Bridging The Gap (BTG) 40 Hour Practice Exam

What is the normal adult resting respiratory rate range (breaths per minute)?

12-20 15-25 10-18 20-30

Correct Answer:

12-20

Explanation:

Normal adult resting respiratory rate is about 12 to 20 breaths per minute. This range reflects the typical ventilatory control at rest, where the brainstem and chemoreceptors keep carbon dioxide levels stable by adjusting how often you breathe. Rates within this window indicate normal resting ventilation; rates outside it can signal underlying issues or influences like fever, anxiety, or sedation. Among the options, 12-20 matches the standard resting range, while the others either dip below or rise above what’s expected for a calm, at-rest state.
