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

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

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This occurs when air is entering the system from the outside, preventing the lung from fully re-expanding. Choice B is incorrect because continuous bubbling is not a sign of normal chest tube function. Choice C is incorrect because a blocked chest tube would typically exhibit no bubbling or fluctuation in the water seal chamber. Choice D is incorrect as continuous drainage would not cause bubbling in the water seal chamber.

2. What are the signs and symptoms of compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized redness and swelling
C. Fever and infection
D. Loss of sensation in the affected area

Correct answer: A

Rationale: The signs and symptoms of compartment syndrome include unrelieved pain, pallor, and pulselessness. Unrelieved pain is a key characteristic, indicating tissue ischemia due to increased pressure within a closed anatomic space. Pallor results from compromised blood flow, and pulselessness indicates severe ischemia requiring immediate intervention. Choices B, C, and D are incorrect because localized redness and swelling, fever and infection, and loss of sensation are not specific signs of compartment syndrome. Therefore, the correct answer is A.

3. What are the expected ECG findings in hypokalemia?

A. Flattened T waves
B. Prominent U waves
C. Elevated ST segments
D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

4. What ECG changes are seen with hyperkalemia?

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

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

5. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the nurse identify as a possible complication of TPN administration?

A. Pitting edema of bilateral lower extremities
B. Hypoactive bowel sounds in all four quadrants
C. Weight is the same as the day before
D. Bilateral posterior lung sounds are diminished

Correct answer: A

Rationale: The correct answer is A: Pitting edema of bilateral lower extremities. Pitting edema can indicate fluid overload, which is a potential complication of TPN administration. Choice B, hypoactive bowel sounds, is more indicative of a gastrointestinal issue rather than a complication of TPN. Choice C, weight remaining the same, is expected to remain stable with proper TPN administration. Choice D, diminished lung sounds, is not directly related to TPN administration and is more suggestive of a respiratory issue.
