Which action is commonly driven by nursing staff to prevent VAP?

• A. Elevating the head of the bed
• B. Oral care
• C. Hand hygiene
• D. Ventilator pressure setting adjustments

Answer: (C)

Preventing ventilator-associated pneumonia hinges on stopping microbes from traveling to the lungs, and the most effective way nurses do this is through strict hand hygiene. Clean hands before any patient contact, after contact with the patient, and before touching the ventilator circuit break the chain of infection at its first link, directly reducing the chance of introducing bacteria into the airway. Elevating the head of the bed is important and commonly done by nursing staff because it lowers aspiration risk, but it can be limited by patient condition. Oral care helps lower the number of bacteria in the oropharynx, another key preventive step typically led by nurses as part of the care bundle, though it is one piece of a broader strategy. Adjusting ventilator pressure settings generally involves the respiratory team and physicians, not nursing alone. Overall, hand hygiene is the foundational, consistently nursing-driven action to prevent VAP.
