What respiratory rate (RR) is typically observed in a newborn with Transient Tachypnea of the Newborn (TTN)?

• A. 40-60 breaths per minute
• B. 60-80 breaths per minute
• C. 30-50 breaths per minute
• D. Above 80 breaths per minute

Answer: (B)

Transient Tachypnea of the Newborn (TTN) is characterized by a temporary increase in respiratory rate, primarily due to retained fetal lung fluid and a relatively immature respiratory system. In newborns affected by TTN, it's common to observe a respiratory rate that falls within the range of 60-80 breaths per minute.

This elevated respiratory rate is usually present shortly after birth and can last for several hours to a couple of days before normalizing. The increased work of breathing is a response to the physiological challenges posed by TTN, leading to a higher than usual respiratory rate compared to the standard range for healthy newborns.

In terms of the other options, a respiratory rate of 40-60 breaths per minute typically aligns with the normal range for newborns. A rate of 30-50 breaths per minute would be considered lower than expected for a newborn showing signs of respiratory distress. A rate above 80 breaths per minute may indicate more severe respiratory distress or other underlying respiratory issues, thus distinguishing TTN from other more critical conditions.
