1. What is the appropriate electrical intervention for a patient with ventricular tachycardia and a pulse?

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

Correct answer: B

Rationale: Synchronized cardioversion is the correct electrical intervention for a patient with ventricular tachycardia and a pulse. This procedure delivers a synchronized electrical shock to the heart during a specific phase of the cardiac cycle, aiming to restore the heart's normal rhythm. Defibrillation (choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (choice C) is typically used for bradycardias or certain types of heart blocks. Medication administration (choice D) may be used in some cases, but in the scenario of ventricular tachycardia with a pulse, synchronized cardioversion is the preferred intervention.

2. What intervention is needed for continuous bubbling in the chest tube water seal chamber?

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

Correct answer: A

Rationale: The correct intervention for continuous bubbling in the chest tube water seal chamber is to tighten the connections of the chest tube system. Continuous bubbling indicates an air leak in the system, and tightening the connections can help resolve this issue. Clamping the chest tube (Choice B) is not appropriate and can lead to complications by obstructing the drainage system. Similarly, replacing the entire chest tube system (Choice C) may not be necessary if the issue can be resolved by tightening the connections. Continuing to monitor the chest tube (Choice D) without taking action to address the continuous bubbling may delay necessary interventions to prevent complications.

3. What is an escharotomy, and why is it performed?

• A. To relieve pressure and improve circulation in burn injuries
• B. To reduce pain in the affected area
• C. To remove necrotic tissue from a wound
• D. To remove fluid from a burn wound

Correct answer: A

Rationale: An escharotomy is a surgical procedure performed to relieve pressure and improve circulation in areas affected by deep burns. Choice A is the correct answer because the primary goal of an escharotomy is to prevent compartment syndrome caused by increased pressure within the affected tissues. Choices B, C, and D are incorrect because an escharotomy is not primarily performed to reduce pain, remove necrotic tissue, or drain fluid from a burn wound, but to address the specific issue of compromised blood flow and pressure within deep burn injuries.

4. 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.

5. What is the correct action when a patient reports cramping during enema administration?

• A. Lower the height of the solution container
• B. Increase the flow of the enema solution
• C. Stop the procedure and remove the tubing
• D. Continue the enema at a slower rate

Correct answer: A

Rationale: The correct action to take when a patient reports cramping during enema administration is to lower the height of the solution container. Lowering the height reduces the pressure and speed of the solution entering the rectum, alleviating cramping. Increasing the flow of the enema solution (Choice B) can worsen the discomfort. Stopping the procedure and removing the tubing (Choice C) is not necessary unless there are severe complications. Continuing the enema at a slower rate (Choice D) may not effectively address the immediate cramping issue and could still cause discomfort to the patient.
