A nurse is caring for a patient who requires oxygen therapy due to hypoxia. What is the goal of oxygen therapy for this patient?

Choice A rationale:

Although a tracheostomy collar provides oxygen directly to the trachea, the advantage specified in the question is related to the ability to breathe room air when disconnected from the oxygen source.

Choice B rationale:

This is the correct answer because a tracheostomy collar has an opening that allows the patient to breathe room air when the oxygen source is disconnected. This feature enables the patient to participate in activities without continuous oxygen delivery, promoting mobility and reducing the feeling of being tethered to an oxygen supply.

Choice C rationale:

A tracheostomy collar does not provide the highest fraction of inspired oxygen (FiO2) among low-flow systems. High-flow systems, such as non-rebreather masks or venturi masks, typically provide the highest FiO2.

Choice D rationale:

A tracheostomy collar does not deliver a fixed amount of oxygen independent of the patient's breathing pattern. Instead, it provides supplemental oxygen in response to the patient's inspiratory effort, which is a characteristic of low-flow oxygen delivery systems.

Choice A rationale:

The nurse should instruct the patient to avoid smoking or being near open flames while using oxygen. Oxygen supports combustion, and smoking or exposure to flames can lead to a fire hazard.

Choice C rationale:

Checking the position of the oxygen delivery device frequently is important to ensure proper oxygen delivery and avoid any displacement or obstruction that may compromise the therapy's effectiveness.

Choice D rationale:

Instructing the patient to report any signs of hypoxia (low oxygen levels) or hypercarbia (high carbon dioxide levels) to the provider is crucial for early detection of potential complications and appropriate management.

Choice E rationale:

Instructing the patient to adjust the flow rate of oxygen as needed allows them to respond to varying oxygen requirements, especially during activities or changes in their respiratory condition.

Choice B rationale:

Using cotton or wool clothing and bedding is not a recommended instruction for oxygen therapy. Synthetic materials are preferred as they are less likely to catch fire compared to cotton or wool.
