A patient who will begin oxygen therapy has a history of sinus disorders. This patient would benefit most from which oxygen setup?
A nasal cannula
A Venturi mask
A humidifier
High oxygen flow rate
The Correct Answer is C
A. A nasal cannula: May cause further nasal irritation and is not ideal for patients with sinus disorders.
B. A Venturi mask: Provides precise oxygen delivery but does not address sinus-related discomfort.
C. A humidifier: Helps add moisture to the oxygen, reducing nasal and sinus irritation and improving comfort.
D. High oxygen flow rate: High flow rates without humidification exacerbate sinus irritation.

Correct Answer is A
Explanation
A. Start slowly and increase volume over several sessions: Gradually increasing lung volume improves compliance and helps clients build confidence with the device.
B. Be much more vigorous in increasing increments: Rapid or forceful attempts can cause hyperventilation or dizziness and are not recommended.
C. Do regular deep-breathing exercises instead: Deep breathing can be helpful but does not replace the targeted lung expansion benefits of the incentive spirometer.
D. Use another device because this one might be faulty: Device failure is rare; user education is usually more effective.
Correct Answer is C
Explanation
A. A nonrebreather mask: This provides high concentrations of oxygen (60% to 100%) and lacks precise control over oxygen delivery.
B. A simple face mask: Delivers oxygen concentrations between 40% and 60%, but the oxygen concentration varies depending on the client's breathing pattern.
C. A Venturi mask: Provides precise and consistent oxygen delivery, making it the best choice for clients needing an exact concentration of 40% oxygen.
D. A partial rebreathing mask: Delivers concentrations between 50% and 75% without precise control.
