Kettering NPS Practice Exam 2026 – Complete Prep for Neonatal/Pediatric Specialist Test

For a 32-week gestation-age neonate presenting with a SpO2 of 74% and a pH of 7.24, the situation indicates severe respiratory distress and potential acidosis, both of which require immediate intervention. In this case, intubation and initiation of mechanical ventilation is appropriate for several reasons.

A SpO2 of 74% indicates significant hypoxemia, meaning the neonate is not receiving enough oxygen to the tissues, which can lead to organ dysfunction and other severe complications. Alongside this, a pH of 7.24 suggests acidemia, indicating a severe imbalance in the body’s acid-base status. This combination of low oxygen saturation and acidemia necessitates immediate respiratory support beyond what a noninvasive method might provide.

Intubation allows for a secure airway and enables controlled mechanical ventilation, ensuring adequate oxygenation and ventilation to potentially correct the metabolic acidosis indicated by the low pH. It is crucial to restore adequate oxygen levels and remove carbon dioxide efficiently in this critically ill neonate, preventing further deterioration.

In contrast, options that involve less invasive measures like nasal CPAP or simply continuing monitoring would not adequately address the severe hypoxemia and acidemia present in this case. Nasal
