Nursing Elites

1. A client learns about pursed-lip breathing. Which statement by the client indicates teaching has been effective?

• A. I will breathe in quickly through my mouth and out through my nose.
• B. I will breathe in slowly through my nose and out through pursed lips.
• C. I will hold my breath for 10 seconds before exhaling.
• D. I will breathe in and out through pursed lips.

Correct answer: B

Rationale: The correct technique for pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips. This technique helps improve expiration and reduce air trapping. Breathing in quickly, holding the breath, or breathing in and out through pursed lips does not align with the correct method of pursed-lip breathing.

2. A client is 1 day postoperative following a lobectomy with a chest tube drainage system in place. Which finding by the nurse indicates a need for intervention?

• A. Chest tube eyelets not visible
• B. Continuous bubbling in the suction control chamber
• C. Presence of tidal fluctuation in the water seal chamber
• D. Development of subcutaneous emphysema

Correct answer: D

Rationale: The development of subcutaneous emphysema is a concerning finding that requires immediate intervention. Subcutaneous emphysema results from air leaking into the tissues, which can lead to respiratory compromise. It is important to address this issue promptly to prevent further complications. The other options are normal or expected findings in a chest tube drainage system. Chest tube eyelets not being visible may indicate dislodgement, continuous bubbling in the suction control chamber indicates proper functioning, and the presence of tidal fluctuation in the water seal chamber demonstrates appropriate drainage and lung re-expansion.

3. A client has a disposable three-chamber chest tube in place. Which of the following findings should indicate to the nurse that the client is experiencing a complication?

• A. Continuous bubbling in the water-seal chamber
• B. Occasional bubbling in the water-seal chamber
• C. Constant bubbling in the suction-control chamber
• D. Fluctuations in the fluid level in the water-seal chamber

Correct answer: A

Rationale: Continuous bubbling in the water-seal chamber indicates air is leaking into the pleural space, which is a complication. The water-seal chamber should have intermittent bubbling during normal functioning. Occasional bubbling in the water-seal chamber is normal and shows the system is working as intended. Constant bubbling in the suction-control chamber suggests an issue with the suction control. Fluctuations in the fluid level in the water-seal chamber are an expected finding.

4. A client has a mediastinal chest tube. Which symptom requires the nurse's immediate intervention?

• A. Production of pink sputum
• B. Tracheal deviation
• C. Drainage greater than 70 mL/hr
• D. Sudden onset of shortness of breath

Correct answer: B

Rationale: Immediate intervention is required if the client exhibits tracheal deviation as it could indicate a tension pneumothorax, a life-threatening condition that requires prompt attention to prevent respiratory compromise. Production of pink sputum may indicate bleeding but would not be as immediately life-threatening as tracheal deviation. Drainage greater than 70 mL/hr could indicate hemorrhage, which also requires attention but is not as urgent as tracheal deviation. Sudden onset of shortness of breath could indicate various issues, including dislodgment of the tube or pneumothorax, which require intervention but are not as critical as tracheal deviation in this context.

5. 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.
