Which is an advantage of IM administration for GI-irritating drugs?

Explanation:
Bypassing the GI tract is the key idea. Injecting a drug into muscle allows it to enter the systemic circulation without passing through the gastrointestinal mucosa, so drugs that irritate the GI tract can be given intramuscularly to minimize local GI side effects. This route avoids contact with the stomach and intestines, reducing irritation, gastritis, or ulcers that might occur with oral dosing. The other statements misstate how intramuscular administration works: IM can be used for GI-irritating drugs, it does not inherently worsen GI irritation, and it does not require IV co-administration.
