One of the following is the subjective data:

Appeared in: IGNOU PB Bsc Nsg.Entrance-2026

Explanation

Subjective data, also known as symptoms, is information provided from the patient's perspective.
It includes feelings, perceptions, and concerns that cannot be directly measured or verified by a healthcare provider.
A patient's description of pain is a classic example of subjective data, as pain is a personal and individual experience that only the affected person can report.

Option A: Vital signs (temperature, blood pressure, heart rate, respiratory rate) are measurable and observable facts, which classifies them as objective data.
Option B: Laboratory test results provide quantifiable, measurable values about a patient's physiological state, making them objective data.
Option D: An ECG provides a graphical, measurable record of the heart's electrical activity, which is a form of objective data.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Differentiating between subjective and objective data in nursing assessment as background academic context rather than a clinical decision trigger.
Distinguishing between subjective and objective data is a fundamental skill in the assessment phase of the nursing process (ADPIE).
Accurate data collection and categorization ensure that nursing diagnoses are correct and that the care plan effectively addresses the patient's actual and potential health problems.
What if the patient is unable to communicate verbally (e.g., is intubated, an infant, or has cognitive impairment)? The nurse must then rely on objective signs (e.g., grimacing, guarding, increased heart rate) and use validated non-verbal pain assessment tools (like the FLACC or CPOT scales) to infer the subjective experience of pain.

How to Approach the Question

First, define the key term in the question: 'subjective data'. Recall that this is information reported by the patient that cannot be directly measured by an observer.
Next, analyze each option to determine if it is something the patient feels or reports, versus something a healthcare provider can measure or observe.
Evaluate Option A: Vital signs are measured. This is objective.
Evaluate Option B: Lab results are measured. This is objective.
Evaluate Option C: A patient's description of pain is reported by the patient. This is subjective.
Evaluate Option D: An ECG is a measured tracing. This is objective.
