What respiratory rate is considered 'Tachypneic' for adults?

The definition of tachypnea in adults is characterized by an increased respiratory rate, typically defined as a rate greater than 20 breaths per minute. This elevated rate is often indicative of underlying conditions such as anxiety, respiratory distress, or other pathology that affects breathing.

In this context, the choice stating "equal to or less than 28 breaths/min" can be misleading, as tachypnea is specifically recognized when the respiratory rate exceeds 20 breaths/min. While a rate up to 28 breaths/min could indeed indicate tachypnea, it does not encompass the full range of what is generally considered tachypnic.

The key point is that any respiratory rate above 20 is already classified as tachypnic, so a more precise threshold that captures the essence of the term tachypnea would actually be greater than or equal to 20 breaths/min. This means that stating a cutoff at or less than 28 does not accurately reflect the term and may dismiss patients who are, in fact, tachypneic but may fall into a slightly higher range of respiratory rates.

In summary, tachypnea is recognized as an abnormally fast respiratory rate, starting from greater than 20 breaths per minute. Therefore, an alternative choice affirming a
