Which term describes a normal breathing pattern?

• A. Dyspnea
• B. Eupnea
• C. Crackles
• D. Ronchi

Answer: (B)

Eupnea describes a normal breathing pattern: regular rhythm and rate at rest, effortless depth, no use of accessory muscles, and symmetrical chest movement. In adults, this is typically about 12 to 20 breaths per minute with quiet, unlabored breaths. Dyspnea means shortness of breath or difficult breathing, which shows breathing isn’t normal. Crackles and rhonchi are abnormal breath sounds heard on auscultation—crackles suggest fluid in the airways or alveoli, while rhonchi indicate secretions or obstruction in larger airways. Because eupnea reflects a normal, effortless pattern, it is the correct term to describe normal breathing.
