Neonatal Nurse Practitioner Practice Exam

What is the normal tidal volume range for neonates?

1. 1-2 mL/kg

2. 4-6 mL/kg

3. 7-10 mL/kg

4. 12-15 mL/kg

The correct answer is: 4-6 mL/kg

The normal tidal volume range for neonates is typically between 4 to 6 mL per kilogram of body weight. This range is appropriate for maintaining adequate oxygenation and ventilation in these patients. In the neonatal population, the lungs are still developing, and their tidal volumes are much lower compared to older children and adults. The specified volume ensures that ventilatory support, whether mechanical or spontaneous, is delivered at a level that is effective yet gentle enough to accommodate the delicate physiology of neonates. Understanding tidal volume is crucial for the care of infants, particularly those with respiratory distress or requiring mechanical ventilation. The values reflect the physiological needs of neonates, who have a smaller lung capacity and are more susceptible to ventilatory-induced lung injury. Thus, adhering to this range helps prevent complications associated with over-distension or under-ventilation in neonatal patients.
