Intraosseous entry is listed as which of the following main entry points for parenteral moderate sedation?

• A. Gastrointestinal tract
• B. Topical
• C. Intraosseous
• D. Subcutaneous

Answer: (C)

The main idea here is recognizing that intraosseous entry is a parenteral route used for delivering sedation medications directly into the vascular system when IV access is not readily available. Intraosseous delivery involves placing a needle into the bone marrow (often the tibia or humerus) so drugs quickly enter central circulation. This provides rapid onset similar to IV access, making it a valid main entry point for parenteral moderate sedation, especially in difficult-to-access cases. By contrast, gastrointestinal tract entry is enteral (not parenteral) and topical administration is typically local, not systemic. Subcutaneous is another parenteral route, but it represents a different access point than intraosseous.
