Which complication of fractures is a severe condition that results from increased pressure within a closed space?

In a greenstick fracture, the bone bends and partially breaks, usually occurring in children due to the flexibility of their bones.

a. Transverse fracture: A transverse fracture occurs when the bone breaks straight across its long axis, not bending.
b. Oblique fracture: An oblique fracture involves a diagonal break, not bending and partial breaking.
d. Avulsion fracture: An avulsion fracture occurs when a piece of bone is torn away by a ligament or tendon, not bending and partial breaking.

Using a lift sheet to reposition the patient is essential to prevent skin breakdown and pressure ulcers in a patient with long-term immobilization. This helps redistribute pressure on bony prominences and reduces the risk of skin damage.

a. Performing passive range of motion exercises regularly is important for preventing joint stiffness and muscle atrophy but may not directly prevent skin breakdown and pressure ulcers.
b. Applying petroleum jelly to the skin under the immobilization device is not recommended, as it can cause skin maceration and compromise the device's fit and function.
d. Providing a soft foam mattress overlay can enhance patient comfort but may not be sufficient to prevent skin breakdown and pressure ulcers in patients with prolonged immobilization.
