Which electrolytes in OTC products require a warning if they exceed a certain threshold?

Na, K, Mg
Na, K, Mg, Ca
Na, K
K, Mg, Ca

The correct answer is: Na, K, Mg, Ca

OTC products are over-the-counter products that can be purchased without a prescription. Electrolytes are important minerals that help regulate the balance of fluids in the body. When electrolytes are present in high quantities, they can cause harm to the body. Therefore, product labels must include a warning if certain electrolytes are present above a certain threshold. Option A is incorrect because it only includes three electrolytes (Na, K, and Mg) when the question specifically asks for the electrolytes that require a warning if they exceed a certain threshold. Option B is the correct answer because it includes all four electrolytes (Na, K, Mg, and Ca) that are required to have a warning if they exceed a certain threshold. Option C is incorrect because it only includes two electrolytes (Na and K), and option D is incorrect because it includes three electrolytes (K, Mg, and Ca) but does not include Na which is required to have a warning if it exceeds a certain threshold. Therefore, option B is the most accurate and complete answer.
