(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 C
Explanation
Choice A rationale:
Nasal cannula delivers oxygen through two small prongs placed in the patient's nostrils. While it is a commonly used and well-tolerated device, the FiO2 delivered can vary significantly depending on the patient's breathing pattern and respiratory rate. Thus, it does not provide the most precise and consistent FiO2.
Choice B rationale:
Simple face masks cover the nose and mouth and can provide higher FiO2 levels compared to nasal cannulas. However, the FiO2 delivered still depends on the patient's breathing pattern and the mask's fit, making it less precise and consistent than other options.
Choice C rationale:
Venturi masks are designed to deliver a specific and accurate FiO2, regardless of the patient's breathing pattern. These masks have adjustable ports to control the mix of air and oxygen, providing precise oxygen concentrations.
Choice D rationale:
Non-rebreather masks have one-way valves and a reservoir bag to deliver higher concentrations of oxygen. Although they can provide high FiO2 levels, the delivered concentration can vary based on the patient's breathing pattern and the mask's fit.
Correct Answer is A
Explanation
A humidifier.
Choice A rationale:
A humidifier is necessary to prevent complications in a patient receiving oxygen therapy via a tracheostomy collar. Oxygen delivered through a tracheostomy can dry out the airways and cause discomfort and potential complications. Adding humidity helps maintain airway moisture and prevents drying of the mucous membranes, reducing the risk of mucus plugs and irritation.
Choice B rationale:
A water seal is not necessary for a patient receiving oxygen therapy via a tracheostomy collar. Water seals are used in chest drainage systems to prevent air from entering the pleural space, but they are not relevant in this scenario.
Choice C rationale:
A suction catheter is used to clear secretions from the airway but is not directly related to preventing complications with oxygen therapy via a tracheostomy collar.
Choice D rationale:
A chest tube is not needed for a patient receiving oxygen therapy via a tracheostomy collar. Chest tubes are inserted to drain fluid or air from the pleural space, which is not applicable to this situation.
