Identify the word that should be corrected in the sentence: Based on the principals of asepsis, the nurse should consider a sterile packet below waist level to be contaminated.

The word that needs correction in the sentence is "principals." The correct word to use in this context is "principles." "Principles" refers to fundamental truths or propositions that serve as the foundation for a system of belief or behavior, which is appropriate when discussing the guidelines or standards of asepsis in a nursing context. "Principals," on the other hand, refers to individuals who hold a position of authority or leadership, which is not relevant to the subject of aseptic technique. Therefore, replacing "principals" with "principles" clarifies that the sentence is discussing the basic tenets of asepsis that the nurse should keep in mind regarding sterile practices.
