What are the responsibilities of a nurse in IV therapy?

According to the Infusion Nurses Society, proper IV therapy management is crucial for patient safety. Understanding what are the responsibilities of a nurse in IV therapy? is essential for both aspiring and current healthcare professionals to ensure the highest standards of care.

Quick Summary

The responsibilities of a nurse in IV therapy encompass thorough patient assessment, sterile IV insertion and maintenance, precise fluid and medication administration, continuous monitoring for adverse reactions, and prioritizing patient education and safety throughout the entire process.

Key Points

• Initial Assessment: A nurse first assesses the patient's condition, verifies orders, and selects the appropriate IV site before therapy begins.

• IV Insertion & Administration: Nurses are responsible for skillfully inserting IV lines, preparing solutions, and accurately administering fluids or medications.

• Ongoing Monitoring: Continuous monitoring for complications like infiltration, phlebitis, or infection is a critical and constant responsibility.

• Patient Education: Explaining the procedure, potential side effects, and warning signs to the patient is an essential part of the nurse's role.

• Documentation & Record-Keeping: Thoroughly documenting all aspects of IV therapy is crucial for legal and safety purposes.

• Infection Control: Adhering to strict sterile technique and proper site care is a primary responsibility to prevent infection.

• Collaboration: Infusion nurses work closely with physicians, pharmacists, and other healthcare team members to manage patient care.

The Foundational Role of the Infusion Nurse

At its core, intravenous (IV) therapy is a critical medical procedure used to deliver fluids, medications, and nutrients directly into a patient's bloodstream. The infusion nurse, a specialized Registered Nurse (RN), is the cornerstone of this process, ensuring it is performed safely and effectively. This role demands a high level of technical proficiency, critical thinking, and compassionate patient interaction. The infusion nurse's duties extend far beyond simply starting an IV line; they are responsible for the entire therapeutic process, from initial assessment to discontinuing therapy and beyond.

Phase 1: Pre-Infusion Responsibilities

Before a single drop of fluid is administered, a nurse has a series of vital tasks to complete to ensure patient safety.

Verifying Orders and Patient Rights

Every IV therapy procedure starts with a physician's order. The nurse's first responsibility is to verify this order, ensuring its accuracy and appropriateness for the patient's condition. This includes applying the 'six rights' of medication administration:

1. Right Patient: Confirming the patient's identity using at least two identifiers, such as name and date of birth.
2. Right Drug: Verifying the specific medication or fluid to be administered.
3. Right Dose: Double-checking the dosage calculation.
4. Right Route: Confirming the IV route of administration.
5. Right Time: Ensuring the medication is given at the correct interval.
6. Right Documentation: Preparing to accurately record the procedure afterward.

Patient Assessment and Preparation

A comprehensive assessment is necessary to determine the most suitable IV access and to anticipate any potential complications. This involves assessing the patient's overall hydration status, reviewing lab results, and evaluating potential IV sites. The nurse must also educate the patient about the procedure, what to expect, and any potential side effects, addressing any fears or anxiety they may have. This initial interaction is crucial for building trust and ensuring the patient's comfort throughout the process.

Phase 2: IV Access and Administration

Once all preparations are complete, the nurse proceeds with the hands-on aspect of IV therapy.

Initiating IV Access

This requires sterile technique and a steady hand. The nurse must select the correct device for the prescribed therapy, which could be a simple peripheral IV or a more complex central venous catheter depending on the patient's needs.

Steps for initiating a peripheral IV:

1. Gather all necessary supplies, including the IV catheter, tubing, fluids, and dressing.
2. Perform hand hygiene and don sterile gloves.
3. Apply a tourniquet and select a suitable vein, often in the hand or forearm.
4. Cleanse the site thoroughly with an antiseptic agent and allow it to dry completely.
5. Insert the catheter into the vein, observing for flashback, and then advance and secure it.
6. Dispose of sharps properly and attach the IV tubing.

Preparing and Administering Infusions

After securing access, the nurse must prepare the infusion. This includes priming the tubing to remove all air, verifying compatibility of combined medications, and setting the correct flow rate on the IV pump or by manually calculating drip rate.

Phase 3: Continuous Monitoring and Maintenance

The nurse's responsibility does not end once the infusion begins. Ongoing vigilance is necessary to ensure the therapy is proceeding safely.

Monitoring for Complications

The nurse must regularly check on the patient and the IV site to identify any issues early. Key complications to monitor for include:

• Infiltration/Extravasation: Fluid leaking into the surrounding tissue, causing swelling or pain.
• Phlebitis: Inflammation of the vein, characterized by redness and tenderness along the vein.
• Infection: Signs like warmth, redness, and pus at the insertion site.
• Fluid Overload: Especially in elderly or pediatric patients, monitoring for symptoms like crackles in the lungs or swelling is essential.
• Allergic Reactions: Watching for signs of a sudden adverse reaction to the medication.

Site and Tubing Management

Regularly changing IV site dressings and tubing according to facility policy is crucial for infection control. The nurse also troubleshoots equipment malfunctions, such as occlusions or pump alarms, ensuring uninterrupted therapy.

A Comparison of IV Access Types

Feature	Peripheral IV	Central Line/PICC
Insertion Site	Small veins in extremities (arms, hands)	Larger, more central veins (neck, chest, arm via PICC)
Duration	Short-term therapy (days)	Long-term therapy (weeks to months)
Medication Type	Non-irritating fluids, short-term medications	Irritating medications (chemo), high-volume fluids, TPN
Nurse Responsibility	Standard venipuncture skills, daily site assessment	Advanced training required, complex dressing changes, meticulous infection control
Risk Profile	Lower risk of systemic infection	Higher risk of systemic infection due to central placement

Patient Education: A Critical Component

Beyond the technical tasks, the nurse is a primary educator. This involves teaching the patient and their family about how to care for the IV site, recognizing signs of complications, and understanding the purpose of the therapy. For home infusions, this teaching is especially vital for the patient's safety and successful treatment outcome. The Infusion Nurses Society, for example, offers resources to support this educational role Infusion Nurses Society.
