What is the maximum infusion rate for potassium via a peripheral line in hypokalemia treatment?

  1. 5 mEq/hr

  2. 10 mEq/hr

  3. 20 mEq/hr

  4. 25 mEq/hr

The correct answer is: 10 mEq/hr

The maximum infusion rate for potassium via a peripheral line in hypokalemia treatment is 10 mEq/hr. This is considered the safe and recommended rate to avoid potential adverse effects. Option A, 5 mEq/hr, may be too slow and not provide enough of a boost in levels. Option C, 20 mEq/hr, and D, 25 mEq/hr, may risk causing hyperkalemia and other complications. Therefore, option B, with a gradual and manageable infusion rate of 10 mEq/hr, is the best option for hypokalemia treatment via a peripheral line.
