The abbreviation po indicates which route?

The abbreviation po indicates which route?

• A. By Mouth
• B. Before meals
• C. After meals
• D. With meals

Answer: (B)

The key idea is understanding drug administration abbreviations and what they describe. po stands for per os, which is Latin for “by mouth.” It tells you the route the medication is given—swallowed and absorbed through the gastrointestinal tract. Timing instructions exist too, but they are separate: ac means ante cibum (before meals) and pc means post cibum (after meals). These timing abbreviations don’t define the route. So po indicates By Mouth.
