Final answer:
Coolness around an IV injection site can be indicative of infiltration, which occurs when IV fluid leaks into surrounding tissue instead of entering the vein properly.
Step-by-step explanation:
If the area around the IV injection site feels cool, it may indicate that the IV fluid is not being absorbed properly into the body and may be leaking into the surrounding tissue. This condition is known as infiltration, where the IV fluid escapes from the vein into the subcutaneous tissue. Infiltration can lead to tissue damage, and it is important for healthcare professionals to assess the situation promptly. Signs of infiltration include swelling, coolness at the site, pain, and a slow or stopped IV flow. Prompt action is needed to prevent complications such as phlebitis or infection.
