1. What intervention is required when continuous bubbling is seen 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
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, tightening the connections of the chest tube system is the appropriate intervention. This action can often resolve an air leak, which is the common cause of continuous bubbling. Clamping the chest tube or replacing it is not recommended as the first-line intervention because it may lead to complications or unnecessary tube changes. Continuing to monitor the chest tube without addressing the air leak would delay necessary corrective action, potentially causing respiratory compromise in the patient. Therefore, tightening the connections of the chest tube system is the most suitable initial step to manage continuous bubbling in the water seal chamber.

2. 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.

3. A nurse is reviewing the medical record of a client who has unstable angina. Which of the following findings should the nurse report to the provider?

• A. Breath sounds
• B. Temperature
• C. Blood pressure
• D. Creatine kinase

Correct answer: A

Rationale: The correct answer is A: Breath sounds. When caring for a client with unstable angina, changes in breath sounds could indicate left ventricular failure and pulmonary edema due to decreased cardiac output and reduced cardiac perfusion. Reporting any abnormalities in breath sounds promptly to the provider is crucial to prevent further complications. Choices B, C, and D are not directly related to the immediate management of unstable angina. Temperature, blood pressure, and creatine kinase levels are important parameters to monitor but are not the priority in this situation.

4. What teaching should be provided to a patient following an escharotomy for burn injuries?

• A. Monitor for infection
• B. Restrict fluid intake
• C. Avoid physical activity
• D. Limit phosphorus to 1,500 mg/day

Correct answer: A

Rationale: Following an escharotomy for burn injuries, patients should be taught to monitor for infection and care for the incision site. Choice A is the correct answer because infection is a common risk after a procedure involving incisions. Choices B, C, and D are incorrect. Restricting fluid intake is not typically advised after an escharotomy; avoiding physical activity may vary depending on the individual's condition and should be guided by healthcare providers; and limiting phosphorus to 1,500 mg/day is not directly related to post-escharotomy care.

5. What ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.
