Empty at one-third to one-half full
The colostomy pouch is emptied when it is one-third to one-half full. Emptying at this level keeps the weight of stool and gas from pulling the skin barrier away from the skin. A heavy pouch drags on the adhesive seal, breaks it, and allows stool to leak onto the peristomal skin, causing irritation and skin breakdown. Emptying early also reduces bulging under clothing, odor when the pouch is opened, and the embarrassment that discourages clients from going out.
Emptying versus changing
Clients often confuse emptying the pouch with changing the appliance. Emptying, through the drainable outlet, happens several times a day depending on output. Changing the skin barrier (wafer) and pouch happens much less often, typically every 3–7 days, or sooner if it leaks or the skin under it itches or burns. Teaching both separately prevents a client from waiting for a barrier change to empty a full pouch.
| Teaching point | Correct practice |
|---|
| When to empty | At one-third to one-half full |
| When to change the barrier | Every 3–7 days, or if leaking or itching |
| Fixed time schedule | Not used; depends on how full the pouch is |
| Waiting until full | Avoided; weight breaks the seal and causes leaks |
Why the other options are wrong
Emptying every 2 hours regardless of contents is unnecessary and ignores how much output there actually is. Emptying only at each barrier change means the pouch would become heavy and leak between changes. Waiting until the pouch is completely full and heavy is the exact situation the teaching aims to prevent. Watch out! Answers that set a fixed clock time sound organized, but stoma output varies, and the pouch is emptied by fullness.
Exam takeaway
Discharge teaching for a new colostomy covers emptying, barrier changes, skin care, diet, odor control, and when to call for help, such as a change in stoma color, persistent leakage, or skin breakdown. Key point! Empty the pouch when it is one-third to one-half full; change the barrier every 3 to 7 days.
