Which of the following is a common complication of pressure ulcers?

Infection is a common complication of pressure ulcers because the integrity of the skin is compromised, making it easier for bacteria to enter the body. When skin tissue is damaged due to prolonged pressure, it can lead to open wounds where pathogens can proliferate. These infections can range from superficial localized infections to more serious systemic infections, such as cellulitis or sepsis, especially if the underlying tissues become involved.

Effective wound care and regular repositioning of patients are essential to reduce the risk of such infections. The other options—severe dehydration, hypotension, and heart failure—are not direct complications of pressure ulcers. While they can be associated with general health issues in individuals, they do not specifically arise as a consequence of pressure ulcers themselves.
