Narrative from staff: during initial assessment at first care time, rn examined the patient's piv site in right hand.There was an unusual amount of blood backing up into the tpn tubing, rn flushed it with about 1.5ml ns and there was no problem with the site, however the diluted blood was really backing up into the tubing and filter.I notified the charge nurse and planned to change the filter extension at the end of the tpn tubing.After examining it together they found there was a crack in the filter and tpn was leaking out there.The blanket than had just been changed was wet.Rn next notified nnp and nnp agreed with changing out the iv tubing and extension filter, which was obtained from pharmacy.It was changed without incident and there is no longer any blood backing up into the tubing.
