Which problem may arise from difficulty drawing blood from a PICC line?

• A. Increased risk of infection
• B. Clogging and obstruction
• C. Abnormal blood pressure
• D. Excessive fluid leakage

Answer: (B)

Difficulty in drawing blood from a PICC line can often indicate clogging and obstruction within the catheter or the accessing device. When blood cannot be drawn easily, it frequently signals that the lumen of the catheter may be partially or completely blocked. This can occur due to several reasons, including blood clot formation, medication precipitates, or debris accumulation. Such obstructions can hinder the proper flow of fluids and medication, limit effective blood sampling, and even lead to further complications if not addressed. Recognizing this issue is critical, as prolonged clogs can lead to more severe problems, such as catheter malfunction or the need for replacement. It is essential to take appropriate steps to clear the obstruction, often using techniques such as flushing with saline or employing mechanical devices designed for unclogging. This highlights the importance of careful monitoring and maintenance of the PICC line to ensure its efficacy and longevity. In contrast to other options, while infection risks, blood pressure variations, and fluid leakage can be concerns associated with CVAD usage and complications, they are not directly tied to the specific issue of drawing blood difficulty as a first indicator of the status of the catheter.
