Observation is noticing; reporting is telling the nurse; Documentation The written record of care and observations Full entry → is writing it down. Objective data Signs the aide observes or measures Full entry → are signs the aide can see, hear, measure, or smell; Subjective data Symptoms the resident reports Full entry → are symptoms only the resident can feel and describe. The aide reports changes in condition — skin tears, Sudden confusion An abrupt change in mental status Full entry →, changes in vital signs, bleeding — promptly. Documentation must be timely, accurate, in Black ink The standard permanent ink for charting Full entry →, with No erasures The rule against erasing or using correction fluid Full entry → or correction fluid, and every entry signed. If it is not documented, it is considered not done.
Why this matters
The medical record is a legal document and the team's communication tool. Accurate, timely charting protects the resident through continuity of care and protects the aide as a legal record of care given. Poor documentation — erasures, guesses, late entries, opinions — can hide a change in condition and lead to harm. The aide's disciplined observation and honest reporting are often what catch a problem early. These notes are educational exam preparation only — state registry rules, NNAAP/Credentia/Prometric materials, facility policies, nurse delegation, care plans, skill checklists, and local scope-of-practice rules vary and must be followed.
The college version
1. Objective vs subjective data (signs vs symptoms)
Objective data, or signs, are what the aide observes or measures: temperature, pulse, skin color, swelling, a Skin tear A break in the skin Full entry →, or the amount of urine. Subjective data, or symptoms, are what the resident reports: pain, nausea, dizziness, or sadness. Both are valuable. The aide records objective observations and quotes the resident's exact words for subjective symptoms, using quotation marks.
2. Reporting changes in condition
The aide reports promptly any change: a new skin tear or bruise, sudden confusion or a change in mental status, a vital-sign change (fever, rapid pulse, low blood pressure), bleeding, a fall, new pain, or changes in eating, urinating, breathing, mood, or behavior. When in doubt, report it — early reporting stops small problems from becoming emergencies. The aide reports facts to the nurse and never decides for the resident that a change is unimportant.
3. Documentation principles
Documentation must be timely (as soon as possible after care), accurate (exact facts and numbers), and legible. Use black ink because it is permanent and copies clearly. Use no erasures, no correction fluid, and leave no blank lines. If an error is made, draw a single line through it, write "error," initial it, and date it — never erase or scribble. Sign An observable finding (redness, swelling, fever) Full entry → every entry with name and title (and date/time). Never chart for another person, and never chart care in advance. Remember: "if it wasn't documented, it wasn't done."
How it works
- Observe the resident during every interaction.
- Separate what you saw or measured (objective) from what the resident said (subjective).
- Document promptly, accurately, in black ink, signed and dated.
- Report any change or abnormal finding to the nurse.
- Follow up to ensure the nurse has received and acted on the report.
Common confusions
| Do not confuse | With | Difference |
|---|---|---|
| Sign | Symptom | A sign is observed or measured (fever); a symptom is reported (pain) |
| Objective | Subjective | Objective is factual and measurable; subjective is the resident's report |
| Reporting | Documentation | Reporting is telling the nurse; documentation is the written record — do both |
| Correcting an error | Erasing | Draw one line, write "error," initial; never erase or use correction fluid |
| "Not charted" | "Done but not written" | Legally, undocumented care is considered not done |
Memory aids
Remember "F-A-C-T-S" for good charting: Facts only (not opinions), Accurate, Complete, Timely, Signed. And remember the flow: Observe → Report → Document.
Quick review
Topic Recap
The aide observes, reports, and documents. Objective data (signs) are what the aide sees or measures; subjective data (symptoms) are what the resident reports. Changes such as skin tears, sudden confusion, vital-sign changes, and bleeding are reported immediately. Documentation is timely, accurate, in black ink, free of erasures, and signed — because if it is not documented, it is not considered done. Accurate records and prompt reports turn observation into safe action.
Knowledge Check
- Distinguish objective data from subjective data, giving one example of each.
- Name two changes in condition that require immediate reporting.
- What ink color is used for charting, and why?
- How is a charting error corrected?
- Why does the record say "if it wasn't documented, it wasn't done"?
Answers and Rationales
- Objective data (signs) are seen or measured — for example, a skin tear or a temperature of 101°F; subjective data (symptoms) are reported by the resident — for example, "I feel dizzy."
- Any two of: a skin tear, sudden confusion, a vital-sign change, bleeding, a fall, or new pain — all reported to the nurse immediately.
- Black ink, because it is permanent and copies clearly; no pencil, no erasures, no correction fluid.
- Draw a single line through the error, write "error," and initial and date it — never erase, scribble, or use correction fluid.
- The medical record is a legal document; if care is not recorded, it is treated as if it was not performed.
Eli explains
The same idea, in plain words
Explain it like I’m 10
Think of the aide as the resident's "camera and notepad." The camera records only what is actually there (objective), and the notepad captures what the resident says (subjective). Together they build the story the nurse needs to make decisions. This comparison stops being exact because a camera does not interpret, but a careless writer can blur the line between what was seen and what was assumed — so the rule is "record facts, not opinions," and report anything unusual even if you are unsure it is important.
Simple Example
The aide sees a red, open area on a resident's heel (an objective sign) and the resident says it hurts (a subjective symptom). The aide writes both — "2-cm reddened open area on right heel; resident states 'it hurts'" — and then reports it to the nurse. The aide does not write "bedsore" (a diagnosis) or "not my problem."
Worked example
- Observe the resident during every interaction, noting anything new or different.
- Separate what you saw or measured (objective) from what the resident said (subjective).
- Document promptly, accurately, in black ink, signed and dated — quoting the resident's words for symptoms.
- Report any change or abnormal finding to the nurse, especially skin tears, sudden confusion, vital-sign changes, and bleeding.
- Get help immediately for acute changes — bleeding, sudden confusion, a fall, new pain, or a vital-sign change — and follow up to confirm the nurse received and acted on your report.
Key takeaways
- High yield: Objective = signs (seen or measured); subjective = symptoms (the resident reports).
- High yield: Report sudden confusion and changes in vital signs immediately — they can signal serious problems.
- High yield: Chart in black ink, with no erasures and no correction fluid, and sign every entry.
- High yield: "If it wasn't documented, it wasn't done."
- Report skin tears and any bleeding promptly.
- Record the resident's exact words in quotation marks for symptoms.
- To correct an error, draw a single line through it, write "error," and initial and date it — never scribble.
- Report anything unusual even when unsure; the nurse decides how important it is.
