to create a measurement template. Cut the photocopied template along the one-inch line and then the two-inch line to create a two-inch circle with a one-inch center. Use this template to cut the non-adhesive foam dressing, creating a two-inch circle with a one-inch center.
Use the same template to cut a two-inch circle in the center of the four-by-four-inch extra thin hydrocolloid dressing. Cut the hydrocolloid layer of the three-by-three-inch containment dressing at the 1 1/2-inch line. Pull back the paper liner of the hydrocolloid layer of the containment dressing to expose the adhesive.
Place the cut foam dressing within the two-inch circle of the adhesive.
