The nurse observes that a client with ascites is dyspneic. Which action should the nurse implement first?

A. Measuring vital signs is essential but does not address the immediate respiratory distress the client is experiencing. B. Assisting the client to a high Fowler's position can significantly improve respiratory effort by allowing for better lung expansion and reducing pressure on the diaphragm. C. While deep breathing exercises can be beneficial, they should be initiated after ensuring the client is in a position that facilitates easier breathing. D. Auscultating breath sounds is necessary for further assessment, but prioritizing the client's comfort through positioning is the immediate action to take.
