Question 1

A patient with a hip fracture has been placed on 'hip precautions.' Which motion should be avoided following a posterior approach total hip replacement?

Accepted Answer

Hip flexion beyond 90°

Answer

After a posterior approach total hip replacement, hip flexion beyond 90° combined with internal rotation and adduction risks posterior dislocation.

Question 2

Which muscle is the primary stabilizer of the glenohumeral joint inferiorly?

Accepted Answer

Supraspinatus

Answer

The supraspinatus is the primary stabilizer against inferior subluxation of the glenohumeral joint due to its superior cuff position and tension.

Question 3

What is the close-packed position of the knee joint?

Accepted Answer

Full extension with tibial external rotation

Answer

The close-packed (maximally congruent) position of the knee is full extension with slight external tibial rotation, creating the screw-home mechanism.

Question 4

Which nerve is compressed in carpal tunnel syndrome?

Accepted Answer

Median nerve

Answer

Carpal tunnel syndrome results from compression of the median nerve within the carpal tunnel at the wrist.

Question 5

A PTA applies moist heat to reduce muscle spasm. What is the primary physiological effect?

Accepted Answer

Increased collagen extensibility and local vasodilation

Answer

Superficial heat application causes local vasodilation and increases collagen extensibility, which reduces muscle spasm and promotes relaxation.
