For which electrolytes must OTC labels include a kidney stone disease warning?

  1. K, Mg

  2. Na, K, Mg

  3. K, Mg, Ca

  4. Na, K, Ca

The correct answer is: K, Mg, Ca

OTC (over-the-counter) labels must include a warning for kidney stone disease when the electrolyte levels of potassium (K), magnesium (Mg), and calcium (Ca) are present. Option A (K, Mg) is incorrect because it is missing the calcium (Ca) component. Option B (Na, K, Mg) is also incorrect because although it includes all three electrolytes, it is missing the calcium (Ca) component. Option D (Na, K, Ca) is incorrect because it is missing the magnesium (Mg) component. Therefore, option C (K, Mg, Ca) is the correct answer.
