A nurse is caring for a client.

Exhibits

Which of the following actions should the nurse take? (Select all that apply.)

A. Increased arterial oxygen: Clients with COPD typically experience chronic hypoxemia due to alveolar destruction, airway inflammation, and mucus production, which impair gas exchange. Rather than increased oxygen levels, they often have a decreased PaO₂, requiring supplemental oxygen therapy. However, excessive oxygen administration can suppress their respiratory drive, worsening CO₂ retention.
B. Increased pH: COPD is associated with respiratory acidosis due to chronic CO₂ retention from inadequate alveolar ventilation. While the kidneys compensate by increasing bicarbonate retention, the pH usually remains low or near normal in chronic cases rather than becoming elevated. A higher pH would indicate alkalosis, which is not typical in COPD unless there is an additional metabolic disturbance.
C. Increased carbon dioxide: COPD causes airway obstruction and reduced alveolar ventilation, leading to CO₂ retention (hypercapnia). As CO₂ accumulates in the blood, it lowers the pH, resulting in respiratory acidosis. Chronic hypercapnia is a hallmark of advanced COPD, and in response, the kidneys retain bicarbonate to partially compensate, stabilizing the pH over time but leaving PaCO₂ elevated.
D. Decreased alveolar function: While COPD does lead to progressive alveolar damage and reduced gas exchange, this is a structural and functional change rather than a specific abnormality seen in arterial blood gases. The primary ABG finding in COPD is hypercapnia, which reflects inadequate ventilation and CO₂ retention rather than just decreased alveolar function alone.

A. Repositioning in bed: While repositioning the client is important for comfort and preventing complications such as pressure ulcers, it is not the top priority immediately after a pneumonectomy. Proper positioning can help improve respiratory function, but ensuring the stability and function of chest drainage systems takes precedence in the immediate postoperative period.
B. Use of the incentive spirometer: Encouraging the use of an incentive spirometer is crucial for promoting lung expansion and preventing atelectasis. However, it is essential first to ensure that the client’s chest tube is functioning properly and that there are no complications from the surgery. While this intervention is important, it follows the need to assess the chest tube.
C. Application of antiembolism stockings: While applying antiembolism stockings is a good practice to prevent venous thromboembolism, it is not the highest priority in the immediate postoperative period. Other assessments and interventions, such as monitoring respiratory status and chest tube function, are more critical in this early stage after surgery.
D. Chest tube and pleura-vac assessment: This is the priority nursing intervention in the immediate postoperative period. After a pneumonectomy, monitoring the chest tube's placement, drainage output, and function is vital for ensuring that the pleural space is adequately drained and that there are no complications such as pneumothorax or hemothorax. This assessment is crucial for maintaining respiratory function and overall stability in the postoperative client.
