A patient presents to the clinician with a sore throat, fever of 100.7F, and tender anterior cervical lymphadenopathy. The clinician suspects strep throat and performs a rapid strep test that is negative. What would the next step be?

You have a patient who is a positive for Strep on rapid antigen testing (rapid strep test). You order amoxacillin after checking for drug allergies (patient is negative) but he returns 3 days later, reporting that his temperature has gone up, not down (101.5 F in office). You also note significant adenopathy, most notably in the posterior and anterior cervical chains, some hepatomegaly, and a diffuse rash. You decide:
a. to refer the patient.

c. that his antibiotic dosage is not sufficient and should be changed.
d. that he possibly has mononucleosis concurrent with his strep infection.
