Question 1

Which position places the knee in approximately 20–30 degrees of flexion and is recommended for a long leg posterior splint?

Accepted Answer

Slight flexion (20–30 degrees)

Answer

A long leg posterior splint positions the knee in 20–30 degrees of flexion, which is the functional resting position and reduces tension on posterior structures.

Question 2

The 'terrible triad' injury of the elbow consists of posterior elbow dislocation combined with fractures of which two structures?

Accepted Answer

Radial head and coronoid process

Answer

The terrible triad of the elbow is posterior dislocation combined with radial head fracture and coronoid process fracture, leading to significant instability.

Question 3

In which scenario is a sugar tong splint most appropriately indicated?

Accepted Answer

Distal radius fracture with swelling

Answer

A sugar tong splint immobilizes the wrist and prevents forearm rotation, making it ideal for acute distal radius and ulna fractures when swelling precludes circumferential casting.

Question 4

Under standard infection control guidelines, an orthopaedic technologist should perform hand hygiene at minimum at which of the following times?

Accepted Answer

Before patient contact, before aseptic tasks, after body fluid exposure, after patient contact, after touching patient surroundings

Answer

WHO's 'Five Moments for Hand Hygiene' requires hand hygiene before patient contact, before aseptic tasks, after body fluid risk, after patient contact, and after touching patient surroundings.

Accepted Answer
