What is the normal range for resting respirations in an adult?

• A. Hyperventilation
• B. 14-22 breaths per minute
• C. 12-20 breaths per minute
• D. 8-12 breaths per minute

Answer: (C)

Normal resting respirations in an adult fall into about 12 to 20 breaths per minute. This range represents breathing at rest with a normal depth and pattern, ensuring adequate gas exchange without extra effort. To determine this, count the breaths for a full minute and compare to the 12–20 range; rates higher than 20 are considered tachypnea, while rates below 12 are bradypnea. The option described as a pattern of rapid breathing is hyperventilation, which isn’t a numeric resting rate. The other numeric options either push the lower limit too low or the upper limit too high for typical resting conditions.
