Answer to Question 1

ANS: A (page 372)
Cognitive Level: Recall
A. Correct response: Long-term follow-up studies on several hundred patients using NPPV for 3 to 5 years have demonstrated favorable results among patients with postpolio syndrome, various myopathies, and kyphoscoliosis. Survival among patients with amyotrophic lateral sclerosis (ALS) was less favorable because the ALS (underlying disease) progresses more rapidly than with the other pathologies.

C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.

Answer to Question 2

ANS: B (page 369)
Cognitive Level: Recall
A. Incorrect response: See explanation B.
B. Correct response: Hypoxemic respiratory failure is characterized by severe hypoxemia (Pao2/Fio2 <200), respiratory distress, tachypnea (>30 breaths/minute), tachycardia, and a non-COPD cause (e.g., ARDS), acute pneumonia, trauma, and acute pulmonary edema.
C. Incorrect response: See explanation B.
