The nurse observes erythema under the chin of a client receiving oxygen at 2 L/minute per nasal cannula. Which intervention should the nurse implement?

A. Placing padding around the cannula tubing is the appropriate intervention to address the erythema under the chin. This padding can help alleviate pressure and reduce skin irritation caused by the tubing. It's a proactive measure to prevent further discomfort or skin breakdown. B. Decreasing the flow rate to 1 L/minute might not address the issue of pressure-related erythema, and it could compromise the client's oxygenation if not clinically indicated. C. Applying lubricant to the tubing may not effectively reduce pressure or irritation caused by the tubing under the chin. D. Discontinuing the use of the nasal cannula should be reserved for situations where it is medically necessary or if an alternative oxygen delivery method is available.
