What is represented by the abbreviation "PM"?

The abbreviation "PM" is most commonly understood to represent "afternoon" in various contexts, particularly in scheduling and timekeeping. It designates the time period from noon (12:00 PM) until midnight (11:59 PM), making it a fundamental concept in both everyday life and professional environments, including healthcare. Understanding this helps caregivers schedule appointments, medications, and activities effectively throughout the day.

In contrast, the other options have specific meanings in other contexts but are less widely recognized as the primary interpretation of "PM." While "Physical Medicine" and "Periodic Monitoring" might be valid terms in medical or caregiving contexts, they are not the standard usage of "PM." "Post Meal" also has its significance, particularly in dietary monitoring or medication timing, but it does not encompass the broader and more common definition attributed to "PM."
