Answer to Question 1

ANS: C
For higher risk patients with these comorbidities, acceptable alternatives include an IV be-ta-lactam plus an IV or oral macrolide or doxycycline; alternatively, a parenteral fluoroquinolone may be used alone.

Answer to Question 2

ANS: B
Blood cultures should be obtained in hospitalized patients with community-acquired pneumonia and may be helpful in establishing the diagnosis in patients with typical bacterial pathogens. Blood cultures are positive in approximately 30 of patients with pneumococcal pneumonia and in up to 70 of those with H. influenzae pneumonia.
