Answer to Question 1

ANS: D
When all six criteria are used, a score >6 is considered evidence of the presence of VAP. It is generally accepted that measurements of the CPIS should be performed at the beginning of anti-biotic therapy and after 2-3 days to reevaluate the effectiveness of the treatment.

Answer to Question 2

ANS: C
The predominant gram-positive bacterium that causes VAP is methicillin-resistant Staphylococcus aureus (MRSA). Pseudomonas aeruginosa is a gram-negative bacterium.
