Which statement about parenteral medications is correct?

• A. Parenteral medications are absorbed more quickly than enteral medications.
• B. Tylenol is an example of a parenteral medication because it is taken orally.
• C. Compared to enteral medications, parenteral medications have fewer side effects.
• D. Parenteral medications are absorbed by the digestive system.

Answer: (A)

Parenteral medications are given by routes outside the digestive tract (such as IV, IM, or subcutaneous injections). Because they bypass the GI system and, in many cases, first-pass metabolism, they enter the bloodstream more quickly than most enteral (often oral) medications. IV administration can be essentially immediate, while IM and subcutaneous routes generally provide faster absorption than swallowing a pill that must be dissolved and absorbed through the intestinal lining. That is why this option correctly states that parenteral medications are absorbed more quickly than enteral medications. The other statements don’t fit. An oral Tylenol pill is not parenteral, even though there is an injectable form of acetaminophen; the route determines whether something is parenteral. Parenteral meds do not inherently have fewer side effects—their safety profile depends on the drug and route, and injections can cause local reactions. Finally, parenteral meds are not absorbed by the digestive system by definition.
