• B. Pain in the chest.
• C. Dizziness.
• D. Shortness of breath.

Answer: (D)

Dyspnea describes a subjective sensation of breathing discomfort, i.e., the experience of shortness of breath. It’s a patient-reported symptom, not something like difficulty sleeping, chest pain, or dizziness. This feeling can vary with activity, body position, and underlying health problems, and clinicians explore it by asking when it started, what triggers it, how severe it is, and whether other signs accompany it. Dyspnea can arise from a range of causes, including respiratory conditions (like asthma or COPD), cardiac issues (such as heart failure), or anemia, and terms like dyspnea on exertion or orthopnea specify how the symptom presents.
