weeks. On physical examination, he has a temperature of

blood pressure of 95/60 mm Hg. A tender spleen tip is
palpable. Splinter hemorrhages are observed on his finger-
nails. A heart murmur is auscultated. Which of the follow-
ing infectious agents best accounts for these findings?
C) (A) Streptococcus viridans
O (B) TtTpanosoma cruzi
O © Coxsackievirus B
O (D) C. albicans
O (E) M. tuberculosis



what if it wouyld have been st.aureus in the options?
and can u justify the damage to valves in this q

my two cents...:

I think with staph aureus they would have mentioned that he's an IV drug user.and you're right, this question is incomplete..usually they do mention new murmur after dental/urological procedures/colonscopy and then give you choices.
