The nurse notices the client's nares have become dry after receiving 4 liters of oxygen via nasal cannula. What is an appropriate intervention?

A. Ensure that the device is positioned and attached appropriately: Proper positioning of a nasal cannula is important to maintain consistent oxygen delivery and prevent pressure sores, but it does not address the underlying cause of nasal dryness caused by the high flow of oxygen. This intervention alone is insufficient to relieve mucosal irritation. B. Use a cotton tip swab to apply petroleum to the nares: Applying petroleum-based products inside the nares is contraindicated because petroleum is flammable and poses a serious fire risk when oxygen is in use. It also does not provide adequate hydration to nasal mucosa. C. Switch the oxygen delivery device to a simple face mask: Switching to a face mask may alter oxygen delivery and does not necessarily resolve dryness. Higher flow rates through any non-humidified device can still dry the nasal passages, this may not effectively address the problem. D. Consult with respiratory therapy about adding humidification: Adding humidification to supplemental oxygen is the most appropriate intervention for dry nares. Humidified oxygen prevents mucosal dryness, irritation, and discomfort while maintaining adequate oxygenation, particularly at flows of 4 liters per minute or higher.
