Which statement about essential versus nonessential amino acids in AKI PN is most accurate?

Which statement about essential versus nonessential amino acids in AKI PN is most accurate?

• A. Formulations with only essential amino acids are not recommended.
• B. Formulations with only nonessential amino acids are preferred.
• C. Nonessential amino acids should never be included.
• D. Essential amino acids alone are superior.

Answer: (A)

A balanced amino acid profile is needed in PN for AKI because the body requires both essential amino acids (which must be supplied) and nonessential amino acids (which serve as building blocks for proteins and support many metabolic processes). In illness and kidney injury, the body's ability to synthesize nonessential amino acids can be impaired, making them conditionally essential. Supplying only essential amino acids misses important substrates for tissue repair, immune function, and antioxidant needs, and can limit protein synthesis and recovery. That’s why formulations with only essential amino acids are not recommended. Including nonessential amino acids helps ensure a complete pool for proper metabolism, while still meeting the indispensable need for essential amino acids.
