Which finding would alert the nurse to suspect that a newborn is experiencing respiratory distress?

Choice A rationale A respiratory rate of 50 breaths/minute falls within the expected normal range for a healthy full-term newborn, which is typically 30 to 60 breaths/minute. Therefore, this finding alone does not indicate respiratory distress, which is usually signaled by rates consistently below 30 or above 60. Tachypnea (rate > 60) is a more common sign of distress, reflecting the infant's attempt to improve oxygenation. Choice B rationale Acrocyanosis, which is the blueness of the hands and feet, is a common and usually transient finding in newborns due to sluggish peripheral circulation and vasomotor instability. It is considered a normal finding in the first 24 to 48 hours of life. Central cyanosis, which involves the mucous membranes and trunk, is a more critical sign of inadequate oxygenation and severe respiratory distress. Choice C rationale Asymmetrical chest movement, often referred to as paradoxical breathing, occurs when one side of the chest moves differently from the other during respiration. This is a significant abnormal finding that may indicate a condition like pneumothorax, diaphragmatic hernia, or atelectasis, all of which compromise effective lung expansion and gas exchange, leading to respiratory distress. Choice D rationale Short periods of apnea, defined as cessation of breathing lasting less than 15 seconds, are considered a normal variation in a newborn's breathing pattern, known as periodic breathing. Apnea lasting 15 seconds or more, or any apnea accompanied by bradycardia or cyanosis, is a concerning sign and would alert the nurse to potential respiratory or central nervous system issues.
