(Select all that apply): A nurse is educating a group of patients about different oxygen delivery devices. Which of the following are examples of low-flow oxygen delivery systems?
Nasal cannula.
Simple face mask.
Venturi mask.
Non-rebreather mask.
Correct Answer : A,B,D
Choice A: Nasal cannula is a low-flow oxygen delivery system. It delivers a variable oxygen concentration depending on the patient's breathing pattern.
Choice B: Simple face mask is also a low-flow oxygen delivery system. It provides a variable oxygen concentration based on the patient's respiratory rate and tidal volume.
Choice C: Venturi mask is not a low-flow system. It is a high-flow oxygen delivery device that provides a fixed oxygen concentration by mixing oxygen with room air.
Choice D: Non-rebreather mask is considered a low-flow oxygen delivery system. It provides a high concentration of oxygen but does not ensure a precise oxygen concentration due to varying patient ventilation.

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.
