Explanation

Respiratory distress syndrome (RDS) is the most frequent and immediate complication in preterm infants, as stated in major pediatric and obstetric textbooks.
The primary cause is the structural and functional immaturity of the lungs, specifically a deficiency in a substance called surfactant.
Without sufficient surfactant, the alveoli (air sacs) collapse at the end of each breath, leading to poor oxygenation, increased work of breathing, and potential respiratory failure.
This makes it the primary and most common condition for which a nurse must monitor a preterm infant immediately following birth.

Option A: While intraventricular hemorrhage (IVH) is a significant risk in preterm infants due to the fragile germinal matrix in the brain, its incidence is lower than that of respiratory distress syndrome.
Option B: Brain damage is typically a severe consequence or secondary complication resulting from other primary issues like severe hypoxia (often from RDS) or significant hemorrhage (IVH), rather than being the most common initial problem.
Option D: Aspiration of mucus can cause respiratory difficulty, but it is an external event and not the intrinsic, hallmark complication of prematurity. RDS due to surfactant deficiency is far more common.

Clinical Relevance

Nursing practice connection: Use the key finding related to Common complications in preterm infants and related nursing assessment to guide bedside assessment, documentation, and the next nursing action.
Rapid identification of respiratory distress by the nurse is critical for initiating timely interventions, such as providing supplemental oxygen, applying continuous positive airway pressure (CPAP), and preparing for surfactant administration. These actions can prevent severe hypoxia and reduce the risk of long-term complications like brain damage.
A key preventive measure is the administration of antenatal corticosteroids (e.g., betamethasone) to mothers at risk of preterm delivery, which accelerates fetal lung maturation and surfactant production.
What if? If the preterm infant with RDS also develops a persistent heart murmur and bounding pulses, the nurse should suspect a patent ductus arteriosus (PDA). This condition can worsen respiratory distress by increasing blood flow to the lungs, requiring specific medical management (e.g., indomethacin) or surgical closure.

How to Approach the Question

First, identify the key elements of the question: the patient is a 'preterm infant' and the question asks for the 'most common complication' a nurse must monitor.
Recall the major physiological challenges of prematurity. Preterm infants have immature organ systems across the board.
Consider which organ system's immaturity poses the most immediate and frequent threat after birth. The lungs are among the last organs to achieve full functional maturity.
Evaluate the options in this context. Respiratory distress is a direct result of lung immaturity. Hemorrhage (IVH) and brain damage are also significant risks but are statistically less frequent as the primary, initial complication. Aspiration is an event, not an intrinsic condition of prematurity.
Conclude that respiratory distress due to surfactant deficiency is the highest-incidence problem and therefore the correct answer.
