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?

Choice A rationale:

The nurse should not immediately check the patient's oxygen level with a finger device because the priority is to address the hissing sound from the mask and the patient's pale skin color, which could indicate inadequate oxygen delivery.

Choice B rationale:

Instructing the patient to breathe more deeply and slowly won't address the issue of the hissing sound and the possible oxygen delivery problem. The nurse should address the equipment issue first.

Choice C rationale:

This is the correct choice. The nurse should inform the patient that there is a problem with the mask, and it needs to be fixed promptly to ensure adequate oxygen therapy.

Choice D rationale:

Lowering the flow rate may not be appropriate until the nurse has assessed and resolved the problem with the mask. It's essential to troubleshoot the equipment first.

The correct answers are choices A, C, and E.

Choice A rationale:

A Venturi mask is designed to deliver a precise concentration of oxygen and is often used in COPD, where it is important not to over-oxygenate the patient. It allows for the adjustment of oxygen concentration by changing the color-coded entrainment adapters.

Choice B rationale:

A non-rebreather mask is not typically used for clients who require a precise concentration of oxygen because it is designed to deliver high concentrations of oxygen, but without a way to precisely control the amount.

Choice C rationale:

An aerosol mask can be used with a nebulizer system to deliver specific concentrations of oxygen along with medication, which is beneficial for COPD patients who may need bronchodilators or steroids in addition to oxygen therapy.

Choice D rationale:

A simple face mask is not suitable for delivering a precise concentration of oxygen as it does not allow for the fine control needed for COPD patients. It is generally used for short-term oxygen therapy and for patients who require a moderate amount of oxygen.

Choice E rationale:

A tracheostomy collar can provide a specific concentration of oxygen when used with a tracheostomized patient and is suitable for long-term use in COPD patients who have a tracheostomy.

In summary, for a client with COPD who requires a precise concentration of oxygen, the Venturi mask, aerosol mask, and tracheostomy collar are appropriate choices as they allow for the delivery of a specific and controlled amount of oxygen.
