A medicine that is labeled 'PO' should be given:
A
topically
B
by injection
C
by mouth
D
rectally
Verified step by step guidance1
Step 1: Understand the abbreviation 'PO'. In medical terminology, 'PO' stands for 'per os,' which is Latin for 'by mouth.' This indicates the route of administration for the medicine.
Step 2: Review the options provided in the problem: topically, by injection, by mouth, and rectally. Each option represents a different route of drug administration.
Step 3: Compare the abbreviation 'PO' with the options. Since 'PO' means 'by mouth,' this matches the correct route of administration.
Step 4: Recall that topical administration involves applying medication directly to the skin, injection involves delivering medication via a needle into the body, and rectal administration involves inserting medication into the rectum. These routes do not correspond to 'PO.'
Step 5: Conclude that the correct answer is 'by mouth,' as it aligns with the meaning of 'PO' in medical terminology.
