Principles of Health Science

2. Why do you need to know about military time?
We use military time in healthcare in order to tell the difference between AM and PM more easily.
Using military time decreases errors in patient care
If a doctor tells you to give medications at 9:00, 3:00 and 11:00, does he mean AM or PM?
It’s more precise to say that these medications are due at 0900, 1500 and 2300.

3. How do you calculate military time?
You will write military time without the colon between the hours and minutes
Example - Midnight is 2400, 12noon is 1200
If the time is before 10:00 AM, put a zero in front of the time
Ex: 9:00 AM is 0900
No zero is needed for 10:00 and 11:00am and 12:00pm (1000, 1100 and 1200)

4. How do you calculate military time?
After 12:00 noon, you must add “12” to the hour column in the given time
Example: 2:35 pm is 1435
Let’s Practice!!!!!!

6. Convert the following clock times to military time
4:28 PM
2:30 AM
12:00 midnight
10:17 PM
6:30 PM
7:00 AM
11:35 AM

7. Convert the following military times into clock times (AM or PM)
12 noon
0925
1820
0126
1530
1745
2245

8. Lets make it a little more challenging
What about when it is after 12:00 midnight but before 1:00 am?
What would 12:01 am be in military time?
Answer 0001

9. Group Activity
Work with a partner to answer the question about the case study.
Respiratory Therapist Carol has two patients scheduled to get albuterol treatments.
Patient 1 has treatments at 12:30pm, 8:30pm and 4:30am
Patient 2 has treatment at 8:30am, 4:30pm and 12:30am.
RT Carol charts in her notes:
Albuterol treatment given to patient 1 at 4:30am, pt. tol. well, VS stable
Albuterol treatment given to patient 2 at 4:30am, pt. tol well but noted increased HR at the end of treatment. Will monitor HR closely.
What error do you note in RT Carol’s notes? What could potentially happen in medication errors? .

10. Individually Fold a piece of paper as shown
On one side list standard times
On the other list the times in military time
Review your chart
Then you and a partner quiz each other without looking
Once you have completed that…
Create a Sample Schedule for your day using military time
-create one for a school day include (class schedules, meal times, after school activities, at home activities, bedtime etc.)
-create one for a weekend day (include leisure activities, church, meals, bedtimes etc.)
