A surgeon writes an order for lung expansion therapy for a 28-year-old 110-lb woman who has undergone lower abdominal surgery.

a. Intermittent positive-pressure breathing at 6 to 8 breaths/min at 10 to 15 ml/kg
b. Continuous positive airway pressure ther-apy at 10 cm H2O for 24 hr
c. Positive end expiratory pressure therapy with bronchodilator and bronchial hygiene
d. Incentive spirometry 10 times an hour at an initial volume of 500 to 600 ml
