Final answer:
The client who benefits most from the oxygen analyzer is the 2-year-old with an asthma exacerbation because it is vital to monitor and maintain their oxygen levels during an attack.
Step-by-step explanation:
The pediatric nurse is seeking to determine which client would benefit most from the use of an oxygen analyzer. An oxygen analyzer is particularly valuable in situations where it's crucial to monitor and maintain precise oxygen levels for patients with respiratory issues. Considering the conditions described:
- A 2-year-old with asthma exacerbation would benefit significantly from such monitoring, as ensuring optimal oxygen levels is critical in managing asthma attacks and preventing hypoxemia.
- A 6-year-old with a broken arm, a 10-year-old with a fever, and a 15-year-old with a sprained ankle do not typically require oxygen level monitoring unless there are complications or underlying respiratory issues.
Therefore, the client that will receive the greatest benefit from the use of an oxygen analyzer is the 2-year-old with an asthma exacerbation, as maintaining proper oxygen saturation is part of critical asthma management and can prevent further respiratory distress.
