2024 PN NCLEX Questions Nursing Practice Question
Which of the following foods is a complete protein?
Correct Answer: B
Rationale: Complete proteins contain all nine essential amino acids necessary for human health. Eggs are considered a complete protein as they provide all these amino acids in sufficient quantities, making them an excellent choice for muscle repair and overall nutrition.
In contrast, corn lacks certain essential amino acids, particularly lysine and tryptophan, making it an incomplete protein. Peanuts, while a good source of protein, are also deficient in methionine, another essential amino acid. Similarly, sunflower seeds do not provide all essential amino acids, particularly lysine. Thus, among the options, eggs stand out as the only complete protein source.
