What Is an Example of Subjective Observation in CNA Practice?

A subjective observation is information a resident tells you about how they feel, something you cannot measure or verify yourself. In CNA practice, it is the resident's own words, such as pain, nausea, dizziness, or anxiety. For example, if a resident says, "My stomach hurts," that is a subjective observation. If you see them grimacing and guarding their abdomen, that is objective.

Subjective vs. Objective: Key Difference

• Subjective: Reported by the resident. Example: "I feel short of breath."
• Objective: Observed or measured by you. Example: Respiratory rate 28, audible wheezing.

CNAs must document both accurately. Subjective data belongs in quotes when possible, because it reflects the resident's experience, not your interpretation.

Examples of Subjective Observations

• "I have a headache."
• "I feel like I'm going to vomit."
• "My knee is throbbing."
• "I'm scared about my surgery tomorrow."
• "I didn't sleep well last night."

Each example is subjective because only the resident can feel it. You cannot see or measure a headache, nausea, or fear.

How to Document Subjective Observations

1. Use the resident's exact words in quotation marks.
2. Record the time and what you were doing when they said it.
3. Report it to the nurse promptly, especially if it signals a change in condition.
4. Follow up with objective data, vital signs, behavior, or physical signs.

Why It Matters for the CNA Exam

Exam questions often ask you to distinguish subjective from objective findings. Remember: if the resident says it, it's subjective. If you observe or measure it, it's objective. Practice with documentation questions and answers to build confidence.
