Understanding the Nursing Assistant's Scope of Practice
Working with a resident who is receiving intravenous (IV) therapy requires a clear understanding of your professional boundaries as a Certified Nursing Assistant (CNA). The most important principle is that a CNA's role is to monitor and report, not to manage or administer the IV therapy directly. Any intervention, from adjusting flow rates to changing bags, is the responsibility of a licensed nurse (RN or LPN).
Core Monitoring and Reporting Duties
Your observational skills are a vital part of the care team's effort to ensure patient safety. Regular monitoring helps licensed nurses detect potential complications early, which is especially important for seniors who may be more susceptible to adverse reactions. As a CNA, your specific monitoring duties include the following:
- Checking the IV Insertion Site: Observe the site for signs of swelling, redness, warmth, or pain. The area should look normal and feel comfortable to the resident. You should report any changes immediately.
- Observing for Complications: Look for signs of infiltration (IV fluid leaking into surrounding tissue, causing coolness and swelling) or phlebitis (inflammation of the vein, causing warmth, redness, and pain).
- Monitoring the Infusion Flow: Periodically check the fluid drip chamber to ensure the fluid is dripping and the IV pump is running correctly. If the pump alarm sounds, or if the flow has stopped, notify the nurse immediately.
- Listening to Resident Complaints: Take any resident feedback seriously. If they mention pain, itching, or discomfort at the IV site, report it to the nurse. Also, be aware of systemic changes like shortness of breath or edema, which could indicate fluid overload, a risk for older adults.
- Protecting the IV Tubing: When assisting a resident with activities of daily living, be careful not to pull on, kink, or dislodge the IV line. Ensure the tubing is not caught or obstructed by the bed or the resident's position.
What a CNA Cannot Do with IV Therapy
To ensure patient safety and stay within your legal scope of practice, it is crucial to understand and adhere to the tasks that are strictly off-limits for CNAs. These are always the responsibility of a licensed nurse. A CNA must not perform any of the following actions:
- Administer Medications or Fluids: You cannot hang a new IV bag, administer any medication through the IV line, or add anything to an existing IV solution.
- Adjust the Flow Rate: Never manually adjust the clamp on the IV tubing or change the settings on an IV pump. Only a licensed nurse can control the rate of infusion.
- Insert or Remove an IV Catheter: This is an invasive procedure requiring advanced training and is exclusively performed by licensed nurses or other qualified medical personnel.
- Flush an IV Line: Flushing the line with saline or heparin is a skilled nursing procedure used to maintain patency and is not within the CNA's scope.
- Change IV Tubing or Dressings: All changes to the IV administration set and the sterile dressing covering the insertion site are performed by a licensed nurse.
Comparison of IV Therapy Roles
To clarify the division of labor, this table compares the responsibilities of a CNA versus a Licensed Nurse regarding IV therapy.
| Responsibility | Certified Nursing Assistant (CNA) | Licensed Nurse (LPN/RN) |
|---|---|---|
| Initiate IV Therapy | No | Yes |
| Monitor Insertion Site | Yes (and report) | Yes (and intervene) |
| Adjust Flow Rate/Pump | No | Yes |
| Hang IV Bags/Solutions | No | Yes |
| Flush IV Line | No | Yes |
| Change Tubing/Dressings | No | Yes |
| Report Changes to Condition | Yes (crucial) | Yes (part of assessment) |
| Ensure Resident Comfort | Yes | Yes |
The Critical Role of Observation
For residents, particularly the elderly, receiving IV therapy, your diligent observation is the first line of defense against potential complications. Many residents may not be able to articulate discomfort or may be confused. Your role in visually assessing the site and being attentive to subtle changes in their overall condition provides the nursing team with critical information. Your timely reporting allows for prompt intervention, which can prevent more serious issues like localized infection or systemic problems.

Conclusion: The CNA as the First Line of Defense
The nursing assistant's role in IV therapy is defined by observation, communication, and resident comfort. By meticulously monitoring the IV site and the resident's condition, and by immediately reporting any abnormalities to the licensed nurse, you play an indispensable role in maintaining patient safety. Never underestimate the importance of your role as the constant eyes and ears for the nursing team. Adhering strictly to your scope of practice not only protects the resident but also upholds your professional integrity and the standards of care.
