Q1 Fluid and Electrolyte Imbalances / Acid-Base（水電解質・酸塩基）
Which ECG change is characteristic of hyperkalemia?
- Flattened T waves
- Prominent U waves
- Tall, peaked T waves
- Prolonged QT interval with a normal T wave
Show the answer and explanation
Answer: C. Tall, peaked T waves are characteristic of hyperkalemia. High potassium changes how heart cells recover, and severe levels can cause dangerous dysrhythmias.

Q2 Fluid and Electrolyte Imbalances / Acid-Base（水電解質・酸塩基）
How is 0.45% sodium chloride classified?
- Isotonic
- Hypotonic
- Hypertonic
- Colloid
Show the answer and explanation
Answer: B. 0.45% sodium chloride is hypotonic. It has a lower solute concentration than plasma, so water moves from the blood into cells.
