A client is admitted to the intensive care unit (ICU) with sepsis and acute respiratory distress syndrome (ARDS). The client is orally intubated and mechanically ventilated. Which intervention is most important for the nurse to include in the client's plan of care (POC)?

A. Teach communication board use. While nonverbal communication tools are helpful for intubated clients, they do not directly prevent complications associated with mechanical ventilation and ARDS. The priority in this critically ill client is to prevent ventilator-associated pneumonia (VAP) and sepsis-related complications. B. Use antiseptic solution with oral care. Clients on mechanical ventilation are at high risk for ventilator-associated pneumonia (VAP), which worsens outcomes in ARDS. Using an antiseptic solution (such as chlorhexidine) for oral care reduces bacterial colonization in the oropharynx, decreasing the risk of VAP. This intervention is a key component of ventilator bundle protocols to improve survival rates in critically ill patients. C. Recommend hours for visitation. While family support is important, setting visitation hours does not directly impact the client's recovery from ARDS and sepsis. Infection prevention and lung protection strategies take higher priority in the acute phase. D. Promote uninterrupted periods of sleep. Rest is important for critically ill clients, but preventing life-threatening complications such as VAP, sepsis progression, and oxygenation failure takes precedence. Proper oral care with antiseptics directly reduces infection risk and improves patient outcomes.
