The normal respiration rate for adults is typically between 12 to 20 breaths per minute, making the correct answer reflect the standard range recognized by healthcare professionals. This range indicates that an adult at rest breathes about 12 to 20 times within a minute, which is essential for adequate gas exchange and overall respiratory function.

Understanding this normal range is crucial for healthcare providers, as deviations from it can indicate potential health issues or respiratory distress. Monitoring respiration rate is a fundamental component of vital sign assessment, which is a key responsibility for CNAs.

The other ranges provided do not accurately reflect the established norms and could lead to misunderstanding when assessing a patient’s respiratory status. Recognizing the correct parameters not only aids in proper patient care but also equips CNAs with the knowledge needed to detect and report abnormalities effectively.
