Question

Quizplus · Accepted Answer

Jacob's symptoms of a scratchy sore throat, nonproductive cough, rhinorrhea, nasal congestion, and headache indicate an upper respiratory illness. Additionally, the normal CBC and chest X-ray results suggest a viral rather than a bacterial infection. Therefore, the best choice is viral upper respiratory illness.
