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.

Answer and Explanation

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.

Correct Answer is B

Explanation

A. Dextrose 10% in water: Dextrose solutions provide calories but do not restore volume or replace electrolytes. They are not typically used in hypovolemic shock.

B. Lactated Ringer's: Lactated Ringer’s solution is an isotonic solution containing sodium, potassium, calcium, and lactate, which helps restore both fluid volume and electrolytes in the case of hypovolemic shock. It is commonly used while awaiting blood transfusions.

C. 0.33% sodium chloride: This is a hypotonic solution that can cause fluid to shift into cells and is not appropriate for fluid resuscitation in hypovolemia, which requires an isotonic solution.

D. 0.45% sodium chloride: This is a hypotonic solution as well, and it could worsen hypotension by causing fluid shifts into the cells, which is not ideal for treating hypovolemic shock.
