Answer to Question 1
2
Rationale: The clinical manifestations of COPD are several, including hypoxemia; hypercapnia; dyspnea on exertion and at rest; oxygen desaturation with exercise; use of accessory respiratory muscles; and prolonged exhalation. Chest x-ray results indicate a hyperinflated chest and may indicate a flattened diaphragm if the disease is advanced.
Answer to Question 2
1
Rationale: A reactive nonstress test is a normal result. To be considered reactive, the baseline must be within normal range (110 to 160 beats/min with good long-term variability), and there must be two or more fetal heart rate accelerations of at least 15 beats/min, each with a duration of at least 15 seconds, in a 20-minute interval. Therefore, the other options are incorrect.
