Pressure ulcers are directly caused by which of the following conditions at the site?
A) Compromised blood flow
B) Edema
C) Shearing forces
D) Inadequate venous return
Pressure Ulcers
Injuries to the skin and underlying tissue, primarily caused by prolonged pressure on the skin, often occurring in bedridden patients.
Shearing Forces
Stresses that cause layers of material to slide past one another, often leading to structural failure or injury.
Compromised Blood Flow
A condition where the normal circulation of blood is hindered, leading to inadequate oxygen and nutrient delivery to tissues.

Final Answer :
A
Explanation :
Pressure ulcers are caused by unrelieved pressure that compromises blood flow to an area,resulting in ischemia (inadequate blood supply)in the underlying tissue.Friction and shear are extrinsic factors affecting skin integrity,which increases the risk of a client developing a pressure ulcer but is not the direct cause.Inadequate arterial blood flow to an area as a result of pressure causes the development of a pressure ulcer.Edema leads to compromised skin and tissue integrity,which is more prone to pressure injury.
