✍️ Sample OCC Questions & Answers
1. Which patient population has the HIGHEST risk for developing pressure ulcers beneath a cast?
Elderly patients with neuropathy cannot perceive warning pain, and their fragile skin has reduced tolerance to sustained pressure.
2. A 'three-point pressure system' in cast molding refers to which concept?
Three-point molding applies a corrective force at the fracture apex balanced by opposing forces proximal and distal, maintaining fracture reduction within the cast.
3. Which sign is most concerning for compartment syndrome in a casted limb?
Severe pain that is disproportionate to the injury and unrelieved by standard analgesics is the most concerning sign for compartment syndrome in a casted limb. This condition occurs when increased pressure within a confined muscle compartment compromises circulation and nerve function. It is a medical emergency requiring immediate intervention to prevent permanent tissue damage.
4. What is the approximate full weight-bearing time after application of a standard plaster long leg cast for a stable fracture?
Plaster reaches adequate strength for limited weight-bearing within 24–48 hours as it fully dries and crystallizes, though physician guidance determines timing.
5. Which information is REQUIRED to be included on every cast application record?
A complete cast record includes procedure details, materials, neurovascular findings, and technician identification to ensure accountability and continuity of care.
6. Which of the 'five P's' of compartment syndrome represents the LATEST and most ominous sign?
Pulselessness is a very late sign indicating arterial occlusion; by this stage irreversible muscle and nerve necrosis is likely already occurring.
