If a dose is administered every 8 hours for 24 hours, how many doses are given?

Explanation:
When dosing at fixed intervals, figure out how many intervals fit into the total time. For a 24-hour period with an eight-hour interval, doses occur at the start, after eight hours, and after sixteen hours. The next dose would be at twenty-four hours, which falls outside the 24-hour window. So, three doses are given in that span.
