The nurse caring for a child with mononucleosis can expect the child to exhibit which symptoms?

A. Elevated WBC and sedimentation rate: While these may be mildly elevated due to inflammation, they are nonspecific findings and not diagnostic for mononucleosis, which requires confirmation with viral-specific tests. B. Increased BUN and serum creatinine: Elevated kidney function markers are not typically associated with mononucleosis and may suggest renal involvement, which is not a standard feature of this viral illness. C. Ear pain and fever: These are more commonly associated with otitis media or other ear infections rather than mononucleosis, which presents more with systemic viral symptoms. D. Positive Epstein-Barr, and malaise: Mononucleosis is caused by the Epstein-Barr virus and typically presents with symptoms such as fatigue, malaise, fever, sore throat, and lymphadenopathy, making this the most accurate option.
