Which blood gas result will the nurse expect to observe in a patient with respiratory alkalosis?

A. Deep breathing exercises should be performed regularly, regardless of the level of pain. The exercises are crucial for preventing lung complications, and pain management should be addressed so that the client can perform these exercises effectively.
B. This statement reflects a proper understanding of the importance of regular deep breathing exercises. Performing these exercises every hour while awake helps to keep the alveoli open and reduces the risk of atelectasis and pneumonia. Consistent practice is essential for maximizing lung expansion and preventing complications.
C. Coughing exercises should be performed regularly, not just when experiencing shortness of breath. Coughing helps to clear secretions from the airways and prevent their accumulation, which can lead to respiratory infections and other complications.
D. Avoiding deep breathing exercises is not advisable. While there may be some discomfort, deep breathing is essential for lung health post-operatively. The exercises help prevent complications such as atelectasis.

A. Lubricating the suction catheter tip with sterile saline is generally not recommended. The catheter tip is usually not lubricated before suctioning. Instead, suctioning should be performed using a dry, sterile catheter to prevent introducing any substances into the airway that could cause irritation or infection.
B. Hyperoxygenating the patient with 100% oxygen before suctioning is a crucial step. This helps to prevent hypoxia during the suctioning procedure, as suctioning can temporarily reduce the oxygen levels in the blood. By providing 100% oxygen for 30 to 60 seconds, the nurse ensures that the patient has an adequate oxygen reserve and reduces the risk of oxygen desaturation during suctioning.
C. Performing chest physiotherapy is not a routine pre-suctioning action and is generally done as part of a separate management strategy for clearing secretions. Chest physiotherapy involves techniques such as percussion, vibration, and postural drainage to help mobilize secretions from the lungs.
D. Instilling normal saline into the airway before suctioning (known as “normal saline lavage”) is not recommended. This practice can actually cause harm, such as increasing the risk of infection, causing bronchospasm, and diluting secretions which may then become more difficult to suction.
