✍️ Sample OCC Questions & Answers
1. 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.
2. 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.
3. Which structure connects muscles to bones?
Tendons are strong, fibrous connective tissues that serve to connect muscles to bones. They are essential for transmitting the force generated by muscle contractions to the skeletal system, thereby facilitating movement. In contrast, ligaments connect bones to other bones, providing stability to joints.
4. After cast removal, which skin finding requires the clinician's evaluation before the patient is discharged?
Any open wound or pressure injury discovered post-removal must be assessed by the clinician for infection and wound care planning.
5. Testing motor function of the ulnar nerve is best accomplished by asking the patient to:
Finger abduction is performed by the dorsal interossei, which are innervated by the ulnar nerve, making this the primary motor test for ulnar integrity.
6. Which color-coded system is used to guide padding at vulnerable areas in pediatric casts?
Padding placement in pediatric casts is guided by anatomical landmarks rather than a color-coded system; extra padding is placed over identified bony prominences.
