A Licensed Practical Nurse (LPN) provides direct patient care under the direction of a Registered Nurse (RN) or physician. A Peripherally Inserted Central Catheter (PICC) line is a thin tube inserted into a peripheral vein, usually in the arm, with its tip resting in a large central vein near the heart. Drawing blood from this central line is a specialized procedure. Whether an LPN can perform this action depends on clinical risk, state regulations, and facility-specific rules.
Understanding PICC Lines and Associated Risks
Drawing blood from a PICC line differs significantly from standard peripheral venipuncture because the catheter provides direct access to the central circulation. Since the tip rests near the heart, any contamination introduced at the hub is a direct threat to the bloodstream. This proximity heightens the risk of Central Line-Associated Bloodstream Infection (CLABSI), a serious and potentially fatal complication.
The procedure requires meticulous sterile technique to prevent microbial entry. Improper technique can also lead to catheter damage, such as rupture, or cause the line to clot (occlusion). The blood drawing process must follow a precise protocol, including discarding an initial 5 to 10 milliliters of blood to clear residual intravenous fluids that could dilute the sample. Strict adherence to flushing protocols is necessary to maintain the catheter’s patency and function.
State Board of Nursing Regulations and LPN Scope
The authority for an LPN to draw blood from a PICC line is determined by the Nurse Practice Act (NPA) in the state where the nurse is licensed. Because nursing regulation is state-dependent, there is no uniform rule across the United States. Some states, like Florida, allow LPNs to access PICC lines for blood drawing after completing a board-approved intravenous (IV) therapy course that includes specific instruction on central lines.
Other states, including Nevada, permit properly trained and IV certified LPNs to perform phlebotomy from a PICC line, provided they follow established clinical practice guidelines. Conversely, some State Boards of Nursing prohibit LPNs from accessing any central venous access device, including PICC lines, for any purpose. This restriction often occurs in settings like long-term care, where the activity may be reserved exclusively for Registered Nurses due to the required assessment and judgment.
The legal standard focuses on the complexity of the task and the LPN’s demonstrated competency. Many states require LPNs performing this function to operate under the direction and supervision of an RN or authorized healthcare provider. Due to this wide variation, a procedure acceptable in one state may violate the scope of practice in another. Therefore, an LPN must consult their specific state’s Board of Nursing advisory opinions before performing the procedure.
Institutional Policy and Required Competency
Even if a State Board of Nursing (BON) permits an LPN to draw blood from a PICC line, the individual healthcare facility has the final say through its internal policies. Institutional policies often impose stricter limits than the state’s minimum legal requirement, usually for liability or standardization purposes. For instance, a facility may reserve all central line access procedures for Registered Nurses to standardize care and minimize risk.
Facilities that allow LPNs to perform this task mandate a rigorous process of specialized training and competency validation to ensure patient safety. This involves completing a formal, facility-specific training course on central line care and blood sampling. Following the training, the LPN must demonstrate proficiency in the skill to a Registered Nurse. This validation confirms the LPN’s ability to perform the procedure accurately and safely, including recognizing and responding to potential complications like infection or occlusion.
Roles of Alternative Staff for Central Line Access
When an LPN is legally or institutionally restricted from drawing blood from a PICC line, the task defaults to other qualified personnel. The Registered Nurse (RN) is typically the primary staff member responsible for all aspects of central venous access device management, including routine blood draws. RNs possess a broader scope of practice that includes the comprehensive patient assessment necessary for managing potential central line complications.
In larger facilities, specialized teams often manage these high-risk procedures to ensure adherence to best practices. These teams, such as IV teams or vascular access nurses, are experts in placing, maintaining, and accessing all types of central lines. Utilizing specialized staff for PICC line blood draws helps minimize hub manipulation and infection risk, supporting the facility’s overall infection control efforts. If the LPN cannot perform the draw, the RN or a member of the specialized team ensures the patient receives the necessary laboratory testing without compromising the integrity of the PICC line.
