When teaching ostomy care, which step is essential for skin protection?

Applying stoma paste is essential for skin protection in ostomy care because it acts as a barrier between the skin and the stoma output, which can be caustic and lead to skin irritation or breakdown. The paste helps to create a secure seal around the stoma, preventing leakage and protecting the surrounding skin from moisture and harmful substances. Maintaining the integrity of the skin is crucial for preventing complications, such as infections or skin irritation, which can arise from prolonged exposure to the stoma output.

In contrast, using hot water for cleansing may not be appropriate since it can cause irritation or damage to the sensitive skin around the stoma. Positioning the pouch incorrectly can lead to leakage and does not allow for adequate protection of the skin. Measuring pouch size inaccurately can result in inadequate coverage and may leave parts of the skin exposed to output, increasing the risk of skin complications. Thus, applying stoma paste is a fundamental step in ensuring skin protection in ostomy care.
