If a physician prescribes a medication to be taken every 12 hours, how many times will the medication be taken in a 24-hour period?

When a medication is prescribed to be taken every 12 hours, it indicates that the patient should take the medication twice within a 24-hour period. This is because 24 hours can be divided into two 12-hour intervals. During the first 12 hours, the patient will take the medication once, and then again during the next 12 hours, for a total of two doses. This pattern of administration ensures that the medication remains effective in the system while adhering to the prescribed dosing schedule. Therefore, the correct answer reflects this dosing frequency within the 24-hour timeframe.
