How does chest-tube care relate to pneumonia prevention?

• A. Early mobilization, deep breathing, and proper drainage reduce atelectasis and infection risk; maintain sterile dressing hygiene.
• B. Maintaining sterile dressing hygiene reduces infection risk, but early mobilization is not necessary.
• C. Bed rest is essential to prevent pneumonia.
• D. Pneumonia prevention relies on antibiotics only.

Answer: (A)

Preventing pneumonia in someone with a chest tube comes down to keeping the lung fully inflated and protecting against infection. Early mobilization and deep breathing (including incentive spirometry and purposeful coughing) help re-expand collapsed areas, improve ventilation, and clear secretions. When the lung stays open and airways stay moving, mucus is cleared more effectively and the risk of atelectasis—which can become a site for infection—drops.

Having the chest tube drainage remain patent and functioning is also crucial. Proper drainage prevents the buildup of air or fluid that can compress the lung and perpetuate atelectasis. A well-drained chest supports complete lung expansion, which lowers pneumonia risk.

Sterile dressing hygiene at the insertion site helps prevent local infection that could spread or complicate respiratory status. While this is important, pneumonia prevention is not achieved by hygiene alone; it works best in combination with keeping the lung expanded and free of infectious processes.

Other options aren’t addressing the core mechanisms. Bed rest doesn’t actively prevent pneumonia and can worsen deconditioning; antibiotics alone don’t prevent pneumonia and don’t replace efforts to optimize lung expansion and drainage.
