Explanation
Choice D is correct. Condensation naturally forms in ventilator circuits due to humidified air. This moisture poses a risk for bacterial colonization, which can lead to ventilator-associated pneumonia (VAP) if it flows back into the airway. Best practice is to drain this condensation into a designated trap or receptacle periodically.
Choice A is incorrect. Current evidence-based guidelines no longer support this practice. Saline instillation does not improve secretion clearance and may cause harm. This harm may include reduced oxygen saturation (desaturation) and increased risk for pulmonary infection.
Choice B is incorrect. The correct position for the ET tube tip is typically 2 cm above the carina, not 4 cm. A tube positioned too high can result in ineffective ventilation or inadvertent extubation.
Choice C is incorrect. The cuff must remain inflated to maintain a closed ventilatory circuit, especially when using PEEP. Deflating the cuff can lead to loss of tidal volume, aspiration, and impaired oxygenation.
