What is essential when assessing a client using a nasal cannula?

When using a nasal cannula for oxygen therapy, monitoring for skin breakdown around the nose is essential because prolonged contact can lead to pressure sores or irritation. The nasal cannula's prongs rest on the skin, and if not properly positioned or if left in place for extended periods, they can rub against the skin, causing damage. Recognizing the signs of skin breakdown allows for timely intervention, such as repositioning the cannula, using padding, or switching to a different oxygen delivery method if necessary. This aspect of care ensures that the patient remains comfortable throughout the treatment and minimizes the risk of complications related to skin integrity.

In contrast, ensuring the client lies flat may not be necessary or beneficial for all patients depending on their condition. Providing oxygen without a physician's order goes against protocol and could lead to unsafe practices. Avoiding reassessment during treatment can overlook changes in the patient's condition that might occur, which is critical for adjusting oxygen delivery as needed to meet the patient's requirements.
