Answer to Question 1
ANS: A
Abdominal surgery predisposes a patient to the development of pulmonary atelectasis. Patients with respiratory muscle weakness or the inability to effectively deep breathe will not be able to perform incentive spirometry and therefore will not benefit from its use. Incentive spirometry is not used to optimize bronchodilator therapy.
Answer to Question 2
ANS: B
A vital capacity of less than 10 mL/kg demonstrates that the patient is unable to breathe deeply, effectively rendering the patient unable to perform the maneuver that is necessary to achieve pos-itive results. Incentive spirometry is indicated for post-thoracic surgery and restrictive pulmonary disease. If a patient has an inspiratory capacity greater than predicted, that patient would be able to perform incentive spirometry.
