Which abbreviation indicates administration by sublingual route?

• A. sl
• B. PO
• C. PRN
• D. QID

Answer: (A)

Recognizing how a medicine is given through its abbreviation is the key idea here. Sublingual administration means the drug is placed under the tongue to be absorbed quickly through the rich blood vessels there. The abbreviation that signals this route is sl. It tells you to administer the medication under the tongue and let it dissolve rather than swallowing it. Compare this with the others: PO means by mouth, which involves swallowing and typically slower absorption with first-pass metabolism. PRN means as needed, a dosing instruction rather than a route. QID means four times a day, indicating frequency rather than how the drug is taken. For sublingual meds, you usually don’t swallow until the tablet is fully dissolved, to achieve the rapid onset intended.
