Which of the following is an example of a sign?

• A. Headache
• B. Fever
• C. Nausea
• D. Dizziness

Answer: (B)

In assessing a patient, a sign is an objective, observable finding, while a symptom is a subjective experience reported by the patient. Fever fits as a sign because you can verify it with a thermometer or observe an elevated body temperature—something measurable and not solely based on the patient’s description. Headache, nausea, and dizziness are symptoms; they are sensations the patient experiences and must report to you. Recognizing fever as a sign helps you identify illness and proceed with appropriate assessment and interventions, even when the patient can’t fully describe how they feel.
