Which of the following terms refers specifically to an ulcer caused by pressure?

The term that specifically refers to an ulcer caused by pressure is "pressure ulcer." This type of ulcer develops when sustained pressure on the skin leads to tissue damage. Pressure ulcers commonly occur in areas where bones are close to the skin, particularly in individuals who are immobile for extended periods, such as those in a hospital or nursing home setting. They can develop rapidly and are often classified by stages based on their severity and depth.

By recognizing the characteristics of a pressure ulcer, healthcare professionals can implement preventive measures such as repositioning patients, using specialized bedding, and maintaining skin hygiene to reduce the risk of pressure-related injuries.

In contrast, other types of ulcers mentioned focus on different underlying issues. For example, stasis ulcers are associated with poor venous circulation, while diabetic ulcers are often related to neuropathy and poor blood flow in patients with diabetes. Venous ulcers occur due to complications with veins, typically caused by chronic venous insufficiency. Each of these has distinct causes and risk factors that differentiate them from pressure ulcers.
