The nurse is teaching the spouse of a client on mechanical ventilation about measures to prevent ventilator associated pneumonia. Which of the following statements by the family would indicate to the nurse that the family would indicate to the nurse that the family needs additional instruction?

A. Administering stress ulcer prophylaxis (such as a proton pump inhibitor or H2 blocker) is a component of VAP prevention bundles, as gastric acid suppression reduces the risk of aspiration-related pneumonia. This statement is correct and does not indicate misunderstanding. B. Elevating the head of the bed 30–45° is a key VAP prevention measure, as it decreases risk of aspiration of gastric contents. This statement demonstrates proper understanding. C. Continuous deep sedation is not recommended for VAP prevention. Over-sedation increases immobility, delays weaning, and increases the risk of VAP. The preferred practice is daily sedation interruption or light sedation, allowing assessment of readiness for weaning and reducing complications. This statement indicates the family needs additional teaching about sedation practices. D. Low-dose anticoagulation (e.g., heparin) is used for venous thromboembolism (VTE) prophylaxis in mechanically ventilated patients and is part of standard critical care bundles. It does not directly prevent VAP but is appropriate care.
