The route that may be more dangerous than others because of the possibility of injecting a drug incorrectly into a vein is which of the following routes?

A) Intradermal route
B) Intramuscular route
C) Intravenous route
D) Anti-tick drugs

C) Intravenous route
The intravenous route may be more dangerous than the others because of the possibility of injecting a drug incorrectly into a vein, causing serious harm or even death. Intravenous medications are absorbed more quickly than oral medications and are irretrievable after being injected. The intradermal and intramuscular routes are not as dangerous because injecting between skin layers or muscles does not involve the same speed of absorption as does intravenous injection. The intrathecal route is not discussed in this capacity in this chapter.
