What is the primary purpose of suctioning?

• A. To deliver medications
• B. To remove secretions, blood, or vomitus to maintain a patent airway
• C. To humidify the airway
• D. To remove foreign bodies

Answer: (B)

Keeping the airway clear by removing secretions, blood, or vomitus is the primary purpose of suctioning. When these materials accumulate, they can obstruct airflow or be aspirated into the lungs, reducing ventilation and gas exchange. Suctioning clears the airway so breaths can proceed effectively and helps prevent aspiration during airway management or in patients who can’t clear secretions on their own. It isn’t a method for delivering medications—that’s done with nebulizers or inhalers. Humidification is provided by humidified oxygen or nebulization, not suction. And while suction can remove debris, it isn’t the main tool for dealing with a foreign body, which typically requires other techniques or tools.
