What should the nurse do after obtaining a sample for ABG?
a. Maintain pressure over the site for 3 to 5 minutes.
b. Check the artery proximal to or above the puncture site.
c. Place the syringe into a plastic bag, and send it to the lab.
d. Apply a cool compress to hematoma formation at the puncture site.
A
Maintain continuous pressure on and proximal to the site for 3 to 5 minutes. Palpate the artery below or distal to the puncture site to determine whether pulse quality has changed, indicating alteration in arterial flow. Place a syringe in a cup of crushed ice. Failure to do this may result in decreased pH, arterial oxygen pressure (PaO2), and oxygen saturation. Apply warm compresses to enhance the absorption of blood.
