The nurse assesses a client who has a nasal cannula delivering oxygen at 2 liters/minute. To assess for skin damage related to the cannula, which areas should the nurse observe? Select all that apply.

A. Around the nostrils is a common area for skin damage when using a nasal cannula. The constant pressure and friction from the cannula tubing can cause irritation or breakdown around the nostrils. B. Bridge of the nose is another area to assess for skin damage. The nasal cannula can cause pressure ulcers or redness on the bridge of the nose, especially if the cannula is not properly positioned or if the client wears it for prolonged periods. C. Across the forehead is not typically an area affected by a nasal cannula. The cannula does not usually make contact with the forehead, so skin damage in this area is unlikely. D. Over the cheeks is an important area to assess. The tubing of the nasal cannula can rub against the skin on the cheeks, causing irritation or breakdown, particularly if the tubing is too tight or not positioned correctly. E. Tops of the ears should also be observed. The tubing of the nasal cannula can cause pressure on the ears, especially if the tubing is looped behind the ears, leading to irritation or skin breakdown.
