The idea behind the cue
Subjective data are what the patient reports: symptoms, feelings, beliefs, and history. Objective data are what the nurse observes or measures: appearance, behaviors, vital signs, and test results. Keeping them separate helps the nurse assess accurately before interpreting.

Acronym
SO — Sleepy Owls.
Story
The patient says, “I feel dizzy,” while the nurse notes pale skin and a fast pulse. The spoken feeling goes in one pile; the observed signs go in the other. Mixing them blurs the assessment.
