You are providing nursing care to a preterm newborn baby. Which assessment finding would alert the nurse to the possibility of Respiratory Distress Syndrome?

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2019

Explanation

Tachypnoea (respiratory rate greater than 60/min) and retractions (chest wall sinking) are hallmark signs of increased work of breathing in newborns.
These symptoms are a direct result of the underlying pathophysiology of RDS in preterm infants: surfactant deficiency leads to alveolar collapse (atelectasis) and decreased lung compliance.
The infant attempts to compensate for poor oxygenation and stiff lungs by breathing faster (tachypnoea) and using accessory muscles (causing retractions).
Other classic signs that often accompany these are nasal flaring and expiratory grunting.

Option B: Bradypnoea (slow breathing) is the opposite of the expected initial response. It is a late and ominous sign indicating respiratory muscle fatigue and impending respiratory failure.
Option C: These are highly non-specific signs in a newborn. They can indicate a wide range of problems, including sepsis, hypoglycemia, pain, or neurological issues, and are not specific to respiratory distress.
Option D: While cyanosis is a sign of hypoxia seen in RDS, an 'incessant cry' is not characteristic. An infant with significant RDS typically has a weak cry or an expiratory grunt due to the effort required to breathe.

Clinical Relevance

Nursing practice connection: Use the key finding related to Assessment of Respiratory Distress Syndrome (RDS) in preterm newborns to guide bedside assessment, documentation, and the next nursing action.
Early recognition of tachypnoea and retractions is a critical nursing responsibility. Prompt intervention can prevent the progression to respiratory failure.
Nurses use tools like the Silverman-Anderson score to objectively assess and document the severity of respiratory distress, which guides medical interventions like CPAP or surfactant administration.
What if? If a preterm infant on CPAP for RDS suddenly develops bradypnoea and hypotension, the nurse must immediately suspect a complication like a pneumothorax or worsening sepsis and escalate care for potential intubation and chest drain insertion.

How to Approach the Question

First, identify the key elements in the question: the patient is a 'preterm newborn' and the condition is suspected 'Respiratory Distress Syndrome'.
Recall the core pathophysiology of RDS: it's caused by a deficiency of surfactant, leading to stiff lungs that are hard to inflate.
Think about how the body would compensate for this. To overcome stiff lungs and poor gas exchange, the infant must work harder to breathe.
Evaluate each option based on whether it represents 'increased work of breathing'.
Tachypnoea (breathing fast) and retractions (using extra muscles) are direct signs of increased work of breathing. This makes it the most likely answer.
Eliminate other options: bradypnoea is a sign of failure, not initial distress, and other symptoms are either non-specific or atypical for RDS.

Concept Tested & Keywords

Concept Tested: Assessment of Respiratory Distress Syndrome (RDS) in preterm newborns.
Stem keywords: preterm newborn, nursing care, assessment finding, Respiratory Distress Syndrome
Lead-in keywords: alert the nurse
Clinical cues: The patient being a 'preterm newborn' is the most significant cue, as this population is at the highest risk for RDS due to immature lung development and surfactant deficiency.
