Ans:
B

Feedback:

Fever and painful, palpable lymph nodes are nonspecific inflammatory conditions; leukocytosis is also common but is a particular hallmark of bacterial infection. Neutrophilia also indicates a bacterial infection, whereas increased levels of other leukocytes would indicate other etiologies. The shift to the left--the presence of many immature neutrophils--indicates that the infection is severe, because the demand for neutrophils exceeds the supply of mature cells.
