1. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. Drainage in the chest tube
• C. A blocked chest tube
• D. Normal chest tube function

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This signifies that air is escaping from the patient's pleural space into the chest tube system rather than being evacuated properly. An air leak can lead to lung collapse or pneumothorax and requires immediate attention. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because continuous bubbling does not indicate normal chest tube function, drainage in the chest tube, or a blocked chest tube.

2. After a healthcare provider misreads a glucose level and administers insulin, what is the priority intervention?

• A. Monitor for hypoglycemia
• B. Administer glucose IV
• C. Document the incident
• D. Monitor for hyperglycemia

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Administering insulin based on a misread glucose level can lead to hypoglycemia. Monitoring for hypoglycemia is crucial as it is a potential adverse effect of the insulin administration. Administering glucose IV (Choice B) is not the priority as there is no indication of hypoglycemia yet. Documenting the incident (Choice C) is important but not the immediate priority over patient safety. Monitoring for hyperglycemia (Choice D) is not the priority after administering insulin in response to a misread glucose level.

3. What dietary recommendation should be given to a patient with pre-dialysis end-stage kidney disease?

• A. Limit phosphorus intake to 700 mg/day
• B. Increase sodium intake
• C. Restrict protein intake to 0.55-0.60 g/kg/day
• D. Eat three large meals per day

Correct answer: A

Rationale: The correct dietary recommendation for a patient with pre-dialysis end-stage kidney disease is to limit phosphorus intake to 700 mg/day. Excess phosphorus can be harmful to individuals with kidney disease as their kidneys are not able to remove it effectively. Choice B is incorrect as increasing sodium intake is generally not recommended for individuals with kidney disease due to its association with high blood pressure. Choice C is also incorrect as protein restriction is a common recommendation for patients with advanced kidney disease, but the range provided is not accurate. Choice D is incorrect as eating three large meals per day may not be suitable for managing the condition.

4. What is the initial nursing action for a patient with a chest tube found to have an air leak?

• A. Check the tube connections
• B. Replace the chest tube
• C. Remove and reinsert the chest tube
• D. Document the incident

Correct answer: A

Rationale: When a patient with a chest tube is found to have an air leak, the priority action for the nurse is to check the tube connections. This step helps identify the source of the air leak, which can be caused by loose or disconnected tube connections. Once the source of the leak is identified and addressed, further interventions may be necessary. Replacing or removing and reinserting the chest tube should not be the initial response unless there are specific indications for these actions. Documenting the incident is important but comes after addressing the immediate concern of the air leak.

5. What ECG changes are seen with hyperkalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.
