1. What is the primary risk factor for developing avascular necrosis of the femoral head?
A. Diabetes
B. Corticosteroid use
C. Osteoarthritis
D. Smoking
Answer: B. Corticosteroid use
Rationale: Prolonged corticosteroid use is a significant risk factor for avascular necrosis
due to compromised blood supply.
2. Which nerve is most at risk with a humeral shaft fracture?
A. Median nerve
B. Radial nerve
C. Ulnar nerve
D. Axillary nerve
Answer: B. Radial nerve
Rationale: The radial nerve runs along the humeral shaft and is commonly injured with
fractures in this area.
3. Which imaging modality is most sensitive for diagnosing stress fractures?
A. X-ray
B. MRI
C. CT scan
D. Ultrasound
Answer: B. MRI
Rationale: MRI is the most sensitive imaging modality for detecting stress fractures,
especially in their early stages.
,4. What is the main indication for a halo vest?
A. Lumbar spine stabilization
B. Thoracic spine stabilization
C. Cervical spine immobilization
D. Sacral spine support
Answer: C. Cervical spine immobilization
Rationale: Halo vests provide maximum immobilization of the cervical spine.
5. What is the primary purpose of a figure-of-eight bandage?
A. Immobilize the clavicle
B. Stabilize the wrist
C. Support the knee
D. Align the ankle
Answer: A. Immobilize the clavicle
Rationale: The figure-of-eight bandage is commonly used to immobilize clavicle fractures.
6. Which nerve is commonly affected in carpal tunnel syndrome?
A. Ulnar nerve
B. Median nerve
C. Radial nerve
D. Axillary nerve
Answer: B. Median nerve
Rationale: Compression of the median nerve in the carpal tunnel causes symptoms of
carpal tunnel syndrome.
7. What is the primary concern in a patient with a pelvic fracture?
A. Nerve damage
B. Vascular injury
C. Compartment syndrome
, D. Osteomyelitis
Answer: B. Vascular injury
Rationale: Pelvic fractures often cause significant bleeding due to vascular injury.
8. What is the most common site for a slipped capital femoral epiphysis (SCFE)?
A. Distal femur
B. Femoral head
C. Proximal femur
D. Femoral neck
Answer: C. Proximal femur
Rationale: SCFE occurs at the proximal femoral epiphysis, commonly in adolescents.
9. Which type of splint is most appropriate for a suspected distal radius fracture?
A. Sugar-tong splint
B. Posterior long arm splint
C. Volar wrist splint
D. Ulnar gutter splint
Answer: A. Sugar-tong splint
Rationale: A sugar-tong splint immobilizes the wrist and forearm, preventing supination
and pronation.
10. What is the primary goal of traction in orthopedic treatment?
A. Relieve pain
B. Promote bone healing
C. Reduce muscle spasm
D. All of the above
Answer: D. All of the above
Rationale: Traction is used for pain relief, muscle spasm reduction, and promoting proper
alignment and healing.
A. Diabetes
