Explanation

Phlebitis is defined as the inflammation of a vein's inner layer (tunica intima).
The symptoms listed in the question—redness (erythema), heat (warmth), and tenderness—are the cardinal signs of inflammation, which is the hallmark of phlebitis.
A decreased IV flow rate is a common accompanying sign, as the inflamed vein may narrow or a thrombus may begin to form, impeding the flow of fluid.

Option A: Infiltration is incorrect because it is characterized by coolness, pallor (blanched skin), and swelling due to fluid leaking into the subcutaneous tissue, not the inflammatory signs of redness and heat.
Option C: An allergic reaction is a systemic immune response. While it can cause redness (as part of a rash or hives), it is typically widespread and accompanied by itching (pruritus) and potentially systemic symptoms like wheezing or hypotension, not localized heat and tenderness at the IV site.
Option D: Hypersensitivity is a broad term for an exaggerated immune response, including allergic reactions. Like an allergic reaction, it would manifest with systemic signs rather than the localized inflammation described in the question.

Clinical Relevance

Nursing practice connection: Use the key finding related to Assessment of Intravenous (IV) Therapy Complications to guide bedside assessment, documentation, and the next nursing action.
Regular and frequent assessment of IV sites (e.g., every 1-2 hours for adults) is a fundamental nursing responsibility to detect complications early and prevent progression to more severe conditions like thrombophlebitis, tissue damage, or bloodstream infections.
A simple tactile assessment is a key differentiator: a site that feels warm suggests phlebitis, while a site that feels cool suggests infiltration.
What if? If the fluid being infused was a vesicant (e.g., chemotherapy, vancomycin, or high-concentration potassium), the complication would be extravasation, not just infiltration. Extravasation can cause severe tissue damage, blistering, and necrosis, requiring immediate and specific antidote protocols, making prompt identification even more critical.

How to Approach the Question

First, break down the signs presented in the question: redness, heat, tenderness, and a decreased flow rate.
Recognize that 'redness,' 'heat,' and 'tenderness' are the classic, cardinal signs of inflammation.
Next, analyze the options in the context of inflammation. The term 'phlebitis' has the suffix '-itis,' which means inflammation, and the root 'phleb-,' which means vein. Therefore, phlebitis is inflammation of a vein.
Contrast this with the other options. Infiltration is leakage of fluid, which causes coolness and pallor. Allergic reactions are systemic and present with different signs like hives and itching.
By matching the signs of inflammation in the stem to the definition of phlebitis, you can confidently select the correct answer.
