What is the significance of assessing lung sounds in immobile patients?

• A. To monitor heart rate
• B. To measure blood glucose
• C. To diagnose liver disease
• D. To detect potential respiratory complications such as atelectasis

Answer: (D)

Assessing lung sounds in immobile patients targets a high risk of respiratory complications from limited movement. Immobility leads to shallow breaths, reduced cough effectiveness, and mucus retention, which can cause alveolar collapse (atelectasis) and set the stage for pneumonia. By listening for changes in breath sounds—areas with diminished sounds, crackles indicating collapsed or fluid-filled alveoli, or wheezes/rhonchi from secretions—a nurse can detect early signs of atelectasis or developing infection before symptoms worsen. This enables timely interventions such as incentive spirometry, deep-breathing and coughing exercises, airway clearance techniques, hydration, and repositioning to improve ventilation and prevent progression. Other monitoring like heart rate, blood glucose, or liver assessment don’t directly address respiratory status through auscultation.
