Final answer:
The ICU nurse would monitor a 2-year-old near-drowning victim for respiratory acidosis, a condition where CO₂ accumulation leads to an excessively acidic blood pH, indicating impaired gas exchange and ventilation.
Step-by-step explanation:
The ICU nurse caring for a 2-year-old near-drowning victim monitors for several possible complications. Among them, respiratory acidosis is a significant concern. Respiratory acidosis occurs when there is an excess of carbonic acid in the blood due to an accumulation of CO₂. This condition is problematic as it indicates inadequate ventilation and impaired gas exchange, conditions that a near-drowning victim is particularly susceptible to. In such cases, blood oxygen levels may be low, and, without prompt intervention, this can quickly become life-threatening. Medical interventions for a near-drowning patient may include ventilation support and monitoring of blood gas levels to manage respiratory acidosis.
