Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: Hypercapnia is caused by hypoventilation, which results from one or more of the following causes: (1) inadequate respiratory center drive, (2) inadequate transmission of respiratory center drive to myoneural junction, and (3) respiratory muscle weakness.
D. Incorrect response: See explanation C.

Answer to Question 2

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: The following factors contribute to malnutrition of a patient with COPD while being mechanically ventilated: (1) hypermetabolism, (2) chronic inflammatory disease, (3) increased O2 cost of breathing caused by hyperinflation and airway obstruction, (4) increased energy requirements associated with 2 agonist medications, (5) greater activity related to thermogenesis, (6) corticosteroid use leading to protein loss, and (7) decreased intake.
