TTN is typically short-lasting. Which description best describes its duration?

• A. Several weeks
• B. 1-2 days
• C. 1-2 weeks
• D. 1 month

Answer: (B)

TTN is short-lived because the baby’s lungs clear the retained fetal fluid quickly after birth, and the respiratory distress improves as that fluid is absorbed. Because this resolution happens within a few days, the typical duration is about one to two days (roughly 24–48 hours). Some infants may take up to about 3 days, but it rarely extends beyond that. Longer durations—like several weeks, one to two weeks, or a full month—would suggest a different or more persistent condition rather than TTN.
