Which does the nurse implement after obtaining an arterial blood gases specimen?

1
1 and 3. The nurse maintains pressure over the puncture site for 3-5 minutes while placing the specimen on ice and promptly sending the specimen to the laboratory. If the specimen is allowed to remain at room temperature, the blood can degrade and skew the results; however, the nurse cannot release pressure on the puncture site to accomplish the task.
2. The nurse checks the artery below the puncture site to evaluate distal perfusion from the same artery.
4. If a hematoma forms, the nurse applies a warm compress to increase blood flow and facilitate blood removal. The nurse applies prolonged pressure to the puncture site to avoid hematoma formation because it increases the risk of vessel occlusion and client discomfort and dissatisfaction.
