Final answer:
The signs of a hematoma resulting from IV therapy complications include pain and bruising, in addition to redness and swelling which are indicative of inflammation.
Step-by-step explanation:
The signs of a hematoma as a complication of IV therapy are pain, bruising, redness, and swelling. When an IV is inserted, it can sometimes injure a blood vessel, leading to a leak of blood and its components out of the break, causing a hematoma. Recognizing the four cardinal signs of inflammation, which include redness, swelling, pain, and local heat as documented by Cornelius Celsus in the Roman Empire, is vital in identifying a hematoma. If a hematoma occurs after IV therapy, it is important to monitor for increased symptoms, as these could suggest additional complications.
