(Select all that apply): A client with a tracheostomy is being weaned from mechanical ventilation. Which of the following oxygen delivery devices can be used for this client?
Venturi mask.
Tracheostomy collar.
T-piece.
Aerosol mask.
Mechanical ventilator.
Correct Answer : B,C,D
Choice A rationale:
Venturi masks are not typically used with tracheostomy patients, as they are more suitable for patients with intact upper airways.
Choice B rationale:
Tracheostomy collars are specifically designed for patients with tracheostomies. They provide oxygen directly to the tracheostomy tube, making them appropriate for weaning tracheostomized patients from mechanical ventilation.
Choice C rationale:
T-piece adapters are commonly used for patients with tracheostomies to deliver oxygen. They are simple devices that deliver oxygen directly to the tracheostomy tube.
Choice D rationale:
Aerosol masks are not specifically designed for tracheostomy patients and may not provide adequate oxygen delivery for them.
Choice E rationale:
Mechanical ventilators are not an oxygen delivery device; instead, they are used to provide mechanical ventilation support to the patient and can incorporate various oxygen delivery systems.

Correct Answer is ["A","B","D"]
Explanation
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 B
Explanation
Choice A rationale:
The goal of oxygen therapy is not to provide the highest fraction of inspired oxygen (FiO2) possible. This approach can be harmful because excessively high FiO2 levels can lead to oxygen toxicity and other side effects, especially in patients with certain conditions like chronic obstructive pulmonary disease (COPD).
Choice B rationale:
The goal of oxygen therapy is to use the lowest FiO2 that achieves an acceptable blood oxygen level without harmful side effects. This approach is known as titrating the oxygen therapy to the patient's needs and helps prevent potential complications associated with excessive oxygen administration.
Choice C rationale:
Maintaining a constant FiO2 regardless of the patient's breathing pattern is not the goal of oxygen therapy. In some cases, patients may require varying FiO2 levels based on their respiratory status, so it is essential to adjust the oxygen delivery accordingly.
Choice D rationale:
Delivering a fixed amount of oxygen that is independent of the patient's condition is not the goal of oxygen therapy. Oxygen therapy should be individualized and tailored to the patient's specific needs to optimize its effectiveness and safety.
