(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 D
Explanation
Choice A rationale:
Monitoring the patient's respiratory rate, depth, rhythm, and effort is crucial for assessing the effectiveness of oxygen therapy and ensuring proper oxygenation through the tracheostomy collar.
Choice B rationale:
Educating the patient on how to use and care for the tracheostomy collar is essential to ensure the patient's safety and compliance with the therapy.
Choice C rationale:
Implementing safety measures to prevent fire hazards from the oxygen source is crucial, especially when oxygen is delivered via tracheostomy collar, which may have increased oxygen flow rates.
Choice D rationale:
This is the correct choice. All the provided interventions (monitoring respiratory parameters, patient education, and safety measures) are essential components of the plan of care for a patient with a tracheostomy who requires oxygen therapy.
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.
