Which nursing action should be prioritized for immediate intervention for Patrick?

Starting oxygen via nasal cannula at 4 L/min is prioritized for immediate intervention because it addresses potential respiratory distress. If Patrick is experiencing altered hepatobiliary function, he may also have associated complications such as hypoxia, which can manifest due to reduced oxygenation from liver dysfunction or other related issues.

Administering oxygen helps to ensure that vital organs receive adequate oxygenation, which is crucial for maintaining overall physiological stability. In cases where liver function is compromised, the risk of developing further complications increases, including difficulties in maintaining adequate oxygen levels in the blood. Therefore, providing supplemental oxygen promptly can help mitigate these risks and stabilize Patrick's condition, allowing for further assessment and intervention as required.

The other options, such as administering oral fluids, providing a comfort pack, or encouraging physical activity, may be important, but they do not address immediate life-support needs as directly as ensuring adequate oxygenation does.
