AACN Essentials of Critical Care Nursing Practice Test

The action being tested is suctioning the upper airway to physically remove secretions. By using a suction device through the mouth or through an artificial airway (like an endotracheal or tracheostomy tube), secretions are cleared from the pharynx or the airway lumen itself. This directly prevents obstruction and keeps the airway open, which supports unimpeded airflow and effective gas exchange.

Understanding the context helps: when a patient has an artificial airway, secretions tend to accumulate above the tube and can quickly block airflow if not cleared. Suctioning removes these secretions, reducing the risk of hypoxia, atelectasis, and infection. It’s performed with sterile technique for airway suctioning, typically with brief passes and adequate preoxygenation to minimize desaturation, and monitored for potential adverse effects such as mucosal injury or vagal responses.

Observing sputum color is an assessment of mucus but does not maintain patency. Administering bronchodilators widens airways but doesn’t physically remove secretions. Endotracheal tube size and position matter for airflow but do not actively remove secretions to maintain patency.
