Question 1

Which instrument is used to hold the edges of a wound apart during wound closure to facilitate suturing?

Accepted Answer

Skin hooks

Answer

Skin hooks are small, sharp hooks that gently retract wound edges without crushing tissue, facilitating precise suture placement during closure.

Question 2

The CUSA (Cavitron Ultrasonic Surgical Aspirator) is used primarily for:

Accepted Answer

Fragmenting and aspirating soft tissue tumors with minimal blood loss

Answer

The CUSA uses ultrasonic vibration to selectively fragment soft tissue (such as tumors) while sparing blood vessels and bile ducts, then aspirates the debris.

Question 3

Which instrument is used to measure the depth of a bone tunnel during ACL reconstruction?

Accepted Answer

Depth gauge

Answer

A depth gauge is inserted into the bone tunnel to measure its depth, ensuring proper graft length selection during ACL reconstruction.

Question 4

A Penrose drain differs from a Jackson-Pratt drain in that the Penrose drain:

Accepted Answer

Is a passive drain with no suction mechanism

Answer

A Penrose drain is a soft rubber tube that passively allows fluid to drain by gravity and capillary action, while a Jackson-Pratt uses closed active suction.

Question 5

Which type of laser is most commonly used in ophthalmologic procedures for retinal photocoagulation?

Accepted Answer

Argon laser

Answer

The argon laser produces green light that is selectively absorbed by hemoglobin and retinal pigment epithelium, making it ideal for retinal photocoagulation.
