A nurse is caring for a client who has hypoxemia and is receiving oxygen therapy via nasal cannula at 4 L/min. The nurse should monitor the client for which of the following complications of oxygen therapy?
Oxygen toxicity.
Carbon dioxide retention.
Nasal dryness.
Fire hazard.
The Correct Answer is A
Choice A rationale:
At a flow rate of 4 L/min, oxygen therapy through a nasal cannula can increase the risk of oxygen toxicity, especially if used for prolonged periods. Oxygen toxicity can cause damage to the lungs and other organs.
Choice B rationale:
Carbon dioxide retention is not a common complication at this flow rate. It may occur in patients with severe chronic obstructive pulmonary disease (COPD) at higher oxygen flow rates.
Choice C rationale:
Nasal dryness is a common but relatively minor complication of oxygen therapy via nasal cannula. It can cause discomfort but is not a severe concern.
Choice D rationale:
Fire hazard is not directly related to the use of a nasal cannula but rather to the use of oxygen in the presence of flammable materials or near open flames. It is a concern for all oxygen delivery devices, not specific to nasal cannulas.

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","C","E"]
Explanation
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.
