ABSA Surgical Assistant Exam Prep
2026/2027 | 200 Verified Questions and
Answers | American Board of Surgical
Assistant Certification Study Guide
• This 200-question ABSA Surgical Assistant Exam Prep guide covers the full scope
of the American Board of Surgical Assistant certification blueprint — from surgical
anatomy and instrumentation to patient safety and postoperative care.
• Study by working through each question independently before reading the correct
answer and EXPERT RATIONALE; focus extra review time on any topic where you
miss two or more consecutive questions.
1. Which layer of the abdominal wall is encountered immediately deep to the
skin during a midline laparotomy?
A. External oblique fascia
B. Rectus abdominis muscle
C. Subcutaneous fatty tissue (Camper's fascia)
D. Scarpa's fascia
E. Linea alba
C. Subcutaneous fatty tissue (Camper's fascia)
EXPERT RATIONALE: During a midline laparotomy, the first layer encountered after
the skin incision is Camper's fascia, the superficial fatty layer of the subcutaneous
tissue. Scarpa's fascia lies just beneath it, followed by the linea alba.
2. The surgical assistant is responsible for maintaining which of the following
throughout a procedure?
A. Anesthesia depth monitoring
B. Sterile field integrity
C. Postoperative documentation only
,D. Medication dosage calculations
E. Anesthesia machine settings
B. Sterile field integrity
EXPERT RATIONALE: Maintaining the sterile field is a core responsibility of the
surgical assistant. Any break in sterile technique must be immediately identified
and corrected to prevent surgical site infection.
3. Which suture material is most appropriate for closing the fascia in a
midline laparotomy?
A. Plain gut
B. Chromic gut
C. Polypropylene (Prolene)
D. Polyglactin 910 (Vicryl)
E. Fast-absorbing gut
C. Polypropylene (Prolene)
EXPERT RATIONALE: Polypropylene is a non-absorbable monofilament suture with
excellent tensile strength, making it ideal for fascial closure where long-term
strength retention is required to prevent incisional hernia.
4. When using electrosurgery, the active electrode concentrates current to
produce which effect?
A. Cooling of surrounding tissue
B. Hemostasis through freezing
C. Heat generation causing cutting or coagulation
D. Ultrasonic tissue disruption
E. Laser photocoagulation
, C. Heat generation causing cutting or coagulation
EXPERT RATIONALE: Electrosurgery works by passing high-frequency electrical
current through tissue via the active electrode, generating heat at the point of
contact. Depending on waveform, this produces cutting (continuous current) or
coagulation (interrupted current).
5. Which nerve is at greatest risk during a laparoscopic cholecystectomy if the
triangle of Calot is not properly dissected?
A. Vagus nerve
B. Right phrenic nerve
C. Common bile duct (not a nerve but frequently confused)
D. Right hepatic artery
E. Cystic artery
D. Right hepatic artery
EXPERT RATIONALE: The right hepatic artery is at significant risk during
laparoscopic cholecystectomy if the critical view of safety within the triangle of
Calot is not achieved before clipping. Misidentification can lead to catastrophic
vascular injury.
6. Which position is used for procedures involving the rectum, perineum, and
gynecological surgeries?
A. Trendelenburg
B. Reverse Trendelenburg
C. Lithotomy
D. Lateral decubitus
E. Prone jackknife
, C. Lithotomy
EXPERT RATIONALE: The lithotomy position places the patient supine with legs
elevated and abducted in stirrups, providing optimal access to the perineum,
rectum, and pelvic organs for procedures such as hemorrhoidectomy,
hysterectomy, and cystoscopy.
7. What is the primary purpose of a Bookwalter retractor system?
A. Laparoscopic port placement
B. Self-retaining exposure in deep abdominal and pelvic surgery
C. Skin closure assistance
D. Vascular clamping
E. Wound irrigation
B. Self-retaining exposure in deep abdominal and pelvic surgery
EXPERT RATIONALE: The Bookwalter is a self-retaining retractor system that
attaches to the operating table and uses interchangeable blades to provide
sustained, hands-free retraction in deep cavities such as the abdomen and pelvis.
8. Which of the following is the MOST important action before draping a
surgical patient?
A. Applying the electrosurgical grounding pad
B. Confirming the correct surgical site has been marked and verified
C. Adjusting the OR table height
D. Positioning the back table
E. Opening sterile instrument sets
B. Confirming the correct surgical site has been marked and verified
