NCCT SURGICAL TECH PRACTICE EXAM AND STUDY GUIDE 2025 |
EXAM QUESTIONS AND CORRECT ANSWERS PLUS RATIONALES
(ALREADY GRADED A+)
Question 1
The surgical technologist is preparing for a laparoscopic assisted vaginal hysterectomy (LAVH).
Which advanced energy device is commonly used for dissecting tissue and coagulating vessels
during this procedure?
A) Bovie pencil with a needle tip
B) Harmonic scalpel
C) Argon beam coagulator
D) Cryosurgery unit
E) High-frequency electrosurgical generator only
Correct Answer: B) Harmonic scalpel
Rationale: The Harmonic Scalpel is an ultrasonic dissecting device that vibrates at a high
frequency to cut and coagulate tissue simultaneously with minimal thermal spread. It is ideal
for the precise dissection of vascular pedicles, such as the uterine arteries, required in an
LAVH. While a standard Bovie is used, the Harmonic provides superior hemostasis for delicate
structures. The argon beam is for large surface bleeding, and cryosurgery is for ablation, not
dissection.
Question 2
When preparing for a posterior spinal fusion of the thoracic and lumbar spine (T3-L2), which
specialized positioning frame is used to place the patient prone while allowing the abdomen to
hang free?
A) Wilson frame
B) Mayfield head frame
C) Bean bag
D) Fracture table
E) Allen stirrups
Correct Answer: A) Wilson frame
Rationale: The Wilson frame attaches to the OR table and supports the patient in a flexed
,prone position on padded rests. This position opens the vertebral spaces for easier surgical
access and allows the abdomen to be free from external pressure. This reduces intra-
abdominal pressure and minimizes venous bleeding from the epidural veins. The Mayfield
frame is for cranial procedures, a bean bag is for lateral positioning, and a fracture table is for
orthopedic traction.
Question 3
To create a bloodless surgical field during a total knee arthroplasty, which piece of equipment is
essential for occluding arterial blood flow to the limb?
A) Coban wrap
B) Stockinette
C) Pneumatic tourniquet
D) Esmarch bandage
E) Sequential compression device
Correct Answer: C) Pneumatic tourniquet
Rationale: A pneumatic tourniquet is a cuff connected to an inflation device that applies a
specific, controlled pressure to the limb, sufficient to stop arterial blood flow temporarily.
While an Esmarch bandage is used to exsanguinate the limb before inflation, and
Coban/stockinette are dressings/linings, only the tourniquet itself occludes the blood flow for
the duration of the procedure.
Question 4
The surgeon is starting an exploratory laparotomy on an elderly female patient with a very large,
rotund abdomen. Which combination of instrumentation should the surgical technologist
anticipate needing for exposure and potential procedures?
A) Laparoscopic instruments and a Bookwalter retractor
B) Bowel instrumentation and a Bookwalter retractor
C) Laparoscopic instruments and a Balfour retractor
D) Minor procedure tray and Weitlaner retractors
E) Vascular clamps and Army-Navy retractors
,Correct Answer: B) Bowel instrumentation and a Bookwalter retractor
Rationale: An exploratory laparotomy is an open procedure, so laparoscopic instruments are
not needed. Given the patient's size, a large, table-mounted retractor system like the
Bookwalter is necessary for adequate exposure of the deep abdominal cavity. "Exploratory"
implies the possibility of encountering any abdominal pathology, so a major set including
bowel instrumentation is required to be prepared.
Question 5
A patient is scheduled for a Video-Assisted Thoracoscopic Surgery (VATS). Which combination of
equipment is essential for patient positioning and visualization during this procedure?
A) Wilson frame, video tower, and sandbags
B) Bean bag, video tower, and positioning pillows/rolls
C) Fracture table, C-arm, and a microscope
D) Stirrups, video tower, and a uterine manipulator
E) Mayfield headrest, C-arm, and nerve integrity monitor
Correct Answer: B) Bean bag, video tower, and positioning pillows/rolls
Rationale: For a VATS procedure, the patient is placed in the lateral position. A bean bag is
used to secure the patient in this position once the air is evacuated. A video tower with a
camera and monitor is essential, as the "V" in VATS stands for video-assisted. Pillows and rolls
are used to pad pressure points and support the limbs in the lateral position to prevent nerve
injury.
Question 6
The surgical team conducts a time out, stating the patient's name, procedure, site, and known
allergies. Everyone concurs. For a total joint replacement case, what critical element, if omitted,
would render this briefing incomplete?
A) Verification of the patient's blood type
B) Confirmation of the postoperative destination
C) Verbal confirmation that all necessary implants are available in the room
, D) A statement of the estimated blood loss
E) Review of the patient's dietary restrictions
Correct Answer: C) Verbal confirmation that all necessary implants are available in the room
Rationale: For any procedure involving implants (e.g., orthopedic plates, screws, joint
prostheses, pacemakers), the time out must include a verification that the correct implants, in
the correct size and type, are physically present and available for the case. Proceeding
without this confirmation is a significant patient safety risk.
Question 7
According to The Joint Commission's Universal Protocol, which of the following represents the
three essential core components that must be verified during the final "time out" immediately
before the incision?
A) Patient's identity, patient's allergies, and surgeon's name
B) Patient's date of birth, correct site, and estimated procedure time
C) Correct patient, correct surgical site, and correct procedure
D) Correct procedure, availability of implants, and sterility of instruments
E) Patient's identity, consent form signature, and patient's blood type
Correct Answer: C) Correct patient, correct surgical site, and correct procedure
Rationale: The absolute minimum requirements for every time out are to confirm the correct
patient (using at least two identifiers), the correct anatomical site (which must be marked),
and the correct procedure that is planned. All other checks are important additions, but these
three are the mandatory foundation of the time out.
Question 8
The circulating nurse initiates a surgical time out while the surgeon is not yet present in the
room and states incorrect patient identifiers. Which of the following is the best action for the
surgical technologist to take?
A) Politely stop the process and state that the time out must be re-initiated when all team
members are present.
B) Report this sentinel event through the facility compliance hotline.
