Which term means 'an indication of a problem'?

• A. respiration
• B. restrict
• C. serene
• D. symptom

Answer: (D)

In health terms, the idea here is a symptom, which is what a patient experiences and reports as evidence of a problem. A symptom is subjective—something the person feels or says they are experiencing, like pain or dizziness. That makes it the fitting term for “an indication of a problem.” Other words don’t capture that sense: respiration is the act of breathing, not an indication of a problem; restrict means to limit; serene describes a calm state. So symptom is the best choice because it specifically refers to a reported sign that something isn’t right.
