Final answer:
The best time to shower a resident with an ostomy is likely in the early morning or before meals, ensuring that the pouch is secure and changing the pouching system after the shower on clean, dry skin.
Step-by-step explanation:
The best time to shower a resident with an ostomy would typically be when the fecal pouch is less likely to be active, which is often after a longer period of not eating, such as early in the morning or before meals. Ensuring that the ostomy appliance is secure and checking for leaks before assisting with the shower can also facilitate a smoother process. Additionally, it may be beneficial to change the pouching system shortly after the shower when the skin is clean and dry to maintain good adhesion and prevent skin irritation.
