What is the upper bound of the respiratory rate described for toddlers and infants in the material?

• A. 30-40 breaths per minute
• B. 40-60 breaths per minute
• C. 60-80 breaths per minute
• D. 12-20 breaths per minute

Answer: (B)

In pediatric breathing assessment, you look at the typical range of breaths per minute for infants and toddlers and identify the highest value within that normal range. The material describes a range that goes up to 60 breaths per minute, so the upper bound is 60 breaths per minute. This reflects how young children breathe faster than adults, with the highest normal end listed in the material.

If you count breaths and see rates at or near 60, that can be normal for these ages, but anything persistently above that may indicate tachypnea and possible distress or illness. The other range options don’t match the described upper limit for these ages, since they end at values lower or higher than 60 and don’t reflect the material’s stated boundary.
