Which medication is a common example of potassium replacement?

1. Lasix

2. K-Dur or Micro-K

3. Xanax

4. Ativan

The correct answer is: K-Dur or Micro-K

Potassium replacement medications are essential for individuals who may have low potassium levels in their body, a condition known as hypokalemia. K-Dur and Micro-K are specific formulations of potassium chloride, designed to replenish potassium in patients who need it due to various medical conditions or as a side effect of certain diuretics. These medications help maintain proper electrolyte balance, support normal muscle and nerve function, and are often prescribed to prevent complications associated with potassium depletion. Other options mentioned, such as Lasix (a diuretic), Xanax (an anti-anxiety medication), and Ativan (another anti-anxiety medication), have different primary purposes. Lasix is known to help manage fluid retention and blood pressure, sometimes leading to potassium loss; however, it does not serve as a potassium supplement itself. Xanax and Ativan are both medications aimed at treating anxiety, with no direct role in potassium supplementation. Thus, K-Dur and Micro-K stand out as the appropriate choice for potassium replacement therapy.
