1. What ECG changes should be monitored in a patient with hypokalemia?

A. Flattened T waves and prominent U waves
B. Elevated ST segments and wide QRS complexes
C. Tall T waves and flattened QRS complexes
D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. What intervention is needed for a patient with a chest tube and an air leak?

A. Tighten the connections of the chest tube system
B. Replace the chest tube
C. Clamp the chest tube
D. Continue to monitor the chest tube

Correct answer: A

Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.

3. 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.

4. What should the nurse do 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, the nurse should tighten the connections of the chest tube system. This action can often resolve an air leak causing the continuous bubbling. Clamping the chest tube or replacing it would not address the underlying issue of an air leak and may lead to complications. Continuing to monitor the chest tube without taking corrective action may result in the deterioration of the patient's condition.

5. What are the common manifestations of compartment syndrome?

A. Unrelieved pain, pallor, pulselessness
B. Redness and swelling
C. Fever and infection
D. Swelling and redness

Correct answer: A

Rationale: The correct manifestations of compartment syndrome are unrelieved pain, pallor, and pulselessness. These symptoms indicate compromised blood flow and neurovascular compromise, necessitating immediate medical intervention. Redness and swelling (Choice B) are more commonly associated with inflammation or infection rather than compartment syndrome. Fever and infection (Choice C) are not typical manifestations of compartment syndrome. Swelling and redness (Choice D) are general signs that can be seen in various conditions and are not specific to compartment syndrome.
