2. As part of a written standard protocol for the unit, a nurse adds that irrigation of an occluded cannula is not recommended. What is the rationale against performing this procedure?

a.	It may damage a venous valve.
b.	It may introduce an air embolus into the line.
c.	It may cause the patient pain.
d.	It may force blood clots into the main bloodstream.

 

 

ANS:  D

A cannula may be occluded because a clot has formed against the end of the shaft. By irrigating it, the clot is forced into the bloodstream.
