護理師正在照顧一位接受機械通氣的病人。下列哪項評估發現需要立即介入以預防呼吸器相關肺炎（VAP）？
A nurse is caring for a client receiving mechanical ventilation. Which assessment finding requires immediate intervention to prevent ventilator-associated pneumonia (VAP)?
- AVentilator settings are within prescribed parameters呼吸器設定在處方參數範圍內
- BClient is receiving continuous sedation病人接受連續鎮靜治療
- CClient has increased respiratory secretions and coarse crackles✓ 正解病人呼吸分泌物增加且有粗糙囉音
- DEndotracheal tube is securely taped氣管內管已牢固固定
呼吸器相關肺炎（VAP）是機械通氣病人常見且嚴重的併發症。當護理師發現病人呼吸道分泌物增加且出現濕囉音（Coarse crackles）時，代表肺部可能已發生積液或感染，若不即時清理，這些分泌物會成為細菌滋生的溫床，導致肺炎。因此，必須立即抽痰（Suctioning）並重新評估病人的肺部狀況，以防止病情進展。
Ventilator-associated pneumonia (VAP) is a common and serious complication in mechanically ventilated patients. When the nurse finds increased respiratory secretions and coarse crackles, this suggests possible fluid accumulation or infection in the lungs; if not promptly cleared, these secretions become a breeding ground for bacteria and lead to pneumonia. Therefore, suctioning must be performed immediately and the patient's lung status reassessed to prevent disease progression.
