Ketamine can be administered by which routes?

• A. Intramuscular only
• B. Intravenous only
• C. Intramuscular, oral, and intravenous
• D. Subcutaneous only

Answer: (C)

Ketamine can be given through several routes, reflecting its versatility in anesthesia and sedation. Intravenous administration provides the fastest, most controllable onset, making it ideal for rapid induction and precise dosing during procedures. When IV access isn’t available, intramuscular administration is reliable and has a somewhat slower onset, but it remains a common, practical option in emergency or field settings. Oral administration is also possible, but it has low and highly variable bioavailability because of first-pass metabolism, leading to a slower and less predictable effect; it’s rarely used for rapid induction but can be used in specific, resource-limited situations. Because ketamine can be safely and effectively delivered via multiple routes, the choice that lists intramuscular, oral, and intravenous captures the main clinically relevant options. Subcutaneous use exists in some contexts but is not the sole or primary route considered in standard practice.
