Which term describes rapid breathing in adults?

• A. Tachypnea
• B. Bradypnea
• C. Apnea
• D. Hyperpnea

Answer: (A)

Rapid breathing in adults is tachypnea. It means the respiratory rate is elevated at rest—typically considered above about 20 breaths per minute in a resting adult. This term focuses on how fast you’re breathing rather than how deep each breath is. Other terms describe different patterns: bradypnea is slower than normal breathing, apnea is a temporary stop in breathing, and hyperpnea refers to increased depth and rate of breathing often in response to higher metabolic demand. Tachypnea helps signal that the body is trying to compensate for conditions like fever, anxiety, hypoxemia, or metabolic acidosis.
