Which symptom describes trouble breathing and is commonly rated on a numeric scale?

• A. Talk test
• B. 0-10 RPE scale
• C. Dyspnea
• D. Borg scale

Answer: (C)

Dyspnea is the medical term for shortness of breath, a symptom that people experience as difficulty breathing. It’s commonly quantified with a numeric rating to gauge how severe the breathlessness is, which helps instructors adjust activity or monitor safety. For example, a structured dyspnea scale assigns numbers to reflect intensity, making it easy to track changes over time or in response to effort.

Talk test describes whether you can speak in full sentences rather than giving a numeric value, so it’s qualitative rather than a numeric rating. A 0-10 RPE scale measures overall perceived exertion, not specifically the breathlessness symptom. The Borg scale refers to a numeric scale used to rate exertion or breathlessness, but when naming the symptom itself, dyspnea is the precise term.
