When collecting an infant's screening card, O2 levels, bilirubin, and DNA, what should be prioritized for collection?

The correct response emphasizes the importance of oxygen levels, particularly in an infant, as they are critical for assessing respiratory function and overall health. Monitoring oxygen (O2) levels is a vital part of neonatal care because low oxygen saturation can lead to serious complications, including hypoxia, which can impact development and even be life-threatening. It is typically the first measurement taken in emergent situations to ensure that the infant is receiving adequate oxygenation.

In contrast, while bilirubin levels, DNA, and the screening card are also significant in newborn assessments, they are usually considered after ensuring that the infant's immediate health needs, such as oxygenation, are addressed. Bilirubin testing is crucial to monitor for jaundice but is often determined after assessing respiratory status. DNA collection may be necessary for genetic screening but is not urgent compared to ensuring the infant's vital signs are stable. The screening card, which might include various metabolic tests, is essential for long-term health monitoring but is secondary to immediate life-sign measurements like oxygen levels. Thus, prioritizing oxygen levels reinforces the emphasis on patient safety and foundational medical assessments in pediatric care.
