A patient has several blood tests ordered. The nurse determines that the best vein to use for the blood draw is superficial and will correctly initiate the stick at a
1. 45-degree angle.
2. 30-degree angle.
3. 15-degree angle.
4. 5-degree angle.
Question 2
Before drawing the patient's blood, the nurse carefully lines up evacuated tubes in the order in which they will be filled. The nurse collects blood in the correct order because
1. Laboratory draws are time-consuming and collecting blood in the correct order will be a more efficient use of time.
2. The medical technologist in charge of the laboratory has designated the order based on the facility's protocol.
3. Some tubes have additives that have the potential to contaminate each of the remaining tubes to be filled.
4. The collection tube that is filled first has an anticoagulant, which prevents blood from clotting in the remaining tubes to be collected.
