Florida State Paramedic Practice Exam

What is the correct procedure to take when noticing catheter shear during an IV start?

1. Increase the flow rate and monitor

2. Lift arm, aspirate, remove and start over

3. Apply pressure and continue

4. Change the IV solution immediately

The correct answer is: Lift arm, aspirate, remove and start over

Recognizing catheter shear during an IV start is critical because it indicates that the catheter may not have been inserted properly and could lead to complications such as infiltration or damage to the vessel. The appropriate procedure when you notice catheter shear is to lift the arm, aspirate, remove the catheter, and start over. This action is essential to ensure patient safety and effective treatment. Lifting the arm can help visualize the catheter position and ensure it hasn't punctured the vein or caused any injury. Aspirating allows you to check for blood return, which confirms whether the catheter is still in the vein. If there is no blood return, or if the catheter appears sheared, removal is necessary to prevent any potential complications. Starting over with a new IV site ensures that you are providing the best care possible and reduces the risk of further issues down the line. Other options like increasing the flow rate, applying pressure, or changing the IV solution do not address the root cause of the catheter shear and could potentially exacerbate the situation or lead to complications that may harm the patient. Therefore, the chosen procedure is the most effective and safest response to managing catheter shear.
