1. An over-the-needle peripheral intravenous catheter assembly, comprising:
a catheter adapter comprising a proximal end, a distal end, and a lumen extending therebetween;
an over-the-needle peripheral intravenous catheter extending from the distal end of the catheter adapter, the over-the-needle peripheral intravenous catheter comprising a proximal end, a tip, and a length of tubing therebetween, wherein the length of tubing comprises at least one position indicator to indicate a position of the over-the-needle peripheral intravenous catheter relative to a vasculature, wherein the at least one position indicator comprises a first pair of markings and a second pair of markings, wherein the first pair of markings is disposed on an outer surface of the length of tubing closer to the tip of the over-the-needle peripheral intravenous catheter than the distal end of the catheter adapter, wherein the second pair of markings is disposed on the outer surface of the length of tubing closer to the distal end of the catheter adapter than the tip of the over-the-needle peripheral intravenous catheter, wherein a first marking and a second marking of the first pair of markings are spaced apart, wherein a first marking and a second marking of the second pair of markings are spaced apart, wherein the first pair of markings provides a reference for depth of insertion of the over-the-needle peripheral intravenous catheter and the second pair of markings provides an indicator of catheter dislodgement by variation in a location of the first marking or the second marking of the second pair of markings with respect to skin of a patient, wherein an unmarked portion of the tubing extends from the first pair of markings to the second pair of markings; and
an introducer needle extending through the length of tubing of the over-the-needle peripheral intravenous catheter and comprising a sharp distal tip configured to introduce the over-the-needle peripheral intravenous catheter into the vasculature, wherein a distance between the first marking and the second marking of the first pair of markings is a lie distance, wherein the lie distance equals a distance between a proximal end of a bevel of the introducer needle and the tip of the over-the-needle peripheral intravenous catheter.
