By mouth is abbreviated as which term?

• A. p.o.
• B. PO
• C. by mouth
• D. orally

Answer: (A)

Abbreviations for how a drug is taken are a key part of clear pharmacology communication, especially for the oral route. The standard shorthand for by mouth is p.o., from the Latin per os, meaning through the mouth. This compact notation is widely used in prescriptions and care notes to signal oral administration quickly and unambiguously. While uppercase PO appears in some contexts, many guidelines and exam keys favor the lowercase, perioded form p.o. here, which is why it’s the preferred pick. The full words “by mouth” or “orally” are descriptive rather than abbreviations, so they don’t fit the abbreviation-focused notation asked for. The essence is that p.o. accurately and traditionally represents the oral route in a concise, recognized way.
