1. What is the priority action when the nurse administers insulin for a misread blood glucose reading?

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

Correct answer: A

Rationale: The priority action when the nurse administers insulin for a misread blood glucose reading is to monitor for signs of hypoglycemia. Insulin administration based on a misread blood glucose could lead to hypoglycemia due to an unnecessary dose. Monitoring for signs of hypoglycemia is crucial for prompt intervention if blood glucose levels drop dangerously low. Option B, monitoring for hyperglycemia, is incorrect in this situation as the concern is over-treatment with insulin causing hypoglycemia. Option C, administering glucose IV, is only necessary if hypoglycemia occurs. Option D, documenting the incident, is important for reporting and learning purposes but is not the immediate priority when the focus is on patient safety and preventing complications.

2. What is the primary nursing action for a patient experiencing continuous bubbling in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Continue monitoring the chest tube
• D. Replace the chest tube system

Correct answer: A

Rationale: The correct answer is to tighten the connections of the chest tube system. Continuous bubbling in the chest tube water seal chamber indicates an air leak. By tightening the connections of the chest tube system, the nurse can often resolve the issue by ensuring there are no loose connections allowing air to enter. Clamping the chest tube or replacing the chest tube system are not appropriate actions in this situation. Clamping the tube can cause a dangerous buildup of pressure, while replacing the system should only be considered if tightening the connections does not resolve the air leak.

3. A client has a right-sided pneumothorax, and a chest tube is inserted. Which finding indicates that the chest drainage system is functioning correctly?

• A. Gentle bubbling in the suction chamber
• B. Crepitus around the insertion site
• C. Constant bubbling in the water seal chamber
• D. Absence of breath sounds on the right side

Correct answer: A

Rationale: In a chest drainage system, gentle bubbling in the suction chamber indicates proper functioning, showing that the system is connected and working effectively to remove air or fluid from the pleural space. Crepitus around the insertion site (Choice B) suggests subcutaneous emphysema, not chest tube functionality. Constant bubbling in the water seal chamber (Choice C) indicates an air leak. Absence of breath sounds on the right side (Choice D) is indicative of the pneumothorax, not the chest tube function.

4. What are the expected symptoms in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized swelling and redness
• C. Fever and swelling
• D. Weakness and fatigue

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. These symptoms are classic signs of compartment syndrome, which is a serious condition characterized by reduced circulation in a closed muscle compartment. The pain is typically severe and disproportionate to the injury, and if left untreated, it can lead to tissue damage and loss of function. Choices B, C, and D are incorrect because they do not represent the hallmark symptoms of compartment syndrome. Localized swelling and redness may be present but are not specific to this condition. Fever and swelling are more indicative of inflammation or infection, while weakness and fatigue are nonspecific and do not typically occur in isolation in compartment syndrome.

5. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.
