Which of the following complications can occur if a clotted cannula is flushed too aggressively?
The patient can experience speed shock
A clot can be forced into the circulation causing serious complications.
A painful arterial spasm can occur
The catheter can become dislodged and fall out.
The Correct Answer is B
A. The patient can experience speed shock: Speed shock is a rapid infusion of a substance (like a medication or fluid) into the bloodstream, usually occurring when the infusion rate is too fast. This is not typically caused by flushing a clotted cannula.
B. A clot can be forced into the circulation causing serious complications: Flushing a clotted cannula too aggressively can dislodge a clot, causing it to travel into the bloodstream. This can lead to serious complications like embolism or stroke, especially if the clot is large or travels to a vital organ.
C. A painful arterial spasm can occur: While arterial spasms can occur, they are more often related to arterial catheterization or manipulation rather than flushing a venous cannula.
D. The catheter can become dislodged and fall out: While this could potentially happen, it is less of a concern compared to the risk of pushing a clot into circulation, which is a more immediate danger.
