Answer to Question 1

ANS: C
Mortality varies according to the infecting agent and was highest for P. aeruginosa (61.1), Klebsiella species (35.7), Escherichia coli (35.3), and S. aureus (31.8). Mortality rates for more common pathogens were lower but still substantial and included Legionella species (14.7), S. pneumoniae (12.3), C. pneumoniae (9.8), and M. pneumoniae (1.4).

Answer to Question 2

ANS: C
Points are assigned for the presence of a number of variables, and cumulative point scores are used to stratify patients into one of five different risk groups with predictable mortality rates (Table 24-5). Of the above only respiratory alkalosis is NOT associated with increased risk of death.
