A nurse is caring for a newborn who was delivered via cesarean section 2 hours ago. Which assessment finding would be most indicative of transient tachypnea of the newborn (TTN)?
1Expiratory grunting and nasal flaring with a respiratory rate of 45 breaths per minute
2Tachypnea with a respiratory rate of 80 breaths per minute and mild intercostal retractions✓ 정답
3Central cyanosis with bradycardia and poor muscle tone
4Apneic episodes lasting 15-20 seconds with bradycardia
해설
TTN is characterized by tachypnea (RR >60) with mild retractions, common after cesarean section without labor. Expiratory grunting suggests RDS, central cyanosis/bradycardia indicates severe distress, and apneic episodes are typical of apnea of prematurity.
