Which statement describes nursing responsibilities with a Venturi mask?

• A. Increase flow to maximum to ensure high FiO₂.
• B. Deteriorate flow when patient reports dyspnea.
• C. Ignore patient comfort if readings are normal.
• D. Ensure correct flow setting for adapter used; monitor oxygenation and patient comfort.

Answer: (D)

Delivering oxygen with a Venturi mask hinges on using a calibrated adapter to set a precise FiO2. The nurse’s responsibilities are to confirm the correct adapter is attached, set the flow to the manufacturer’s recommended rate for that adapter, and continuously monitor both the patient’s oxygenation and comfort. Each Venturi adapter is matched to a specific FiO2, and the flow must be accurate for that adapter to work as intended. If the adapter or flow isn’t correct, the delivered oxygen concentration can be off, undermining treatment and causing patient distress.

Ongoing assessment is key: monitor SpO2, respiratory effort, and work of breathing, and also listen to the patient’s comfort and tolerance. If dyspnea develops, evaluate whether the prescription is being met, check for mask leaks, and ensure the device fits properly before making any changes to therapy. Comfort matters because intolerance can lead to poor adherence and worse outcomes, so address issues like mask seal, potential need for humidification, and overall fit while keeping oxygenation within target ranges.

In short, the proper nursing approach is to ensure the correct adapter and flow are used and to monitor both oxygenation and patient comfort.
