Certified Respiratory Therapist Practice Exam

What is an appropriate intervention for patients with suspected or confirmed atelectasis?

1. Routine monitoring of respiratory rate

2. High frequency chest wall oscillation

3. Incentive spirometry

4. Antibiotic therapy

The correct answer is: Incentive spirometry

In patients with suspected or confirmed atelectasis, incentive spirometry is a highly appropriate intervention. Atelectasis refers to the collapse of part or all of a lung, which can occur due to various factors, including insufficient deep breaths. Incentive spirometry encourages patients to take deep breaths, which can help to re-expand any collapsed lung areas and prevent further atelectasis. This device can assist in promoting alveolar inflation, improving ventilation, and enhancing oxygenation. By incentivizing the patient to take deeper breaths, it also helps to mobilize secretions and decrease the risk of pulmonary complications. The other options may have their uses, but they are not as directly effective for addressing the issue of atelectasis. Monitoring respiratory rate, for example, is a routine assessment, but it does not actively encourage lung expansion. High-frequency chest wall oscillation primarily aids in the clearance of airway secretions rather than directly targeting atelectasis. Lastly, while antibiotic therapy may be indicated if there is an infection present, it does not address the mechanical aspect of lung collapse that is characteristic of atelectasis. Thus, incentive spirometry is favored as a direct intervention to facilitate lung re-expansion and improve patient outcomes.
