Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. While caring for a client using O2 in the hospital, what assessment finding indicates that goals for a priority diagnosis are being met?

• A. 100% of meals being eaten by the client
• B. Intact skin behind the ears
• C. The client understanding the need for oxygen
• D. Unchanged weight for the past 3 days

Correct answer: B

Rationale: When a client is using oxygen, there is a risk for impaired skin integrity due to pressure from tubing. Intact skin behind the ears suggests that the client is not experiencing skin breakdown, meeting the goals for this diagnosis. The client's nutrition, understanding of oxygen therapy, and weight stability are important but do not directly relate to the priority diagnosis of skin integrity in this context.

3. A post-anesthesia care unit nurse is caring for a client who is postoperative following a thoracotomy and lobectomy. Which of the following postoperative assessments should the nurse give the highest priority to?

• A. Arterial blood gases
• B. Urinary output
• C. Chest tube drainage
• D. Pain level

Correct answer: A

Rationale: Arterial blood gases are crucial to assess postoperatively in a client who has undergone thoracotomy and lobectomy to monitor oxygenation and ventilation status. Changes in arterial blood gases can indicate respiratory complications or inadequate gas exchange, which are critical issues that need prompt intervention to prevent further complications. While urinary output, chest tube drainage, and pain level are important assessments, monitoring arterial blood gases takes precedence in this specific postoperative scenario to ensure optimal respiratory function and overall patient well-being.

4. A healthcare professional is assessing a client who is recovering from a lung biopsy. Which assessment finding requires immediate action?

• A. Increased temperature
• B. Absent breath sounds
• C. Productive cough
• D. Incisional discomfort

Correct answer: B

Rationale: Absent breath sounds may indicate a pneumothorax, a serious complication post lung biopsy. This condition requires immediate attention to prevent respiratory distress.

5. A client is planning to perform nasotracheal suction for a client who has COPD and an artificial airway. Which of the following actions should the nurse take?

• A. Perform suctioning for up to four passes.
• B. Apply suction to the catheter when advancing it into the trachea.
• C. Preoxygenate the client with 100% oxygen for up to 3 min.
• D. Limit each suction pass to 25 seconds.

Correct answer: C
