Mr. Smith, diagnosed with pneumonia, was in the hospital for several days and required multiple blood collections throughout the day. He was also receiving antibiotics by IV. After many venipunctures, it was very difficult to find a good vein that was not covered by hematomas. A PICC line was placed for blood collection and medication infusion. The doctor ordered an activated partial thromboplastin time (APTT), complete blood count (CBC), and basic metabolic panel (BMP) every 4 hours. 1. What must the nurse do before collecting the specimen? 2. How many and what size syringes are needed? 3. How will the blood be placed in the collection tubes? 4. What is the correct order of fill?
