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

• A. An air leak
• B. A blocked chest tube
• C. Normal chest tube function
• D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak in the system. This occurs when air is entering the system through a leak, preventing the lung from fully re-expanding. Choice B, a blocked chest tube, is incorrect as a blocked tube would result in a lack of drainage rather than continuous bubbling. Choice C, normal chest tube function, is incorrect as continuous bubbling signifies an issue. Choice D, continuous drainage from the chest tube, is incorrect as bubbling in the water seal chamber specifically indicates an air leak, not just the presence of drainage.

2. What is the first nursing action for a patient admitted with chest pain from acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's urine output
• C. Administer IV fluids
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This is the priority action for a patient admitted with chest pain from acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improve blood flow to the heart, and relieve chest pain. Checking the patient's urine output (Choice B) is not the priority in this situation. Administering IV fluids (Choice C) may not be necessary unless indicated by the patient's condition. Obtaining cardiac enzymes (Choice D) is important but is not the initial action needed to address the patient's acute symptoms.

3. How does hyponatremia place the patient at risk?

• A. Seizures
• B. Fatigue
• C. Cardiac dysrhythmias
• D. Muscle weakness

Correct answer: C

Rationale: Hyponatremia places the patient at risk for cardiac dysrhythmias. While hyponatremia can lead to seizures due to cerebral edema caused by fluid imbalance, the most immediate and life-threatening risk is cardiac dysrhythmias. Low sodium levels can disrupt the heart's electrical activity, potentially leading to fatal arrhythmias. Although fatigue and muscle weakness are symptoms of hyponatremia, cardiac dysrhythmias pose the most critical concern as they can have severe consequences.

4. 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.

5. What is the expected finding in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized swelling and redness
• C. Numbness and tingling
• D. Fever and infection

Correct answer: A

Rationale: In a patient with compartment syndrome, the expected finding includes unrelieved pain, pallor, and pulselessness. These are classic signs of compartment syndrome and indicate compromised blood flow and tissue perfusion, necessitating urgent intervention. Choices B, C, and D are incorrect because localized swelling and redness, numbness and tingling, as well as fever and infection, are not typical findings associated with compartment syndrome.
