In a pediatric unit assignment for a float nurse, which patient should be seen first?

The appropriate choice for which patient to see first is the 10-year-old with pneumonia receiving respiratory treatments. This patient likely requires immediate attention due to the nature and severity of pneumonia, which can lead to significant respiratory distress and complications, especially in pediatric patients.

Pneumonia can cause hypoxemia, difficulty breathing, and may necessitate close monitoring during respiratory treatments to ensure that the patient is responding well and to manage any potential deterioration. The fact that the patient is already undergoing treatments indicates an active concern for their respiratory status and the need for careful observation.

In comparison to the other patients, the 6-month-old with a severe cold, while needing care, is generally at lower risk for acute complications than one with pneumonia. The 4-year-old with a mild fever may require assessment, but this condition is typically less urgent. The 12-year-old with a sprained ankle should be evaluated as well, but this injury is not life-threatening and can be managed after more critical conditions are attended to.

Therefore, prioritizing the care for the patient with pneumonia is vital to ensure appropriate interventions are provided in a timely manner, safeguarding their health and wellbeing.
