Core concepts
Concept 1
The nurse aide observes and reports facts, changes, and measurements rather than diagnosing.
Exam cue: Report facts and measurements, not assumptions.
Concept 2
Documentation should be accurate, timely, objective, and within facility policy.
Exam cue: Chart only care actually given and observations actually made.
Concept 3
Changes in condition, injuries, pain, refusal, confusion, skin problems, and abnormal measurements require prompt reporting.
Exam cue: Escalate new, abnormal, or worsening findings immediately.

Memory anchors
Objective Data
Objective data are facts that can be measured or observed.
Subjective Report
Subjective information is what the client says or feels.
Timely Reporting
Important changes are reported promptly, not saved for end of shift.
Accurate Charting
Chart only care provided and observations made.
No Diagnosis
The nurse aide reports observations but does not diagnose.
Intake Output
Intake and output must use the correct units and facility method.
Incident Report
Falls, injuries, or unusual events follow facility reporting procedures.
Change In Condition
New confusion, weakness, pain, fever, skin change, or breathing trouble is reported.
Refusal Of Care
A client's refusal is respected and reported to the nurse.
