What is the definition of Administered Veins?

"Administered veins" is like when a superhero doctor, armed with a syringe and a sidekick who's just a big blood vessel, decides to give a medical injection to a patient. It's a fancy way of saying they're injecting fluids directly into the veins, kinda like how they'd give a magic potion to someone with a headache.

Here's a bit unsettling example sentence: "The shadowy figure in the dark administration of veins whispered to the patient, 'Your blood's on sale tonight!'"
