What is the normal respiratory rate for a child aged 3-5 years?

The normal respiratory rate for a child aged 3-5 years is 18-35 breaths per minute, making this the correct choice. Children in this age group have a higher metabolic rate compared to adults, which correlates with faster breathing rates to accommodate their body's oxygen demands.

As children grow, their respiratory patterns can change significantly, with younger children generally exhibiting higher respiratory rates that gradually slow as they age and develop. The range of 18-35 breaths per minute captures the normal variance found in this age group, taking into account factors such as activity level and health status.

Understanding these physiological norms is crucial in emergency nursing, as deviations from the expected respiratory rates can indicate underlying health problems. It allows nurses to assess respiratory function quickly during clinical evaluations or emergency situations.
