A nurse is planning to perform nasotracheal suction for a client who has COPD and an artificial airway. Which of the following actions should the nurse take?

Choice A rationale Limiting each suction pass to 25 seconds is an unsafe practice. Prolonged suctioning can lead to hypoxemia, which is a significant risk for a client with COPD. The recommended duration for each suction pass is much shorter, typically 10 to 15 seconds, to minimize the risk of complications such as oxygen desaturation, arrhythmias, and mucosal trauma. Choice B rationale Performing suctioning for up to four passes is excessive and can cause mucosal damage, bleeding, and significant hypoxemia. The recommended practice is to limit the number of suction passes to as few as possible, usually two to three, to avoid trauma to the airway mucosa and reduce the risk of a client's oxygen saturation dropping to dangerous levels. Choice C rationale Applying suction to the catheter when advancing it into the trachea is an incorrect and harmful action. Applying suction during catheter insertion can cause significant trauma to the delicate tracheal mucosa, potentially leading to bleeding and increased risk of infection. Suction should only be applied intermittently and while withdrawing the catheter to remove secretions. Choice D rationale Preoxygenating the client with 100% oxygen for up to 3 minutes before suctioning is a critical safety measure, especially for a client with COPD. This action helps to maximize the oxygen saturation in the client's blood, creating an oxygen reservoir that mitigates the risk of hypoxemia and desaturation during the suctioning procedure, which briefly interrupts normal ventilation.
