A nurse is reviewing the arterial blood gas (ABG) result for a client diagnosed with progressive chronic obstructive pulmonary disease (COPD). The nurse should expect which of the following ABG findings for a client diagnosed with progressive COPD?
pH 7.55, PaCO2 30 mm Hg, PaO2 80 mm Hg, HCO3 24 mEq/L
pH 7.30, PaCO2 60 mm Hg, PaO2 70 mm Hg, HCO3 30 mEq/L
pH 7.40, PaCO2 40 mm Hg, PaO2 94 mm Hg, HCO3 22 mEq/L
pH 7.38, PaCO2 45 mm Hg, PaO2 88 mm Hg, HCO3 26 mEq/L
The Correct Answer is B
A. pH 7.55, PaCO2 30 mm Hg, PaO2 80 mm Hg, HCO3 24 mEq/L: This ABG finding indicates respiratory alkalosis, as evidenced by the elevated pH and decreased PaCO2. In progressive COPD, clients typically retain carbon dioxide rather than blow it off, so this finding would not be expected in a patient with chronic respiratory issues.
B. pH 7.30, PaCO2 60 mm Hg, PaO2 70 mm Hg, HCO3 30 mEq/L: This is the most consistent finding for a client with progressive COPD. The low pH indicates acidosis, and the elevated PaCO2 suggests respiratory acidosis due to carbon dioxide retention, a common problem in COPD. The elevated HCO3 indicates a compensatory metabolic response, as the body attempts to retain bicarbonate to buffer the acidosis.
C. pH 7.40, PaCO2 40 mm Hg, PaO2 94 mm Hg, HCO3 22 mEq/L: These values indicate a normal ABG, which would not be expected in a client with progressive COPD. Patients with chronic lung disease typically present with acid-base imbalances due to respiratory failure, so this finding suggests the client is not exhibiting the expected complications of COPD.
D. pH 7.38, PaCO2 45 mm Hg, PaO2 88 mm Hg, HCO3 26 mEq/L: Although these findings show mild acidosis, the PaCO2 is within normal limits, indicating that this patient may not be experiencing significant respiratory failure. In advanced COPD, one would expect to see a higher PaCO2 and more pronounced acidosis, making this option less characteristic of a patient with progressive COPD compared to option B.

Correct Answer is ["A","C","D","E"]
Explanation
A. Evaluate outcomes at the end of the shift: This is an important recommendation as it allows nurses to assess the effectiveness of interventions and the overall condition of patients. Evaluating outcomes helps in identifying areas for improvement, ensuring that patient care meets safety and quality standards. This practice fosters accountability and continuous improvement in patient-centered care.
B. Evaluate outcomes at the start of the shift: While evaluating outcomes at the beginning of the shift can provide valuable information, it is more effective to evaluate outcomes after care has been provided. Starting the shift with a review of previous outcomes can guide care planning, but the actual evaluation of interventions should occur after implementation to assess their effectiveness.
C. Plan and report outcomes: Planning and reporting outcomes are essential components of providing safe, quality, patient-centered care. This involves setting clear goals for patient care and documenting the expected results, which allows for effective communication among the healthcare team and ensures that everyone is aligned in their approach to patient care.
D. Communicate the plan: Effective communication of the care plan is critical to patient safety and quality care. Sharing the plan with all team members ensures that everyone is aware of the goals and interventions, facilitating collaboration and reducing the risk of errors. Clear communication enhances the patient's understanding of their care and promotes involvement in the decision-making process.
E. Think critically: Critical thinking is fundamental to nursing practice and promotes safe, quality, patient-centered care. It involves analyzing information, evaluating evidence, and making informed decisions based on patient needs and circumstances. Encouraging critical thinking enables nurses to assess situations thoroughly, anticipate potential problems, and implement appropriate interventions.
Correct Answer is D
Explanation
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.
