Final answer:
A CNA should use a wet, soapy wash cloth to clean from the meatus outward on the catheter during catheter care.
Step-by-step explanation:
When a CNA is doing catheter care, a wet, soapy wash cloth should be used to clean from the meatus outward on the catheter. Proper cleaning is important to prevent infection and maintain hygiene. The meatus is the opening where the catheter is inserted, and cleaning outward helps remove any bacteria or debris.
