CAMRT Radiography Practice Exam

What is the average adult respiratory rate range?

1. 8 - 16 breaths per minute

2. 10 - 18 breaths per minute

3. 12 - 20 breaths per minute

4. 15 - 25 breaths per minute

The correct answer is: 12 - 20 breaths per minute

The average adult respiratory rate range is generally accepted as 12 to 20 breaths per minute, making this the correct answer. This range reflects the normal rate at which healthy adults breathe at rest. Respiratory rates outside of this range may indicate underlying health issues or variations in individual physiology. Rates below 12 breaths per minute could suggest bradypnea, which may occur in various conditions including certain medications or respiratory issues. Conversely, rates above 20 breaths per minute may suggest tachypnea, often seen in response to exertion, anxiety, or respiratory distress. Recognizing the normal respiratory rate is important for healthcare providers in assessing a patient's respiratory status and overall well-being.
