(Select all that apply) A nurse is preparing to administer oxygen therapy to a client who has COPD and requires a precise concentration of oxygen. Which of the following devices should the nurse use for this client?
Venturi mask.
Non-rebreather mask.
Aerosol mask.
Simple face mask.
Tracheostomy collar.
Correct Answer : A,C,E
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.

Correct Answer is B
Explanation
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.
