What is the lowest expected normal respiratory rate for preschool-aged children?

For preschool-aged children, the normal respiratory rate typically ranges from 20 to 30 breaths per minute. Therefore, 20 breaths per minute represents the lower end of this expected range, making it a suitable answer for the lowest expected normal respiratory rate for this age group.

At this developmental stage, a respiratory rate of 20 breaths per minute signifies a healthy respiratory function, as children are still growing and their bodily systems are developing. Rates lower than this can indicate potential respiratory issues or other health concerns, while rates significantly higher than this can suggest distress or other complications.

Understanding that respiratory rates fluctuate with different ages is crucial for nursing practice, as it helps in accurately assessing a child's health and determining the need for further evaluation or intervention.
