Question 1

During a hip arthroplasty, the patient is positioned in a lateral decubitus position. Which anatomical landmark is most critical to pad to prevent a pressure injury?

Accepted Answer

Lateral knee (fibular head/peroneal nerve)

Accepted Answer

Exsanguinate the extremity before tourniquet inflation

An Esmarch bandage wraps the limb distally to proximally to exsanguinate it before tourniquet inflation, creating a bloodless surgical field.

Question 3

When setting up the back table for a shoulder rotator cuff repair, which instrument is essential for suture anchor placement?

Accepted Answer

Awl and mallet

Answer

Suture anchors require an awl to create a pilot hole and a mallet to drive the anchor into bone during rotator cuff repair.

Question 4

During an external fixator application for a tibia fracture, the OT's role when handling Schanz pins includes:

Accepted Answer

Ensuring pins remain sterile and loading them into the drill chuck without contaminating threads

Answer

Schanz pins must remain sterile throughout; the OT loads them into the chuck carefully to avoid contaminating the bone-contact threads.

Question 5

Bone cement (PMMA) preparation in orthopaedic surgery requires the OT to:

Accepted Answer

Mix cement under a fume hood or in a vacuum mixing system and monitor working time

PMMA cement produces toxic methyl methacrylate fumes; vacuum mixing or fume management is required, and the OT must track working time as it sets quickly.
