Which statement about a normal respiratory rate in a child is true?

• A. It is never observed in a fatigued child.
• B. It may be observed if the child has been breathing rapidly with increased work of breathing and is becoming fatigued.
• C. It requires an abnormally low oxygen saturation.
• D. It indicates a stable condition with no distress.

Answer: (B)

A normal respiratory rate does not guarantee stability in a child. In respiratory illness, tachypnea is a common early sign of increased work of breathing, but as fatigue sets in, the child may tire and the rate can appear normal or even slow, even though distress and effort remain. This means you can observe a normal rate in a child who has been breathing hard and labored but is now fatigued. It’s essential to assess the whole picture—work of breathing, use of accessory muscles, nasal flaring, retractions, mental status, and oxygen saturation—rather than relying on the rate alone. So, the statement that a normal rate may be seen when the child has been tachypneic and is becoming fatigued is true. The other notions—that a normal rate is never seen in fatigue, that it requires low oxygen saturation, or that it indicates no distress—aren’t reliable indicators on their own.
