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. During an assessment, an older adult client's son reports that the client has been sick with a respiratory illness for the past 6 days. Which of the following assessment findings is a manifestation of pneumonia in the older adult client?

• A. Bradycardia
• B. Night sweats
• C. Confusion
• D. Narrowed pulse pressure

Correct answer: C

Rationale: Confusion is a common manifestation of pneumonia in older adults. It can result from inadequate oxygenation to the brain due to respiratory compromise. Bradycardia, night sweats, and narrowed pulse pressure are not typically specific findings associated with pneumonia and should be further assessed or monitored, but confusion is a key indicator that warrants immediate attention.

3. A client with chronic obstructive pulmonary disease is being taught by a nurse about ways to facilitate eating. Which of the following statements indicates a need for further teaching?

• A. I will rest for at least 30 minutes before eating.
• B. I will take my bronchodilators after meals.
• C. I will eat five or six small meals each day.
• D. I will choose foods that are not gas-forming.

Correct answer: B

Rationale: Option B, 'I will take my bronchodilators after meals,' indicates a need for further teaching. Bronchodilators should be taken before meals to help open the airways and make breathing easier before eating. This statement suggests a misunderstanding of the timing for optimal bronchodilator effectiveness. Options A, C, and D are all appropriate strategies for facilitating eating for a client with chronic obstructive pulmonary disease.

4. 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.

5. When a client develops an airway obstruction from a foreign body but remains conscious, which of the following actions should the nurse take first?

• A. Insert an oral airway
• B. Administer the abdominal thrust maneuver
• C. Turn the client to the side
• D. Perform a blind finger sweep

Correct answer: B

Rationale: When a client develops an airway obstruction and remains conscious, the nurse's initial action should be to administer the abdominal thrust maneuver. This technique, also known as the Heimlich maneuver, can help dislodge the obstructing object and clear the airway. Inserting an oral airway, turning the client to the side, or performing a blind finger sweep are not recommended as the first interventions for a conscious individual with an airway obstruction.
