An obese patient had upper abdominal surgery 2 days earlier. He has a weak nonproductive cough and a pulse oximeter (SpO2) reading of 84% on room air. Which therapist-driven protocol(s) should be implemented?

1. Bronchopulmonary hygiene therapy
2. Lung expansion
3. Oxygen therapy
4. Aerosolized medication therapy
a. 1
b. 3, 4
c. 2, 3
d. 1, 3, 4

C
Upper abdominal surgery is specified as one of the clinical indications for implementation of the lung expansion protocol. The oxygen therapy protocol would be indicated since the SpO2 is less than 90% on room air.
