The Mother of a 6-Year-Old Child Brings Her Daughter to the Pediatrician's

The mother of a 6-year-old child brings her daughter to the pediatrician's office because she has had a sore throat, cough, and fever for several days. She reports a fever up to 104°F that worsens at night, but seems to respond to treatment with acetaminophen. The child has not been eating or drinking well because she says, "it hurts to swallow." She is ill appearing, and does not seem interested in playing with the toys that are in the examination room. The physician notes a thick, white exudate on both of the patient's tonsils, which also seem enlarged. A throat culture and complete blood count with differential is ordered.

A) This is a normal examination of the posterior cervical chain lymph nodes.
B) This examination is consistent with a systemic infection.
C) This examination is consistent with a localized infection.
D) This examination is definitive for an oncologic diagnosis.
