What is the primary reason medications aren't injected into arteries?

Question

Quizplus · Accepted Answer

Injecting medications directly into arteries can lead to a high concentration of the drug being delivered to a localized area, potentially causing toxicity or damage to the tissues. Unlike veins, where the slower blood flow allows for a more gradual distribution and dilution of the medication, arterial blood flow is much faster and under higher pressure, leading to rapid distribution of a concentrated dose of medication to a specific area, which can be harmful.
