A nurse is caring for a client who is receiving total parenteral nutrition. The nurse should monitor the client for which of the following adverse effects?

A. Diarrhea is not a common adverse effect of total parenteral nutrition (TPN). TPN is administered intravenously, bypassing the gastrointestinal tract, so it does not typically cause diarrhea. B. Aspiration pneumonia is not associated with TPN, as TPN is delivered directly into the bloodstream and does not involve the respiratory system. C. Electrolyte imbalance is a significant adverse effect of TPN. TPN solutions contain various electrolytes, and improper formulation or administration can lead to imbalances, which can cause serious complications such as cardiac arrhythmias, muscle weakness, and neurological issues. D. Nausea is not commonly associated with TPN, as it bypasses the gastrointestinal tract. Nausea may occur due to other underlying conditions but is not a direct adverse effect of TPN.
