equal changes in the input give rise to equal changes in the output. Arithmetic sequences have this same special property: equal changes in the input (e.g., moving from term to term). give rise to equal changes in the output (determined by the common difference). Thus, arithmetic sequences always graph as points along a line. The graph of the sequence [beautiful math coming... please be patient] $\,4\,$, $\,7\,$, $\,10\,$, $\,13\,$, $\,\ldots\,$ is the set of points (âdotsâ) shown below.
distal port (16-gauge lumen): The largest lumen; used for central venous pressure monitoring or high volume or viscous fluids, colloids, medications. medial port (18-gauge lumen): Used for parenteral nutrition, medications. proximal (18-gauge lumen): Used for blood sampling, medications, blood component administration.
For example, drawing blood from small-gauge PICC lines (2 or 3 French) can be difficult. Although sources vary, the Infusion Nurses Society recommends using the distal port of a multi-lumen catheter for blood sampling. The distal port is largest (16-gauge) and has a greater flow rate.
