Which of the following shows the correct conversion of 0530 to regular time?

  1. 12:30 a.m.

  2. 12:30 p.m.

  3. 5:30 a.m.

  4. 5:30 p.m.

The correct answer is: 5:30 a.m.

To convert military time to regular time, you start by recognizing the format of military time. In this case, 0530 means it's 5 hours and 30 minutes after midnight. Since military time operates on a 24-hour clock system, times from 0000 to 1159 represent hours from midnight to just before noon. When converting 0530, you take the first two digits "05," which corresponds to 5:00 a.m. in standard time. The last two digits, "30," add 30 minutes to that time. Therefore, combining these, 0530 translates to 5:30 a.m. This understanding is crucial when dealing with time conversions, especially in healthcare settings where accurate communication of time is vital for patient care and medication administration.
