Answer to Question 1
B
Feedback:
Microorganisms may become pathogens in hosts whose defense mechanisms are impaired. Opportunistic infections are likely to occur in people whose defenses are compromised due to human immunodeficiency virus (HIV) infection. This is not characterized as a nosocomial infection (hospital-acquired infection) or a secondary infection. The infection was likely to have been acquired in the community, but the patient's HIV diagnosis means that it would be considered to be an opportunistic infection.
Answer to Question 2
C
Feedback:
A continuous infusion of lidocaine IV after a bolus is 1 to 4 mg/min. The administration of 0.25 to 0.75 mg/min would be too small of a dosage. The administration of 10 to 20 or 6 to 8 mg/min would be too large.
