Triple lumen central lines/test question/and flushing

Nurses General Nursing

Published

We had an "On the Spot" quiz at work yesterday. Something new the nurse manager has created. She brings out quizzes a couple of times a month ....and we fill in the blanks...on the spot.

Central Line questions:

Which lumen for infusing blood?

" " " " tpn/lipids?

" " " iv solutions.....d5/ns ?

' " " withdrawing blood for blood draws?

And what to use for flushing the ports? how much? do you use ns or heparinized solution.....

She was referring to a sub-clavian, triple lumen,central line i.v.

All hospitals are not the same on this.

Oddly enough.

What do you do at your hospital?

Specializes in tele, stepdown/PCU, med/surg.
Want to be sure to use distal for feedings so it has time to dilute out in the blood before it hits the heart.

How will using the distal for feedings dilute it? I thought it would just take longer to get to the bloodstream.
