Which statement about IV Sedation onset is true?

• A. It has a delayed onset.
• B. It has immediate onset.
• C. It has onset only after injection.
• D. It has onset after days.

Answer: (B)

IV administration delivers the drug directly into the bloodstream, so the sedative effect appears almost immediately as it reaches the brain. This rapid onset is a defining feature of IV sedation, typically occurring within seconds to a couple of minutes, depending on the agent used. Since the drug doesn’t need to be absorbed from the gut or pass through the liver first, there’s no delayed onset. Saying the effect starts only after injection or after days doesn’t fit IV use, where the onset is immediate.
