A nurse is teaching a client who is going home on continuous liquid oxygen therapy. The client asks the nurse, "How do I know when to refill the oxygen tank?”. Which of the following responses should the nurse give?
"You should refill the tank when it feels light and empty.”.
"You should refill the tank when the pressure gauge reads below 500 psi.”.
"You should refill the tank when you hear a hissing sound from the valve.”.
"You should refill the tank when an alarm sounds from the regulator.".
The Correct Answer is B
Choice A rationale:
Refilling the oxygen tank based on the client's perception of it feeling light and empty is not a reliable method, as it may lead to running out of oxygen unexpectedly.
Choice B rationale:
The nurse should instruct the client to refill the oxygen tank when the pressure gauge reads below 500 psi. This is a standardized method to ensure the client does not run out of oxygen, as the pressure gauge provides an accurate measure of the remaining oxygen in the tank.
Choice C rationale:
Refilling the tank when a hissing sound is heard from the valve is not a valid method for determining the need for a refill and may result in running out of oxygen.
Choice D rationale:
Waiting for an alarm sound from the regulator to refill the tank is not recommended, as the tank could run out of oxygen before the alarm activates.

Correct Answer is B
Explanation
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.
