Tachypnea is defined as which of the following?

• A. increased breathing rate
• B. decreased breathing rate
• C. abdominal distention
• D. abnormal heartbeat

Answer: (A)

Tachypnea reflects an increased breathing rate. It means the animal is making breaths more quickly than normal, which is a signal the body is trying to ventilate more rapidly in response to factors like fever, pain, hypoxemia, or pulmonary disease. It’s about how often breaths occur, not necessarily how deep each breath is—so tachypnea can occur with shallow or normal-depth breaths, whereas hyperpnea would emphasize increased depth as well as rate. This is different from a decreased breathing rate (bradypnea), which is a slower-than-normal rate; and it’s not related to abdominal distention or heart rhythm abnormalities, which involve other systems.
