Final answer:
Enlarged tonsils are the physical exam finding that correlates with obstructive sleep apnea (OSA), as they can contribute to airway obstruction during sleep.
Step-by-step explanation:
The physical exam finding that correlates with obstructive sleep apnea (OSA) is enlarged tonsils. OSA is often associated with physical blockages in the upper respiratory tract, where enlarged tonsils can contribute to the obstruction of the airway during sleep. This can lead to frequent disruptions of sleep due to temporarily halted breathing, resulting in symptoms such as snoring, restless sleep, and daytime sleepiness. Treatment options include lifestyle changes, the use of a continuous positive airway pressure (CPAP) machine, and in some cases, supplemental oxygen. High blood pressure can be a consequence of OSA, but it is not a diagnostic physical exam finding for the condition itself.
