Airway Clearance Review

What is the term for the complete obstruction caused by the retention of secretions?

• Atelectasis
• Mucous plugging
• Autogenic drainage
• Pneumothorax

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

What condition warrants airway clearance therapy?

• Copious secretions
• Ability to mobilize secretions
• Presence of rib fracture on a chest X-ray
• Productive cough

What are the recommended pressure settings for Mechanical Insufflation-Exsufflation (MIE) devices?

• 10 cm H2O and -10 cm H2O
• 20 cm H2O and -20 cm H2O
• 30 cm H2O and -30 cm H2O
• 80 cm H2O and -80 cm H2O

What should be done if a patient experiences hemoptysis during chest physical therapy?

• Continue therapy while closely monitoring the patient
• Stop therapy, give oxygen

• Administer bronchodilators immediately
• Increase therapy intensity

Based on a chest radiograph showing infiltrates in the posterior basal segments of the lower lobes, what postural drainage position should be recommended?

• Prone with a pillow under the head and the bed flat
• Prone with a pillow under the abdomen
• Supine with a pillow under the knees and the bed flat
• Sitting with the legs elevated

If tolerated, how long should a specified postural drainage position be maintained?

• 3 - 15 minutes
• 20 - 30 minutes

What is not considered an outcome assessment for airway clearance therapy?

• Change in weight
• Change in vital signs
• Change in sputum color
• Change in breath sounds

What are the goals of airway clearance therapy? (Select all that apply)

• Improve pulmonary gas exchange
• Help mobilize retained secretions
