A nurse is caring for a client who is receiving enteral feedings through a nasogastric tube and has developed diarrhea. Which of the following actions should the nurse take?

Diarrhea is a common complication of enteral feedings. When a client receiving tube feedings develops diarrhea, one evidence-based intervention is switching to a fiber-containing enteral formula, because fiber adds bulk to stool, slows intestinal transit time, and helps normalize bowel function. Adding water during tube flushes would not address the cause of the diarrhea and could dilute the feeding without therapeutic benefit for diarrhea. Slowing the instillation flow rate may be appropriate for nausea or aspiration risk but is not the primary intervention specifically indicated for diarrhea from enteral feedings. Adding yogurt to enteral feedings is not a standard evidence-based nursing intervention; probiotics may be considered, but this is a provider-driven decision and yogurt is not typically added directly to tube feeding formulas. The most appropriate independent nursing action that addresses the underlying mechanism of diarrhea in this context is changing to a fiber-enriched formula, which directly targets the hyperosmolar or rapid transit nature of the problem. This also aligns with current clinical practice guidelines for managing enteral-feeding-associated diarrhea.
