What is a correct statement about signs?

• A. Signs are observable manifestations of a condition
• B. Signs are subjective experiences reported by the patient
• C. Signs are measured only with instruments
• D. Signs are not related to the casualty's condition

Answer: (A)

Signs are objective, observable indicators of a condition that a clinician can detect by looking, listening, touching, or measuring. They are things others can verify, such as fever, rash, swelling, an abnormal pulse, or a lab result. This distinguishes signs from symptoms, which are subjective experiences reported by the patient, like pain or dizziness. So the statement that signs are observable manifestations of a condition captures the core idea: signs are evidence clinicians can observe or measure, not just what the patient feels or reports. The other ideas are less accurate: signs aren’t merely experiences reported by the patient, nor are they limited to measurements with instruments—many signs can be seen or felt without special tools—and signs are directly related to the casualty’s condition.
