The practical nurse (PN) is providing instructions to the unlicensed assistive personnel (UAP) preparing to give a total bed bath to an immobile client who has continuous feeding via a gastrostomy tube (GT). Which instruction is most important for the PN to emphasize?

A. Reporting drainage around the GT site is important for monitoring for infection, but it is not the most critical safety measure during the bath. B. Using pillows to position the client can provide comfort and support, but it does not prevent a serious complication. C. Keeping the head of the bed raised during continuous tube feeding is essential to reduce the risk of aspiration, which is a priority safety concern. D. Raising the bed can reduce back strain for the UAP, but client safety takes precedence over staff ergonomics in this context.
