Nursing Elites

1. A nurse is caring for a client who has a pneumothorax and is being treated with a chest tube. Which of the following findings indicates that the lung has re-expanded?

• A. There is no fluctuation in the water seal chamber.
• B. There is continuous bubbling in the suction control chamber.
• C. There is tidaling in the water seal chamber.
• D. The drainage system is positioned at the level of the client's chest.

Correct answer: A

Rationale: The correct answer is A: 'There is no fluctuation in the water seal chamber.' In a client with a pneumothorax being treated with a chest tube, the absence of fluctuation in the water seal chamber indicates that the lung has re-expanded. This finding suggests that there is no air leak from the lung into the pleural space. Choices B and C are incorrect because continuous bubbling in the suction control chamber or tidaling in the water seal chamber would suggest ongoing air leakage, indicating that the lung has not fully re-expanded. Choice D is also incorrect as the position of the drainage system does not directly indicate lung re-expansion.

2. A client with type 2 diabetes mellitus is scheduled for an arteriogram. Which of the following medications should the nurse instruct the client to discontinue 48 hours prior to the procedure?

• A. Atorvastatin
• B. Digoxin
• C. Nifedipine
• D. Metformin

Correct answer: D

Rationale: The correct answer is D, Metformin. Metformin should be discontinued 48 hours before an arteriogram due to the risk of lactic acidosis. Atorvastatin (Choice A) is a statin used to lower cholesterol levels and is not typically contraindicated before an arteriogram. Digoxin (Choice B) is a medication used for heart conditions and does not need to be discontinued before an arteriogram. Nifedipine (Choice C) is a calcium channel blocker used to treat high blood pressure and angina, and it is not necessary to discontinue before the procedure.

3. A nurse is assessing a client who has a chest tube and notes continuous bubbling in the water seal chamber. Which of the following actions should the nurse take?

• A. Continue to monitor the client.
• B. Clamp the chest tube.
• C. Replace the drainage system.
• D. Apply a dressing over the insertion site.

Correct answer: D

Rationale: The correct action for the nurse to take when continuous bubbling is noted in the water seal chamber of a chest tube is to apply a dressing over the insertion site. Continuous bubbling indicates an air leak, and applying a dressing helps manage this issue by providing a seal. Clamping the chest tube or replacing the drainage system is not appropriate in this situation as it can lead to complications such as tension pneumothorax or inadequate drainage of the pleural space.

4. Which medication is commonly prescribed for patients with atrial fibrillation?

• A. Warfarin
• B. Digoxin
• C. Aspirin
• D. Lisinopril

Correct answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

5. Which lab value is critical to monitor in patients receiving warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.
