Indications for incentive spirometry include:

a. post-abdominal surgery.
b. respiratory muscle weakness.
c. optimization of bronchodilator therapy.
d. inability to effectively deep breathe.

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.
