PO Meaning in Nursing
Starting out medical abbreviations and terminologies used to confuse me. You might be in the same boat. Let me tell you it does get better with time. Part of that is because abbreviations are commonplace in healthcare to speed up repetitive orders.
Now that you understand what PO means, let me give you some examples.
Example of PO Orders
Here are some prescription PO order examples of how you might see these orders written.
- Colace 100mg PO qhs
- Aspirin 81mg PO daily
- Acetaminophen 325mg PO q8h PRN for pain
- Metformin 500mg PO Daily
So in the case of the orders, this is how you would read them.
- Give 100mg of the medication Colace by mouth at bedtime.
- Would read give the medication aspiring 81mg by mouth daily.
- Would read you can give 325mg of acetaminophen by mouth every 8 hours as needed for pain.
- Give 500mg of the drug Metformin by mouth daily.
