Answer to Question 1

ANS: B
The skin and mucosal barrier have been disrupted by the burns; therefore, this patient is suscepti-ble to Pseudomonas aeruginosa. Pseudomonas aeruginosa is one of several pathogens that can affect hospitalized patients. Patients with systemic lupus erythematosus, liver failure, or vasculitis are susceptible to Streptococcus pneumoniae. Oncochemotherapy and antibiotic therapy increase a patient's susceptibility to Candida albicans and Clostridium difficile.

Answer to Question 2

ANS: B
Aspergillus fumigatus causes opportunistic fungal infections. Pneumocystis carinii is an oppor-tunistic protozoan that causes pneumonia in immunocompromised patients. Histoplasma capsu-latum can cause fungal infections in otherwise healthy individuals. Haemophilus haemolyticus is usually nonpathogenic, but on rare occasions it can cause subacute endocarditis.
