Nursing Elites

1. 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.

2. What is the first intervention for a patient admitted with unstable angina?

• A. Administer nitroglycerin
• B. Obtain cardiac enzymes
• C. Start IV fluids
• D. Monitor for chest pain

Correct answer: A

Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

3. 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.

4. What ECG changes are seen in hypokalemia?

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

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

5. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

• A. Defibrillation
• B. Synchronized cardioversion
• C. Pacing
• D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.
