The physical exam is unremarkable. Which of the following is the most appropriate next step in the management of this patient?? A: Delay the hepatitis A immunization until next visit, B: Administer the hepatitis A vaccine, C: Strep rapid antigen detection test, D: Order a complete blood count, E: Order liver function tests,  <response>: This is a question about a 2-year-old boy who presents with subjective fever but has an otherwise normal exam. The key points are that he has no significant medical history, attends daycare, and is due for a hepatitis A vaccine. The vital signs show a mildly elevated temperature but are otherwise normal. The choices include delaying or giving the hepatitis A vaccine, doing a strep test, CBC, or LFTs. Since there are no symptoms to suggest strep throat, a strep test would not be appropriate. A CBC and LFTs are broad screening tests that are not indicated given the limited symptoms. The main decision is whether to go ahead with the scheduled hepatitis A vaccine or delay it due to the possible fever. The fever is mild and the patient is otherwise well-appearing, so there is no contraindication to giving the vaccine at this visit.B: Administer the hepatitis A vaccine
