During a laparoscopic cholecystectomy, the surgical technologist should anticipate the need for which instrument to dissect the hepatocystic triangle?
Answer: Maryland dissector
The Maryland dissector is the standard instrument for blunt and sharp dissection of the hepatocystic triangle to expose the cystic duct and artery.
When setting up for an open appendectomy, which incision is most commonly used?
Answer: McBurney incision
The McBurney incision is a muscle-splitting incision made at McBurney's point (1/3 the distance from ASIS to umbilicus) providing direct access to the appendix.
During a total hip arthroplasty, the scrub technologist should have which type of saw ready for femoral neck osteotomy?
Answer: Oscillating saw
An oscillating saw is used for femoral neck osteotomy because its back-and-forth blade motion minimizes soft tissue damage during bone cutting.
A patient is undergoing a CABG procedure. After harvesting the saphenous vein, the scrub tech should ensure the graft is stored in which solution?
Answer: Heparinized normal saline
Heparinized normal saline prevents clotting and maintains vessel viability during the period between harvest and anastomosis.
During a thyroidectomy, identification and preservation of which structure is the primary concern to prevent postoperative voice hoarseness?
Answer: Recurrent laryngeal nerve
The recurrent laryngeal nerve innervates the intrinsic muscles of the larynx and its injury causes hoarseness or loss of voice.
When assisting with a craniotomy, which instrument does the scrub tech pass to elevate the bone flap after burr holes are connected?
Answer: Penfield dissector
The Penfield dissector (typically No. 3) is used to separate the dura from the inner table of the skull before elevating the bone flap.
During a transurethral resection of the prostate (TURP), which irrigating solution is used to prevent electrical current dispersion?
Answer: Glycine 1.5%
Glycine 1.5% is a non-electrolyte, non-hemolytic solution that does not disperse monopolar electrical current used during TURP resection.
