Emergency Medical Technician (EMT) Intermediate Practice Exam

What is a common complication of suctioning a patient?

1. Increased blood pressure

2. Hypoxia

3. Hyperventilation

4. Hyperglycemia

The correct answer is: Hypoxia

Suctioning a patient is a procedure often performed to clear the airway of secretions or obstructions. One significant complication associated with this intervention is hypoxia, which occurs when there is an insufficient supply of oxygen reaching the tissues. During suctioning, it's possible for oxygen levels to drop, particularly if the procedure is prolonged or if the patient is not adequately oxygenated before and after suctioning. The act of suctioning can displace air and interfere with normal breathing, leading to a decreased oxygen saturation in the blood, and potentially causing the patient to experience hypoxia. This risk is heightened in patients with pre-existing respiratory conditions or those who are already struggling to breathe. Effective suctioning techniques often include pre-oxygenation and careful monitoring of the patient's oxygen status to mitigate this risk. Understanding the potential for hypoxia is vital for EMTs, as it informs their approach to airway management and ensures they take appropriate measures to maintain patients' oxygen levels during interventions.
