SECTION 1: IDENTIFICATION OF SURGICAL INSTRUMENTS BY
PROPER NAME (Questions 1-34)
,This section covers the largest domain of the CSIS exam (34%). Topics include
general instruments, retractors, laparoscopic and robotic instruments, power
equipment, and specialty instruments.
Question 1
Which instrument is used to clamp blood vessels and is characterized by a cross-
hatched pattern on the jaws?
A) Tissue forceps
B) Hemostat
C) Needle holder
D) Scissors
E) Retractor
Correct Answer: B
Rationale: A hemostat (such as a Kelly or Crile clamp) is used to clamp blood
vessels and is characterized by a cross-hatched (serrated) pattern on the jaws to
provide a secure grip. Tissue forceps (A) are used for grasping tissue with teeth or
serrations. Needle holders (C) have shorter, heavier jaws with a tungsten carbide
insert for holding needles. Scissors (D) have cutting edges. Retractors (E) are used
for exposure.
Question 2
Which of the following instruments is used to grasp tissue and has teeth at the tip?
A) Adson forceps
B) Kelly hemostat
C) Mayo scissors
D) Richardson retractor
E) Russian forceps
Correct Answer: A
,Rationale: Adson forceps are tissue forceps with teeth at the tip (Adson with teeth)
used for grasping tissue with a secure hold. Kelly hemostats (B) are used for
clamping vessels. Mayo scissors (C) are used for cutting heavy tissue. Richardson
retractors (D) are used for retraction. Russian forceps (E) have a round tip with a
central hole for grasping delicate tissue.
Question 3
A curved hemostat with horizontal serrations along the entire jaw and a box lock is
MOST likely a:
A) Crile hemostat
B) Kelly hemostat
C) Rochester-Pean hemostat
D) Mosquito hemostat
E) Allis clamp
Correct Answer: A
Rationale: A Crile hemostat is characterized by horizontal serrations along the
entire jaw length, a box lock, and a curved or straight design. A Kelly hemostat (B)
has serrations only on the distal half of the jaw. A Rochester-Pean hemostat (C)
has cross-hatched serrations and is larger. A mosquito hemostat (D) is smaller and
more delicate. An Allis clamp (E) has teeth for grasping tissue.
Question 4
Which retractor is a self-retaining retractor with multiple sharp prongs used to hold
back tissue?
A) Richardson retractor
B) Deaver retractor
C) Weitlaner retractor
D) Army-Navy retractor
E) Senn retractor
, Correct Answer: C
Rationale: A Weitlaner retractor is a self-retaining retractor with multiple sharp
prongs (usually 3x3 or 4x4 prongs) that hold tissue open without requiring an
assistant. Richardson (A) and Deaver (B) retractors are hand-held. Army-Navy (D)
is a hand-held retractor with two different-sized blades. Senn (E) is a hand-held
retractor with a single prong on one end and a flat blade on the other.
Question 5
Which instrument is used to hold a needle during suturing?
A) Hemostat
B) Tissue forceps
C) Needle holder
D) Scissors
E) Retractor
Correct Answer: C
Rationale: A needle holder is used to hold a needle during suturing. It has shorter,
heavier jaws with a tungsten carbide insert or cross-hatched pattern to securely grip
the needle. A hemostat (A) is used for clamping vessels and is not designed for
needle holding. Tissue forceps (B) are for grasping tissue. Scissors (D) are for
cutting. Retractors (E) are for exposure.
Question 6
Mayo scissors are BEST suited for cutting:
A) Delicate tissue
B) Suture material
C) Heavy tissue and fascia
D) Fine sutures
E) Skin only
