A nurse is caring for a patient who is receiving oxygen therapy via non-rebreather mask at 15 L/min. The nurse should recognize that this device has which of the following advantages?(Select all that apply)
It delivers the highest concentration of oxygen among low-flow systems.
It prevents the patient from rebreathing exhaled air.
It provides consistent and precise oxygen delivery.
It allows room air to enter through exhalation ports.
It minimizes the risk of carbon dioxide retention.
Correct Answer : A,B,E
The correct answer is choice a, b, and e.
Choice A rationale:
A non-rebreather mask is designed to deliver a high concentration of oxygen, often deemed the highest among low-flow systems. It achieves this through a reservoir bag that is filled with pure oxygen, which the patient breathes in without the dilution of room air.
Choice B rationale:
This mask has one-way valves that prevent the patient from rebreathing exhaled carbon dioxide. The exhaled air exits through side ports, ensuring that only oxygen from the reservoir is inhaled.
Choice C rationale:
While a non-rebreather mask delivers a high concentration of oxygen, it does not provide a consistent and precise oxygen delivery compared to devices like a Venturi mask, which are designed to deliver a specific and constant oxygen concentration.
Choice D rationale:
The design of a non-rebreather mask does not allow room air to enter through the exhalation ports. The one-way valves are there to ensure that exhaled air does not enter the reservoir bag and that room air does not mix with the oxygen being inhaled.
Choice E rationale:
By delivering a high concentration of oxygen and preventing the rebreathing of exhaled gases, a non-rebreather mask minimizes the risk of carbon dioxide retention, which can be a concern with other oxygen delivery systems that allow for the rebreathing of a portion of exhaled air.
In summary, the non-rebreather mask is advantageous for its ability to deliver a high concentration of oxygen and prevent the rebreathing of exhaled air, which also minimizes the risk of carbon dioxide retention. It is not designed for precise oxygen delivery, nor does it allow the mixing of room air during inhalation.

Correct Answer is C
Explanation
Choice A rationale:
The nurse should not immediately check the patient's oxygen level with a finger device because the priority is to address the hissing sound from the mask and the patient's pale skin color, which could indicate inadequate oxygen delivery.
Choice B rationale:
Instructing the patient to breathe more deeply and slowly won't address the issue of the hissing sound and the possible oxygen delivery problem. The nurse should address the equipment issue first.
Choice C rationale:
This is the correct choice. The nurse should inform the patient that there is a problem with the mask, and it needs to be fixed promptly to ensure adequate oxygen therapy.
Choice D rationale:
Lowering the flow rate may not be appropriate until the nurse has assessed and resolved the problem with the mask. It's essential to troubleshoot the equipment first.
Correct Answer is D
Explanation
Choice A rationale:
Monitoring the patient's respiratory rate, depth, rhythm, and effort is crucial for assessing the effectiveness of oxygen therapy and ensuring proper oxygenation through the tracheostomy collar.
Choice B rationale:
Educating the patient on how to use and care for the tracheostomy collar is essential to ensure the patient's safety and compliance with the therapy.
Choice C rationale:
Implementing safety measures to prevent fire hazards from the oxygen source is crucial, especially when oxygen is delivered via tracheostomy collar, which may have increased oxygen flow rates.
Choice D rationale:
This is the correct choice. All the provided interventions (monitoring respiratory parameters, patient education, and safety measures) are essential components of the plan of care for a patient with a tracheostomy who requires oxygen therapy.
