What is the recommended therapy for managing suspected atelectasis in an alert patient post-abdominal surgery?

1. Chest physiotherapy

2. Incentive breathing therapy

3. High-flow oxygen therapy

4. Continuous positive airway pressure

The correct answer is: Incentive breathing therapy

In the management of suspected atelectasis in an alert patient following abdominal surgery, incentive breathing therapy is the recommended therapy as it promotes deep breathing and helps the patient achieve maximum lung expansion. This approach is particularly beneficial in post-operative settings, where the risk of atelectasis is increased due to factors like pain, reduced mobility, and shallow breathing patterns. Incentive breathing therapy utilizes devices that encourage deep inhalation, thereby enhancing lung recruitment and maintaining alveolar inflation. This technique not only improves gas exchange but also mobilizes secretions, reducing the risk of complications associated with atelectasis. While chest physiotherapy can assist in the clearance of pulmonary secretions, its primary focus is on facilitating airway clearance rather than directly preventing atelectasis. High-flow oxygen therapy is beneficial for patients experiencing hypoxemia, but it does not address the underlying lung expansion issue related to atelectasis. Continuous positive airway pressure (CPAP) may be utilized in certain scenarios such as in patients with obstructive sleep apnea or significant hypoxemia, yet it is not the first-line therapy for suspect atelectasis itself. Therefore, incentive breathing therapy is the most appropriate choice for this situation, effectively aiding in lung expansion and reducing the risk of complications post-s
