A client with a tracheostomy is receiving oxygen through a tracheostomy collar. What is the advantage of using a tracheostomy collar for oxygen delivery?
Provides direct oxygen delivery to the trachea.
Allows the patient to breathe room air when disconnected from the oxygen source.
Provides the highest fraction of inspired oxygen (FiO2) among low-flow systems.
Delivers a fixed amount of oxygen independent of the patient's breathing pattern.
The Correct Answer is B
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.

Correct Answer is C
Explanation
Choice A rationale:
Nasal cannula delivers oxygen through two small prongs placed in the patient's nostrils. While it is a commonly used and well-tolerated device, the FiO2 delivered can vary significantly depending on the patient's breathing pattern and respiratory rate. Thus, it does not provide the most precise and consistent FiO2.
Choice B rationale:
Simple face masks cover the nose and mouth and can provide higher FiO2 levels compared to nasal cannulas. However, the FiO2 delivered still depends on the patient's breathing pattern and the mask's fit, making it less precise and consistent than other options.
Choice C rationale:
Venturi masks are designed to deliver a specific and accurate FiO2, regardless of the patient's breathing pattern. These masks have adjustable ports to control the mix of air and oxygen, providing precise oxygen concentrations.
Choice D rationale:
Non-rebreather masks have one-way valves and a reservoir bag to deliver higher concentrations of oxygen. Although they can provide high FiO2 levels, the delivered concentration can vary based on the patient's breathing pattern and the mask's fit.
Correct Answer is D
Explanation
Choice D rationale:
The nurse should connect the nasal cannula to a humidifier first. Dry and irritated nares are common side effects of oxygen therapy via nasal cannula, and using a humidifier adds moisture to the oxygen, reducing irritation and discomfort for the patient.
Choice A rationale:
Applying petroleum jelly to the nares is not the first action to take. It might provide temporary relief, but it is essential to address the root cause of dryness, which is the lack of moisture in the oxygen delivered.
Choice B rationale:
Increasing the flow rate of oxygen is not the first step because it may not address the dryness issue. It can lead to a higher concentration of oxygen, but it won't solve the problem of dry and irritated nares.
Choice C rationale:
Changing the nasal cannula to a face mask is not necessary to address the dryness. Face masks may not be well-tolerated by some patients, and it's better to try less invasive interventions first.
