Tachypnea is characterized by which of the following?

Tachypnea refers to an increased respiratory rate, which is correctly defined as fast breathing. This condition is often a physiological response to various factors such as anxiety, fever, exertion, or underlying health issues, including respiratory or cardiac problems. By understanding tachypnea, it becomes clear that it is distinct from the other terms listed. For instance, slow breathing would correlate with bradypnea, difficulty in breathing would describe dyspnea, and controlled breathing may refer to techniques used to manage breathing patterns rather than a specific clinical condition. Hence, the identification of tachypnea as fast breathing is essential in clinical settings for assessing a patient's respiratory status.
