Which statement is true about pressure injuries?

1. They are usually caused by exercising too much.

2. They are difficult to heal but do not hurt much.

3. They are impossible to prevent.

4. They can lead to life-threatening infections.

The correct answer is: They can lead to life-threatening infections.

Pressure injuries, also known as pressure ulcers or bedsores, occur when prolonged pressure on the skin restricts blood flow to the area, often affecting those who are immobile for long periods. The correct statement highlights a significant concern associated with pressure injuries: they can lead to life-threatening infections. When the skin and underlying tissue break down due to pressure, the integrity of the barrier that protects against pathogens is compromised. This can allow bacteria to enter the body, potentially resulting in serious infections, such as cellulitis, sepsis, or osteomyelitis. Such complications can be particularly dangerous for individuals with weakened immune systems or pre-existing health conditions, emphasizing the importance of appropriate care and prevention measures. Understanding this risk underscores the need for careful monitoring, regular repositioning of individuals at risk, and ensuring proper skin care to prevent the development of pressure injuries and the severe consequences they may bring.
