What is the most common side effect of diuretics such as furosemide (Lasix)?

  • A. Hypokalemia.
  • B. Hyperkalemia.
  • C. Hypernatremia.
  • D. Hyponatremia.
Correct Answer: A

Rationale: The correct answer is 'Hypokalemia.' Diuretics like furosemide increase the excretion of potassium, leading to hypokalemia as a common side effect. Hyperkalemia (choice B) is the opposite condition characterized by high potassium levels, which is not typically associated with furosemide use. Hypernatremia (choice C) is increased sodium levels, while hyponatremia (choice D) is decreased sodium levels, neither of which are the most common side effects of furosemide. Therefore, choice A is the best answer.
