In tube feeding syndrome, what adjustment may be necessary if the ability to excrete byproducts is compromised?

• A. Increase protein load
• B. Maintain current protein
• C. Decrease protein load
• D. Eliminate protein entirely

Answer: (C)

When the body’s ability to excrete nitrogenous byproducts from protein metabolism is limited, the goal is to reduce the production of those waste products. Protein in the tube feeding provides amino acids that become nitrogenous waste (such as ammonia and urea) that must be cleared by the kidneys and liver. If excretion is compromised, accumulating these byproducts can lead to toxicity and metabolic imbalances. Decreasing the protein load lowers the amount of nitrogenous waste that needs to be processed, helping prevent buildup while still meeting essential nutritional needs. Maintaining current protein or increasing it would raise the excretion burden, and eliminating protein entirely would deprive the patient of essential amino acids.
