Hint : 🛏️Pressure blocks perfusion.

Correct Answers:

  • Pressure ulcers are caused by occlusion of arterial vessels to a tissue area


Rationale :

🔷 Pressure ulcers develop when prolonged pressure compresses blood vessels supplying tissue.

🔷 This pressure reduces oxygen and nutrient delivery to the skin and underlying tissue.

🔷 When tissue perfusion is decreased for a prolonged time, ischemia occurs.

🔷 Continued ischemia leads to cell death, skin breakdown, and ulcer formation.

🔷 Common sites include bony prominences such as the sacrum, heels, hips, and elbows.

Pressure ulcers are caused by venous stasis surrounding a flesh area

🔷Venous stasis causes pooling of blood and can contribute to venous ulcers, especially in the lower legs.

🔷 Pressure injuries are primarily caused by prolonged pressure that reduces tissue perfusion.

Pressure ulcers are caused by fibrous collagen growth with immobility

🔷Fibrous collagen growth is associated with scar tissue formation and wound healing.

🔷It is not the main cause of pressure ulcer formation.

Pressure ulcers are caused by anaerobic bacteria pooling on the skin

🔷Bacteria can infect an existing wound, but they do not cause the initial pressure injury.

🔷The primary cause is pressure-related ischemia.
