A nurse is caring for a patient who is receiving oxygen therapy via nasal cannula. The nurse notices that the patient's nares are dry and irritated. What should the nurse do first?

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.

Choice A rationale:

Nasal cannula delivers low to moderate concentrations of oxygen and may not be effective for a client with thick secretions, dry mucous membranes, or upper airway edema. Additionally, the nasal cannula may not provide sufficient humidification to alleviate these conditions.

Choice B rationale:

The simple face mask is not ideal for a client with thick secretions, dry mucous membranes, or upper airway edema as it may not provide enough humidification and could be uncomfortable for the patient.

Choice C rationale:

A partial rebreather mask also may not be the most appropriate choice for this client as it has a reservoir bag that may not adequately humidify the oxygen, leading to discomfort and potential worsening of dry mucous membranes.

Choice D rationale:

The aerosol mask is the most appropriate choice because it delivers humidified oxygen in the form of small aerosol particles, which can help alleviate thick secretions, moisturize dry mucous membranes, and reduce upper airway edema. This mask is beneficial for patients who require higher humidity levels to maintain airway patency and comfort.
