What respiratory rate can indicate a potential problem in adults?

• A. 10-20 breaths per minute
• B. 12-16 breaths per minute
• C. Over 20 breaths per minute
• D. Under 12 breaths per minute

Answer: (C)

A respiratory rate over 20 breaths per minute can indicate a potential problem in adults because it is classified as tachypnea, which signifies that the body may be experiencing respiratory distress or other underlying health issues. This elevated breathing rate can occur in various conditions, such as anxiety, pulmonary embolism, pneumonia, or other respiratory disorders, as the body attempts to maintain adequate oxygen levels or compensate for decreased respiratory efficiency.

Monitoring respiratory rates is a crucial part of assessing a patient’s vital signs, and identifying tachypnea allows healthcare professionals to investigate further and determine appropriate interventions. The normal range for respiratory rates in adults is typically between 12 to 20 breaths per minute. Rates falling outside this range—particularly rates greater than 20—can initiate further evaluation and clinical consideration.
