A nurse is caring for a client who has a prescription for a peripheral IV catheter.
After puncturing the skin with the vascular access device and noting a blood return in the flashback chamber, which of the following actions should the nurse perform next?
A.
Flush the catheter with saline
B.
Retract the stylet
C.
Release the tourniquet
D.
Advance the catheter into the vein
The Correct Answer and Explanation is:
The correct answer is D. Advance the catheter into the vein.
Explanation:
When inserting a peripheral IV catheter, the sequence of steps is critical for ensuring successful and safe placement. Here’s a breakdown of the procedure after obtaining a blood return in the flashback chamber:
- Advance the Catheter into the Vein:
- Reasoning: After puncturing the skin and visualizing blood return in the flashback chamber of the catheter, it confirms that the needle is correctly positioned within the vein. The next step is to advance the catheter over the needle into the vein. This step is crucial because it ensures that the catheter itself, rather than just the needle, is placed within the vein, allowing for effective infusion or blood withdrawal.
- Retract the Stylet:
- Reasoning: Once the catheter is properly advanced, the needle or stylet is retracted to leave the catheter in place. However, this action should occur only after the catheter has been advanced into the vein to ensure that the catheter is securely positioned before withdrawing the needle.
- Flush the Catheter with Saline:
- Reasoning: Flushing the catheter with saline is typically done after the catheter is fully advanced and the needle is retracted. This step helps confirm that the catheter is properly positioned and functioning correctly, as it should allow for smooth flow of the saline without resistance. Flushing too early might dislodge the catheter or cause discomfort.
- Release the Tourniquet:
- Reasoning: The tourniquet is usually released after the catheter has been advanced and secured. Releasing the tourniquet too early might make it more challenging to insert the catheter properly because the vein could collapse or move.
In summary, the immediate step following a blood return in the flashback chamber is to advance the catheter into the vein (Option D). This ensures that the catheter is properly positioned within the vein before the needle is retracted, the catheter is flushed, and the tourniquet is released.
