B
A nonallergic urticarial rash occasionally occurs with ampicillin and is common in patients with mononucleosis. This patient has pharyngitis, which was not diagnosed by throat culture. The NP should suspect mononucleosis and a nonallergic rash. Serum sickness and penicillin allergy are possible but less likely. A scarlatiniform rash is not urticarial.
