Which action should the nurse take to reduce the risk of ventilator-associated pneumonia in a client with an endotracheal tube receiving mechanical ventilation?
Correct Answer: C
Rationale: The correct answer is C: Brush the client's teeth with a suction toothbrush every 12 hours. This is crucial in reducing the risk of ventilator-associated pneumonia as it helps prevent the buildup of bacteria in the oral cavity, which can be aspirated into the lungs. Brushing the teeth regularly maintains oral hygiene, decreasing the chances of infection.
A: Positioning the head of the client's bed flat can increase the risk of aspiration and pneumonia.
B: Turning the client every 4 hours is important for preventing pressure ulcers but does not directly reduce the risk of ventilator-associated pneumonia.
D: Providing humidity within the ventilator tubing is important for preventing mucous plugs but does not directly address oral hygiene, which is key in preventing pneumonia.
