A nurse is preparing to administer oxygen to a client who has heart failure and is having severe difficulty breathing. Which of the following oxygen delivery equipment should the nurse select to provide the highest concentration of oxygen to the client?

A. "This can help prevent nausea." Turning, coughing, and deep breathing exercises are not primarily aimed at preventing nausea. These exercises are designed to maintain lung function and prevent respiratory complications.
B. "This can help prevent pneumonia." Correct. Turning, coughing, and deep breathing exercises are essential postoperative activities that help prevent the development of pneumonia by promoting lung expansion, clearing mucus, and preventing atelectasis.
C. "I should do this every 4 hours." The frequency of turning, coughing, and deep breathing exercises may vary based on individual client needs and surgical procedures. This statement does not demonstrate a specific understanding of the appropriate timing for these exercises.
D. "I should do this to keep my heart from beating too fast." Turning, coughing, and deep breathing exercises are not directly related to heart rate regulation. They are focused on lung expansion and airway clearance.

A. Keep the conversation moving by asking about the client's family: While engaging the client in conversation is important, this statement does not specifically address the client's difficulty in talking about their illness.
B. Let the client know that as their nurse, they are available and willing to listen: Correct. This response demonstrates the nurse's willingness to provide emotional support and active listening. Encouraging the client to express their feelings and concerns about their illness is essential in promoting therapeutic communication.
C. Ask if the client understands what to expect in the advanced stages of the illness: While discussing the client's understanding of their illness is essential, it does not directly address their difficulty in talking to others about it.
D. Ask the client's visitors not to say anything about the advanced disease: This response may hinder communication and restrict the client's opportunity to talk about their feelings and concerns with supportive visitors.
