Answer to Question 1

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: Hypoxemic respiratory failure is caused by ventilationperfusio n abnormalities ranging from capillary shunting to alveolar dead space. Between these two ventilationperfusio n extremes are low and high ventilationperfusio n ratios. Acute atelectasis and pneumonia exemplify shunt-producing diseases. Pulmonary embolism creates alveolar dead space units, and COPD causes an array of ventilationperfusio n abnormalities (i.e., low and high conditions).

Answer to Question 2

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: Patients requiring more than 3 to 5 days of mechanical ventilation are at high risk for malnutrition and need to be evaluated for nutritional supplementation.
D. Incorrect response: See explanation C.
