82. During a venipuncture, the needle is in the vein and blood flow is established. When the second tube is attached, blood flow stops. Which of the following actions should the phlebotomist take?

Answer: B

Explanation:

Rotate the bevel of the needle.

To restore blood flow during a venipuncture when the second tube is attached and the flow stops, the phlebotomist should rotate the bevel of the needle. This action can help to reposition the needle for optimal blood flow within the vein.

A) Withdraw the needle completely.

Withdrawing the needle completely is not advisable as it would disrupt the procedure and may cause unnecessary discomfort to the patient. Additionally, it would require starting the venipuncture process over again, which is inefficient and could lead to further complications.

B) Rotate the bevel of the needle.

Rotating the bevel of the needle is the appropriate action to take in this situation. This technique can reorient the needle within the vein, potentially allowing for better blood flow into the tube that is attached, thereby resolving the issue without needing to withdraw the needle or restart the procedure.

C) Increase tourniquet pressure.

Increasing tourniquet pressure may not be effective and could lead to complications such as hemoconcentration or discomfort for the patient. The tourniquet is intended to assist with venous engorgement, but once blood flow has stopped, adjusting the tourniquet is unlikely to remedy the situation.

D) Activate a new evacuated tube.

Activating a new evacuated tube while maintaining the same needle position is not a recommended action since it does not address the issue of stopped blood flow. This may lead to a waste of supplies and could result in additional discomfort or complications for the patient.

Conclusion

Rotating the bevel of the needle is the correct response to restore blood flow in this scenario, as it can effectively adjust the needle's position within the vein. Other options either complicate the procedure or fail to directly address the problem. Thus, option B stands out as the most suitable choice in managing the situation effectively.
