During a carotid endarterectomy, the surgical technologist should have which shunt available to maintain cerebral perfusion while the carotid artery is clamped?
Answer: Pruitt-Inahara shunt
The Pruitt-Inahara shunt has balloon tips that secure within both the common and internal carotid arteries, providing continuous blood flow during endarterectomy.
In a Whipple procedure (pancreaticoduodenectomy), which anastomosis is performed last?
Answer: Gastrojejunostomy
The gastrojejunostomy (reconnection of the stomach to the jejunum) is the final anastomosis performed in the Whipple procedure reconstruction phase.
When setting up for a radical mastectomy, the scrub technologist should prepare for sentinel lymph node biopsy by having which substance available for injection?
Answer: Isosulfan blue dye
Isosulfan blue (Lymphazurin) is injected peritumorally to visually identify the sentinel lymph node by staining lymphatic channels blue.
During spinal fusion surgery, which positioning device is most commonly used to reduce intra-abdominal pressure and minimize surgical bleeding?
Answer: Wilson frame
The Wilson frame allows the abdomen to hang freely, reducing intra-abdominal pressure that would otherwise impede venous return and increase epidural bleeding.
A surgeon requests 'Weitlaner' during a deep tissue dissection. What type of instrument should the scrub tech pass?
Answer: Self-retaining retractor
The Weitlaner is a self-retaining retractor with sharp or blunt prongs that lock open to hold tissue apart without an assistant holding it.
During a Nissen fundoplication, the scrub tech should anticipate bougie esophageal dilator sizes typically ranging from:
Answer: 52–60 French
A 52–60 French bougie is passed transorally into the esophagus to calibrate the wrap tightness and prevent postoperative dysphagia.
When performing a femoral-popliteal bypass, the graft of first choice when autologous vein is unavailable is:
Answer: PTFE (polytetrafluoroethylene) graft
PTFE grafts are the preferred synthetic conduit for infrainguinal bypass when autologous saphenous vein is unavailable due to their acceptable patency rates.
