Final answer:
Infiltration can lead to symptoms like swelling around the insertion site and might occur with or without pain. Redness or warmth to touch could indicate an inflammatory response associated with infiltration, whereas 'cool to touch' is not typically associated with this condition.
Step-by-step explanation:
The term 'infiltration' in a medical context often refers to the process by which a substance, such as a drug or fluid, passes into or is introduced into a tissue, such as when an intravenous line leaks medication into the surrounding tissue. The symptoms that would be consistent with infiltration include swelling around the insertion site, which is a result of the fluid accumulating outside the vein, and with or without pain, depending on the individual's reaction to the infiltrating substance. While redness is a sign of inflammation, it would not necessarily be consistent with infiltration by itself. However, it may present if the infiltration causes irritation. Similarly, 'warm to touch' could indicate an inflammatory reaction to the infiltrated fluid. Conversely, 'cool to touch' is not typically associated with infiltration but rather with a reduced blood flow, which would not be characteristic of this condition.
