Which instrument is used to hold the edges of a wound apart during wound closure to facilitate suturing?
Answer: Skin hooks
Skin hooks are small, sharp hooks that gently retract wound edges without crushing tissue, facilitating precise suture placement during closure.
The CUSA (Cavitron Ultrasonic Surgical Aspirator) is used primarily for:
Answer: Fragmenting and aspirating soft tissue tumors with minimal blood loss
The CUSA uses ultrasonic vibration to selectively fragment soft tissue (such as tumors) while sparing blood vessels and bile ducts, then aspirates the debris.
Which instrument is used to measure the depth of a bone tunnel during ACL reconstruction?
Answer: Depth gauge
A depth gauge is inserted into the bone tunnel to measure its depth, ensuring proper graft length selection during ACL reconstruction.
A Penrose drain differs from a Jackson-Pratt drain in that the Penrose drain:
Answer: Is a passive drain with no suction mechanism
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.
Which type of laser is most commonly used in ophthalmologic procedures for retinal photocoagulation?
Answer: Argon laser
The argon laser produces green light that is selectively absorbed by hemoglobin and retinal pigment epithelium, making it ideal for retinal photocoagulation.
During instrumentation setup, instruments should be organized on the back table according to:
Answer: The order of use during the procedure
Instruments are arranged on the back table in the order they will be used during the procedure to allow efficient, rapid passing without searching.
The function of a 'pledget' in cardiovascular surgery is to:
Answer: Reinforce sutures placed in friable cardiac tissue
Pledgets are small pieces of felt or Teflon used to reinforce sutures in fragile cardiac tissue, distributing tension and preventing sutures from tearing through.
