A nurse is performing a comprehensive assessment on a patient. Which finding would the nurse identify as subjective data?

Subjective data refers to information that is reported by the patient and cannot be directly observed or measured by the nurse. A patient's report of dizziness is something only the patient can describe — it is a symptom perceived internally and communicated verbally, making it classic subjective data. Blood pressure reading is objective data because it is measured directly using a sphygmomanometer and produces a quantifiable, observable value. Skin temperature is also objective data because the nurse can directly assess it by touch or with a thermometer. Respiratory rate is objective data because the nurse counts breaths per minute through direct observation. The distinction between subjective and objective data is foundational to the nursing assessment process. Subjective data forms the 'S' in SOAP charting and includes symptoms, feelings, perceptions, and self-reported history. Objective data forms the 'O' and includes signs that are measurable or observable by a healthcare provider. Recognizing this distinction helps nurses accurately document findings, formulate nursing diagnoses, and communicate effectively with the interprofessional team. When a patient says 'I feel dizzy,' that statement can only be validated through the patient's own experience, cementing it as subjective data and the correct answer here.
