What is the normal range for respiratory rate in adults?

1. 10 to 15 breaths per minute

2. 12 to 20 breaths per minute

3. 20 to 25 breaths per minute

4. 25 to 30 breaths per minute

The correct answer is: 12 to 20 breaths per minute

The normal range for respiratory rate in adults is between 12 to 20 breaths per minute. This range reflects the typical breathing patterns of a healthy adult at rest. Respiratory rate can vary based on several factors such as activity level, health status, and emotional state, but in a stable condition, the 12 to 20 breaths per minute range is generally accepted as normal. The measurement of respiratory rate is an essential part of assessing a person's overall health and can indicate various medical conditions if it falls outside this range. A rate below 12 breaths per minute may suggest bradypnea, while a rate above 20 breaths per minute may suggest tachypnea, both of which can signify underlying health issues that might require further investigation. Understanding this normal range is vital for anyone involved in patient care, as it serves as a benchmark for recognizing respiratory distress or other complications.
