(Select all that apply): A client with a tracheostomy is being weaned from mechanical ventilation. Which of the following oxygen delivery devices can be used for this client?
Venturi mask.
Tracheostomy collar.
T-piece.
Aerosol mask.
Mechanical ventilator.
Correct Answer : B,C,E
Choice A rationale: A Venturi mask is designed for nasal and oral use, providing specific oxygen concentrations. It cannot be properly secured or deliver effective oxygenation directly to a tracheostomy site.
Choice B rationale: A tracheostomy collar fits over the tracheostomy tube to deliver humidified oxygen. It is a primary device used during weaning to provide supplemental oxygen while allowing spontaneous breathing.
Choice C rationale: A T-piece or T-bar connects directly to the tracheostomy tube. It allows for high-flow humidified oxygen delivery and is frequently used to assess a client's readiness to breathe independently.
Choice D rationale: An aerosol mask is shaped to fit over the nose and mouth for large-volume nebulization. It is not designed to fit the neck or provide a seal for tracheostomy-specific weaning.
Choice E rationale: A mechanical ventilator is used during the weaning process through specific modes like CPAP or Pressure Support. These modes allow the client to take spontaneous breaths while providing assistance.

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.
Correct Answer is ["A","C","E"]
Explanation
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.
