1. What are the early signs of hypokalemia on an ECG?

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

2. What does continuous bubbling in the water seal chamber of a chest tube indicate?

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This signifies that air is escaping from the patient's pleural space into the chest tube system rather than being evacuated properly. An air leak can lead to lung collapse or pneumothorax and requires immediate attention. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because continuous bubbling does not indicate normal chest tube function, drainage in the chest tube, or a blocked chest tube.

3. A nurse is providing teaching to a client who was newly diagnosed with nephrotic syndrome. Which of the following statements should indicate to the nurse that the client understands the teaching?

Correct answer: A

Rationale: The correct answer is A. Nephrotic syndrome leads to edema, especially of the face and dependent areas, due to the loss of protein in the urine. Choice B is incorrect because nephrotic syndrome leads to protein loss in the urine, not an increase in blood protein levels. Choice C is incorrect as stomach pain and gas are not typical symptoms of nephrotic syndrome. Choice D is incorrect as using a soft bristle toothbrush is not directly related to the manifestations of nephrotic syndrome.

4. What are the expected ECG findings in hypokalemia?

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.

5. What is the priority intervention when continuous bubbling is observed in the water seal chamber of a chest tube?

Correct answer: A

Rationale: The correct answer is to 'Check for an air leak.' Continuous bubbling in the water seal chamber of a chest tube indicates an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Checking for an air leak is crucial to prevent respiratory complications. Choice B is incorrect because continuous bubbling is not normal and requires immediate intervention to address the air leak. Choice C is incorrect as replacing the entire chest tube system is not the initial priority when an air leak is suspected. Choice D is incorrect because tightening tube connections may not address the underlying issue of an air leak and should not be the initial action taken in this situation.
