Final answer:
The priority nursing action when discontinuing a left radial arterial line is to prevent complications by applying pressure to the site for hemostasis, continuously monitoring for signs of bleeding or poor perfusion, and documenting the procedure and patient's response.
Step-by-step explanation:
When discontinuing a patient's arterial line, the priority nursing action is to ensure the safety and prevention of complications such as bleeding or hematoma formation at the site of the arterial line. Following proper protocol, the nurse should apply pressure to the site after the line is removed to prevent hemorrhage. This can be done by using a sterile gauze pad and applying firm pressure for at least 5 to 10 minutes, or until hemostasis is achieved.
It is essential to monitor the site continuously for signs of bleeding, swelling, or discoloration, which could indicate a hematoma or infection. Additionally, the extremity should be observed for adequate perfusion by checking the color, temperature, capillary refill, and pulse distal to the site of the arterial line. Following the procedure, the patient's vital signs should be monitored closely, and any abnormalities should be reported to the physician immediately.
Lastly, proper documentation of the procedure and the patient's response is crucial for continuity of care. The importance of these steps aligns with the idea of using a checklist to ensure that all necessary precautions are taken, such as those proposed by Dr. Pronovost for central venous line insertion. This practice of effective communication and teamwork in medical procedures, sometimes called a time out, ensures patient safety and quality care.
