Practice Questions & Detailed Solutions
ABSA SA-C EXAM STUDY GUIDE 2026/2027
Overview:
• This study guide contains 200 comprehensive practice questions designed to
prepare you for the American Board of Surgical Assistants (ABSA) SA-C certification
exam, covering all major domains including surgical anatomy, physiology,
pathology, pharmacology, patient safety, sterile technique, hemostasis, anesthesia,
and clinical procedures.
• Study this material systematically by reviewing each question, attempting to
answer before reviewing the correct answer and rationale, and focusing on
understanding the principles behind each answer to build competency across all
exam domains.
1. What is the primary role of the surgical assistant in maintaining sterile field
integrity?
A) Performing surgical procedures independently
B) Monitoring patient vital signs throughout the case
C) Preventing contamination by maintaining awareness of the sterile boundary and
ensuring only sterile items contact the field
D) Administering anesthesia to the patient
E) Documenting all medications used during surgery
CORRECT ANSWER: C) Preventing contamination by maintaining awareness of
the sterile boundary and ensuring only sterile items contact the field
RATIONALE: The surgical assistant's primary responsibility in sterile technique is to
actively maintain the sterile field by understanding the principles of sterile versus
,non-sterile areas. This includes never reaching over a sterile field, keeping sterile
items above waist level, and ensuring all items contacting the surgical field are
sterile. This is a fundamental principle of asepsis and prevents surgical site
infections.
2. Which of the following best describes the blood supply to the rectus
abdominis muscle?
A) Superior epigastric artery only
B) Inferior epigastric artery only
C) Superior and inferior epigastric arteries with segmental intercostal and lumbar
arteries
D) Celiac axis exclusively
E) Only the femoral artery
CORRECT ANSWER: C) Superior and inferior epigastric arteries with segmental
intercostal and lumbar arteries
RATIONALE: The rectus abdominis receives its blood supply from multiple sources:
the superior epigastric artery (continuation of the internal thoracic artery), the
inferior epigastric artery, and segmental intercostal and lumbar arteries.
Understanding this vascular anatomy is critical when performing abdominal
procedures to prevent excessive bleeding and recognize potential hemorrhage
sources.
3. What is the mechanism of action of heparin in anticoagulation?
A) It inhibits thrombin directly
B) It potentiates antithrombin III to inactivate factors IIa and Xa
C) It inhibits platelet aggregation
D) It promotes fibrinolysis
,E) It vitamin K antagonist
CORRECT ANSWER: B) It potentiates antithrombin III to inactivate factors IIa
and Xa
RATIONALE: Heparin works by enhancing the activity of antithrombin III, a natural
anticoagulant in the body. This complex inactivates thrombin (factor IIa) and factor
Xa, preventing the propagation phase of coagulation. Understanding heparin's
mechanism is essential for managing anticoagulation during surgical procedures
and recognizing when reversal with protamine is necessary.
4. During a laparoscopic cholecystectomy, which anatomical structure must
be clearly identified to prevent major vascular injury?
A) The cystic artery
B) The common bile duct
C) The hepatic artery proper
D) The portal vein
E) The superior mesenteric artery
CORRECT ANSWER: C) The hepatic artery proper
RATIONALE: While the cystic artery and common bile duct are important structures
in cholecystectomy, the hepatic artery proper is critical because it runs in close
proximity to the hepatocystic triangle. Inadvertent ligation or transection of the
hepatic artery proper would result in hepatic necrosis and is one of the most
serious complications of cholecystectomy. Proper identification of the critical view
of safety helps prevent this complication.
5. What is the most appropriate position for a patient undergoing a lumbar
laminectomy?
A) Supine with knees flexed
B) Prone with the spine hyperextended
, C) Prone with a bolster under the abdomen to maintain neutral spine and reduce
epidural bleeding
D) Lithotomy position
E) Reverse Trendelenburg
CORRECT ANSWER: C) Prone with a bolster under the abdomen to maintain
neutral spine and reduce epidural bleeding
RATIONALE: For lumbar laminectomy, the prone position with abdominal support
is ideal. The bolster prevents abdominal compression and vena cava compression,
which would increase epidural venous bleeding. The bolster also maintains lumbar
lordosis in neutral position, improving visibility of the surgical field and reducing
bleeding from epidural vessels—a critical consideration in spinal surgery.
6. Which layer of the abdominal wall is responsible for most of the tensile
strength in surgical repairs?
A) The skin
B) The subcutaneous tissue
C) The fascia (rectus sheath and aponeurosis)
D) The peritoneum
E) The muscle itself
CORRECT ANSWER: C) The fascia (rectus sheath and aponeurosis)
RATIONALE: The fascia provides approximately 90% of the tensile strength in
abdominal wall repairs. When closing abdominal incisions, it is critical to achieve
excellent fascial approximation with appropriate suture material and technique.
Neglecting proper fascial closure significantly increases the risk of wound
dehiscence and hernia formation, even if skin closure is performed well.
7. What is the correct sequence for applying a sterile surgical drape?
