An arterial blood gas test is ordered for a client who is admitted due to severe left-sided chest pain that radiated down the left arm. After the specimen is collected, which of the following is the most appropriate nursing action?
  1. Elevate the arm
  2. Apply direct pressure to the site
  3. Observe the site for hematoma
  4. Apply an ice compress to the site
Explanation
Answer: B - Direct pressure is applied to the site for 5 minutes after the needle is used to prevent bleeding and hematoma. Hematoma is a common complication of ABG sampling, which usually occurs when insufficient pressure is applied after the arterial puncture. Elevating the arm and applying ice compresses are not necessary.
