What is the average number of breaths per minute for a resting adult?

The average number of breaths per minute for a resting adult typically falls within the range of 12 to 20 breaths. When determining the best answer, the range of 15-20 breaths is more commonly accepted as the normal respiratory rate for a resting adult. Therefore, the option indicating 15-20 breaths is more accurate as it encapsulates the typical physiological norms. A range of 10-15 might be on the lower end of normal, suggesting a potential bradypnea condition, while options of 20-25 and 5-10 are out of range for a healthy resting adult. Understanding normal respiratory rates is essential for assessing respiratory health and recognizing potential abnormalities.
