During а shift hаndоff, а nurse is оrganizing care fоr multiple clients and explains the rationale used to establish priorities. The nurse preceptor listens to the nurse's statements regarding prioritization frameworks, including urgency, stability, and interpretation of clinical data. Which statement by the nurse requires correction by the nurse preceptor?
