In episode 41, where Datu gets bitten, Tanya supposedly places a PICC line in his vein, right there in the torrential rain outside. She was a veterinarian, so that is surprising to begin with, but more, picc lines are placed while using an ultrasound, and requires a decent amount of precision, a scalpel, and just isn't plausible for the situation.A central line placed in the internal or external jugular veins are much more likely to be done in an emergency, or just a simple peripheral IV. As a nurse I have been involved in the placement of picc lines and central lines and ivs, and one of the others would be more appropriate for the situation.
