CAMRT Radiography Practice Exam

What is the normal rate of respiration for an adult?

1. 8-12 breaths per minute

2. 12-20 breaths per minute

3. 20-30 breaths per minute

4. 30-40 breaths per minute

The correct answer is: 12-20 breaths per minute

The normal rate of respiration for an adult typically falls within the range of 12 to 20 breaths per minute. This range is considered healthy and reflects the average resting respiratory rate for adults in various situations—whether at rest, during light activity, or under normal conditions without stress or exertion. Factors such as age, fitness level, and overall health can influence an individual’s respiratory rate. However, the established standard serves as a guideline for healthcare professionals to assess respiratory function and identify potential abnormalities. A rate below 12 breaths per minute may indicate bradypnea (slow breathing), while a rate above 20 breaths per minute could suggest tachypnea (rapid breathing). Recognizing the normal range is crucial for monitoring patients and providing appropriate care.
