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.

Explanation

A. The nurse applies a tourniquet to assess a vein: Applying a tourniquet is standard practice and does not increase infection risk if proper technique is used.

C. The nurse blows on the area cleansed with alcohol to dry it quickly: Blowing on the site introduces bacteria from the nurse's breath to the cleansed area, increasing the risk of infection.

A. Increased bowel sounds B. Reports of fatigue C. Positive Trousseau's sign D. Reports of numbness in the feet

Correct Answer is B

B. Reports of fatigue: Fatigue is a hallmark symptom of hypokalemia due to impaired cellular and muscle function.

C. Positive Trousseau's sign: This is associated with hypocalcemia, not hypokalemia.

D. Reports of numbness in the feet: This is more commonly linked with neuropathy or hypocalcemia, not hypokalemia.
