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:

The nurse should instruct the patient to avoid smoking or being near open flames while using oxygen. Oxygen supports combustion, and smoking or exposure to flames can lead to a fire hazard.

Choice C rationale:

Checking the position of the oxygen delivery device frequently is important to ensure proper oxygen delivery and avoid any displacement or obstruction that may compromise the therapy's effectiveness.

Choice D rationale:

Instructing the patient to report any signs of hypoxia (low oxygen levels) or hypercarbia (high carbon dioxide levels) to the provider is crucial for early detection of potential complications and appropriate management.

Choice E rationale:

Instructing the patient to adjust the flow rate of oxygen as needed allows them to respond to varying oxygen requirements, especially during activities or changes in their respiratory condition.

Choice B rationale:

Using cotton or wool clothing and bedding is not a recommended instruction for oxygen therapy. Synthetic materials are preferred as they are less likely to catch fire compared to cotton or wool.

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.
