Question 12

Intradermal injection administers a medication into the skin.

Intradermal injections are specifically designed to deliver medication directly into the dermal layer of the skin. This method is often used for allergy tests or vaccinations.

A) Intraperitoneal

Intraperitoneal injections involve administering medication into the peritoneal cavity, which is not related to the skin. This method is typically used for certain medical treatments and is not suitable for skin administration.

B) Intravenous

Intravenous injections deliver medication directly into the bloodstream through a vein. This method bypasses the skin completely, making it inappropriate for the question regarding skin administration.

C) Intramuscular

Intramuscular injections involve injecting medication into a muscle. While this method is effective for certain types of medications, it does not involve the skin's layers in the same way that intradermal injections do.

D) Intradermal

Intradermal injections are the correct choice as they specifically administer medication into the skin. This technique targets the dermis, allowing for localized treatment or testing.

Conclusion

Intradermal injection is the only option that correctly administers medication into the skin, making it the definitive answer. Other options, such as intraperitoneal, intravenous, and intramuscular, focus on different delivery methods that do not involve the skin, thus failing to meet the criteria of the question.
