Which statement best defines a sign in clinical assessment?

• A. Sign is observed by patient.
• B. Sign is observed by clinician.
• C. Sign is measured by patient.
• D. Sign is the same as a symptom.

Answer: (B)

In clinical assessment, a sign is an objective indication that a clinician can observe or measure during examination or testing. This contrasts with symptoms, which are subjective experiences reported by the patient. Signs come from what the clinician sees or detects directly—such as a fever, rash, swelling, abnormal heart sounds, or high blood pressure measured with a cuff. An example helps: fever is a sign because the clinician can verify it with a thermometer; pain is a symptom because the patient describes it. That’s why observing a sign is something the clinician does, not something the patient reports. It isn’t measured by the patient, and it isn’t the same as a symptom.
