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. A client has a chest tube in place connected to wall suction due to a right-sided pneumothorax. The client complains of chest burning. Which of the following actions should be taken?

• A. Increase the wall suction.
• B. Strip the chest tube.
• C. Clamp the chest tube.
• D. Reposition the client.

Correct answer: D

Rationale: When a client with a chest tube connected to wall suction complains of chest burning, it may indicate that the tube is irritating or compressing nearby tissues. Repositioning the client can help relieve this irritation by ensuring the tube is not kinked or pulling on the tissues. Increasing suction, stripping the tube, or clamping it are not appropriate actions and could potentially worsen the situation or cause harm.

3. While assessing a client with pulmonary tuberculosis, which of the following findings should the nurse expect?

• A. Lethargy
• B. High-grade fever
• C. Weight gain
• D. Dry cough

Correct answer: A

Rationale: When assessing a client with pulmonary tuberculosis, the nurse should expect lethargy as a common finding. Tuberculosis can cause fatigue and weakness due to the body's efforts to fight the infection. High-grade fever is another common symptom of tuberculosis, not weight gain or dry cough. Weight loss is more typical in tuberculosis due to decreased appetite and systemic effects of the infection. A persistent productive cough with sputum is more characteristic of tuberculosis rather than a dry cough.

4. A client is receiving oxygen therapy via nasal cannula. Which finding indicates that the therapy is effective?

• A. The client is able to ambulate in the hall without dyspnea.
• B. The client has a respiratory rate of 24 breaths per minute.
• C. The client's oxygen saturation is 92%.
• D. The client has a productive cough.

Correct answer: A

Rationale: The correct answer is A. Effective oxygen therapy should improve the client's ability to perform activities without dyspnea. This indicates that the oxygen therapy is adequately supporting the client's respiratory needs. An oxygen saturation of 92% may suggest the need for a higher flow rate to improve oxygenation. A respiratory rate of 24 breaths per minute is elevated, indicating potential respiratory distress. A productive cough does not necessarily indicate effective oxygen therapy, as it is a symptom of respiratory irritation or infection, not oxygenation status.

5. A client is scheduled for a colonoscopy and receiving education from a healthcare provider. Which statement by the client indicates a need for further teaching?

• A. I can have clear liquids up to 2 hours before the procedure.
• B. I need to take a laxative the night before the procedure.
• C. I will be sedated during the procedure.
• D. I should avoid eating solid foods for 24 hours before the procedure.

Correct answer: D

Rationale: The correct answer is D because clients are typically instructed to avoid solid foods for 12-24 hours before a colonoscopy, not a full 24 hours. This statement indicates a need for further teaching to ensure the client follows the correct dietary instructions for the procedure.
