A nurse is caring for a client in respiratory distress. The health care provider orders oxygen via a nonrebrear mask. Which mask should nurse obtain to implement oxygen order?

Correct Answer:- Option 4 (Non-rebreather mask)
Rational:-

• A non-rebreather mask can accurately deliver high concentrations of oxygen (>90%). It cannot be used with a high degree of humidity.
• Option 1: This is a simple face mask. It delivers low to medium concentrations of oxygen (40% to 60%) by adjusting the oxygen flow rate to 6 to 12 L/min.
• Option 2: This is a Venturi mask. It can deliver precise high-flow rates of oxygen. Concentration and liter flow are marked on the mask apparatus; it can be adjusted to deliver concentrations of 24%, 28%, 31%, 35%, 40%, or 50% oxygen.
• Option 3: This is a face tent. It delivers an imprecise amount of oxygen. It is designed to provide moderate to high-density humidification.
