A patient is very restless while receiving IV fluids to treat dehydration. The IV catheter has slipped out of the vein, and fluid is delivered to the surrounding tissues under the skin, causing swelling. Which term best describes this occurrence?

1. A

   Infection

2. B

   Fluid overload

3. C

   Infiltration

4. D

   Extravasation

Explanation

Listen in Hindi

• Infiltration is the correct term for the leakage of non-vesicant (non-tissue-damaging) IV fluid into the surrounding subcutaneous tissue.
• The scenario describes swelling from standard hydration fluids leaking from the vein, which is the classic presentation of infiltration.
• Key signs of infiltration include localized swelling (edema), coolness, and pallor at the IV site, which are caused by the fluid accumulating outside the vein.

Why Other Options Were Wrong

• Option A: Infection would present with signs of inflammation, such as redness, warmth, tenderness, and possibly purulent drainage. The question only mentions swelling.
• Option B: Fluid overload is a systemic complication, not a localized one. Its signs include shortness of breath, crackles in the lungs, and elevated blood pressure.
• Option D: Extravasation is similar to infiltration but specifically involves the leakage of a vesicant—a substance that can cause severe tissue damage or necrosis (e.g., chemotherapy drugs, potassium chloride). Fluids for dehydration are non-vesicant.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Complications of Intravenous (IV) Therapy to guide bedside assessment, documentation, and the next nursing action.
• Frequent assessment of IV sites (e.g., every 1-2 hours for adults) is a critical nursing responsibility to ensure patient safety and prevent complications.
• Early detection and management of infiltration are crucial to prevent pain, compartment syndrome (in severe cases), and the need for restarting the IV line.
• What if? If the fluid being administered was a chemotherapy agent like doxorubicin, the correct term would be extravasation. This is a medical emergency requiring immediate, specific protocols (like aspirating the drug and administering an antidote) to minimize tissue necrosis.

How to Approach the Question

• Identify the core clinical event from the stem: An IV catheter has dislodged, and fluid is now in the subcutaneous tissue, causing local swelling.
• Analyze the type of fluid involved: The patient is being treated for 'dehydration,' which implies a standard, non-vesicant solution (e.g., Normal Saline).
• Evaluate the options based on their precise definitions. The key is to differentiate between local vs. systemic and vesicant vs. non-vesicant complications.
• Rule out 'Infection' and 'Fluid overload' as they present with different signs (inflammation for infection, systemic respiratory/cardiac signs for overload).
• Differentiate between the two most similar options: 'Infiltration' (non-vesicant fluid) and 'Extravasation' (vesicant fluid). Since the fluid is for simple hydration, 'Infiltration' is the most accurate term.

Concept Tested & Keywords

• Concept Tested: Complications of Intravenous (IV) Therapy
• Stem keywords: IV fluids, dehydration, catheter slipped out, swelling
• Lead-in keywords: best describes
• Clinical cues: The key cue is 'swelling' at the IV site after the catheter 'slipped out', indicating a local issue with fluid placement.
• Clinical cues: The fluid is for 'dehydration', implying a non-vesicant solution like Normal Saline.
