Which pathogen is responsible for this presentation?
A. Human Herpesvirus 6
B. Parvovirus B19
C. Coxsackievirus A16
D. Group A Streptococcus
Correct Answer: B. Parvovirus B19

carotid arteries. What is the most likely diagnosis?
A. Mitral valve prolapse
B. Aortic stenosis
C. Aortic regurgitation
D. Tricuspid regurgitation
Correct Answer: B. Aortic stenosis

murmur heard best at the right upper sternal border (second ICS) with
radiation to the neck. It is often associated with symptoms of "SAD":
Syncope, Angina, and Dyspnea.

($102$ cm) in men; Triglycerides $\ge 150$ mg/dL; HDL $< 40$ mg/dL
, (men) or $< 50$ mg/dL (women); BP $\ge 130/85$ mmHg; and Fasting
Glucose $\ge 100$ mg/dL.
