CNJNE IV Therapy Practice Test for Adults – Complete Exam Prep 2025

The symptoms of swelling, discomfort, and coolness at the insertion site are hallmark signs of IV infiltration. When an IV line becomes infiltrated, the solution intended for the bloodstream leaks into the surrounding tissue instead. This can lead to localized swelling as the fluid accumulates in the interstitial spaces. The discomfort often arises from the pressure and stretching of the tissue, and the coolness can occur due to a lack of blood flow from the infiltrated area. These symptoms are critical for healthcare providers to recognize quickly, as timely intervention can help prevent further complications such as tissue damage.

In contrast, the other options describe symptoms that are not typically associated with infiltration. Increased blood pressure and fever are more indicative of systemic issues rather than localized infiltration. Severe headache and dizziness can be related to a variety of other conditions but do not directly correlate with issues stemming from an IV line. Lastly, increased heart rate and anxiety could be a response to pain or discomfort but again, do not specifically point to infiltration. Recognizing the correct symptoms is essential for effective management of IV therapy complications.
