Question 1

When applying a short arm cast for a distal radius fracture, the wrist should typically be positioned in how many degrees of flexion?

Accepted Answer

0–5 degrees (neutral)

Answer

A neutral or very slight flexion position (0–5 degrees) is standard for most distal radius fractures to minimize tendon strain and maintain reduction.

Question 2

Which complication is most directly indicated by a patient reporting a 'burning' sensation under a freshly applied cast?

Accepted Answer

Thermal burn from exothermic reaction

Answer

Plaster of Paris generates heat during the exothermic setting reaction, and a burning sensation shortly after application suggests a thermal burn risk.

Question 3

For a long arm cast, the elbow is most commonly positioned at what angle?

Accepted Answer

90 degrees of flexion

Answer

A 90-degree elbow flexion is the standard position for a long arm cast to balance functional use and fracture stability.

Question 4

Which type of stockinette is used directly against the skin before applying cast padding?

Accepted Answer

Cotton tubular stockinette

Answer

Cotton tubular stockinette is applied first to protect the skin and provide a smooth base layer before cast padding and casting material.

Question 5

After applying a fiberglass cast, the orthopaedic technologist instructs the patient not to bear weight for how long until the cast reaches full strength?

Accepted Answer

2 hours

Answer

Fiberglass casts achieve handling strength quickly but require approximately 30 minutes to 2 hours to reach full weight-bearing strength.
