Answer to Question 1

ANS: D
Tuberculosis is acquired by inhalation of infectious particles is the basis for a policy whereby pa-tients with suspected or proven tuberculosis who are coughing are placed in respiratory isolation, thereby minimizing the risk of disease transmission within the hospital setting.

Answer to Question 2

ANS: A
In intubated patients, chronic aspiration of colonized secretions through a tracheal cuff has been linked to the subsequent occurrence of pneumonia, which has led to the development of novel strategies to prevent hospital-acquired pneumonia, such as continuous suctioning of subglottic secretions in mechanically ventilated patients and elevation of the head of the bed.
