Question: 1 / 400

What is a beginning sign of a pressure sore?

Swelling

Numbness

Discoloration

Discoloration is a key initial indicator of a pressure sore. When tissue is subjected to prolonged pressure, it can result in changes to the skin color, which may appear as redness or purple discoloration over bony areas. This occurs due to reduced blood flow, leading to a lack of oxygen (ischemia) in the affected tissue. Early recognition of this discoloration is crucial as it can signal the beginning of tissue damage, prompting timely intervention to relieve pressure and improve blood circulation, potentially preventing the progression to a more serious sore.

While swelling, numbness, and coolness can be associated with pressure-related injuries, they typically signify more advanced issues than the early signs represented by skin discoloration. Recognizing discoloration as a starting point allows caregivers to monitor skin integrity closely and take appropriate preventive actions.
