True or false, transient tachypnea is a self-limited condition that can affect infants of any gestational age?

• A. True
• B. False
• C. Only in preterm infants
• D. Only in term infants

Answer: (A)

Transient tachypnea of the newborn (TTN) is indeed considered a self-limited condition, which means that it typically resolves on its own without the need for aggressive medical intervention. This condition is characterized by rapid breathing (tachypnea) that occurs within the first hours after birth, primarily due to retained lung fluid, often seen in infants delivered by cesarean section or those who experience a delayed clearance of lung fluid.

Additionally, transient tachypnea can affect infants of any gestational age, not limited to just those who are preterm or term. Although it is more commonly observed in term or near-term infants, the condition is not exclusive to them. Preterm infants can experience TTN as well, although other respiratory issues may also be present in that population.

The self-limiting nature of TTN contributes to its classification, as most affected infants improve within a few days with supportive care, such as supplemental oxygen if needed. Thus, it is accurate to state that transient tachypnea is a self-limited condition affecting infants across a range of gestational ages.
