Answer to Question 1

ANS: A
Clostridium difficile are the bacteria that cause the disruption of normal flora in the gastrointesti-nal tract caused by antibiotic therapy. Pneumocystis carinii are the protozoa that cause pneumo-nia in immunocompromised patients with human immunodeficiency virus. Enterobacteriaceae spp. are the bacteria that can cause hypogammaglobulinem ia in patients with multiple myeloma.

Answer to Question 2

ANS: B
Human barriers to infection include the mechanical barriers of the skin and mucous membranes and the person's immune system. The others are preventative measures that reduce the spread of infection in health care settings.
