awesome, that's what I thought too-that you can just aspirate...thank u!
Actually this is not always true - many times you can not aspirate. Most peripheral lines should not be drawn from after the first insertion, almost all the rest should not be drawn from after 24 hours. (Of course there will be times you will break this rule, but for most times it stands).
The line is primed when the IV is first inserted (either right away or after a blood draw) and should always be primed. At times it may not be due to someone not clamping the line. In that case you can try to aspirate to pull the air back but if it doesn't work you might need to push the air in. That little air will do nothing other than cause a little pain to the person (sometimes they won't even feel it).
You should always flush first, give the med, then pulsatile flush (kind of a jerky flushing) and clamp the line as you flush - this help insure it is clear throughout.
I always try to assess the line by flushing during assessment, although in many facilities it can be a part of the med order - flush peripheral iv q8hrs and prn. Also watch those on strict fluid precautions (very rare - except for NICU) because even a little bit in a flush (10mls) adds up fast if you are doing it every assessment and every med and every 8 hrs.
Hope this helps.
