After abdominal surgery, a young, otherwise healthy patient is unable to meet the volume set for his volume-oriented incentive spirometer. This situation is most likely due to:
a. exacerbation of bronchospasm. c. major lung collapse.
b. inadequate pain control. d. hyperventilation.
ANS: B
Patients who are recovering from abdominal or thoracic surgery might find it difficult to achieve incentive spirometry volume goals when their pain is not under control. An exacerbation of bronchospasm would most likely cause a patient to wheeze. Major lung collapse would cause res-piratory failure, and hyperventilation would cause dizziness.
