Which of the following is a common risk factor for developing pneumonia in a healthcare setting?

Developing pneumonia in a healthcare setting, particularly ventilator-associated pneumonia, is often linked to several risk factors. One of the most significant risk factors is intubation and prolonged immobilization. When patients are intubated, they have a tube inserted into their trachea to assist with breathing, which can compromise the normal protective mechanisms of the respiratory tract. The presence of this tube can lead to the aspiration of bacteria from the upper airways into the lungs, increasing the risk of pneumonia.

Furthermore, prolonged immobilization can decrease lung function and the ability to clear secretions effectively, contributing to the development of pneumonia. Patients who are unable to move or change position frequently may find it difficult to expel mucus buildup, creating an environment conducive to infection.

In contrast, regular exercise, high fluid intake, and frequent patient movement are generally associated with improved health outcomes and enhanced respiratory function, helping to reduce the risk of pneumonia rather than increase it. Therefore, the option related to intubation and prolonged immobilization correctly identifies a significant risk factor for pneumonia in healthcare settings.
