A nurse is preparing to suction a patient who has thick airway secretions. Which action helps reduce the risk of hypoxia during suctioning?
Correct answer: B. Preoxygenate the patient before suctioning
- A. Apply suction continuously for two minutes
- B. Preoxygenate the patient before suctioning
- C. Instill large amounts of saline routinely
- D. Place the patient flat before suctioning
Explanation
Preoxygenation increases the oxygen reserve before the brief suction procedure. Continuous prolonged suctioning and a flat position increase the risk of hypoxia, while routine saline instillation is not generally required.

About Oxygen Therapy and Airway Care
Airway care includes positioning, suctioning, coughing and deep-breathing exercises, incentive spirometry, oxygen delivery devices and humidification. Questions address indications, flow rates, safety precautions and monitoring for hypoxia or oxygen toxicity, while distinguishing nasal cannula, simple mask, non-rebreather mask and Venturi mask use.
