The practical nurse (PN) is completing a focused assessment on a client who is prescribed oxygen at 3 liters per minute by nasal cannula. Which assessment finding by the PN requires immediate action?

The client is prescribed oxygen at 3 liters per minute, but the flowmeter shows that only 1 liter of oxygen is being delivered. This indicates an inadequate oxygen supply and immediate action is required to adjust the flow rate to meet the prescribed oxygen requirement. Failure to provide the appropriate oxygen flow rate can compromise the client's respiratory status and oxygenation. The PN should promptly increase the flow rate to the prescribed level to ensure the client receives the necessary oxygen therapy. The other assessment findings mentioned are also important to note and address, but they do not require immediate action: A. The client lying in a supine position in bed: While it is generally recommended for clients receiving oxygen therapy to be in an upright or semi-upright position, this finding does not require immediate action unless there are specific indications or contraindications related to the client's condition. B. The cannula pressed snugly against the client's cheeks: The cannula should fit comfortably and securely on the client's face without causing discomfort or pressure areas. While this finding may require adjustment to ensure proper fit and comfort, it does not require immediate action unless it is causing harm or compromising oxygen delivery. D. There is no humidifier attached to the delivery system: While a humidifier may be recommended to add moisture to the oxygen, its absence does not pose an immediate threat to the client's safety or require immediate action. The need for humidification depends on the client's condition and comfort level, and it can be addressed by attaching a humidifier if necessary.
