What is a common reason for drawing blood from a central line?

• A. To ensure faster healing
• B. To reduce complications of venipuncture external to the vein
• C. To save time during blood draws
• D. To improve patient comfort

Answer: (B)

Drawing blood from a central line significantly reduces the complications associated with traditional venipuncture, such as the risk of hematomas, phlebitis, or infections. Central lines are often placed in larger veins that can accommodate frequent blood draws without causing damage or discomfort to smaller peripheral veins. By utilizing a central line, healthcare providers can minimize the need for multiple needle sticks, which can lead to complications and discomfort for the patient. This makes it a preferable option in patients requiring extensive or frequent blood sampling, especially in clinical settings where access to veins may be challenging. Other options may have some merit in particular contexts, but the primary benefit of using a central line for blood draws centers around the reduction of complications directly associated with venipuncture.
