A patient is undergoing oxygen therapy through a nasal cannula.If the patient inquires about the reason for having oxygen tubing in their nose, what explanation about the cannula should the nurse provide?

Choice A rationale

The client should lift the walker and place it down in front of her. This is because lifting the walker provides stability and support as the client moves. It’s important for the client to move the walker first, then step forward to ensure balance and prevent falls.
Choice B rationale
Walking in front of the client to guide her in moving the walker is not the best practice. The client should be allowed to set the pace and the nurse should be beside or slightly behind the client to provide assistance if needed.
Choice C rationale
Having the client move one leg forward with the walker is not the most effective way to use a walker. Both legs should move forward after the walker has been placed down in front of the client.
Choice D rationale
Making sure that the upper bar of the walker is level with the client’s waist is a good practice, but it’s not the best answer for this question. The height of the walker should be adjusted so that the handles are at the level of the client’s wrists when the client’s arms are hanging down. This allows the client to maintain a slight bend in their elbows when holding the handles.

Choice A rationale
While it’s true that a nasal cannula allows the patient to remove it for a while when it gets uncomfortable, this is not the primary reason for using a nasal cannula. The main purpose of a nasal cannula is to deliver oxygen.
Choice B rationale
A nasal cannula delivers the low concentration of oxygen that the patient needs. It is designed to provide a specific amount of oxygen, and the flow rate can be adjusted as needed.

Choice C rationale
While a nasal cannula does deliver a specific concentration of oxygen, it does not do so constantly. The amount of oxygen delivered can vary depending on the patient’s breathing rate and depth.
Choice D rationale
A nasal cannula does not deliver the highest concentration of oxygen possible. Other devices, such as non-rebreather masks, can deliver higher concentrations of oxygen.
