Fundamentals of Nursing – Vital Signs Practice Test

The normal range for resting respiratory rate in healthy adults is 12 to 20 breaths per minute. This range is established based on observations of average physiological function in a resting state. A respiratory rate within this range indicates that the body is effectively exchanging oxygen and carbon dioxide, which is vital for maintaining homeostasis.

Rates lower than 12 breaths per minute may suggest bradypnea, which can indicate respiratory conditions or issues stemming from central nervous system depression, while rates higher than 20 may point to tachypnea, often seen in conditions requiring increased metabolic demand or in response to various clinical situations. Understanding the normal ranges helps healthcare professionals assess a patient's respiratory status and identify deviations that might indicate underlying health concerns.
