Medication given p.o. is administered which way?

• A. By Injection
• B. Rectally
• C. Topically
• D. Orally

Answer: (D)

p.o. stands for per os, meaning the medication is taken by mouth and swallowed. This route involves the drug entering the digestive tract, where it is absorbed, often with possible variation due to food and first-pass liver metabolism. That’s why oral administration is described as by mouth or orally. Other routes correspond to different terms: injection (parenteral, delivered through a needle), rectally (through the rectum), and topically (applied to the skin). So the option that matches p.o. is the one indicating oral administration.
